Why GAO Did This Study: 

Federal agencies that administer means-tested programs are responsible 
for both ensuring that people have appropriate access to assistance and 
ensuring the integrity of the programs they oversee. To balance these 
two priorities appropriately, it is important for agencies to have 
information on program integrity and program access. Knowing the 
proportion of the population that qualifies for these programs relative 
to the numbers who actually participate can help ensure that agencies 
can monitor and communicate key information on program access. 

To better understand participation in low-income programs, this report 
provides information on: (1) the proportion of those eligible who are 
participating in 12 selected low-income programs; (2) factors that 
influence participation in those programs; and (3) strategies used by 
federal, state, and local administrators to improve both access and 
integrity, and whether agencies monitor access by measuring 
participation rates. 

What GAO Found: 

For 12 federal programs supporting low-income people, we found that the 
proportion of those eligible who are enrolled varies substantially both 
between and within programs. Among entitlement programs—those programs 
that provide benefits to all applicants that meet program eligibility 
criteria—these rates range from about 50 to more than 70 percent. Among 
non-entitlement programs—those with limited funding—these rates ranged 
from less than 10 percent to more than 50 percent. While it may be 
neither feasible nor desirable for programs to serve 100 percent of 
those eligible for benefits, information on the share of those eligible 
who are enrolled in means-tested programs and on particular recipient 
groups such as the elderly or families with children, can help program 
managers more effectively address issues related to program access. 
However, participation rate estimates must be interpreted carefully 
because of limitations in the data sources and estimation methodologies 
used to calculate the estimates. 

Many factors influence access to low-income programs—including the type 
of benefits, ease of access, misperceptions about program requirements, 
and application and eligibility verification procedures. These factors 
can impact not only the share of eligible people who participate in low-
income programs, but other aspects of program access as well, including 
the composition of the program caseload and how programs work together 
to serve low-income individuals and families. 

Federal, state, and local administrators have implemented many 
strategies to achieve the goals of access and integrity, but federal 
agencies generally put more emphasis on tracking information and 
outcomes related to program integrity than program access. To better 
ensure that program administrators achieve program integrity goals, 
agencies have begun to develop measures to track and report on program 
integrity. Federal agencies have developed participation rate estimates 
for several low-income programs, but only four—CCDF, food stamps, WIC, 
and EITC—either currently collect and report information on the extent 
to which they are reaching their target populations or plan to do so. 
Such information can guide administrators in setting priorities and 
targeting scarce resources, even among programs that were not intended 
to serve everyone eligible for program benefits.

The Honorable John M. Spratt, Jr.: 
Ranking Minority Member: 
Committee on the Budget: 
House of Representatives: 

Dear Mr. Spratt: 

Each year through more than 80 means-tested programs, the federal 
government provides benefits and services to individuals and families 
with low incomes--just 12 of which account for as much as $330 billion 
in annual federal expenditures. As stewards of these funds, federal 
agencies have many roles, among them: to ensure that people have 
appropriate access to this assistance and to ensure the integrity of 
these programs by guarding against improper payments and unqualified 
participation. These responsibilities can be complementary, but they 
can also be practiced in ways that work at cross purposes. Outreach 
without appropriate screening, for example, can result in service to 
the wrong recipients, but cumbersome enrollment procedures can 
discourage those who qualify from applying. To meet requirements 
related to the Improper Payments Information Act of 2002, federal 
agencies administering these programs will be required to institute new 
steps to assure integrity by annually measuring and reporting improper 
payments. As they step-up efforts to ensure integrity, they will be 
challenged, as well, to ensure appropriate access. Without a sense of 
the proportion of the population that qualifies for these programs 
relative to the numbers who actually participate, however, it may be 
difficult for most agencies to know whether they have struck an 
appropriate balance in the weight of their strategies and whether they 
need to pursue methods that better serve both access and integrity. 

To better understand participation in low-income programs, we have 
agreed to provide you information on: (1) the proportion of those 
eligible who are participating in 12 selected low-income programs; (2) 
the factors that influence participation in those programs; and (3) 
strategies used by federal, state, and local administrators to improve 
both access and integrity, and whether agencies monitor access by 
measuring participation rates. The 12 programs included in this review 
are among the largest and were selected to cover a range of benefits 
and services aimed at supporting needy families and individuals. They 
include: the Child Care and Development Fund (CCDF), the Earned Income 
Tax Credit (EITC), the Special Supplemental Nutrition Program for 
Women, Infants, and Children (WIC), the Food Stamp Program, the 
Supplemental Security Income program (SSI), the Head Start program, the 
Pell Grant program, the Medicaid program, the State Children's Health 
Insurance Program (SCHIP), the Temporary Assistance for Needy Families 
(TANF) program, the Housing Choice Voucher (HCV) program, and the 
public housing program. 

To address our research objectives, we compiled estimates of the 
proportion of those eligible who participate in each of the programs 
for the most recent year for which data were available[Footnote 1] 
using different methodologies. We refer to this proportion as a 
participation rate when discussing entitlement programs and other 
programs that provide program benefits to all eligible applicants: 
EITC, food stamps, Medicaid, Pell Grants, and SSI. We refer to it as a 
coverage rate when discussing non-entitlement programs that do not 
necessarily provide benefits to all eligible individuals who apply for 
the program: CCDF, Head Start, Housing Choice Vouchers, Public Housing, 
SCHIP, TANF, and WIC. For seven programs, we contracted with the Urban 
Institute to provide us with information about their microsimulation 
model estimates of participation rates.[Footnote 2] These model 
estimates are also used to calculate estimates of the potential cost of 
serving eligible nonparticipants in a subset of programs. For the 
remaining programs, we provide participation or coverage rate estimates 
based on administrative and national survey data. We held discussions 
with federal agency officials to discuss the reliability of program 
data used in our estimates, reviewed related documentation, and ensured 
that the agencies conducted tests of the data for omissions and errors. 
In addition, we reviewed literature on factors that influence 
participation in the 12 programs covered by the review and strategies 
to improve program access and program integrity. We surveyed and 
interviewed the federal agencies that administer the 12 programs on 
factors they have identified that influence program participation and 
on strategies they have implemented to improve program access and 
program integrity. In addition, we interviewed federal, state, and 
local program administrators of various programs in California, 
Connecticut, Georgia, Maryland, and Minnesota, on factors that affect 
participation and strategies they have employed to address the goals of 
program access and program integrity. These states were chosen on the 
basis of innovative programs and initiatives related to program 
integrity and program access and demographic and geographic diversity. 
We performed this work between November 2003 and January 2005 in 
accordance with generally accepted government auditing standards. See 
appendix I for additional information on scope and methodology. 

Results in Brief: 

For 12 federal programs supporting low-income people, we found that the 
proportion of those eligible who are actually enrolled varies 
substantially both between programs and among subgroups enrolled in a 
single program. Given the differences in the goals, design, 
administration, and funding of the 12 programs, it is not surprising 
that we found substantial variation in these proportions. For 
entitlement programs--those designed to support all those who qualify-
-the estimated proportion of eligible people who were enrolled ranged 
from about 50 percent to more than 70 percent. For example, 
approximately three-quarters of those who were eligible took advantage 
of the Earned Income Tax Credit program in 1999, the most recent year 
for which data were available. For non-entitlement programs--those with 
limited funding and not necessarily intended to cover all eligible 
persons--the estimated proportion of the eligible who were enrolled 
ranged from less than 10 percent to more than 50 percent. In the Head 
Start program, for example, funded enrollment was sufficient to cover 
half of all potentially eligible children in 2003. Within some 
programs, we found that some subpopulations were enrolled in different 
proportions than other groups. For example, in the Food Stamp Program, 
the participation rate for families with children was higher than the 
participation rate for other groups. Some evidence shows that enrollees 
tended to be those among the eligible who had greater needs--as 
indicated by the levels of assistance for which they qualified. While 
information on participation rates can help program managers more 
effectively address issues related to program access, several factors 
must be taken into consideration when interpreting this information. 
For example, because of limitations of the data and methodologies used 
to measure rates of participation, we could not make statistically 
reliable comparisons across programs nor could we describe fluctuations 
over time for most programs. 

The size and type of program benefits, ease of access, misperceptions 
about program requirements and eligibility verification requirements 
put in place to ensure program integrity can affect program access in 
both entitlement and non-entitlement programs. For example, agency 
officials told us that participation in the WIC program is highest 
among infants in part because infants are eligible for the highest 
benefits, but that factors such as extended office hours can also 
impact participation. The factors we identified can affect several 
aspects of program access, including not only the number of program 
participants, but also the extent to which programs reach the total 
population eligible for benefits and services, how well agencies are 
allocating resources among targeted subpopulations, and, from an 
agencywide or even governmentwide perspective, how well specific means-
tested programs complement and interact with programs that serve 
similar populations or provide for similar needs. While concerns about 
the allocation of scarce resources and interactions with other programs 
apply to all low-income programs, they may be of particular importance 
to non-entitlement programs whose participation is limited by funding 
constraints. Participation or coverage rate information can guide 
program administrators in setting priorities and targeting scarce 
resources, even among programs that were not intended to serve everyone 
eligible for program benefits. 

Federal, state, and local administrators have implemented a variety of 
strategies to achieve both program access and program integrity, but 
federal agencies generally put more emphasis on tracking information 
and outcomes related to program integrity than program access. Through 
federal agency surveys and site visits, we identified several 
strategies currently being used that have the potential to achieve two 
of the fundamental goals common to all means-tested programs--program 
access and program integrity. These strategies ranged from innovative 
use of information technology to special outreach programs; some were 
in use nationwide and others were state or local efforts. The 
initiation and control of these strategies is often beyond the direct 
control of the federal agencies managing the programs. However, federal 
managers do play a role in that they encourage and facilitate such 
strategies, even in the most decentralized program, by emphasizing the 
importance of program access and program integrity--even absent 
specific related laws or regulations related to these issues. The 
Improper Payments Information Act of 2002 has built upon existing 
governmentwide efforts to emphasize to federal agencies the importance 
of having an internal control framework to address program integrity 
issues. At the same time, internal controls are important management 
tools to ensure that agencies meet their basic goals of reaching 
eligible families. The federal agencies that oversee these entitlement 
and non-entitlement programs can benefit from having up-to-date 
information on the extent to which their programs reach eligible 
individuals. However, while all of the programs we reviewed have begun 
to take steps to measure the extent of improper payments and all make 
efforts to assess how well their programs are working, only four of the 
programs we covered in this review--CCDF, food stamps, WIC, and EITC--
either currently collect and report information on the extent to which 
they are reaching their target populations in key performance and 
program reports or plan to do so. 

To better ensure that agencies have information on program access, we 
recommend to the Secretaries and Commissioners whose programs do not 
currently use participation rate information to consider the use of 
participation rate information in managing their programs. We also make 
some technical recommendations on how the usefulness of these measures 
could be improved. The agencies generally agreed with these 
recommendations. 

Background: 

The federal government funds a wide array of programs intended to 
provide benefits or services to low-income individuals, families, and 
households. The 12 programs included in this review include the largest 
of these programs, Medicaid, as well as some relatively small programs 
such as WIC. The 12 programs are administered by seven different 
federal agencies.[Footnote 3] Table 1 shows the agencies responsible 
for each program and federal expenditures for fiscal year 2003, the 
most current year available.

Source: Federal agency officials. 

[A] This includes the total amount of federal expenditures in fiscal 
year 2003, which is the most recent year for which these data were 
available. It includes current and prior year federal funds expended in 
fiscal year 2003; it does not include state expenditures. 

[B] This includes both credits paid out in refunds and reduced tax 
liabilities. 

[C] This includes funding for the housing choice voucher and moderate 
rehabilitation programs. 

[D] This includes expenditures for the public housing capital fund, the 
public housing operating fund, and revitalization of severely 
distressed public housing (HOPE VI). 

These programs provide different benefits and services to different 
target populations. Some of the programs provide benefits that phase 
out gradually, so some people may be eligible for a very low benefit. 
For example, in fiscal year 2005, monthly food stamp benefits for a 
three-person household can be as low as $1 per month. Other programs, 
such as Medicaid, generally offer comparable benefits to every resident 
of a state who meets eligibility requirements. Table 2 provides a brief 
description of each of the programs covered in this report and the 
types of benefits offered by each program. 

Table 2: Descriptions of 12 Low-Income Programs: 

Program: CCDF; 
Description: The Personal Responsibility and Work Opportunity 
Reconciliation Act of 1996 (PRWORA) authorized CCDF to help provide 
child care to low-income families and to give states more flexibility 
to design child care policies. CCDF is funded through an annual block 
grant to states and required state funds and may also include transfers 
from TANF. States are permitted to transfer up to 30 percent of their 
TANF block grant to CCDF. Under CCDF, child care services are available 
to eligible families through certificates or contracts with providers, 
and parents may select any legally operating child care provider, 
including home-based or center-based providers. 

Program: EITC; 
Description: EITC is a refundable federal tax credit available to 
eligible workers earning relatively low incomes. Because the credit is 
refundable, a person does not need to owe taxes to receive benefits. 
EITC is based on earned income, adjusted gross income, and the presence 
of qualifying children, if any. Under current law, there are three 
categories of EITC recipients: childless adults, adults with one child, 
and adults with two or more children. 

Program: Food Stamps; 
Description: The Food Stamp Program is the primary source of nutrition 
assistance for many low-income households. It enables eligible low-
income households to buy nutritious food with electronic benefit cards 
at authorized retail food stores across the country. State and local 
welfare offices operate the program, and the federal government 
oversees the state operation of the program. Participants must meet 
income and resource standards and be U.S. citizens or eligible non-
citizens, and all able-bodied individuals between 16 and 60 without 
dependents must register for work, take part in an employment and 
training program, or accept or continue suitable employment. Households 
with incomes are expected to spend about 30 percent of their income, 
after certain deductions, on food. 

Program: Head Start; 
Description: Head Start provides comprehensive developmental services 
for low-income, pre-school children ages 3 to 5, and social services 
for their families. Services can be provided through either a half-day 
or a full-day program. Head Start provides diverse services in four 
components: education, health, parent involvement, and social services. 
Grants are awarded to about 1,400 local public or private non-profit 
agencies, and the community must contribute about 20 percent of the 
total cost of a Head Start program. 

Program: Housing Choice Vouchers; 
Description: The Housing Choice Voucher program is the federal 
government's major program for assisting very low-income families, the 
elderly, and the disabled with their housing needs. HUD gives public 
housing agencies the funds to administer the program. Participants use 
vouchers to find their own housing, including single-family homes, 
townhouses and apartments. The voucher recipient pays the difference 
between the actual rent charged by the landlord and the amount 
subsidized by the program. Generally, the subsidy allows the tenant to 
pay no more than 30 percent of adjusted monthly income towards the rent 
and utilities. 

Program: Medicaid; 
Description: Medicaid (title XIX of the Social Security Act) is a 
federal/state entitlement program that generally provides health 
insurance coverage for low-income families and individuals who are aged 
or disabled. Medicaid is the largest source of funding for medical and 
health-related services for America's poorest people. Within broad 
federal guidelines, each state can (1) establish its own eligibility 
standards; (2) determine the type, amount, duration, and scope of 
services; (3) set the rate of payment for services; and (4) administer 
its own program. Medicaid policies for eligibility, services, and 
payment are complex and vary considerably, even among states of similar 
size or geographic proximity. 

Program: Pell Grant; 
Description: The Pell Grant program provides grants (i.e., aid that 
does not have to be repaid) to needy undergraduates. It is the largest 
source of grant aid for postsecondary education attendance funded by 
the federal government and provided an estimated $13.1 billion to 
students in fiscal year 2004. Pell Grants are intended to be the 
foundation for all federal aid awarded to undergraduates and 
constituted an estimated 19 percent of all federally supported aid in 
fiscal year 2004 that benefited postsecondary education students. For 
fiscal year 2004-2005, grants ranged from $400 to $4,050. 

Program: Public Housing; 
Description: Public housing was established to provide decent and safe 
rental housing for eligible low-income families, the elderly, and 
persons with disabilities. Public housing comes in all sizes and types, 
from scattered single family houses to high-rise apartments for elderly 
families. HUD contributes both capital and operating funds to local 
housing agencies that manage the housing for low-income residents at 
rents they can afford. HUD also furnishes technical and professional 
assistance in planning, developing, and managing these developments. 

Program: SCHIP; 
Description: As part of the Balanced Budget Act of 1997, Congress 
created SCHIP as a federal/state partnership, similar to Medicaid, with 
the goal of expanding health insurance to low-income children--i.e., 
those children whose families earn too much money to be eligible for 
Medicaid, but not enough money to purchase private insurance. States 
can (1) use SCHIP funds to expand Medicaid eligibility to children who 
previously did not qualify for the program; (2) design a children's 
health insurance program entirely separate from Medicaid; or (3) 
combine both the Medicaid and separate program options. 

Program: WIC; 
Description: WIC provides supplemental foods to low-income women, 
infants, & children up to age 5 who are at nutritional risk. The WIC 
target population consists of low-income, nutritionally at risk: 
pregnant and breastfeeding women; nonbreastfeeding postpartum women; 
infants (up to 1st birthday), and children up to their 5th birthday. It 
provides supplemental nutritious foods, including infant formula; 
nutrition education and counseling at WIC clinics; and screening and 
referrals to other health, welfare and social services. 

Program: SSI; 
Description: The SSI program, title XVI of the Social Security Act, was 
enacted in 1972 and implemented in 1974 to ensure a minimum cash income 
to all aged, blind, or disabled persons. SSI is provided to eligible 
individuals or couples who have limited income and resources (the 
countable resource limit is $2,000 for an individual and $3,000 for a 
couple). Federal SSI benefits are paid from federal general revenues, 
but many states also supplement payments. 

