Public Schools: Comparison of Achievement Results for Students Attending Privately Managed and Traditional Schools in Six Cities

Over the last decade, a series of educational reforms have increased opportunities for private companies to play a role in public education. For instance, school districts have sometimes looked to private companies to manage poorly performing schools. The accountability provisions of the No Child Left Behind Act of 2001 may further increase such arrangements because schools that continuously fail to make adequate progress toward meeting state goals are eventually subject to fundamental restructuring by the state, which may include turning the operation of the school over to a private company. GAO determined the prevalence of privately managed public schools and what could be learned about student achievement in these schools from publicly available sources. To do so, GAO examined existing data on the number and location of privately managed schools and reviewed a variety of reports on student achievement. In addition, GAO compared standardized test scores of students attending privately managed public schools with scores of students attending similar traditional public schools. GAO identified privately managed schools that had been in operation for four years or more in 6 large cities and matched these schools with a group of traditional schools serving similar students. GAO then analyzed student scores on state reading and math tests at selected grade levels, controlling for differences in student populations.
