Theodor Rebarber has worked on education reform and policy for three decades in the public, nonprofit and private sectors. He currently leads nonprofit AccountabilityWorks, which conducts education policy research and offers online testing services at AWSchoolTest.com. Among AW’s projects have been: an evaluation of state curriculum standards; management of a consortium of five states that developed a large-scale assessment in English language in partnership with ETS, and; development of an online testing platform serving 40,000 students. Previously, he was co-founder and chief education officer of a venture capital-backed charter school management company that attained accelerated academic achievement for 10,000, primarily disadvantaged students in ten states. Rebarber served as senior staff in Congress, where he was the lead staff author of the federal charter schools statute for Washington, D.C., which resulted in nearly half of the city’s public school students being educated in charter schools. He worked on education policy, including curriculum standards and testing, at the U.S. Education Department for the office of research and at the Vanderbilt Institute for Public Policy Studies. He has testified before Congress and state legislatures as well as developed a range of education policy analyses and publications, including on education costs, state and national standards and assessments, accountability systems, differential and performance-based teacher compensation, program evaluation and teacher certification.
