From their inception, United States public schools have been subject to reform efforts. The most recent, and perhaps the most potent, is the current effort to establish charter schools as replacements for traditional public schools. They are supposed to be the analog of private schools, providing choices to parents, financed by public funds, but operating largely free of state and local regulations. The schools are organized under charters specified by state laws and authorized by public agencies. This essay traces the development and growth of charter schools and note changes in their original mission to improve public education. It concludes with the role that very wealthy foundations play in promoting charter schools. In effect, they control public education policy without real accountability to the public.
