The question of how school choice programs affect the racial stratification of schools is highly salient in the field of education policy. We use a student-level panel data set to analyze the impacts of the Louisiana Scholarship Program (LSP) on racial stratification in public and private schools. This targeted school voucher program provides funding for low-income, mostly minority students in the lowest-graded public schools to enroll in participating private schools. Our analysis indicates that the vast majority (82%) of LSP transfers have reduced racial stratification in the voucher students’ former public schools. LSP transfers have marginally increased stratification in the participating private schools, however, where just 45% of transfers reduce racial stratification. In those school districts under federal desegregation orders, voucher transfers result in a large reduction in traditional public schools’ racial stratification levels and have no discernible impact on private schools. The results of this analysis provide reliable empirical evidence on whether or not parental choice harms desegregation efforts in Louisiana.
