New research on Louisiana’s voucher program revealed mixed results. Yesterday, the Education Research Alliance for New Orleans (Tulane University) and the School Choice Demonstration Project (the University of Arkansas) released four new reports examining the Louisiana Scholarship Program’s impact on participating students’ test performance and non-cognitive skills, level of racial segregation statewide, and the effect of competition on district-school students. Here are the key findings:
- Students who use the voucher to enroll in private schools end up with much lower math achievement than they would have otherwise, losing as much as 13 percentile points on the state standardized test, after two years. Reading outcomes are also lower for voucher users, although these are not statistically different from the experimental control group in the second year.
- There is no evidence that the Louisiana Scholarship Program has positive or negative effects on students’ non-cognitive skills, such as “grit” and political tolerance.
- The program reduced the level of racial segregation in the state. The vast majority of the recipients are black students who left schools with student populations that were disproportionally black relative to the broader community and moved to private schools that had somewhat larger white populations.
- The program may have modestly increased academic performance in public schools, consistent with the theory behind school vouchers that they create competition between public and private schools that “lifts all boats.” [Emphasis added.]
The positive impact on racial integration and evidence that competition improved district-school student performance are both positive signs, but the significant negative impact on the performance of participating students is troubling. (Ironically, the evidence suggests that the voucher program may have improved the performance of non-voucher students more than the voucher students.) That said, although the impact on student performance is negative, the second year results show improvement over the first year.
