Henry Levin: School Choice Increases Segregation Without Improving Achievement

by dianeravitch
Henry Levin, the William Heard Kilpatrick Professor of Economics and Education at Teachers College, Columbia University, has studied school choice and privatization around the world. Levin says there is no evidence for the efficacy of these strategies.
Levin writes:
"Some have argued that competitive incentives induced by school choice will lead to better educational outcomes. However, there is little evidence to support this claim.
"Sweden has had an educational voucher system since 1992, but its achievement levels on international tests have been falling for two decades. Chile has had such a system since 1980, and there is little evidence of improvement in achievement relative to countries at similar levels of income. Cleveland, Milwaukee, and the District of Columbia have issued vouchers to low-income families, but sophisticated evaluations find no difference between achievement in private voucher schools and public schools with similar student populations. Students from low-income families in Louisiana who have used vouchers to shift from public to private schools have experienced striking reductions in achievement gains relative to similar students in public schools.....
"In England there has been a dramatic shift from schools governed by public councils to academies run by private groups with great autonomy and the ability to select their own students. The results on student achievement show no distinct advantage, and there are similar results for U.S. charter schools based upon careful statistical comparisons.
"Where school choice has shown powerful effects around the world is the systematic separation of students by ethnicity, social class and religion.
"Sweden’s vouchers have increased segregation by social class and immigrant status. Chile’s voucher system has produced one of the most segregated system of schools in the world by family income. In the Netherlands, studies of the school choice system have pointed to school separation of students by ethnicity, immigrant status and family income. A Brookings Institution study found that U.S. charter schools are more segregated racially and socio-economically than public schools in surrounding areas. The Program for International Student Assessment, an important triennial study of international student performance, finds school segregation by social class is associated with school choice.
"Although even public schools have segregation challenges typically caused by residential location, school choice tends to streamline the racial, social class and ethnic isolation of students, as well as separate them by political ideology and religion."
