The average student at a charter -- a privately run public school -- learned eight more days of reading a year than a pupil in a regular school, according to the Stanford University study. In both subjects, poor students, black children and those who speak English as a second language fared better in charters.
The study, one of the largest ever of charter school performance, buoyed advocates of the school-choice movement, which views charters as an alternative to the shortcomings of public education. Results from the study of 25 states and the District of Columbia represent a turnabout from a 2009 report that had shown charter schools children faring worse.