Program: TANF; 
Description: The Personal Responsibility and Work Opportunity 
Reconciliation Act of 1996 (PRWORA) replaced Aid to Families with 
Dependent Children (AFDC) with TANF, which marked the end of federal 
entitlement to assistance. TANF ended unlimited matching funding for 
family cash welfare and created fixed-block grants to states. The block 
grant covers benefits, administrative expenses, and services targeted 
to needy families and gives states great flexibility to design their 
own TANF programs. PRWORA imposed a 5-year limit on TANF cash 
assistance paid with federal funds and required states to achieve 
minimum participation rates in federally recognized work activities. In 
addition, they must spend a specified amount of state funds on eligible 
low-income families--at least 75 percent of the state funds they spent 
in fiscal year 1994, known as the maintenance-of-effort requirement. 
States may use these funds to pay for separate state programs.

Program Administration: 

The programs covered by this review represent both entitlement and non-
entitlement programs; programs that are administered entirely by 
federal agencies and those that are administered through federal 
partnerships with state and/or local agencies; programs that allow 
substantial state and local variation and those that provide uniform 
benefits throughout the country. Table 3 summarizes the level of 
government with whom responsibility for funding and design resides for 
each of the 12 programs.

Program Performance Management: 

Although state and local agencies responsible for administering several 
of the programs have some control over program design and 
implementation, primary responsibility for setting priorities, guiding 
policy, and measuring performance rests with the federal agencies that 
oversee the programs. The programs covered by this review may have many 
different goals and objectives of varying degrees of importance, but 
all of these programs--regardless of size, target population, funding 
structure, or types of benefits offered--were established to assist 
persons with limited income, and as such, all were tasked with the 
overarching goal of reaching and serving those eligible for program 
benefits or services. Likewise, all means-tested programs share the 
common goal of ensuring that the funds allocated for program benefits 
are provided only to those eligible. 

A key factor in achieving desired program outcomes, including program 
access and program integrity, is the implementation of appropriate 
internal control. As discussed in our prior work on this topic, 
internal control is an integral component of an organization's 
management that provides reasonable assurance that agencies are 
achieving outcomes related to the effectiveness and efficiency of 
operations and compliance with laws and regulations, among other 
things.[Footnote 4]

Federal agencies have several key management tools and program reports 
that they use to provide information about the programs they 
administer, develop policy, help with management decision-making, and 
help focus program administrators at all levels of government on 
achieving the federal agency's highest priorities. For example, through 
their strategic and annual performance plans and accountability 
reports, federal agencies set program goals, measure program 
performance against those goals, and report publicly on their progress. 
Some programs also issue annual or biennial reports to Congress on 
specific programs they administer; these generally include important 
program information. 

A number of governmentwide initiatives have resulted in increased 
emphasis by program managers on program integrity issues, including OMB 
guidance, the President's Management Agenda, GAO's High-Risk series and 
the Improper Payments Information Act of 2002 (IPIA). The IPIA requires 
the head of each federal agency to annually review all programs and 
activities that the agency administers and to identify all such 
programs and activities that may be susceptible to significant improper 
payments.[Footnote 5] For each program and activity identified, the 
agency is required to estimate the annual amount of improper payments 
and submit those estimates to Congress before March 31 of the following 
applicable year. OMB guidance then directs federal agencies to include 
a measure of improper payments in their annual Performance and 
Accountability Reports. All 12 programs we reviewed are subject to 
these requirements. 

Use of Federal Low-Income Assistance Varies Greatly by Program and by 
Subgroup: 

The proportion of those eligible who are actually enrolled in 12 
selected low-income programs varies substantially both between and 
within programs, but several factors must be considered to understand 
the implications of this information for program access. The estimated 
proportion of eligible people who were enrolled in entitlement 
programs--those designed to support all those who apply and qualify--
ranged from about 50 percent to more than 70 percent. In contrast, the 
estimated proportion of the eligible who were enrolled in non-
entitlement programs--those with limited funding and not necessarily 
intended to cover all eligible persons--ranged from less than 10 
percent to about 50 percent. Within programs, we found that 
subpopulations were enrolled in different proportions. Some evidence 
also suggests that enrollees in some programs, such as the Food Stamp 
Program, tend to be those who are eligible for larger benefit amounts. 

For Entitlement Programs, the Proportion of Those Eligible Who Were 
Enrolled Ranged from about 50 Percent to More Than 70 Percent, but 
Participation Rates Are Higher among Some Groups: 

For four of the five entitlement programs we examined, the proportion 
of eligible people who were enrolled varied from around 50 percent in 
the Food Stamp Program to more than 70 percent in the EITC and SSI 
programs; and within programs, different types of participants, such as 
children or the elderly, were enrolled in varying proportions.[Footnote 
6] Table 4 provides estimated participation rates for each of these 
programs, expressed in ranges to reflect potential errors in sample 
survey data. The actual participation rates may be outside the range of 
estimates shown because some types of uncertainty in the estimation of 
participation rates cannot be quantified. Estimates for the Food Stamp, 
Medicaid and SSI programs were developed by the Urban Institute under 
contract with HHS and Food Stamp Program estimates were developed by 
Mathematica Policy Research, Inc., under contract with USDA. HHS and 
USDA are the only two agencies to regularly estimate participation 
rates in low-income programs. We estimated the EITC participation rate 
for 1999. However, we were unable to estimate an enrollment rate for 
the Pell Grant program because of concerns about the reliability of 
some of the data needed to estimate the rate.

Urban Institute's TRIM3 model and Mathematica Policy Research, Inc. 

[A] All estimates are for the calendar year indicated in the table, 
except the food stamp estimates created by Mathematica, which are for 
fiscal year 2002. 

[B] This range represents a 95 percent confidence interval based on 
estimated sampling error in the national survey data. This interval 
does not take into account errors introduced by the modeling process or 
by administrative data. We assessed but did not quantify these errors. 

[C] The EITC participation rate shown has a sampling error that does 
not exceed plus or minus 2.7 percentage points. The number of eligible 
tax filers used in this estimate was adjusted to exclude those who 
received EITC benefits in error. The participation rate is a 
conservative estimate based on 32 percent of EITC dollars being claimed 
in error; the IRS estimated between 27 and 32 percent of these tax 
dollars were paid in error in 1999. Because more recent information 
about EITC payment errors is not available, we were unable to provide a 
more recent estimate. However, Congress has enacted new tax laws and 
the IRS has taken steps to improve compliance. For more details, see 
GAO, Earned Income Tax Credit Participation, GAO-02-290R (Washington, 
D.C.: Dec. 14, 2001). 

[D] While the Urban Institute and Mathematica each generate food stamp 
participation rate estimates using data from the CPS, their estimates 
differ slightly. The differences arise primarily from differences in 
imputation methodology for data missing from the CPS--such as assets, 
immigration/refugee status, and information on which household members 
buy and prepare food together. 

[E,F] Confidence intervals are not available. These estimates are from 
Mathematica Policy Research, Inc., Trends in Food Stamp Program 
Participation Rates: 1999 to 2002. (Washington, D.C.: Sept. 2004). 

[G] Estimates do not include individuals who are institutionalized. 
Estimates do account for variation in state eligibility rules and for 
people who may be eligible for only part of the year. 

[H] We were unable to estimate a participate rate for the Pell Grant 
program because we were unable to assess the reliability of data on the 
family income of students that did not apply for federal financial 
assistance. 

[I] No reliable national survey data exist on individuals who meet the 
SSI disability criteria. Therefore, researchers made assumptions about 
a person's disability based on self-reported information on inability 
to work due to illness or other disability, lack of work activity in 
the prior year, and receipt of disability income. Some of those assumed 
eligible for SSI based on disability may not meet the criteria and vice 
versa. As a result, the models may overestimate or underestimate the 
number of eligible people. This estimate also does not include 
institutionalized individuals and disabled children. 

[End of table]

These estimates indicate that between half and three quarters of those 
eligible are participating in four of the entitlement programs. 
Although differences in years, data sources, and estimation 
methodologies make it inappropriate to compare participation rates 
across programs, these estimates provide a general sense of the extent 
to which programs are reaching those eligible for benefits. 
Specifically, we found: 

* For the EITC program, we estimated in prior work that about 75 
percent of eligible households took advantage of this credit in 1999. 
This estimate was adjusted to account for tax dollars that were 
distributed in error that year.[Footnote 7] However, Congress has 
enacted new tax laws and the IRS has taken steps to improve EITC 
program compliance. 

* Two organizations, the Urban Institute and Mathematica Policy 
Research, Inc., have estimated food stamp participation rates using 
different methodologies but both found that about 48 percent of 
eligible households participated in this program in 2001 and 2002, 
respectively. In addition, Mathematica found that 54 percent of 
eligible individuals were enrolled in 2002. 

* An estimated 66 to 70 percent of eligible, noninstitutionalized 
people were enrolled in Medicaid in 2000. This estimate does not 
include institutionalized people, such as those in nursing homes. 

* We were unable to estimate Pell Grant participation rates because we 
were unable to assess the reliability of available data on the family 
income of enrolled students who did not apply for federal financial 
aid. 

* For SSI, an estimated 66 to 73 percent of eligible adult individuals 
and married couples received benefits in 2001. This estimate also does 
not include institutionalized people or disabled children. 

* Participation rates also can vary substantially even within a single 
program. Disaggregating program participation rates by targeted 
subpopulations can help us to better understand the implications of 
overall program participation rates. In table 5, we provide 
participation rate estimates for selected subgroups within the four 
entitlement programs for which we have participation rate estimates. As 
in table 4, these estimates are expressed in ranges to reflect 
potential errors that result from using sample survey data. (See the 
footnotes to table 5 for more details.)

[A] All estimates are for the calendar year mentioned. 

[B] This range represents a 95 percent confidence interval based on 
estimated sampling error in the national survey data. This interval 
does not take into account errors introduced by the modeling process or 
by administrative data. We assessed but did not quantify these errors. 

[C] The number of eligible tax filers used in these estimates were 
adjusted to exclude those who received EITC benefits in error. The 
participation rate is a conservative estimate based on 32 percent of 
EITC dollars being claimed in error; the IRS estimated between 27 and 
32 percent of EITC dollars claimed in 1999 were paid in error. Because 
more recent information about EITC payment errors is not available, we 
were unable to provide a more recent estimate. However, since 1999, 
Congress has enacted new tax laws and the IRS has taken steps to 
improve compliance. For more details, see GAO, Earned Income Tax Credit 
Participation, GAO-02-290R (Washington, D.C.: Dec. 14, 2001). 

[D] The EITC participation rate for all households has a sampling error 
that does not exceed plus or minus 2.7 percentage points. 

[E] The EITC participation rate for households with no children has a 
sampling error that does not exceed plus or minus 3.9 percentage 
points. 

[F] The EITC participation rate for households with one child has a 
sampling error that does not exceed plus or minus 7.7 percentage 
points. The actual participation rate cannot exceed 100 percent. 

[G] The EITC participation rate for households with 2 children has a 
sampling error that does not exceed plus or minus 8.3 percentage 
points. The actual participation rate cannot exceed 100 percent. 

[H] The EITC participation rate for households with 3 or more children 
has a sampling error that does not exceed plus or minus 8.3 percentage 
points. 

[I] Estimates in the table are from the Urban Institute. Mathematica 
has also estimated participation rates for these subgroups and found 
that about 66 percent of eligible households with children and 28 
percent of those with elderly members participated in fiscal year 2002. 
While the Urban Institute and Mathematica each generate food stamp 
participation rate estimates using data from the CPS, their estimates 
differ slightly. The differences arise primarily from differences in 
imputation methodology for data missing from the CPS--such as assets, 
immigration/refugee status, and information on which household members 
buy and prepare food together. 

[J] Estimates do not include individuals who are institutionalized. 
Estimates do account for variation in state eligibility rules and for 
people who may be eligible for only part of the year. 

[K] Estimates include those who are dually enrolled in Medicare and 
Medicaid who thus qualify for the full Medicaid benefit and those who 
only receive Medicaid assistance for their Medicare cost sharing. 
Estimates do not include eligible elderly people who are 
institutionalized. The participation rate may be lower for this group 
in part because those over the age of 65 may have Medicare coverage. 

[L] No reliable national survey data exist on individuals who meet the 
SSI disability criteria. Therefore, researchers made assumptions about 
a person's disability based on self-reported information on inability 
to work due to illness or other disability, lack of work activity in 
the prior year, and receipt of disability income. Some of those assumed 
eligible for SSI based on disability may not meet the criteria and vice 
versa. As a result, the models may overestimate or underestimate the 
number of eligible people. This estimate also does not include 
institutionalized individuals or disabled children. 

[M] Estimates do not include eligible elderly people who are 
institutionalized. 

[End of table]

As shown, participation in low-income programs varies markedly across 
subgroups. For example, a smaller share of elderly people eligible for 
low income programs tend to participate in the Food Stamps and Medicaid 
programs than among the total eligible population. The elderly may 
participate in the Food Stamp Program at a lower rate than other 
households because most elderly households receive Social Security and 
are eligible for relatively small food stamp benefits. For example, in 
2000, 44 percent of all households with elderly members eligible for 
food stamps were eligible for a monthly benefit of only $10 or less, 
the minimum benefit for households of one or two persons. In 
comparison, 12 percent of households without elderly members eligible 
for food stamps receive benefits that low. Similarly, Medicaid 
participation among the elderly may be low because Medicare also covers 
many elderly people who are eligible for Medicaid. In contrast, 
families with children tend to participate in food stamps, Medicaid, 
and the EITC at higher than average rates than those households without 
children.[Footnote 8] Although we were unable to disaggregate 
participation rates by geographic area, program participation rates can 
also vary by state or locality. 

Information on trends in program participation rates over time can also 
help in interpreting participation rate estimates, but we were only 
able to provide information on trends in participation for one program. 
Mathematica Policy Research, Inc., estimates food stamp participation 
rates annually under contract with USDA and has taken steps to ensure 
that estimates are comparable over time. As shown in figure 1, food 
stamp participation rates remained fairly stable between fiscal years 
1999 and 2002, declining slightly from 52 percent in fiscal year 1999 
to 48 percent in fiscal year 2002 among eligible households and 56 
percent in fiscal 1999 to 54 percent in fiscal year 2002 among eligible 
individuals.

to 2002:

[End of figure]

We were not able to provide information on trends in participation 
rates for the Medicaid and SSI programs because the most recent 
participation rate data available for these programs is not comparable 
to prior year estimates. While prior year estimates are available, 
because of changes from 1 year to the next in the methodology used to 
estimate participation rates, estimates for prior years are not 
perfectly comparable with the most recent estimates and are therefore 
not shown in this report. The participation rate estimate for the EITC 
was available for only 1 year. 

For Non-Entitlement Programs, the Proportion of Those Eligible Who Were 
Enrolled Ranged from Less Than 10 Percent to about 50 Percent: 

Among the seven non-entitlement programs we reviewed, the share of 
those eligible who participate ranges from less than 10 percent to 
about 50 percent. These programs are generally not funded to serve all 
eligible applicants, and many have other design features, such as the 
prioritization of certain subgroups and eligibility criteria specific 
to a state or locality, that would not necessarily allow for all 
eligible people who apply to receive benefits.[Footnote 9] 
Consequently, we refer to these estimates as coverage rates rather than 
participation rates. Table 6 provides estimated coverage rates for each 
of these programs, expressed in ranges to reflect potential errors in 
survey data. The actual coverage rates may be within a broader range of 
estimates than shown because other errors that may have resulted from 
calculating these estimates could not be quantified. Estimates for the 
CCDF, SCHIP, and TANF cash assistance programs were developed by the 
Urban Institute under contract with HHS. We also include a WIC estimate 
developed by the National Research Council, and another WIC estimate 
developed by the Urban Institute under contract with us. We estimated 
the Head Start and housing programs using administrative and national 
survey data.

CPS and HUD. 

[A] This range represents a 95 percent confidence interval based on 
estimated sampling error in the national survey data. This interval 
does not take into account errors introduced by the modeling process or 
by administrative data. We assessed but did not quantify these errors. 

[B] The estimates account for variations in state eligibility criteria 
and are based on criteria as of October 2001. Estimates do not account 
for participation in other programs that provide similar services. 

[C] To increase the precision of these estimates, 3 years of CPS data 
were used to estimate the eligible population; other coverage rates and 
participation rates estimated using TRIM3 only use 1 year of data. As a 
result, the confidence interval based on the sampling error is smaller 
than for the other estimates. 

[D] Head Start participation is measured by the number of funded slots, 
not the number of children in the program. Therefore, this estimate may 
overstate or understate the actual coverage rate because more than one 
child may fill a slot in a year and some slots may go unfilled. 
Estimates do not account for participation in other programs that 
provide similar services. 

[E] The coverage rate does not include enrolled children living above 
the poverty threshold. Nonpoor children can comprise up to 10 percent 
of Head Start enrollment slots. 

[F] HUD's data on the number of eligible households was based on the 
American Housing Survey. This survey may overestimate household income 
and underestimate the number of households in poverty. These estimates 
also may include households who do not qualify for the voucher despite 
their low-income status. Coverage rates are based on the number of 
households who successfully leased units in 1999. A total of 1,649,645 
vouchers were authorized, but some of these were not used partially due 
to voucher-holders' inability to find housing. Rates reflect only those 
participating in the Housing Choice Voucher program; however, those 
eligible may also be served by a number of other federal, state, and 
local housing assistance programs. 

[G] HUD's data on the number of eligible households was based on the 
American Housing Survey. This survey may overestimate household income 
and underestimate the number of households in poverty. Income-eligible 
households may not be eligible for other reasons--for example, local 
public housing authorities may deny assistance to people with habits 
and practices that may be detrimental to other public housing tenants-
-and the estimate does not account for this. Coverage rates are based 
on the number of public housing units that were leased; a total of 
1,235,229 units were available but some were unleased for a variety of 
reasons, such as resident turnover. Rates reflect only those 
participating in the public housing program; however, those eligible 
may also be served by a number of other federal, state, and local 
housing assistance programs. GAO used an eligible population of those 
who earn less than 80 percent area median income as per the eligibility 
criteria; however, nationally the vast majority of those served by 
public housing make less than 50 percent of the area median income. 

