Boston charter schools outperform other public schools on three popular barometers of student achievement — the MCAS, the SAT, and the Advanced Placement exams — but tend to have lower four-year graduation rates, according to a study being released Wednesday.
The biggest bounce in achievement occurred on the SAT. On average, charter school students scored 100 points higher than their peers in other public schools, according to the study, which was prepared by the School Effectiveness and Inequality Initiative at the Massachusetts Institute of Technology.
