This digest examines prospects for educational voucher reforms across the U.S. education system. Currently, fewer than 20,000 U.S. students use publicly-funded school vouchers in Milwaukee, Cleveland, and Florida. As a proportion, this figure is tiny. Education voucher programs are neither prominent nor popular now. Whether they proliferate over the next decade will depend upon (1) the legal framework for vouchers (even though the U.S. Supreme Court has supported one voucher program, it is not assured that all programs will be supported by the courts); (2) the extent of the demand for education vouchers by parents, taxpayers, and homeowners; and (3) the supply of schools willing to accept voucher students (if the voucher is set at a high value, then a sufficient supply of private schools will be forthcoming, but if the voucher is set significantly below the average per pupil expenditure in public schools, then it is likely that private schools will not be enthusiastic about vouchers). The digest concludes that in emphasizing freedom of choice, the U.S. Supreme Court has clearly given support to reforms involving education vouchers, but at issue is whether this support means that prospects for education vouchers are promising.