[H] A new program established in 1997, SCHIP saw its enrollment 
increase 75 percent between fiscal years 2000 and 2003; a more recent 
estimate of the SCHIP coverage rate would likely be higher than the 
range shown. In addition, because states' implementation of their 
programs varied, awareness of SCHIP may lag in states that created 
their programs more recently. 

[I] Estimates account for variation in state eligibility rules, and the 
estimates are based on state eligibility rules in place in 2000. 
Children who are eligible for Medicaid expansion SCHIP programs and 
separate state SCHIP programs are included in the estimate. Children 
covered by private and other public health insurance such as Medicaid 
are generally not eligible for SCHIP and are, therefore, not included 
in the denominator for the calculation; to the extent that some are 
included in the actual caseload under "employer buy in" programs, the 
coverage rate will be slightly overestimated. 

[J] Estimates account for variation in state eligibility rules. All 
units receiving TANF cash assistance are included, even though a 
separate state program might fund their benefits. Families receiving 
non-cash benefits funded by TANF are not included, although an 
increasing proportion of TANF funds are being used to provide non-cash 
assistance to families. Some families or individuals that may appear 
eligible according to model may not be participating because they have 
not complied with program requirements, such as being involved in work 
activities. However, those who have reached their state or federal TANF 
time limit are appropriately excluded from eligibility in estimating 
the coverage rate. 

[K] Estimates only include eligible infants and children, even though 
pregnant, postpartum, and breastfeeding women are eligible for this 
program, because the CPS does not have data to determine a woman's 
pregnancy status or whether she is breastfeeding. According to the FNS, 
women account for a quarter of WIC participants. 

[L] A confidence interval is not available. This estimate is based on 
data from National Research Council of the National Academies, 
Estimating Eligibility and Participation for the WIC Program 
(Washington, D.C.: Sept. 2003). Estimates include pregnant women, 
infants, and children. It does not include postpartum and breastfeeding 
women. 

[M] Estimates are preliminary because they are partially based on the 
numbers used to create Medicaid participation rates and SCHIP coverage 
rates. The Medicaid participation rate and SCHIP coverage rate for 2001 
had not been completed in time to include in this report. 

[End of table]

Generally less than half of those eligible participate in the seven non-
entitlement programs. Coverage rates also have limitations such as data 
sources, and estimation methodologies that make it inappropriate to 
compare the estimates across programs. However, they provide a general 
sense of the extent to which these programs are reaching eligible 
people. Specifically, we found: 

* Almost 20 percent of children who meet state-defined eligibility 
criteria are receiving child care services through CCDF.[Footnote 10] 
This estimate does not reflect participation in child care funded by 
other federal sources. HHS estimates that about 26 percent of CCDF-
eligible children are receiving child care services through either CCDF 
(including the Child Care and Development Block Grant, state CCDF funds 
or TANF transfers to CCDF), or child care services funded directly 
through the Social Services Block Grant (SSBG), TANF, or TANF state 
funds.[Footnote 11]

* The Head Start program funded enough slots to serve about 44 to 54 
percent of eligible 3-to 4-year-old low-income children in 
2003.[Footnote 12]

* An estimated 13 to 15 percent of households eligible for Housing 
Choice Vouchers on the basis of income both received a voucher and were 
able to successfully lease a housing unit in 1999, the most recent year 
for which these data were available. In addition, less than 10 percent 
of households eligible on the basis of income were served through the 
Public Housing program in 1999. While HCV and public housing are the 
two largest federal housing programs, there are other federal, state, 
and local housing programs from which eligible households could receive 
assistance. HUD estimated that in 1999 about a quarter of all 
households eligible for any kind of housing assistance received 
assistance. 

* In 2000, about 44 to 51 percent of eligible children participated in 
SCHIP. Since 2000, SCHIP enrollment has increased by nearly 3 million 
children, but the impact this has had on the coverage rate is not known 
because information on how the eligible population may have changed 
over this time period is not available. In addition, because states' 
implementation of their programs varied, awareness of SCHIP may lag in 
states that created their programs more recently. 

* About half of all eligible households receive cash assistance through 
TANF. This estimate does not account for families that receive other 
services, such as transportation and child care, that are offered 
through this program, but who do not receive cash assistance.[Footnote 
13]

* WIC participation rates were available from two sources. The National 
Research Council using the Survey of Income and Program Participation 
found that 51 percent of eligible infants, children ages 1 to 4 and 
pregnant women were enrolled in WIC in 1998. The Urban Institute, using 
the Current Population Survey, found that about 51 to 55 percent of 
eligible infants and children participated in 2001. 

Coverage rates for these programs can also vary substantially by 
subgroup, and they do vary within the TANF and WIC programs, the only 
non-entitlement programs for which we have this information. 
Understanding the extent to which different subgroups are covered by 
non-entitlement programs can be particularly important precisely 
because these programs are not necessarily funded to cover all those 
eligible. Table 7 provides coverage rates for groups of people eligible 
for TANF cash assistance and WIC.

[A] Estimates account for variation in state eligibility rules. All 
units receiving TANF cash assistance are included, even though a 
separate state program might fund their benefits. Some families or 
individuals that may appear eligible according to the model may not be 
participating because they have not complied with program requirements, 
such as being in involved in work activities. However, those who have 
reached their state or federal TANF time limit are ineligible and are 
not included, unless receiving assistance through a separate state 
program. 

[B,C] Estimates only include families with one parent or no parents 
present. 

[D] Estimates are preliminary because they are partially based on the 
numbers used to create Medicaid participation rates and SCHIP coverage 
rates. The Medicaid participation rate and SCHIP coverage rate for 2001 
had not been finalized during the time frames of this report. 

[E] Estimates only include eligible infants and children, even though 
pregnant, postpartum, and breastfeeding women are eligible for this 
program, because the CPS does not have data to determine a woman's 
pregnancy status or whether she is breastfeeding. According to the FNS, 
women account for a quarter of WIC participants. 

[End of table]

As shown, families with no income earners tend to receive TANF cash 
assistance at a higher rate in the TANF program than families with 
earners or two-parent families. The data also suggest that families 
with immigrants have a lower coverage rate than families without 
immigrants. As noted earlier, some families within these subpopulations 
may be receiving other services funded by TANF, although data are not 
available on this. The participation rate among infants eligible for 
WIC is higher than among children ages 1 to 4. 

We were unable to provide estimates of changes in coverage rates over 
time for most of the non-entitlement programs covered in this review, 
but we did find an increase in the coverage rate for the Head Start 
program over the past several years. Since 1997, Head Start coverage 
rates have increased from about 40 percent to 50 percent. However 
during this time period, the coverage rate increased between 2000 and 
2001 from about 50 percent to 58 percent and then gradually declined. 
The coverage rate increased by this amount within 1 year because slots 
increased by nearly 40,000 for the Head Start program while the number 
of children eligible decreased by about nearly 130,000. Since 2001 the 
number of funded Head Start slots has increased, but the coverage rate 
fell because the child poverty rate, and thus the number of eligible 
children, increased. Figure 2 shows Head Start coverage rate estimates 
for 1997 to 2003. 

Figure 2: Head Start Coverage Rate Estimates for 1997 to 2003:

[End of figure]

Because of changes in the methodology used to estimate coverage rates 
from 1 year to the next, we cannot reliably compare the most recent 
coverage rate estimates for SCHIP and TANF to those of prior years, but 
there is compelling evidence that coverage rates for these two programs 
changed significantly over time. SCHIP was first implemented in 1997 
and the number of children in the program grew from 660,351 in fiscal 
year 1998 to over 3 million in fiscal year 2000. As states continued to 
reach out to eligible children in subsequent years, participation 
continued to increase to nearly 6 million in fiscal year 2003. This 
eightfold increase in the number of children enrolled in SCHIP since 
fiscal year 1998 almost certainly had a significant impact on the 
coverage rate. Meanwhile, as states implemented welfare reforms during 
the strong economy of the late 1990s and other changes occurred in 
programs serving low-income families, the number of families receiving 
TANF cash assistance declined, falling by about 50 percent between 
fiscal years 1997 and 2003.[Footnote 14] This also likely had a 
significant impact on the program coverage rate. HHS has reported that 
about 70 percent of families eligible for TANF cash assistance were 
enrolled in the program in 1997, compared to less than 50 percent in 
2001, but we were unable to quantify how much of this change was caused 
by changes in estimation methodology.[Footnote 15] It is also important 
to note that states' TANF programs have changed over this time. States 
have more flexibility in the types of non-cash assistance they may 
provide families, and some families eligible for cash assistance may be 
receiving other forms of aid instead. In addition, some families or 
individuals that may appear eligible according to the model may not be 
participating because they have not complied with program requirements, 
such as being involved in work activities. 

The Estimated Costs of Serving Eligible Non-participants Show That in 
Some Programs, Those Eligible for the Largest Benefits Are More Likely 
to be Enrolled: 

Our estimates of the costs of providing benefits to eligible non-
participants show that for some programs, those currently participating 
in the programs are generally eligible for a greater benefit amount 
than those not participating. For these programs, the estimated costs 
of serving those eligible but not currently receiving benefits may be 
less than one might expect based on the participation or coverage rates 
we estimated. This is not surprising, as it makes sense that, for 
example, a person eligible for a $10 food stamp benefit might be more 
likely to forgo that benefit than a person eligible for a $150 benefit. 
More specifically, Mathematica found that the 48 percent of households 
participating in the Food Stamp Program in fiscal year 2001 received 
about 62 percent of the total amount of benefits that would be paid out 
if all eligible households received benefits. 

As shown in table 8, we were able to estimate the additional cost of 
providing benefits to eligible nonparticipants for 6 of the 12 programs 
we reviewed. These cost estimates take into consideration the 
characteristics of non-participants and the benefits for which they 
would be eligible but do not account for increases in administrative 
costs that could result from participation increases. We were unable to 
estimate the cost of providing benefits to eligible, non-participants 
in the six other programs--CCDF, HCV, Medicaid, Pell Grants, Public 
Housing, and SCHIP--because we did not have enough information to 
determine how the characteristics of the non-participants would have 
affected the benefit amounts they could have received. 

Table 8: Potential Cost of Providing Benefits to Eligible Non-
participants for the Most Recent Year Data Were Available: 

Program (year): EITC (1999); 
Potential annual cost of serving eligible non-participants[A,B]: $2-
3.4[C].

Note: Cost estimates do not include increases in administrative costs

[A] This range represents a 95 percent confidence interval based on 
estimated sampling error in the national survey data. This interval 
does not take into account errors introduced by the modeling process or 
by administrative data. We assessed but did not quantify these errors. 
Estimates are based on most of the same data used to estimate 
participation and coverage rate estimates for the related programs and, 
therefore, many of the same data and model limitations apply. 

[B] Estimates do not account for policy or economic changes that would 
occur if participation in these programs increased. All estimates are 
based on the assumption that participation in other programs remains 
constant. 

[C] Estimates are from GAO, Earned Income Tax Credit Participation, GAO-
02-290R (Washington, D.C.: Dec. 14, 2001). 

[D] Estimate is based on an average cost per slot multiplied by the 
number of non-participating eligible children. This estimate does not 
account for local variation in the cost of services, and does not 
account for the possibility of more than one child filling a slot. 

[E] Estimates are only for the additional cost of providing TANF cash 
assistance. The program provides other supports, such as child care and 
transportation, to needy families, and the cost of these services would 
increase the estimate if they were included. 

[F] Estimates are only for the additional cost of providing food 
benefits to infants and children who are not enrolled. 

[End of table]

Although Medicaid is by far the largest program we reviewed, developing 
reliable estimates of the costs of serving those eligible but not 
enrolled in the Medicaid program is difficult for a number of reasons. 
These reasons include a lack of information about the health status of 
eligible non-participants, the many variables that affect health care 
costs, and the open-ended nature of health care benefits. 

The costs included in the table do not reflect the total costs that 
would be incurred if all eligible people enrolled in these programs. 
Probable increases in administrative costs that would be incurred are 
not included, and we did not estimate how the cost of goods and 
services offered through the Food Stamp, Head Start, and WIC programs 
would change if more participants were demanding them. However, the 
costs do include some additional costs that would be incurred by states 
in programs where states are required to cover some of the program 
costs. 

Recognizing the differences in goals, design, administration, and 
funding in the 12 programs, it may be neither feasible nor desirable to 
provide program benefits to all those eligible. Because alternative 
programs could offer the similar benefits and services as the programs 
we reviewed, some of these programs, especially those with limited 
funding, may be best administered by only serving a certain subgroup of 
their eligible population. For example, in localities where school 
systems offer pre-kindergarten classes to 4-year-old children, Head 
Start programs may want to focus more on enrolling 3-year-olds from low-
income families. Also, limited administrative resources may prevent 
federal, state, and local agencies from serving all those eligible. 
Full participation among eligible people also may not be feasible 
because some choose not to enroll in means-tested programs. Given these 
constraints, some programs may focus on targeting their resources to 
those most in need of program services. 

Finally, while participation and coverage rate estimates as well as 
estimates of potential program costs provide important program 
information that can be useful to both policymakers and program 
administrators, these estimates must be interpreted carefully to take 
into consideration such factors as survey data, research methodology, 
timeliness of estimates, and the availability of alternative programs. 
These factors limit our ability to compare rates across programs and 
would need to be considered in efforts to define appropriate or desired 
participation or coverage rate levels. For a detailed discussion of the 
factors that affect use of these estimates, see appendix II. 

Many Factors Influence Participation but Their Impact on Entitlement 
and Non-Entitlement Programs Differs: 

Many factors influence access to means-tested programs, including the 
benefits provided by the program, ease of access, misperceptions about 
program requirements, and eligibility verification procedures put in 
place to ensure program integrity, based on our literature review and 
agency interviews. These factors influence participation by affecting 
the number of people who participate in a program as well as the type 
of people who participate. Entitlement programs may focus on addressing 
factors that affect access in order to increase program participation. 
However, because coverage rates in non-entitlement programs are 
determined primarily by funding levels, non-entitlement programs are 
more likely to be concerned about the impact of these factors on other 
aspects of program access, such as the composition of the program 
caseload and how the program interacts with alternative programs that 
provide similar benefits. 

The Size and Type of Benefits Can Affect Participation: 

The size and type of program benefits can affect whether or not an 
individual participates in a program. Numerous studies show that the 
size or value of the benefit influences program participation, and this 
depends largely on the structure of program benefits. Some programs, 
such as the Food Stamp Program, determine benefit levels based on 
income, allowing a three-person household to receive as little as $1 
per month depending on household income. Other programs, such as 
Medicaid, generally offer comparable benefits to every resident of a 
state who meets eligibility requirements. A recent National Bureau of 
Economic Research study showed that across a range of programs and 
within programs, larger benefits were associated with higher 
participation and coverage rates.[Footnote 16] In addition, our 
literature review, site visits, and analysis of participation rates for 
selected programs showed that participation and coverage rates tend to 
be higher among subgroups eligible for larger benefits. For example: 

* Elderly individuals are generally eligible for small food stamp 
benefits; their participation rate in the program is lower than for 
other groups. 

* Families with infants participate in WIC at higher rates than 
families with older children, in part because the value of the WIC 
voucher is greater for families with infants. WIC officials in 
Connecticut reported to us that 10 percent of families stopped 
participating in the program when their youngest child reached age 
1.[Footnote 17]

* On average, families with children who are eligible for the EITC 
receive a higher EITC benefit than individuals and families without 
children, and they participate at a higher rate. 

The type of benefits offered can also influence whether someone 
eligible for a program participates. Some programs--such as EITC and 
SSI--offer cash benefits while other programs--such as Head Start and 
Medicaid--offer direct services, such as educational or health 
services. Our research on participation in low-income programs 
generally shows that participation and coverage rates are higher among 
programs that provide cash benefits than among programs that provide 
direct services. One reason for this difference is the flexibility cash 
benefits give to individuals. Although the recipient may need the 
services provided by programs in which they are enrolled, these types 
of benefits do not allow individuals to shift resources away from 
program purposes toward what they might consider more pressing needs. 
Our site visits confirmed that the type of benefits influence 
participation and coverage rates. For example, we found that: 

* SSI recipients who participated in a pilot project that allowed them 
to receive their food stamp allotment in cash expressed a strong 
preference for this over traditional food stamp coupons. 

* Some individuals who need subsidized housing may prefer the Housing 
Choice Voucher program, which allows individuals to choose their 
housing in neighborhoods that offer better educational and employment 
opportunities or choose to remain in a place while paying less rent, 
over the Public Housing program that does not give the individuals 
flexibility to choose where they live. 

Ease of Access to Program Benefits and Services Can Influence 
Participation: 

Factors that influence the ease with which potential participants can 
access a program--including office hours, program location, and the 
ability of program participants to redeem or use their benefits--can 
also affect the number and groups of people who participate in the 
programs. Several of the programs we reviewed require applicants to 
visit the program office to establish and maintain eligibility. For 
instance, local WIC, TANF, and Food Stamp Program offices typically 
require face-to-face interviews before individuals can receive 
benefits.[Footnote 18] Those programs that keep traditional office 
hours--8:00 a.m. to 5:00 p.m.--pose a barrier to potential applicants 
who work and would have to take time away from their job in order to 
apply. Studies on child care and WIC programs identify traditional 
office hours as a barrier for working families. Similarly, Medicaid 
officials in California told us that one of their barriers to 
participation is office hours that do not accommodate working families. 
Although many program officials suggested that having flexible office 
hours is important to participants, some offices are challenged to 
extend their operating hours. WIC officials in Connecticut told us that 
they have attempted to promote extended hours and have made some 
progress; however, instituting extended hours remains problematic due 
to limited funding and contracts governing the workforce. 

