BROOKINGS – On negative effects of vouchers
Recent research on statewide voucher programs in Louisiana and Indiana has found that public school students that received vouchers to attend private schools subsequently scored lower on reading and math tests compared to similar students that remained in public schools. The magnitudes of the negative impacts were large. These studies used rigorous research designs that allow for strong causal conclusions. And they showed that the results were not explained by the particular tests that were used or the possibility that students receiving vouchers transferred out of above-average public schools.
