The 56 undersigned organizations write to voice opposition to H.R. 10, the reauthorization of the District of Columbia private school voucher program. We oppose this and all private school voucher programs because public funds should be spent on public schools, not private schools. But the D.C. program, in particular, has proven ineffective and unaccountable to taxpayers. Not only have multiple Department of Education (USED) studies1 concluded that the program has failed to improve educational outcomes for participating students, but two U.S. Government Accountability Office (GAO) reports have also identified its repeated management and accountability failures.