The location of the program office can also affect participation and 
caseload composition. For many individuals--like the elderly, 
individuals with disabilities, and families living in rural areas--
traveling to a program office that is outside the limits of their 
available mode of transportation makes it difficult for them to receive 
needed benefits. The USDA published in its National Survey of WIC 
Participants that one of the top barriers in the WIC program is 
transportation with 30 percent of participants reporting that they 
missed appointments because they lack transportation to the office. 
Studies on the Housing Choice Voucher, child care, Head Start, and Food 
Stamp programs reported similar findings. Many state and local 
officials we visited agreed that transportation is a barrier to 
participation. A TANF, Food Stamp, and Medicaid official in Washington 
County, Maryland, told us that public transportation is limited and 
getting to and from the program offices poses a barrier to 
participation for many individuals, especially those in rural 
communities. According to officials, participants without vehicles have 
to seek rides from family members or acquaintances to access services. 
For many of these participants being seen going to the welfare office 
is difficult and sometimes stigmatizing. 

Some programs--including child care, Housing Choice Voucher, and 
Medicaid--offer benefits that can be difficult for participants to use, 
as some service providers--landlords, day care workers, or health care 
providers--will not exchange their services for program benefits. For 
example, our prior work found that the proportion of providers who will 
accept child care subsidies varied widely by state, ranging from 23 to 
90 percent. Even in cases where providers accepted subsidies, the 
number of slots for children that used child care subsidies was 
limited.[Footnote 19] Additionally, several state and local officials 
suggested that participants are sometimes challenged to find health 
care providers that accept Medicaid. According to officials in Chisago 
County, Minnesota, participants have to drive up to 200 miles to visit 
a dentist that accepts Medicaid. 

Misperceptions about Program Requirements Discourage Some Individuals 
from Participating: 

From our literature review and interviews with program officials, we 
also found that many individuals do not participate in low-income 
programs because they do not know that they are potentially eligible 
for benefits. Numerous studies have documented instances where 
participation was compromised because individuals were unaware of 
program benefits or had misconceptions about eligibility. For example, 
several EITC, Medicaid, Food Stamp, Head Start, and SSI studies 
indicate that one of the primary barriers to participation is that 
individuals do not know that they are eligible for these benefits. For 
some individuals--like the elderly and non-English speakers--this 
unfamiliarity with program benefits is even more widespread, creating a 
larger barrier to participation and an under representation of these 
individuals in the caseload. Many program officials we visited agreed 
and explained that individuals also have misconceptions about program 
eligibility. For example, some individuals do not believe that they are 
eligible for benefits because they are employed while others do not 
want to be attached to the perceived stigma associated with the 
programs. In Los Angeles, Medicaid officials noted that rumors 
circulated about the eligibility criteria for Medicaid prevent many 
potential recipients from applying for the program. Particularly in non-
English speaking communities, information about social services is 
often received through word of mouth; thus, when incorrect information 
circulates, it can have a significant impact on participation. 

Application Process and Eligibility Verification Requirements to Ensure 
Program Integrity Can Have an Effect on Participation: 

Eligibility verification requirements--rules put in place to improve 
program integrity by ensuring that only those eligible for program 
benefits receive them--can also affect the overall number and 
characteristics of people who participate in the program. Each low-
income program in this study has a set of verification requirements 
that individuals must complete to establish and maintain eligibility. 
Common requirements among the programs include completing application 
forms and providing necessary documentation. In addition, some programs 
require applicants to take additional steps, such as attending face-to-
face interviews, documenting parental or spousal assets, or 
participating in orientation classes. According to our literature 
review, the complexity of verification requirements can impact the 
number of enrollees, especially for individuals with mental 
disabilities or who are homeless. One WIC study reviewed participation 
rate differences among states and found that states that required 
applicants to provide proof of income (before it was federally 
mandated) and had stricter program rules had lower program 
participation than states that did not require income 
documentation.[Footnote 20] Additionally, another study examined EITC 
participation rates across states and found that differences in 
participation rates are due in part to the applicant having help 
completing the complex tax forms.[Footnote 21] Many state and local 
officials agree that strict and/or complicated verification 
requirements can decrease participation, particularly among certain 
groups of people. For example, we found: 

* According to officials, the Pell Grant application is very long and 
complicated and can be difficult for students and their parents to 
complete. Staff from an organization in St. Paul, Minnesota, dedicated 
to assisting low-income students to access higher education told us 
that many low-income students in the area would not be able to complete 
the forms correctly without their assistance. 

* CCDF Officials in Connecticut and Georgia told us that the 
application process can be complex and difficult for applicants and, as 
a result, many applicants submit their applications late or incomplete. 
Because there is very high demand for child care subsidies, these 
families are often denied benefits or removed from the waiting list. 

* Local SSI officials told us that participants face many life changes 
such as frequent hospitalization and institutionalization, moving into 
different family households, and changes in the hours that they work. 
To remain eligible for program benefits, SSI recipients must report 
these types of changes within 10 days from the end of the month of the 
change. 

Finally, while each program has its own set of verification 
requirements, these requirements become even more challenging when 
participants are applying or maintaining eligibility for multiple 
programs. Program officials in Maryland told us that one of the biggest 
barriers to accessing multiple means-tested programs is the many 
different eligibility criteria and reporting requirements of the 
various programs. According to state officials in Maryland, the TANF 
and Food Stamp Programs are relatively well aligned, but Medicaid has 
not coordinated as much with the other programs. According to 
officials, this can be problematic because a participant who is turned 
down for one program might assume that he or she is ineligible for 
other low-income programs and may fail to apply for benefits for which 
they are eligible. 

Factors That Influence Participation Rates Can also Impact Other 
Aspects of Program Access Such As Targeting and Program Interactions: 

Factors that influence participation also impact other aspects of 
program access such as targeting and program interactions among all low-
income programs, but particularly among non-entitlement programs whose 
enrollment levels are determined largely by funding levels. The non-
entitlement programs covered in this review--CCDF, Head Start, Housing 
Choice Vouchers, Public Housing, SCHIP, and TANF--have funding 
limitations that could restrict the total number of people who could 
potentially participate in the programs and, as a result, coverage 
rates for these programs may be determined, at least in part, by 
funding. However, among programs that allow states substantial 
flexibility in determining program eligibility and implementation such 
as CCDF, SCHIP, and TANF, funding constraints contribute to, but do not 
determine coverage rates to the extent that they do for programs that 
allow less state and local flexibility. Given funding constraints for 
non-entitlement programs, agencies are challenged to allocate scarce 
resources appropriately by targeting their benefits to specific groups 
of people and planning strategically to ensure that the program 
complements a broader range of programs administered by the same agency 
or that provide similar services or benefits to the program's eligible 
population. 

Because factors that influence participation often affect the 
composition of a program's caseload, some agencies that administer 
programs with limited funding have put measures in place to ensure that 
their caseloads reflect program priorities--whether that involves 
targeting certain groups or ensuring that benefits do not 
disproportionately favor or exclude certain subpopulations. For 
example, although the public housing program generally does not target 
benefits to households with the lowest incomes, it allows priority to 
be given to elderly and disabled recipients. Agency officials reported 
that they track participation of these groups to ensure that their 
share of the total caseload does not change dramatically from 1 year to 
the next. Similarly, state child care officials told us that funds are 
generally provided to recipients based on priority groups that favor 
families receiving public assistance and those with the greatest 
financial need. 

Additionally, many agencies are cognizant of how their programs 
interact with and complement other programs that serve the same 
population. For example, some child care programs pair with half-day 
Head Start programs to provide continuous care to children of working 
parents; Medicaid and SCHIP programs within some states coordinate 
their enrollment processes to facilitate access to health insurance for 
individuals in the state; and between 1998 and 2003, HUD responded to a 
decrease in the number of public housing units available for low-income 
households by increasing resources available through its voucher 
program to maintain coverage for families. Likewise, in allocating TANF 
resources, programs often coordinate with local workforce development 
agencies, child care programs, and other programs that provide similar 
services to best meet the needs of their clients without duplicating an 
existing effort. In these ways, programs acknowledge and respond to 
access issues and ways in which factors affect access other than 
participation levels and rates. 

Program Administrators Have Strategies That Improve Both Access and 
Integrity, but Federal Agencies Have Generally Focused More on 
Measuring Program Integrity Outcomes: 

Program administrators have implemented many strategies to achieve 
desired program outcomes, including those related to program access and 
program integrity, but while agencies have generally taken steps to 
monitor and disseminate information on program integrity, few track and 
report on the extent to which they are serving their eligible 
populations. The programs we reviewed have many goals and objectives of 
varying degrees of importance to the agencies that administer them, 
among them program access and program integrity. Strategies implemented 
at the federal, state, and local level to address these two issues 
include information systems, data sharing, and technological 
innovation, changes to the application and eligibility verification 
process, and outreach and coordination with other programs. Although 
federal agencies do not have direct control over many of the strategies 
we identified--including those mandated by law and those initiated at 
the state and local level--federal managers can play a role in 
encouraging and facilitating such strategies by emphasizing program 
access and program integrity as federal agency priorities. In response 
to the Improper Payments Information Act of 2002, all of the federal 
agencies we reviewed have taken at least some steps to identify and 
begin reporting information to Congress and others on the extent of 
improper payments. We also found, however, that for several of the 
programs we reviewed, federal agencies have not taken steps to identify 
and use participation or coverage rate information in managing their 
programs. Having up-to-date information on the extent to which their 
programs reach eligible individuals can help agencies plan 
strategically, set priorities, and ensure that agencies are reaching 
eligible families. 

Programs Have Found Ways to Improve Access by Reducing the Burden on 
Applicants While at the Same Time Improving Program Integrity: 

The state, local and federal program officials we spoke with identified 
several strategies that they believe may improve either of the two 
objectives--program access or program integrity--without harming, and 
in many cases improving, the other. As mentioned, some efforts to 
increase program integrity and prevent fraud, such as increasing the 
amount of eligibility verification required, may actually hurt access 
to the program by deterring even those eligible from applying. However, 
program administrators told us of several strategies that increase 
access while maintaining and even improving integrity. The 
complementary strategies we identified are enabled by information 
systems, data sharing, and technological innovations, changes in the 
application and eligibility verification process, and outreach and 
coordination with other programs. 

Information Systems, Data Sharing, and Technological Innovation: 

Improved information systems, sharing of data between programs, and use 
of new technologies can help programs to better verify eligibility and 
make the application process more efficient and less error prone. These 
strategies can improve integrity not only by preventing outright abuse 
of programs, but also by reducing chances for client or caseworker 
error or misunderstanding. They can also help programs reach out to 
populations who may face barriers. One strategy involves sharing 
verified eligibility information about applicants across programs. Data 
sharing prevents applicants from having to submit identical 
verification to multiple programs for which they may be eligible, and 
it can also speed up the sometimes-lengthy application process. In 
addition, data sharing allows programs to check the veracity of 
information they receive from applicants with other databases. 

In Minnesota, WIC caseworkers are able at the time of application to 
determine participant eligibility by accessing basic eligibility 
information via technology systems from other means-tested programs, 
such as Medicaid, food stamps and TANF. SSI administrators told us that 
during the application interview, income data is entered in their 
computer system. This information is then checked with a number of 
other databases including those of the IRS, the Department of Veterans 
Affairs, and the state Civil Service Administration to quickly verify 
earnings and other eligibility requirements and inconsistencies are 
flagged. Similarly, Georgia has an interactive computer system that 
aggregates client information for TANF, Medicaid, and the Food Stamp 
Program and calculates benefits for all three programs. Additionally, 
when clients need to make a change in their eligibility information, 
these data are automatically changed for all three programs, so that 
clients can receive the appropriate level of benefits based on their 
most current eligibility information. Furthermore, the data reliability 
matches may include information from the Department of Labor wage 
match, SSI benefits, prison information, and information on a person's 
death. If any of the matched information conflicts with the information 
provided by the client, a caseworker is to ask additional questions of 
the client. In all these ways, caseworkers can accelerate the 
application process while capitalizing on verified eligibility 
information already provided to other programs. 

Some administrators told us that such data sharing, however, can be 
complicated by concerns over ensuring privacy and by insufficient 
technological capacity. Local program administrators told us that 
eligibility data for Medicaid and SCHIP is tightly controlled because 
of Health Insurance Portability and Accountability Act (HIPAA)--a law 
that limits access to an individual's health information--but that its 
data might be shared, if warranted, with proper consent. Data sharing 
can be impeded by technological limitations, such as computer systems 
that cannot communicate directly with other systems over the Internet 
or some other network, or a lack of software needed to translate 
information into formats that other computers can understand. Our prior 
work on data sharing identifies strategies agencies have implemented to 
address concerns about privacy and technological capacity 
issues.[Footnote 22]

Some agency officials told us of ways in which on-line applications can 
improve both access and integrity. As stated, program integrity is 
compromised not only by willful misrepresentation, but also by 
applicant and caseworker error. Web-based or partially web-based 
applications can automatically check that all required fields are 
completed before an application is submitted for review and 
automatically calculate benefits thereby reducing error. Moreover, 
having the option of an on-line application can increase access to 
those who are eligible for benefits but who may have difficulty 
physically getting to program offices. Minnesota has instituted an on-
line interactive application for Medicaid that program administrators 
believe will make the application process easier for both participants 
and caseworkers. In addition to making the process easier, the system 
will also check verification information with a variety of other data 
sources and thus reduce the likelihood of errors as well. In this way, 
a potentially burdensome application process becomes simpler, more 
accessible, and less error prone. Similarly, eight states accept food 
stamp applications through the Internet. Of course, this strategy is 
less viable or effective where access to computers is limited or where 
the on-line environment cannot be adequately secured. 

Application and Eligibility Verification Process Changes: 

Program administrators told us about several changes in the application 
and eligibility verification process that have improved their ability 
to promote access and ensure integrity. Efforts to increase the 
accuracy of eligibility and benefit determination can increase access 
by reducing the number of applicants who were incorrectly denied 
benefits or whose benefit determinations resulted in underpayments. For 
example, streamlining or simplifying the application and providing 
applications in other languages can increase access, but also promote 
program integrity by reducing errors or misunderstanding in the 
application process. Simplifying applications by clarifying confusing 
wording and removing redundant questions as well as providing 
applications in an applicant's native language can reduce the 
possibility of these types of errors. According to federal officials, 
most states use a simplified application form for the SCHIP program to 
remove application barriers for families. For example, the SCHIP 
program applications in both Connecticut and California have been 
reduced from 17 and 27 pages respectively to only 4 pages each without 
sacrificing required information, according to state officials. In many 
cases, the SCHIP streamlined application forms caused corresponding 
changes in state Medicaid applications as well. In addition, many of 
the program administrators with whom we spoke told us that their 
applications and forms were available in many languages. For example, 
the Minnesota Department of Revenue now has state EITC tax forms and 
fact sheets directing them to the federal EITC in eleven languages. 

Another way in which programs can streamline the application process is 
through categorical eligibility with other programs, which can be set 
at the federal or state level depending on the program. Categorical 
eligibility, also known as adjunctive eligibility, allows an individual 
who has been found eligible for one program to be automatically granted 
eligibility for another program, typically one with less stringent 
eligibility criteria. For example, if an individual is receiving SSI, 
federal legislation generally requires that that person be 
automatically eligible for Medicaid.[Footnote 23] Similarly, if a 
pregnant woman is receiving Food Stamps, Medicaid, or TANF, then she 
automatically qualifies for WIC benefits--and thus does not need to 
provide income verification once again when applying for the program. 
States also have flexibility to grant automatic eligibility for other 
programs. A state WIC program, for example, may grant automatic 
eligibility for families receiving Free and Reduced Price School 
lunches. These adjunctive or automatic eligibility policies allow 
ultimately for simpler applications, which may enhance access and 
reduce error. In fact, federal administrators at USDA noted that 
adjunctive eligibility is one of the most important tools now used to 
address program integrity and access issues in a way that cuts across 
programs. 

The provision of more comprehensive in-person assistance in filling out 
applications can encourage a candidate eligible for benefits to 
complete an otherwise lengthy, complicated, or intimidating application 
process. Such personal assistance can also prevent errors that result 
from misunderstanding of application questions or requirements or even 
fraud by reminding applicants in person that fraudulent claims are 
punishable by law. For example, to increase access to the program, 
California program officials told us that the SCHIP program developed a 
training process that certified staff from other entities, such as 
schools and community-based organizations, as "application assistants." 
These "application assistants" are also trained to recognize when 
applicants seem to be submitting false information and are prohibited 
from assisting families who have previously been found to have 
committed fraud. In a Maryland SSA office, SSI program administrators 
told us that they had abbreviated their application form so that most 
information is now collected in an interview. This process helps 
improve access for those with limited literacy or those who may be 
discouraged by a long paper application. Officials also noted that this 
process helps program integrity because the interviews allow 
caseworkers the opportunity to remind clients that fraudulent claims 
are punishable by law. Similarly, EITC officials in Minnesota told us 
that free tax preparation assistance could make the process less 
complicated for filers and could also cut down on fraud from tax 
preparers. As one official explained, many low-income families live 
near a high concentration of paid tax preparers, who have incentives to 
fraudulently file for a high credit. While more in depth application 
assistance has these benefits, it can pose challenges to programs in 
ensuring the quality of the assistance offered and it can be costly. 
According to California SCHIP officials, funding to train "application 
assistants" for the SCHIP program in California was ended in May 2002 
due to budget constraints. 

Lastly, some policies put in place to prevent fraud at the time of 
application can also help with program access. Connecticut Department 
of Social Services has begun a fraud prevention program, termed FRED 
(Fraud Early Detection), which was instituted to address an increase in 
the amount of fraud and error detected in the program. The purpose of 
FRED is to identify potential fraud cases before benefits are paid out 
to prevent improper payments rather than identifying fraud after the 
payments have been made. Under FRED, cases that meet 1 of 12 risk 
criteria are to be referred to a fraud investigator who is to visit the 
home within 10 days of the referral. While the investigator is visiting 
the home, he/she is to interview the client about aspects of the risk 
criteria, and make a recommendation regarding eligibility. While the 
primary purpose of the visit is to prevent fraud, in practice 
investigators have found that their role is also to explain the 
eligibility criteria more clearly to applicants and to explain what 
steps they need to take in order to be eligible for program benefits. 
In addition, investigators are trained to provide additional 
information to the family on other resources available to them and to 
assist them with referrals, thereby increasing access to an array of 
related social services. 

