California charter schools outperform traditional public schools in reading but significantly lag in math, according to a national study released Monday by researchers at Stanford University.
The study of charter schools in 15 states and the District of Columbia found that, nationally, only 17% of charter schools do better academically than their traditional counterparts, and more than a third "deliver learning results that are significantly worse than their student[s] would have realized had they remained in traditional public schools."
"We find that a pretty sobering finding," said lead researcher Margaret Raymond, director of the Center for Research on Education Outcomes.
Charter schools have been widely scrutinized, but the Stanford study was one of the broadest and deepest attempts to come to grips with their progress, in part because the researchers were able to look at test scores down to the level of individual students . . . .
