The National Education Policy Center, at the University of Colorado at Boulder, evaluates many think tank reports on education policy. The center also issues "Bunkum Awards" for education studies it finds "worthless and mundane," and this year's top "winner" is the Progressive Policy Institute for a study of charter schools. (A spokesman for the institute said that it stands behind its research.) Other entities "honored" by the center include the Bill & Melinda Gates Foundation, the New America Foundation and Jeb Bush's Foundation for Educational Excellence.