Outreach and Coordination with Other Programs: 

Targeted outreach to populations that might have more barriers to 
accessing the program has the potential to increase access without 
necessarily compromising integrity. Many program officials we spoke 
with told us that they had outreach strategies to reach out to 
populations--such as rural-dwellers, the elderly, or those with limited 
English proficiency--that have had trouble accessing the program. Such 
strategies include information sessions or pamphlets in ethnic 
community centers or partnering with advocacy groups. In addition, 
cross agency referrals for applicants already found to be eligible and 
more overall agency coordination can improve access without sacrificing 
integrity. 

Many agency officials with whom we spoke told us that they coordinated 
with other programs to reach potential clients. In Maryland, the 
Department of Social Services invites the Volunteer Income Tax 
Assistance program to work out of its office, so that those low-income 
earners already in contact with social services can have better access 
to the EITC. Some offices in California participate in an open door 
policy program in which clients can access any social service program 
through referrals at any state government office they walk in to. Some 
program administrators told us that program co-location can help 
increase access. This happens when an individual applying for one 
program in an office is referred to and immediately serviced by another 
program in that same location. Some examples we found had Food Stamps 
located in TANF offices and a WIC clinic collocated with the state 
Children's Health Insurance Program. 

Federal Agencies Have Taken Steps to Track Improper Payments, but Few 
Estimate Program Participation or Coverage Rates to Monitor Program 
Access: 

All of the programs we reviewed emphasize both program access and 
program integrity, and as we have described, many federal, state, and 
local program administrators have implemented strategies intended to 
achieve access and integrity goals. However, not all agencies 
responsible for administering these programs have established 
management practices, in keeping with standards of internal control, 
that will consistently guide them in achieving these outcomes. Among 
the standards that are particularly relevant for agencies responsible 
for administering means-tested programs are:[Footnote 24]

* establishing and maintaining a control environment, a culture of 
accountability that sets a positive and supportive attitude toward 
achieving management objectives;

* monitoring program performance over time; and: 

* recording and communicating relevant, reliable, and useful 
information to management and others who need it to carry out their 
internal control and operational responsibilities. 

To achieve desired program outcomes and safeguard federal funds, these 
standards should be part of an agency's operational and management 
practices. While the agencies we reviewed have taken steps to establish 
internal controls for improper payments and program integrity, not all 
have established similar controls for achieving desired program access 
outcomes. 

There are many ways in which federal agencies can establish a culture 
of accountability, one that "sets the tone" for program administrators 
at all levels of government to emphasize certain priorities. One way to 
do this is to monitor progress toward achieving desired program 
outcomes, and another is to effectively communicate program information 
in a broad sense, with information flowing down, across, and up the 
organization. Depending on the program, some aspects of an achievement-
oriented environment are codified in laws, regulations, and federal 
policies. For example, the Improper Payments Information Act of 2002 
requires those programs and activities susceptible to significant 
erroneous payments to calculate annual improper payment estimates and 
sets statistical sampling confidence and precision levels for 
estimating those payments. 

As shown in table 9, some of the federal agencies covered by this 
review have already begun to monitor improper payments for the programs 
they administer and, as directed by OMB guidance, communicate this 
information by including a measure of improper payments in their annual 
Performance and Accountability Reports.[Footnote 25] Including measures 
of improper payments in agency annual performance plans and 
accountability reports is one way to provide officials with important 
information on areas of success and areas that need improvement and to 
send a signal to all working on agency programs that the measured goal 
is a priority. (For information on the amounts of improper payments 
reported by agencies, see app.III.) To varying degrees, the other 
agencies included in this review have begun taking steps to identify 
and report on improper payments as well. While agencies are taking 
steps, much remains to be accomplished before a comprehensive picture 
is available of the amount of improper payments for these 
programs.[Footnote 26]

[End of table]

While an internal control framework is emerging for addressing 
financial program integrity issues, few of the agencies responsible for 
administering the programs we reviewed have established a similar 
framework for achieving desired program access outcomes, although they 
have implemented numerous strategies to increase program participation. 
The 12 programs we reviewed have numerous program goals and objectives 
of varying degrees of importance to the agencies that administer them. 
Because the most fundamental purpose of these programs is to serve low-
income individuals and families, all track measures that provide some 
information about program participation and access. For example: 

* All of agencies responsible for administering the programs we 
reviewed track the number of people participating in their programs. 

* Some federal agencies--such as HUD--measure the extent to which 
program participants redeem or use benefits provided to them. 

* Others use other measures related to access. CMS tracks the number of 
individuals who are uninsured each year. 

* Many agencies track participants and participant outcomes through 
program effectiveness studies.[Footnote 27]

Through these efforts, agencies have demonstrated their concern about 
program access, yet, the ways in which most of these agencies measure 
program participation do not inform administrators about the extent to 
which they are meeting overall need and therefore do not provide all 
the information they need to monitor access. As discussed above, access 
encompasses not only the number of program participants, but also the 
extent to which programs reach the total population eligible for 
benefits and services, how well agencies are allocating resources among 
targeted subpopulations, and, from an agencywide or even governmentwide 
perspective, how well specific means-tested programs complement and 
interact with programs that serve similar populations or provide for 
similar needs. While concerns about the allocation of scarce resources 
and interactions with other programs apply to all low-income programs, 
they may be of particular importance to non-entitlement programs whose 
participation is limited by funding constraints. Participation or 
coverage rate information can guide program administrators in setting 
priorities and targeting scarce resources, even among programs that 
were not intended to serve everyone eligible for program benefits. 

As shown in table 10, only one of the agencies we reviewed, USDA, 
regularly estimates participation rates for the programs it administers 
and communicates and disseminates information on these rates in a way 
that promotes a culture of accountability supportive of achieving 
program access outcomes. USDA has been estimating participation rates 
annually for the Food Stamp Program since 1975. The agency uses this 
information to get a better understanding of how well they are reaching 
certain priority subpopulations such as the working poor, single-parent 
families with children, and SSI recipients; 
and to identify states in need of outreach assistance. In addition, 
USDA has established a performance goal to increase participation rates 
in the Food Stamp Program and reports food stamp participation rates in 
its annual performance report.[Footnote 28] In these ways, the agency 
uses this information for program management purposes.

[End of table]

USDA has taken steps to develop a reliable participation rate measure 
for the WIC program and plans to estimate the WIC participation rate 
annually. Because the WIC program is not an entitlement and 
participation is determined by the appropriated funds, FNS officials 
told us they do not plan to establish a performance goal related to the 
WIC participation rate. However, officials told us that they do think 
it is important to monitor and report on the WIC participation rate for 
policy, planning, and budgeting purposes, and the agency plans to use 
these data in managing the program by highlighting the measure in the 
program's budget reports and its annual report to Congress. 

HHS plays a key role in estimating participation rates for several 
means-tested programs. Since 1973, HHS's Office of the Assistant 
Secretary for Planning and Evaluation has funded TRIM3 for the purposes 
of policy development, analysis, and research on such topics as the 
interactive effects of programs serving low-income families. The 
Welfare Indicators Act of 1994,[Footnote 29] requires HHS to submit 
annual reports to Congress on welfare receipt in the United States and 
key indicators and predictors of welfare dependence. These reports, 
produced annually since 1997, include participation and coverage rates 
from TRIM3 for TANF (and its predecessor program, Aid to Families With 
Dependent Children), SSI, and food stamps. 

HHS includes CCDF coverage rates[Footnote 30] in the biennial 
congressional report and plans to include a performance measure related 
to participation rates in its annual performance reports starting in 
fiscal year 2006. However, HHS generally does not use participation 
rate estimates it has available from TRIM3 in managing its other 
programs by highlighting the information in its annual performance 
plans or congressionally mandated program reports. For example, TANF 
participation rates are not included in the agency's TANF Annual Report 
to Congress and Medicaid and SCHIP participation and coverage rates are 
not included in any of the other congressionally mandated reports 
disseminated by CMS, the agency that administers these programs. 

Only one of the other agencies we reviewed, the IRS, has plans to 
estimate and report on participation rates for the programs they 
administer. IRS plans to begin estimating the participation rate in the 
EITC program on an annual basis starting in fiscal year 2005 and to use 
the EITC participation rate as a performance measure in its annual 
performance report. However, the other agencies we reviewed, including 
SSA, HUD, and ED, do not estimate participation or coverage rates for 
the SSI, Housing Choice Voucher, Public housing, or Pell Grant programs 
and reported no plans to do so.[Footnote 31]

There are several reasons agency officials cited for not collecting 
participation rate information. For some programs, information on 
certain eligibility criteria can be difficult or costly to obtain. For 
example, reliable data on the disability status of children who do not 
receive SSI is not readily available from national survey data. We were 
unable to provide a participation rate estimate for this group for this 
reason. Absent a legislative or other mandate to estimate participation 
and coverage rates, agency officials may not consider conducting such 
estimates a priority. However, some agency officials that do not 
regularly estimate participation or coverage rates indicated they would 
find such estimates useful. For example, HUD officials indicated that 
the agency finds its estimates of worst case housing needs, which 
include some coverage rate measures for all housing programs, useful 
for policy and planning purposes. Similarly, while Head Start officials 
do not publish or report coverage rate estimates in any agency 
documents, they indicated that they occasionally estimate participation 
rates informally for internal use in policy, planning, and budgeting. 

Conclusion: 

Federal agencies responsible for administering means-tested programs 
are charged with ensuring that those eligible for program benefits and 
services are able to access them and with ensuring prudent oversight of 
taxpayer dollars by maintaining program integrity, including preventing 
improper payments. Program administrators may find it challenging to 
achieve these goals in part because they may conflict--ensuring program 
integrity can potentially come at the expense of program access. While 
we identified a number of strategies that have been implemented by 
federal, state, and local agencies that could potentially achieve both 
of these goals, unless agencies track progress toward meeting these 
goals in a way that signals to program administrators at all levels of 
government that both access and integrity are federal priorities, there 
is a risk that one of the goals may be compromised. Estimating 
participation rates for means-tested programs is difficult--and more 
difficult for some than for others--and cannot be considered "an exact 
science." Nevertheless, when done rigorously--in a way that ensures 
that estimates are comparable over time and quantifies the errors that 
result from the estimation methodology--these estimates can provide a 
basic understanding of the extent to which needy populations are being 
served by federal programs and can be a key component of a federal 
agency's efforts to establish a culture of accountability that 
emphasizes the importance of program access. Federal agencies 
responsible for administering only four of the programs we covered in 
this review--CCDF, food stamps, WIC, and EITC--either currently collect 
and report information on the extent to which they are reaching their 
target populations in key performance and program reports or plan to do 
so. As a result, the federal agencies that administer the other nine 
programs covered by this review may lack data that could inform their 
budgetary and programmatic decisions, assist them in ensuring that 
their programs are coordinated with and appropriately complement other 
programs available to their target populations, help them to manage 
their programs effectively, and enable them to provide policymakers 
with the information they need to make decisions. 

Recommendations to Executive Agencies: 

Recommendations to the Secretary of the Department of Agriculture: 

As the department moves forward with participation rate estimates for 
the WIC program, we recommend that the Secretary: 

1. take steps to clarify to users the limitations of the estimates; 
and: 

2. comparability between estimates by reanalyzing data as estimation 
methodologies change, so that consistent methods are applied over time. 

Recommendation to the Secretaries of the Department of Education and 
the Department of Housing and Urban Development: 

To help ensure that agencies have information on program access, we 
recommend that the Secretaries of Education and HUD study the 
feasibility of calculating participation or coverage rates and 
including them in key program management reports. 

Recommendations to the Secretary of the Department of Health and Human 
Services: 

We recommend that the Secretary of HHS consider making some 
improvements to the participation and coverage rate information 
produced for the CCDF, Medicaid, SCHIP, and TANF programs, such as: 

3. quantifying errors that result from calculating these estimates to 
help users better understand the accuracy of the data; and: 

4. ensuring, to the extent possible, that estimates are comparable over 
time. 

We also recommend that the Secretary include participation and coverage 
rate estimates in key program reports for these four programs. 

We also recommend that the Secretary study the feasibility of 
estimating the coverage rate for the Head Start program on a regular 
basis and to include these estimates in key Head Start program reports. 

Recommendation to the Commissioner of the Internal Revenue Service: 

As the IRS moves forward on developing participation rate estimates to 
use as a program performance measure for the Earned Income Tax Credit, 
we recommend that the Commissioner of the Internal Revenue Service take 
steps to quantify errors that may result from estimating these 
participation rates to help users better understand the accuracy of the 
data and ensure that estimates will be comparable over time. 

Recommendation to the Commissioner of the Social Security 
Administration: 

To help ensure that the agency has information on program access, we 
recommend that the Commissioner consider the feasibility of providing 
participation rate information (from the existing source or another 
source) in SSA program management reports. 

Agency Comments: 

We provided drafts of this report to and received comments from the 
Departments of Agriculture, Education, Health and Human Services, and 
Housing and Urban Development; the Internal Revenue Service; and the 
Social Security Administration. They generally agreed with our 
conclusions and recommendations. Agency written comments appear in 
appendixes IV through VII. 

On February 3, 2005, we met with FNS officials to discuss their 
comments. The officials said they agreed with our conclusions and 
recommendations. They stated that they recognize the importance of 
tracking both program access and program integrity and their ongoing 
efforts to estimate participation rates in the food stamp program 
reflect their commitment to balancing the goals of access and 
integrity. They stated that as they move forward in developing a 
participation rate estimate for the WIC program, they plan to take 
steps to clarify to users the limitations of the estimates and to 
ensure that the estimates will be comparable over time. Agency 
officials also provided technical comments, which we incorporated in 
the report where appropriate. 

The Department of Education agreed that data sources now available 
would not provide sufficient information to develop a reliable 
participation rate estimate for the Pell Grant program. However, the 
department cited a study currently being conducted by the National 
Center for Education Statistics that will determine the feasibility of 
implementing a system of collecting data on all postsecondary students. 
This study will also provide information that could be used to examine 
the feasibility of estimating participation rates for the Pell Grant 
program. 

The Department of Health and Human Services provided comments related 
to each of the five programs under its jurisdiction. The department 
noted that it has taken steps to measure program access in the TANF, 
CCDF, Medicaid, and SCHIP programs through their funding of TRIM3, 
although they do not always report these estimates in key program 
reports. With regard to CCDF, HHS recognized the importance of coupling 
efforts to control improper payments with efforts to provide effective 
service delivery, and therefore access. The department noted that it 
has recently established a performance measure related to coverage 
rates for the CCDF program. We incorporated this information into the 
report. HHS also thought that we overstated the differences between 
CCDF and TANF in the impact of state flexibility on coverage rates so 
we changed that section of the report. With regard to TANF, HHS raised 
the concern that increasing coverage rates may conflict with other TANF 
program goals and consequently, coverage rates are not an appropriate 
performance measure for the TANF program. We recognize that increasing 
the coverage rate is not an explicit goal of TANF and believe this 
concern is consistent with the report's conclusion that increasing 
program access may not be feasible or desirable for some programs. 
Nevertheless, we continue to believe that including program 
participation and coverage rates in key program reports can help inform 
policymakers and program administrators at all levels of government and 
assist them making budgetary and programmatic decisions. In its 
discussion of SCHIP and Medicaid, HHS indicated that the report 
reinforced the agency's approach to promoting both access and 
integrity. The department noted that CMS is working to improve its 
coverage rate estimates for SCHIP and meanwhile, it continues to 
measure progress toward increasing coverage among children under 200 
percent of poverty, a proxy for the program coverage rate. 

HHS also highlighted several other issues that we believe are already 
sufficiently discussed in the report. These include the fact that not 
all those eligible and not participating need program services; that 
some programs allow states considerable flexibility in implementing 
programs and determining eligibility; that participation or coverage 
rates can be challenging to estimate accurately; and that uncertainties 
and limitations surrounding participation and coverage rate estimates 
should be made clear to users of this information. HHS also reiterated 
some of the limitations of our cost estimates and our Head Start 
coverage rate estimates. Agency officials also provided technical 
comments, which we incorporated in the report where appropriate. 

Department of Housing and Urban Development officials provided us with 
technical comments, which we incorporated in the report where 
appropriate. 

The Internal Revenue Service agreed with our conclusions and 
recommendation. The IRS recognizes the interactions between efforts to 
improve program access and those intended to improve program integrity, 
and as part of their efforts to utilize a balanced approach that 
emphasizes both goals, the IRS has recently established the EITC 
participation rate as a GPRA measure. As it moves forward in developing 
the EITC participation rate, the IRS plans to take steps to quantify 
errors that may result from estimating these participation rates to 
help users better understand the accuracy of the data and ensure that 
estimates will be comparable over time. Agency officials also provided 
technical comments, which we incorporated in the report where 
appropriate. 

The Social Security Administration agreed with our conclusions and 
recommendation. The agency noted that it has considered the feasibility 
of estimating participation rates in the past and has calculated 
participation rates among the elderly. However, the agency also noted 
that limitations of the national survey data make such estimates 
challenging for the SSI program. The agency agreed that estimating 
participation rates on a regular basis could provide an important 
management tool. 

As agreed with your office, unless you publicly announce its contents 
earlier, we plan no further distribution of this report until 30 days 
after its issue date. At that time we will send copies of this report 
to the Secretaries of the Departments of Agriculture, Education, Health 
and Human Services, and Housing and Urban Development; the 
Commissioners of the Internal Revenue Service and the Social Security 
Administration; relevant congressional committees; and others who are 
interested. Copies will be made available to others upon request, and 
this report will also be available on GAO's Web site at 
http://www.gao.gov.

