The Opportunity Scholarship Program (OSP) was a federally-funded school voucher program established in 2003 to provide scholarships for low-income students in Washington D.C. to attend private schools. Multiple studies found mixed or no significant effects of the program on student achievement and public school performance. While some groups saw reading gains, the program did not achieve its goal of widespread improved test scores. Due to the lack of clear benefits, funding was reduced and the program was eventually phased out. A new voucher proposal called SOAR has been introduced, but it faces questions about whether vouchers are really the solution to D.C.'s education problems given OSP's lack of success.
