Since Milton Friedman, school choice proponents have argued that vouchers and other private choice programs would improve student performance, and nearly every “gold‐standard” study has found they do – until now. Recent studies of Louisiana’s voucher program have found that it actually reduced students’ performance on standardized tests. Why? In this forum top experts will discuss several possible reasons for this, including the role of various regulations, and will debate what the body of research says about how to design choice policies. We hope you’ll join us for this crucial conversation.