Appendix I: Objectives, Scope, and Methodology: 

We designed our study to provide information on (1) the proportion of 
those eligible who are participating in 12 selected low-income 
programs; (2) the factors that influence participation in those 
programs; and (3) strategies used by federal, state, and local 
administrators to improve both access and integrity, and whether 
agencies monitor access by measuring participation rates. To obtain 
information on these issues, we compiled estimates of participation and 
coverage rates for each of the programs covered by the review for the 
most recent year for which data were available, we reviewed literature 
on participation in programs for low-income people, and we gathered 
information directly from both federal program officials and state and 
local administrators. To determine the completeness and accuracy of 
data obtained from various sources, we took several steps, described 
below, to assess the data and determined that the data were 
sufficiently reliable for use in this report. 

We performed this work between November 2003 and January 2005 in 
accordance with generally accepted government auditing standards. 

Participation and Coverage Rates: 

To obtain information on the proportion of those eligible who are 
participating in 12 selected low-income programs, we used information 
developed by the Urban Institute under contract with HHS about the 
participation and coverage rates they estimated for 7 programs--CCDF, 
Medicaid, TANF, food stamps, SCHIP, SSI, and WIC. Also, we estimated 
the coverage rates for the Head Start program using administrative data 
and CPS data and for the Housing Choice Voucher and Public Housing 
programs using data from a HUD report on worst case housing needs in 
1999. The participation rate estimate for the EITC program was from our 
previous work. In addition, we performed a literature review to obtain 
information about program participation and coverage rates that were 
estimated by other organizations. When possible, we obtained rates from 
1997 to the most recent year available, but as mentioned in the report, 
we did not present many estimates of rates prior to the most recent 
year available because changes in methodologies did not allow us to 
determine whether changes in the rates over time were actual changes in 
participation rates or resulted from changes to the estimation 
methodology. We were unable to provide a Pell Grant program 
participation rate because we were unable to assess the reliability of 
available data on the family income of students who did not apply for 
federal financial assistance, which is necessary for determining 
program eligibility. Table 11 summarizes the methodologies used to 
calculate participation and coverage rates for the 12 programs covered 
in this review.

coverage rate for any program will differ by whether average monthly or 
total numbers are used.

Participation and Coverage Rates Estimated by The Urban Institute: 

The Urban Institute estimated participation and coverage rates for 
CCDF, Medicaid, TANF, food stamps, SCHIP, SSI, and WIC under a contract 
with the Department of Health and Human Services (HHS). In order to 
evaluate the reliability of these data and to determine whether it met 
our standards for reporting quantitative information, we contracted 
with the Urban Institute to obtain additional information about these 
estimates and the methodologies used to calculate them, including the 
Transfer Income Model, version 3 (TRIM3). 

The TRIM3 microsimulation model was used to determine the number of 
people who would be eligible for a program if they applied. This model 
simulates the process that a caseworker would undergo to determine 
eligibility by reviewing individual or household characteristics such 
as household composition, income, disability, and other factors as 
appropriate for the programs. TRIM3 primarily relies on the Census 
Bureau's Annual Social and Economic Supplement to the Current 
Population Survey to estimate the eligible population. For some 
programs, this data source does not include all information needed to 
determine a person's or household's eligibility. For example, the data 
do not include information on the value of certain assets that might be 
considered during eligibility determination for some programs. In these 
instances, the Urban Institute researchers used TRIM3 to assign 
eligibility-related characteristics to individuals included in the CPS 
who they believed were likely to have them, a process referred to as 
imputation. The estimates of the eligible population were used as the 
denominators of the participation and coverage rates, and 
administrative data on the number of participants were generally used 
as the numerator. In general, groups excluded from the TRIM3 
eligibility estimate used for the denominator (such as those who are 
institutionalized) were also excluded from the administrative data used 
for the numerator. 

The CPS data limitations and the process of assigning characteristics 
may have resulted in errors in the estimates of the eligible population 
and, therefore, the participation and coverage rates for seven 
programs. These include sampling error, non-sampling error, error 
related to the imputation process, and error related to program 
implementation. GAO statisticians and social science analysts reviewed 
the Urban Institute's TRIM3 technical documentation, interviewed the 
Urban Institute researchers, requested additional TRIM3 calculations 
from the Urban Institute, and reviewed available academic and 
government literature on the sources of error in microsimulation models 
of low-income program participation to determine what errors existed. 
Although there are several types of potential errors, not all the 
errors could be quantified. 

* The CPS, like all sample surveys, is subject to sampling error. This 
error reflects the difference between (1) the results that are obtained 
from the members of the sample that are actually surveyed and (2) the 
results that would be obtained if each member of the population were 
surveyed. We contracted with the Urban Institute to calculate the 
sampling error of CPS data used in TRIM3, and we verified that they 
used the appropriate procedures to make these calculations. We used the 
estimates of sampling error provided by the Urban Institute to 
calculate a range for the most recent TRIM3 estimates at the 95 percent 
confidence level, and these ranges are presented in the report. 
However, the ranges underestimate the total error in TRIM3 estimates. 

* The CPS data used in TRIM3 are also subject to non-sampling error 
that has not been quantified. These errors can occur if survey 
respondents have difficulty interpreting a particular question, lack 
information necessary to answer a question, are uncomfortable with 
accurately reporting certain sensitive information, or do not answer 
certain questions, among other factors that affect data collection and 
measurement. Such non-sampling errors are likely to have affected 
variables that are used by TRIM3, such as labor force participation for 
example. According to a 2002 Census Bureau report, the 1996 CPS covers 
a smaller proportion of the Black population (84 percent) than it does 
of the White population (94 percent). The Census Bureau reported that 
this low coverage rate biases labor force estimates, because those who 
are left out of the sampling frame are quite different from those who 
are included in it. Yet, the full extent of non-sampling error in the 
CPS is unknown. 

* The process of assigning characteristics when CPS data are not 
available--the imputation process--also can produce error. In most 
instances, efforts were not made to quantify the error associated with 
these imputed data. However, a National Research Council (NRC) panel 
attempted to quantify such error when reviewing methods for estimating 
participation rates for WIC and found that estimates can vary 
noticeably depending on whether imputed or reported monthly income data 
are used to determine eligibility. During this review, the NRC panel 
compared TRIM-adjusted CPS data, in which monthly income is imputed on 
the basis of annual income, and Survey of Income and Program 
Participation (SIPP) data, in which monthly income is collected 
directly from survey respondents. 

* Specification error can result when the variables in a 
microsimulation model incorrectly represent the process for determining 
program eligibility that actually occurs between caseworkers and 
applicants. For example, in its TANF module, TRIM3 does not consider 
certain aspects of program eligibility, including specific work 
requirements, behavioral requirements such as school attendance and 
immunizations, and sanctions from failing to comply with work rules or 
child support rules. These exclusions could cause TRIM3 to overestimate 
eligibility and therefore underestimate participation and coverage 
rates. Similarly, while several means-tested programs base their 
eligibility on the federal poverty guidelines, there is no universal 
administrative definition of "family," or "household" that is valid for 
all programs that use the poverty guidelines. To the extent that 
federal programs use administrative definitions that differ somewhat 
from the statistical definitions used by the CPS, estimates of the 
eligible population could be affected. 

Participation and Coverage Rates We Estimated: 

We estimated the participation and coverage rates for the Head Start, 
Housing Choice Vouchers, Public Housing, and EITC (in prior work). 
These estimates are also limited by the data sources and assumptions of 
who may be eligible for these programs. The EITC and Head Start rates 
were estimated using the CPS and, therefore, estimates are subject to 
sampling and non-sampling errors mentioned earlier. In addition, 
because the CPS did not have complete information to determine who may 
be eligible for the EITC, we made assumptions about whether children 
were in a household long enough for them to be counted as a member for 
tax purposes. We also assumed that the lack of data on certain assets 
would not significantly affect participation rate estimates.[Footnote 
32] For Head Start, the administrative data did not allow us to 
determine the number of children who are actually served in the 
program. The data were only on the number of program slots funded, and 
more than one child can be served with each slot over the course of a 
program year if there is turnover in participation. However, for the 
purposes of calculating Head Start coverage rates, we assumed that only 
one child filled a slot. 

We used a HUD report on the households with worst case housing needs in 
1999 and administrative data to estimate the Housing Choice Vouchers 
and Public Housing coverage rates. HUD used data from the American 
Housing Survey in this report.[Footnote 33] We assessed the reliability 
of the survey data and determined that the data were sufficiently 
reliable for use in this report. In conducting this assessment, we 
reviewed Bureau of the Census studies on the survey. Census reported 
that the American Housing Survey underestimates income and 
overestimates poverty for households, variables used to determine the 
number of people with housing needs. We were unable to quantify the 
error this may have produced in the estimates. 

Reliability of Administrative Data: 

We determined that the administrative data used to estimate 
participation and coverage rates were reasonably reliable for this 
purpose. As a part of this assessment, we reviewed the data on the 
number of participants and we discussed this information with federal 
agency officials. However, with the exception of the EITC data, we did 
not adjust the number of participants to account for those who may have 
received program benefits and/or services in error. As a result, the 
administrative data could have produced errors in the estimates due to 
potential inaccuracies in reporting the number of eligible 
participants. 

Cost Estimates: 

To obtain the estimated cost of providing benefits to those eligible 
and not participating in the Food Stamp Program, SSI, TANF cash 
assistance and WIC, we contracted with the Urban Institute to provide 
us with these estimates. The organization used the TRIM3 model to 
estimate the total benefit amount for eligible non-participants, and 
these estimates were based on the amount that each individual or 
household would receive based on their characteristics. These estimates 
have similar limitations as their related participation and coverage 
rates, and not all of their errors could be quantified. 

The EITC cost estimate was based on our prior work,[Footnote 34] but 
the Head Start cost estimates were done during the course of this 
project. We estimated the potential costs for Head Start using 
administrative data on the average cost per slot and the number of 
eligible non-participating children we estimated using the CPS. We 
assume that only one child would be served with a slot, even though in 
actuality more one than can. We also did not account for variation in 
program cost at the local level, and we did not account for variation 
in local eligibility criteria. 

All of the estimates have two major limitations. We did not include the 
administrative costs of serving the non-participants; 
this would increase the cost estimates for all programs. For some 
programs, federal, state, and local governments would share these 
administrative costs. We also did not factor in policy or economic 
changes that may occur if participation increased in these programs. In 
addition, for all programs, we calculated the estimates for each 
program individually and we did not account for how changes in the 
participation for one program could influence benefit amounts in 
another. 

We were unable to estimate the cost of serving eligible, non-
participants in the five other programs--CCDF, HCV, Medicaid, Pell 
Grants, Public Housing, and SCHIP--because we did not have enough 
information to determine how the characteristics of the non-
participants would have affected the benefit amounts they could have 
received. 

Factors That Affect Participation and Strategies to Improve Access and 
Integrity: 

To obtain information about factors that affect participation and 
strategies to improve access and integrity for the 12 selected 
programs, we conducted a literature review, obtained documentation from 
federal officials, interviewed federal officials and interviewed state 
and local officials in California, Connecticut, Georgia, Maryland, and 
Minnesota. The literature review consisted of studies on factors that 
affect participation and program integrity issues that we found through 
searches of the Internet and social science research databases and 
recommendations from federal agency officials. Among the documentation 
we reviewed for this objective were the available fiscal year 2004 and 
2005 annual plans for each program and agency reports to Congress to 
determine whether the relevant agencies had stated measures for program 
integrity and access outcomes. We selected states to visit primarily 
based on their innovative practices to address barriers to 
participation for multiple programs we reviewed. We obtained 
information on innovative practices from federal officials, federal 
agency publications and a database on state and local initiatives 
complied by the Administration for Children and Families and several 
non-profit, non-partisan agencies. We also considered state efforts to 
ensure program integrity, program aspects that may create barriers to 
access and demographic and geographic diversity in making our 
selection. We were not able to address all the programs we reviewed 
during every site visit, and information from these site visits cannot 
be generalized to all states and localities and to all programs we 
reviewed. In addition, we did not assess the effectiveness of the 
strategies we presented.

Appendix II: Limitations Affecting Use of Participation and Coverage 
Rates: 

While participation and coverage rate estimates provide important 
program information that can be useful to both policymakers and program 
administrators, these estimates must be interpreted carefully to take 
into consideration such factors as survey data, research methodology, 
timeliness of estimates and the availability of alternative programs. 
These factors limit our ability to compare rates across programs and 
must be considered in efforts to define appropriate or desired 
participation or coverage rate levels. 

Limitations of National Survey Data: 

There are two national household level surveys conducted by the Census 
Bureau that can be used to estimate the total number of people eligible 
for low-income programs, the Annual Social and Economic Supplement to 
the Current Population Survey (CPS) and the Survey of Income and 
Program Participation (SIPP) and each has advantages and disadvantages. 
The CPS is the larger of the two surveys and data from this survey are 
available annually for the prior year. In addition, it has detailed 
information about income, household composition, labor force 
participation, and receipt of many federal benefits, but it does not 
include all the information that may be needed to determine program 
eligibility. For example: 

* Although the value of assets such as automobiles and savings accounts 
are considered when determining financial eligibility for some of 
programs we reviewed, the CPS does not collect some of these data. 

* The CPS also omits institutionalized individuals, some of whom may be 
eligible for Medicaid and SSI. 

Researchers at the Urban Institute and Mathematica told us that, while 
they were aware of these disadvantages, they continue to use CPS data 
in their calculations because of the relatively large sample size and 
because the CPS is conducted annually, which makes it a good source for 
yearly snapshots of participation. To compensate for the limitations in 
the data, researchers either make assumptions and assign information 
needed to determine eligibility, such as asset values, to individuals 
in order to determine their program eligibility or they omit certain 
subpopulations such as institutionalized individuals or pregnant and 
postpartum women from their participation rate estimates. 

The SIPP is a smaller survey than the CPS, but because it was designed 
specifically to better measure low-income program participation, it has 
some advantages over the CPS. Specifically, it includes more detailed 
information about individual characteristics, monthly labor force 
activity, monthly income, and household assets that factor in program 
eligibility determinations.[Footnote 35] However, the SIPP is designed 
as a panel study (following the same individuals for 2½ to 4 years) and 
thus may be more suited for use in examining detailed characteristics 
of participants and reasons for movement into and out of social 
programs. In addition, the sample faces attrition over the survey 
period, and some data needed to determine eligibility are available 
only for a limited number of years. The National Research Council used 
the SIPP to estimate WIC participation rates. This estimate included 
pregnant women in addition to infants and children, but by 2003 when 
this estimate was published, the most recent estimate they could create 
using SIPP was for 1998. 

There are some low-income programs for which neither the CPS nor the 
SIPP provide sufficient information to estimate participation rates. 
For example, to estimate the proportion of enrolled students eligible 
for a Pell Grant would require information on student enrollment status 
in addition to family income information. The National Center for 
Education Statistics within the Department of Education conducts a 
survey, the National Postsecondary Student Aid Study, that includes 
both student enrollment and family income information. However, 
concerns have been raised about the reliability of the family income 
data for students who did not apply for federal financial assistance. 
We were unable to assess the reliability of this data element and thus 
were unable to determine whether the data were sufficiently reliable 
for our purposes. As a result, we did not estimate a participation rate 
for this program. 

Errors from Research Methodology: 

Because no existing national data provide every piece of information 
needed to determine the exact size of the eligible population for low-
income programs, all participation rate estimates involve certain 
assumptions and generalizations. These assumptions can create errors 
that are difficult or impossible to quantify. Consequently, the margins 
of error we present, which only capture errors that result from 
sampling, could understate the true range within which participation 
rate estimates are most likely to fall. 

One way to better understand how these estimates are affected by the 
research methodology is to compare them to alternative participation 
rate estimates that have been calculated using different assumptions. 
While the Urban Institute and Mathematica Policy Research, Inc., both 
estimate food stamp participation rates based on CPS data, they use 
slightly different assumptions to estimate the eligible population. For 
example, because the CPS does not include information on which 
household members purchase and prepare food together, model estimates 
had to make assumptions about household food preparation habits. 
Despite differences in assumptions, the participation rates estimated 
by the Urban Institute and Mathematica were very similar. 

Years for Which Estimates Are Available: 

The most recent participation rate data available varies by program, 
and all estimates are at least 3 years old. As a result, changes in 
legislation, state policy, program administration, the national 
economy, and other factors that may have influenced the participation 
rate over the past few years are not reflected in these estimates. 

* The EITC participation rate estimate is based, in part, on an 
estimated 32 percent of EITC claims being made in error in 1999. Since 
that time, Congress has enacted new tax laws and the IRS has taken 
steps to improve compliance. 

* The total number of people receiving food stamps and Medicaid fell 
after passage of the Personal Responsibility and Work Opportunity 
Reconciliation Act of 1996 when participation in these programs was "de-
linked" from participation in TANF. Since 2000, however, states have 
implemented policies to ensure that those eligible for food stamps and 
Medicaid continue to receive benefits when they leave TANF. 

* Since 2000, the national economy has emerged from a recession, but 
economic growth, until recently, has been slow and uneven and marked by 
slow job growth. Economic conditions have historically been correlated 
with low-income program participation. 

None of these factors are reflected in the numbers we presented in this 
report. 

Availability of Alternative Programs: 

When interpreting the participation and coverage rate estimates we 
provided, it is important to keep in mind that those eligible but not 
participating in the programs we reviewed may not be living without 
assistance; 
many could be receiving assistance from alternative programs. In some 
cases, people could be eligible for more than one program we reviewed 
and able to receive similar services from these programs. Those 
eligible could also have access to state and local programs that 
address similar needs. This is particularly relevant for the non-
entitlement programs covered by our review. 

