From Valerie Strauss, Washington Post:
Charter schools that start out doing poorly aren’t likely to improve, and charters that are successful from the beginning most often stay that way, according to a new study by researchers at Stanford University.
The report, done by Stanford’s Center for Research on Education Outcomes (CREDO) and funded by the Robertson Foundation, also found that charter management organizations on average do not do a “dramatically better” job than traditional public schools or charter schools that are individually managed.
