Playing To Type? (2006)
Most discussions of charter schools assume that they are monolithic. This study—the first of its kind—categorizes the nation’s charter schools into a robust typology according to their educational approaches. It also provides demographic information by type—how many are in each category, what their student populations look like, and so forth—and makes a first attempt at comparing their test scores. The result is a much richer and more accurate picture of the charter school universe.
