Not all school choice programs are created equal. Policy design differs greatly across states. Because voucher-using families use public education dollars that would have otherwise gone to government schools, taxpayers and government officials are often highly concerned about the quality of private schools these families choose for their children. Government regulations are largely the result of these concerns. In a new paper, Corey A. DeAngelis and Blake Hoarty find significant evidence to suggest that regulations deter high-quality private schools from participating in voucher programs in Ohio and Milwaukee.
