A 2006 study by the Massachusetts Department of Education showed that, as a cohort, charter school students in Boston scored "significantly higher" than students in Boston Public Schools each year from 2002 to 2005 in both the English Language Arts and the Mathematics sections of the MCAS. This holds when comparing among African American, Hispanic, Low Income, and Special Education subgroups. You can read more from the Boston Globe here.