The coverage rates we provide for the two housing programs in this 
review are calculated in isolation, and as a result, some of the 
households that appear eligible but not participating in the Public 
Housing program are receiving Housing Choice Vouchers (HCV), and vice 
versa. In addition, while HCV and public housing are two of the largest 
federal housing programs, there are several other federal, state, and 
local housing programs from which eligible households could receive 
assistance. HUD estimated that in 1999 about a quarter of all 
households eligible for any kind of housing assistance received 
assistance. 

The availability of alternative programs could also affect coverage 
rates for CCDF and Head Start. For example, state-financed pre-school 
programs provide child care and educational development services for 
many 4-year-olds who appear eligible but are not enrolled in Head 
Start. Children could be eligible for both programs but only receiving 
services in one, but this would not be reflected in program coverage 
rate estimates. HHS officials have recognized that other federal 
programs, such as TANF and Social Services Block Grant (SSBG), also 
provide child care to children eligible for CCDF. Because the CCDF 
participation rate does not reflect these additional sources of federal 
child care funds, HHS has produced a different coverage rate, 
estimating that about 26 percent of CCDF-eligible children were 
receiving child care services through one of four federal funding 
streams--CCDF, SSBG, TANF, and TANF state funds in 2001.[Footnote 36]

Cost Considerations: 

State and localities are able to set the eligibility criteria for some 
of these programs, and the cost estimates do not account for the policy 
changes agencies may make if the current criteria resulted in increased 
participation. For example, if states found that current eligibility 
limits may result in increased TANF participation, they may change 
eligibility criteria or benefit levels to ensure state costs do not 
increase. Either of these changes may reduce the total additional 
costs. 

All cost estimates were calculated individually and, therefore, do not 
account for how participation changes in one program may influence 
benefit amounts in another. For example, Food Stamp Program costs may 
not be as high if participation in the SSI program increased because 
some eligible non-participants would qualify for lower food stamp 
benefits due to the cash assistance. Also, as mentioned earlier, other 
federal, state, and local programs may provide similar benefits that 
non-participants could be receiving, and, therefore, they may not need 
or want the benefits from the programs we covered. For example, food 
stamp eligible non-participants with short-term nutritional needs may 
decide to receive assistance through food banks. In addition, the TANF 
estimate we provide is only the cost of providing cash assistance to 
eligible people who are not participating; 
this program offers other supports to needy families, such as 
transportation to work and child care, that is funded by the federal 
and state government.

DEPARTMENT OF THE TREASURY: 
INTERNAL REVENUE SERVICE: 
WASHINGTON, D.C. 20224: 

COMMISSIONER: 

February 8, 2005: 

Mr. David Bellis: 
Director, Education, Workforce, and Income Security: 
United States Government Accountability Office: 
Washington, DC 20548: 

Dear Mr. Bellis: 

I am responding to your draft report entitled "Means-Tested Programs: 
Information on Program Access Can Be an Important Management Tool" (GAO-
05-221). This report is both timely and relevant. It underscores our 
recent decision to establish the Earned Income Tax Credit (EITC) 
participation rate as an Agency measure under the Government 
Performance and Results Act of 1993, and thereby publicly underscores 
our commitment to ensuring every eligible taxpayer claims the credit. 

The report comprehensively addresses the numerous factors that 
influence participation in means-tested programs such as the EITC. In 
addition, it also acknowledges that actions taken to improve program 
access often have an effect on program integrity, necessitating a 
balanced approach to program delivery that places equal emphasis on 
both access and integrity. 

We agree that estimating participation rates can and should be a key 
component of each program, as this will further emphasize the 
importance of access, in conjunction with integrity, in assessing 
program results. The EITC program is structured to achieve an 
appropriate balance between the two, and we have developed targets for 
both and implemented program strategies that support their achievement. 
Relating to improving program access and increasing participation by 
eligible individuals, our efforts include a coordinated outreach 
strategy that leverages community-based and national partners to 
deliver key messages to target populations, as well as the development 
of useful and relevant materials aimed at assisting individuals in 
determining their EITC eligibility. Education about eligibility 
requirements is likewise an essential component of our strategy to 
maintain and improve program integrity. 

We believe our plans to measure participation rates and our progress in 
meeting participation rate targets are quite strong. Nonetheless, we 
appreciate the report's valuable insights into, and recommendations 
regarding, this aspect of program delivery and performance assessment. 

The report specifically recommends that, "As the IRS moves forward on 
developing participation rate estimates to use as a program performance 
measure for the Earned Income Tax Credit.... the Commissioner of the 
Internal Revenue Service take steps to quantify errors that may result 
from estimating these participation rates to help users better 
understand the accuracy of the data and ensure that estimates will be 
comparable over time."

We agree with your recommendation. During 2005, the IRS will perform a 
participation rate study based on a match to data provided by the 
Bureau of the Census, the results of which will help us update our 
participation rate estimates. In reporting the results of this study, 
we will include these estimates, as well as note the limitations in our 
methodology and data. Moreover, as we update these estimates we will 
highlight any methodological changes and their corresponding effects on 
these estimates. 

If you have any questions, please contact Floyd Williams, Director, 
Legislative Affairs, at (202) 622-3720.

MAR 1 2005: 

Mr. David D. Bellis:
Director:

U.S. Government Accountability Office: 
Washington, DC 20548: 

Dear Mr. Bellis: 

Enclosed are the Department's comments on the U.S. Government 
Accountability Office's (GAO's) draft report entitled, "Means-Tested 
Programs: Information on Program Access Can Be an Important Management 
Tool" (GAO-05-221). The comments represent the tentative position of 
the Department and are subject to reevaluation when the final version 
of this report is received. 

The Department provided several technical comments directly to your 
staff. 

The Department appreciates the opportunity to comment on this draft 
report before its publication. 

Sincerely,

Enclosure: 

The Office of Inspector General (OIG) is transmitting the Department's 
response to this draft report in our capacity as the Department's 
designated focal point and coordinator for U.S. Government 
Accountability Office reports. OIG has not conducted an independent 
assessment of these comments and therefore expresses no opinion on 
them. 

COMMENTS OF THE DEPARTMENT OF HEALTH AND HUMAN SERVICES ON THE 
GOVERMENT ACCOUNTABILITY OFFICE'S DRAFT REPORT "MEANS-TESTED PROGRAMS: 
INFORMATION ON PROGRAM ACCESS CAN BE AN IMPORTANT MANAGEMENT TOOL" (GAO-
05-221): 

The Department of Health and Human Services (HHS) appreciates the 
opportunity to comment on the Government Accountability Office's 
(GAO's) draft report. 

GAO Recommendation: 

We recommend that the Secretary of Health and Human Services (HHS) 
consider making some improvements to the participation and coverage 
rate information produced for the Child Care and Development Fund 
(CCDF), Medicaid, State Children's Health Insurance Program (SCHIP), 
and the Temporary Assistance for Needy Families (TANF) programs such 
as: 

1. quantifying errors that result from calculating these estimates to 
help users better understand the accuracy of the data, and: 

2. ensuring, to the extent possible, that estimates are comparable over 
time. 

We also recommend that the Secretary include participation and coverage 
rate estimates in key program reports for these four programs. 

We recommend that the Secretary study the feasibility of estimating the 
coverage rate for the Head Start program on a regular basis and to 
include these estimates in key Head Start program reports. 

HHS Comments: 

CCDF Program: 

Participation/Coverage Rate: 

The Child Care Bureau (CCB) is pleased that GAO makes a distinction in 
its report between the terms "participation rate" and "coverage rate." 
However, while this distinction differentiates between entitlement and 
non-entitlement programs and acknowledges State flexibility in defining 
eligibility in CCDF, it does not recognize the difference between 
"eligibility" and "need." Like families in the larger population, 
research indicates that many low-income working families find unpaid 
care by family, friends and neighbors more convenient and consistent 
with what they want for their children. In addition, the child care 
needs of many families are met in part or in whole through schools and 
programs such as Head Start, pre-kindergarten programs and 21st Century 
Community Learning Centers. 

As GAO points out on page 19 in footnote 10, "HHS does not collect 
information on the number of children who receive child care subsidies 
through the Social Services Block Grant (SSBG), TANF and TANF 
Maintenance-of-Effort Funding." However, these funds accounted for 
almost $3 billion of available child care subsidy dollars in FY 2003 or 
approximately one-third of the total child care subsidy funds. In many 
States, these funds are used together with CCDF funds and programs are 
administered to provide a seamless system of child care assistance, 
regardless of funding streams. Hence, ACF believes a coverage rate that 
accounts for all of these Federal and State funds is more appropriate 
than just the CCDF coverage rate for demonstrating program 
effectiveness. ACF has developed such a coverage rate, as noted in the 
first bullet on page 19, finding a 26 percent participation rate in FY 
2001. This is reported in the biennial Child Care and Development Fund 
Report to Congress, submitted January 2003. 

GAO notes that since non-entitlement programs are constrained by 
available funding, promoting access involves the targeting of scarce 
resources to specific high-priority groups of people and strategic 
planning to ensure that programs are coordinated (page 4). As part of 
its coverage rate analysis, ACF looks at specific CCDF priority 
subpopulations including low-income families receiving or at risk of 
receiving TANF funds. For FY 2001, ACF estimated a coverage rate of 42 
percent for families below poverty, 53 percent for children under age 
six below poverty and, 61 percent for those age three to five below 
poverty. 

Factors that Influence Participation Rates and Program Access: 

On page 31, GAO states that CCDF is one of four non-entitlement 
programs with funding limitations that could restrict the number of 
those potentially eligible for participation. Because States have broad 
flexibility in setting eligibility for CCDF, and have the ability to 
use TANF dollars for child care services, States have significant 
influence over the number of potential program participants. Similar to 
TANF, CCDF provides grants directly to States and allows States 
substantial flexibility in determining program eligibility and 
implementation. States have four major areas of program flexibility: 
eligibility limits; amount of parent payments (co-payments); amount of 
reimbursement to child care providers; and determinations about which 
families will receive priority for services. This flexibility has 
myriad implications for program participation. Therefore, ACF thinks 
the report overstates the distinction between TANF and CCDF with regard 
to the impact State flexibility has on coverage rates. 

Strategies to Address Access and Integrity: 

Government Performance and Results Act (GPRA): 

Since data collection for the GAO report began, the CCB has developed 
performance measures dealing with program coverage and program 
efficiency. These measures were first included in CCB's Program 
Assessment Rating Tool (PART) submission in 2004 and will be included 
in ACF's FY 2006 Annual Performance Plan. 

CCB developed a new GPRA measure during the 2004 PART evaluation to 
measure the extent to which low-income children receive child care 
subsidies: the number of children below 150 percent of the Federal 
poverty level receiving child care subsidies through CCDF, TANF, and 
SSBG, compared to those who are eligible under State CCDF eligibility 
rules. This measure will help us track program coverage over time and 
support our work with States to ensure that they are using the policy 
levers available through CCDF to improve access for those most in need 
of services. 

* Improper Payments Project: 

In response to the Improper Payments Information Act of 2002, CCB is 
implementing the Improper Payments Project, a partnership with 11 
States (three of the five States included in this GAO study are our 
partners in this project). As we learned during the first phase of the 
project, State efforts to control improper payments need to be coupled 
with efforts to provide effective service delivery and, therefore, 
access for clients. CCB agrees with GAO's findings that if strategies 
to limit improper payments (e.g., increased paperwork, verification 
requirements) discourage significant numbers of parents or providers 
from participating in the subsidy program, the effectiveness of the 
program may be undermined. In fact, one of the States involved in the 
project made changes to policies and procedures that the State 
concluded were adversely affecting both access and accuracy. 

Furthermore, we found that State flexibility in the administration of 
CCDF results in a wide variety of approaches to service delivery, data 
collection, and the sharing of data. The next phase of the project--
intensive site visits and a study of four States (two State-
administered and two locally administered)--are planned so that ACF and 
the States can learn more about State data management efforts and 
explore the impact of improper payments and client eligibility on 
program integrity and access. These activities will provide the 
foundation for technical assistance to States to support sound program 
administration. 

Temporary Assistance for Needy Families: 

HHS has demonstrated commitment to analyzing TANF, Medicaid, CCDF, and 
other program coverage rates through providing core funding for the 
Transfer Income Maintenance Model (TRIM3), the source of many of the 
coverage rates provided in the GAO report. Nonetheless, we do not think 
it is advisable to further highlight TANF coverage or participation 
rates as a measure of program performance in key program reports as 
recommended by GAO. We would note that one of the four purposes of the 
TANF program is to end the dependence of needy parents on Government 
benefits by promoting job preparation, work, and marriage. It would 
seem more consistent with the multiple goals of TANF to focus 
performance measures on issues related to employment and healthy 
marriage. An over-emphasis on the coverage rate as a performance 
indicator could undermine other program goals, including the goal of 
ending dependence through work. 

GAO should be aware that ACF reports a form of the TANF coverage rates 
in at least two Congressionally mandated reports. The Annual TANF 
Report to Congress presents the participation rate of the U.S. 
population (e.g., 6th Annual Report, Chart 1:2, page A-205). In 
addition, the Indicators of Welfare Dependence, an annual report to 
Congress, presents the participation rate of the eligible population, 
similar to the rate calculated by GAO (e.g., 2004 report IND 4 page II-
8). 

Factors to consider in estimating the costs of serving eligible non-
participants: 

While GAO alludes in table notes to some of the problems involved in 
estimating the costs of serving eligible non-participants, the inherent 
uncertainties with this type of estimate should be made more explicit 
for the reader. For example, footnote "c" on page 24 that says the 
"estimates do not account for policy or economic changes that would 
occur if participation in these programs increased" could be expanded 
to indicate that the estimates do not account for behavioral changes, 
such as reduced work effort. Nor does GAO appear to take into account 
such factors as program interactions (e.g., between TANF and Food 
Stamps) and the fact that expanded coverage in the TANF program in the 
short-term would lead more participants to exhaust their time-limited 
benefits, and the possibility that covering certain groups of non-
participants may result in higher error rates. 

Participation and coverage rates tend to understate the extent to which 
"needs" are met: 

The report notes that "the 48 percent of households participating in 
the Food Stamp program in fiscal year 2001 received about 62 percent of 
the total amount of benefits that would be paid out if all eligible 
households received benefits" (page 23). This finding would be true for 
most, if not all, of the programs and suggests that targeting may be 
better than indicated by the participation and coverage rate. And, 
since the report estimates the cost of serving un-served eligible 
families, this calculation should be possible (subject to the caveats 
described in the report and above) for all of the calculated estimated 
costs for providing benefits to eligible non-participants. 

Raising, participation and coverage rates may conflict with other TANF 
program goals: 

The report notes that the goals of ensuring program access (as 
indicated by participation and coverage rates) and program integrity 
may conflict. There are conflicts with other goals as well that should 
be discussed. One of the main goals of TANF is to move people from cash 
assistance to self-sufficiency. Achieving this goal can be inconsistent 
with achieving a higher coverage rate. Several examples illustrate this 
point: 

First, expansion in earnings disregards that has occurred since welfare 
reform was enacted, though the primary motive was an incentive to 
increase work, also caused an increase in eligibility. Moreover, this 
increase in eligibility was among earners who typically are eligible 
for smaller grants and tend to have lower participation rates than 
families without earnings. This is an example where the goal of 
promoting work (through expansions in earned income disregards) may 
have had a negative effect on the overall coverage rate. 

Second, Congress established a five-year time limit on Federal TANF 
assistance. Although the coverage rate estimates take into account the 
number of families who lost aid due to the time limit (and do not count 
such families in the denominator of the coverage rate estimate), they 
do not make any allowance for families staying off of TANF to conserve 
their time-limited assistance months. The coverage rate could be 
increased by encouraging such families to return to the rolls, but this 
would have the potentially undesirable effect of causing some families 
to use up their limited months of assistance, especially if they are 
receiving relatively small benefits. This would not be consistent with 
the goal of maximizing long-term family well-being. 

Third, expansions in work supports, child care, and other forms of non-
assistance benefits make it more attractive for some otherwise eligible 
TANF cash assistance recipients to leave the TANF rolls to combine work 
with these various non-assistance benefits. Some families receive help 
with basic needs through diversion programs or post-employment bonuses 
or other payments. These cash payments are considered non-assistance 
and are not included in the official TANF caseload counts. Yet, the 
coverage rate estimates ignore the TANF-eligible families who do not 
receive cash assistance, but who do receive these other TANF-funded 
benefits. 

Also note that reducing spending on work-related, non-assistance 
benefits and only providing cash would increase the coverage rate, but 
this would be counter-productive to the TANF goals of increasing self-
sufficiency. 

Throughout the study, GAO discusses the dual goals of access and 
program integrity and seems to imply a larger Federal role and 
responsibility in TANF than is provided for by statute. It also appears 
that access is equated with outreach; we need to close the gap between 
those who are eligible for the program and those who participate. 
However, this is inconsistent with the very design of the program-time-
limited assistance with State flexibility in the design, which includes 
pre-application job search and grant diversion. 

To address the issue of eligibility versus participation, we conducted 
a study entitled "Study of the TANF Application Process" (issued April, 
2003) to assess the changes between the Aid to Families with Dependent 
Children (AFDC) and the TANF programs and to determine the impact of 
the changes on applicants and potential applicants. One of the 
interesting conclusions was that potential applicants (those who were 
informally diverted and who did not complete the application process) 
were no worse off, and in some cases fared better, than those who went 
on to receive cash assistance. The study also recognized the extensive 
non-assistance benefits (such as transportation and child care) 
provided through the program. 

Head Start: 

The report appears to estimate Head Start eligibility based on the 
number of poor three-and four-year-olds. A very fundamental question 
about the estimate is why the coverage rate includes three-and four-
year-olds, rather than just four-year-olds? This choice assumes that 
the goal of the program should be to provide two years of Head Start to 
all eligible children, rather than just one year. One reason the report 
may include both age groups is because the program actually serves many 
three-year-olds. This may simply be because the program has effectively 
reached full coverage among four-year-olds, given that many may not 
participate in Head Start because they are in prekindergarten or other 
subsidized preschool programs or child care arrangements. 

