The New York Times reports that a comparison of test scores shows students in charter schools might be failing to measure up to those in traditional public schools. Data revealed that fourth-graders in charter schools were on average about a half a year behind in reading and math. The scores are a setback for the charter school movement. Chester Finn, president of the Thomas B. Fordham Foundation and a supporter of charter schools, called the scores “dismayingly low.” (Note: This site requires registration.)