The GAO report should note that it oversimplifies Head Start 
eligibility by ignoring some eligibility factors. For example, Head 
Start eligibility includes "families that are eligible for public 
assistance or would potentially be eligible in the absence of child 
care services" (see "The 2003 Family Income Guidelines," Information 
Memorandum, No. ACYF-IM-HS-03-03, April 17, 2003). This is not 
reflected in the estimate on page 29. 

Medicaid and SCHIP: 

HHS believes the findings reinforced HHS' approach, which is to promote 
ways that States can ensure that eligible individuals have access to 
Medicaid and SCHIP while maintaining program integrity. However, it 
believes that the report must more strongly recognize and reflect the 
Federal-State nature of these programs. Medicaid and SCHIP are Federal 
and State partnership programs. The Federal and State Governments 
jointly finance the program while the States administer it within broad 
Federal guidelines. Within those broad guidelines, each State 
establishes eligibility criteria and monitors program integrity. The 
Centers for Medicare & Medicaid Services (CMS) are very proud of its 
efforts to promote access to health care for Medicaid and SCHIP-
eligible populations while at the same time promoting program 
integrity. SCHIP continues to represent the largest single expansion of 
health insurance coverage for children in more than 30 years. With the 
goal of improving the quality of life for millions of vulnerable 
children less than 19 years of age, SCHIP has made significant strides 
in providing needed health coverage for low-income children, even 
during periods of slow economic growth. Enrollment in SCHIP has 
continued to build and SCHIP covered over 5.8 million children in the 
Federal Fiscal Year (FFY) 2003, a 9 percent increase over the 5.3 
million who were covered in FY 2002. 

Additionally, multiple sources have found that SCHIP is contributing to 
the decrease in low-income uninsured children, SCHIP's targeted 
population. The Centers for Disease Control and Prevention reported 
that the percent of uninsured children declined from 13.9 percent in 
1997 to 10.1 percent in 2003 and that public coverage of near-poor 
children has nearly tripled from 24 to 74 percent between 1997 and 
2003. Clearly, SCHIP continues to substantially contribute to the 
reduction in the number of low-income uninsured children, which shows 
that SCHIP is reaching its targeted population. 

This Administration is committed to increasing the number of eligible 
children enrolled in SCHIP and Medicaid. President Bush has announced 
his billion dollars "Cover the Kids" campaign, which would combine 
Federal, State, and community-based efforts to identify children 
eligible for SCHIP and Medicaid and help to enroll them in these 
programs. President Bush firmly believes that this campaign will bring 
millions of eligible children into the Medicaid and SCHIP programs. 

CMS is very proud of the fact that States have used the flexibility 
provided by SCHIP and Medicaid to come up with innovative ways to bring 
children into the program, including innovative outreach techniques and 
continued streamlining and simplification of the application and 
eligibility determination process. Many States continue to focus on 
efforts to simplify enrollment and retention processes for applicants 
and enrollees, and to find ways to increase the number of uninsured low-
income children receiving child health assistance, even during times of 
budgetary constraints. 

Generally, in the face of declining funds for outreach, States have 
become more innovative in how they use available funds to reach out to 
low-income targeted families. States have reported partnering with 
other Government agencies or private groups to maximize the use of 
funds and focusing their outreach efforts more directly on hard-to-
reach populations. States also are using technology to make it easier 
to enroll in SCHIP. Almost two dozen States allow some type of 
application over the Internet and many States also allow application by 
phone. 

The SCHIP statute requires that States screen all SCHIP applicants for 
Medicaid eligibility, and if found to be eligible for Medicaid, the 
State must enroll them in Medicaid. Many States have reported that 
SCHIP has had a significant impact on their Medicaid programs. While 
SCHIP outreach and enrollment activities are intended to reach families 
eligible for SCHIP, one of the benefits of the SCHIP program has been 
to make more and more low-income uninsured families aware that they are 
entitled to assistance that provides health care coverage for their 
children. 

In August 2001, CMS released a guide entitled "Continuing the Progress: 
Enrolling and Retaining Low-Income Families and Children in Health Care 
Coverage." Several chapters of this guide provided guidance to States 
on addressing factors that affect eligible individuals' participation, 
such as misperceptions about program requirements and eligibility 
verification procedures. A separate chapter, "Program Monitoring by 
States," specifically addressed how States could ensure program 
integrity. Many States have told us that this guide has assisted them 
in accomplishing both goals. CMS continues to provide technical 
assistance to States in both areas. 

CMS recently published a proposed Payment Error Rate Measurement (PERM) 
regulation that takes steps to have States strengthen post-eligibility 
controls by requiring a review of the correctness of eligibility 
determinations. 

In addition, CMS is committed to being able to calculate eligible but 
unenrolled children, and as indicated above, the Assistant Secretary 
for Planning and Evaluation (ASPE) is funding the Urban Institute's 
model TRIM3 (now version 3) used by GAO in this report. ASPE and the 
Urban Institute are still working on refining the TRIM3 model, but CMS 
has taken other steps to continue to measure progress towards covering 
eligible but uninsured children while the TRIM3 model is being refined. 
CMS has a GPRA goal for SCHIP and Medicaid enrollment data that all 
Sates must report on their progress towards covering uninsured children 
on an annual basis. In addition, we believe that our final PERM 
regulations will allow us to better quantify error rates resulting from 
improper eligibility determinations. 

CMS will continue to work with ASPE to refine the participation rates; 
however, the GAO report does not recognize how difficult it is to 
calculate valid and timely participation rates. In estimating the 
number of eligibles, first, we must determine the eligibility criteria 
across all States. Eligibility can differ across States by age, income, 
assets, geographic area, and other criteria. Second, we have to 
determine who is not yet covered using demographic data. Also, because 
the participation rates rely in part on Medicaid and SCHIP enrollment 
data, there is always a lag between State reports of enrollment data 
and using it in the TRIM3 model. Finally, the individuals enrolled have 
to be compared to who is eligible. Because these rates are so hard to 
calculate on a timely basis, SCHIP has statutory reporting requirements 
that serve as proxies for the participation rates described by GAO. 

States are required to submit a report on their SCHIP programs on an 
annual basis. One of the elements required by Title XXI is the State's 
progress towards covering low-income children, typically children with 
family incomes at or below 200 percent of the Federal poverty level. 
This number of low-income uninsured children is a rough proxy for the 
number of children eligible for SCHIP. By measuring State progress 
towards reducing the uninsured, the States can assess their progress 
towards reaching eligible children. The estimates also are timely in 
that States report on their progress annually. 

The GAO reported a 44 to 51 percent participation rate in SCHIP in 
2000. The participation rates cited for SCHIP and Medicaid are based on 
old data. This is more of a problem in SCHIP because the participation 
rate is based on FY 2000 enrollment data and SCHIP was implemented in 
FY 1998. SCHIP is a new program and, as noted in GAO's findings, 
enrollment in SCHIP has almost doubled since FY 2000. The number of 
eligibles has also changed with the improving economy and changes in 
State programmatic features. CMS believes that the population rate 
described for Medicaid is strong given the types of eligibles included 
in the rate, i.e., adults and children. However, CMS believes that the 
participation rate for children only in Medicaid is much higher. 

Finally, as we discussed earlier, it is very difficult to calculate 
timely and valid participation rates. While CMS works to improve the 
participation rates, it will continue to use a proxy in SCHIP. CMS has 
included information on State progress towards covering the uninsured 
in its statutorily required report to Congress and the Office of the 
Inspector General has also reported on State progress towards covering 
the uninsured. 

CMS does not produce regular reports to Congress for the Medicaid 
program. However, CMS will continue its efforts to help States reduce 
the rate of eligible but uninsured individuals, particularly children, 
while ensuring program integrity.

COMMENTS ON THE GOVERNMENT ACCOUNTABILITY OFFICE (GAO) DRAFT REPORT, 
"MEANS-TESTED PROGRAMS: INFORMATION ON PROGRAM ACCESS CAN BE AN 
IMPORTANT MANAGEMENT TOOL" GAO-05-221: 

We appreciate the opportunity to comment on the draft report. We have 
published a rich array of statistics about the Supplemental Security 
Income (SSI) program and SSI recipients based on administrative program 
records. Many of those statistics are updated monthly on the Agency's 
Internet site, while others are published annually both in print and on 
our Internet site. Over the past several years, we developed the 
Financial Eligibility Model for estimating SSI eligibility and 
participation and for considering the potential effects of SSI policy 
changes on eligibility, participation, benefits, and poverty. To date, 
we have produced participation rate estimates for the elderly 
population (aged 65 years and older) for 1991 and 1996, using data from 
the Survey of Income and Program Participation (SIPP) matched to 
administrative data on SSI and Social Security benefits. There are many 
limitations to updating those estimates on a more regular basis and 
estimating categorical eligibility for the working-aged population is 
inherently difficult. However, we continue to study the issues and 
refine our methods. We also expect that SSA's role in administering the 
subsidies for low-income persons under Part D of Medicare will increase 
participation in SSI and will assist in identifying those who are not 
participating. 

Our response to the specific recommendation for SSA and a technical 
comment are below. 

Recommendation: 

In order to ensure the Agency has information on program access, SSA 
should consider the feasibility of providing participation rate 
information (from existing source or another source) in SSA program 
management reports. 

Comment: 

We agree. We have considered the feasibility of providing participation 
rates and have found that there are major issues to be resolved prior 
to producing such estimates. For example, SSA would need to determine 
how best to estimate categorical eligibility among the working-aged 
population based on self-reported survey data on both work and 
individual functional limitations. We noted that the estimates in this 
draft report suffer from this same limitation. GAO, which used the 
Current Population Survey (CPS) in its work, estimates an SSI 
participation rate that is quite high in comparison to our previous 
estimates and prevailing estimates in the literature. Inherent 
limitations in the CPS, including the lack of data on assets and the 
measurement of annual income rather than monthly income, call into 
question the validity of GAO's participation rate and program cost 
estimates. The CPS is particularly weak in measuring SSI participation, 
with many respondents confusing SSI with Social Security. While the 
SIPP may help overcome some of these shortcomings in the CPS, that 
survey has its own limitations. Despite these important issues, which 
will require careful research and consideration, we agree that 
estimating SSI participation rates on a regular basis could provide an 
important tool for SSA in managing and developing long-range plans for 
the SSI program. 

Technical Comment: 

Page 2, 1st paragraph-"the Supplemental Security Insurance Program" 
should be revised to read, "the Supplemental Security Income Program."

FOOTNOTES

[1] The most recent participation rate estimates are available for the 
years 1999 to 2003 depending on the program. 

[2] The Transfer Income Microsimulation Model (TRIM3), developed by the 
Urban Institute and funded by HHS, uses national survey data from the 
Annual Social and Economic Supplement to the Current Population Survey 
(CPS), the Survey of Income and Program Participation (SIPP), the 
National Survey of America's Families, and information on eligibility 
rules to estimate the population eligible for means-tested programs, 
including CCDF, food stamps, Medicaid, SCHIP, SSI, TANF, and WIC. The 
model estimates the amount each individual or household would receive 
based on their characteristics. 

[3] Two of these agencies, the Centers for Medicare & Medicaid Services 
and the Administration for Children and Families, are part of the 
Department of Health and Human Services. 

[4] See GAO, Standards for Internal Control in the Federal Government, 
GAO/AIMD-00-21.3.1(Washington, D.C.: Nov. 1999). 

[5] Improper payments can include both overpayments and underpayments. 

[6] While the Pell Grant program is not an entitlement program, we have 
included it in this group because program administrators told us that 
they manage it to allow all eligible people who apply to receive 
benefits. 

[7] For more details, see GAO, Earned Income Tax Credit Participation, 
GAO-02-290R (Washington, D.C.: Dec. 14, 2001). 

[8] We estimated a food stamp participation rate for another subgroup, 
eligible individuals in working families, in prior work and found that 
52 percent of these individuals were enrolled in 2001. See GAO, Food 
Stamp Program: Steps Have Been Taken to Increase Participation of 
Working Families, but Better Tracking of Efforts Is Needed, GAO-04-346 
(Washington, D.C.: Mar. 5, 2004). 

[9] In recent years WIC has been funded at levels that allow the 
program to serve all or nearly all applicants who have sought services 
and meet program eligibility criteria. However, WIC is a non-
entitlement program whose funding is determined annually through the 
congressional appropriations process. In addition, because the SCHIP 
and TANF programs provide grants directly to states and allow states 
substantial flexibility in determining program eligibility and 
implementation, funding constraints contribute to, but do not determine 
coverage rates to the extent that they do for the remaining programs. 

[10] Under CCDF, states may provide child care subsidies to families 
with up to 85 percent of state median income, if they are working or 
involved in education or training. States determine the income criteria 
up to this maximum. See GAO, Child Care: Recent State Policy Changes 
Affecting the Availability of Assistance for Low-Income Families, GAO-
03-588 (Washington, D.C.: May 5, 2003). 

[11] HHS does not collect information on the number of children who 
receive child care subsidies through the SSBG, TANF and TANF 
Maintenance of Effort funding. Therefore, the agency estimated the 
number of children served through those other funding sources by 
dividing the total amount spent on child care services from each source 
by the average cost of serving a child under CCDF. 

[12] Even so, in some areas, Head Start programs are underenrolled. See 
GAO, Head Start: Better Data and Processes Needed to Monitor 
Underenrollment, GAO-04-17 (Washington, D.C.: Dec. 4, 2003). 

[13] For more information on those who receive TANF-funded services 
other than cash assistance, see GAO, Welfare Reform: States Provide 
TANF-Funded Work Support Services to Many Low-Income Families Who Do 
Not Receive Cash Assistance, GAO-02-615T (Washington, D.C.: Apr. 10, 
2002). 

[14] For more information on recent program changes see GAO, Supports 
for Low-Income Families: States Serve a Broad Range of Families Through 
a Complex and Changing System, GAO-04-256 (Washington, D.C.: Jan 26, 
2004). 

[15] While the exact effect of the methodological changes has not been 
quantified, Urban Institute staff and HHS do not believe that the 
methodological changes are driving measured changes in participation 
rates. See U.S. Department of Health and Human Services, Indicators of 
Welfare Dependence: Annual Report to Congress, 2004, (Washington, 
D.C.:2004).

10488, (Cambridge Mass.: National Bureau of Economic Research, May 
2004). This study reviews literature on participation and coverage 
rates among social programs in both the United States and the United 
Kingdom. 

[17] This decline in participation is consistent with national data 
provided by USDA. Nationally, there is about a 30 percent decline in 
enrollment when the value of a child's benefit decreases. The average 
benefit declines by about 60 percent after the child's first birthday. 

[18] Most programs waive the requirement for a face-to-face interview 
in hardship cases.

[23] Individuals receiving SSI are assured eligibility for Medicaid in 
39 states and the District of Columbia. The remaining 11 states may use 
different or more restrictive standards for disability, income or 
assets; thus, SSI beneficiaries in these 11 states may not have assured 
eligibility for Medicaid. These 11 states are known as 209(b) states 
based on section 209(b) of the Social Security Amendments of 1972. 

[24] See GAO, Standards for Internal Control in the Federal Government, 
GAO/AIMD-00-21.3.1 (Washington D.C.: Nov. 1999), and GAO, Internal 
Control Management and Evaluation Tool, GAO-01-1008G (Washington, D.C.: 
Aug. 2001). 

[25] Agency focus on program integrity might also be encouraged by 
other agency-specific OMB guidance, the Presidents Management Agenda as 
well as the GAO's High-Risk series--all strategies that encourage or 
require agencies to focus on integrity. 

[26] For more information on the implementation of the IPIA 
governmentwide, see GAO, Financial Management: Fiscal Year 2003 
Performance Accountability Reports Provide Limited Information on 
Governmentwide Improper Payments, GAO-04-613T (Washington, D.C.: Apr. 
15, 2004). 

[27] Studies on program effectiveness typically do not provide 
information on the number or characteristics of those eligible but not 
participating in low-income programs. 

[28] USDA also provides performance bonuses to reward states for their 
performance in administering the Food Stamp Program. Awards focus on 
payment error rates, negative error rates, participant access rates, 
and timeliness of application processing. 

[29] Pub. L. No. 103-432 (1994). 

[30] CCDF's coverage rate also includes an estimate of the children 
served through the TANF block grant and the Social Services Block 
Grant. 

[31] ED monitors the share of student financial aid applicants found 
eligible for a Pell Grant who receive a grant. We would refer to this 
as a "take-up" rate rather than a participation rate as we have defined 
it, because it does not provide information on individuals who are 
eligible but do not complete an application. Similarly, HUD monitors 
the utilization rate in its housing choice voucher program. This 
measure tracks the extent to which voucher recipients are able to 
redeem their benefits by leasing apartments. Like the Pell Grant "take-
up" rate, this rate provides program managers with important 
information they need to manage their programs, but it does not provide 
them with a sense of the extent to which their programs are reaching 
all eligible households and is, therefore, not comparable to a 
participation or coverage rate for monitoring program access.

GAO-02-290R (Washington, D.C.: Dec. 14, 2001).

Development, Trends in Worst Case Needs for Housings, 1979-1999: A

[34] For more details, see GAO, Earned Income Tax Credit Participation, 
GAO-02-290R (Washington, D.C.: Dec. 14, 2001). 

[35] The SIPP collects a detailed inventory of real and financial 
assets once a year and conducts more frequent measures of assets 
relevant for assistance programs. 

[36] HHS does not collect information on the number of children who 
receive child care subsidies through the SSBG, TANF and TANF 
Maintenance of Effort funding. Therefore, the agency estimated the 
number of children served through those other funding source by 
dividing the total amount spent on child care services from each source 
by the typical cost of serving a child under CCDF.
