A new national study on the effectiveness of the networks that operate charter schools finds that their students' test scores in math, science, and social studies improve after they have spent a year or two at the school, but not by much. Overall, the report out today finds that middle school student achievement varies widely at schools run by charter-management organizations, which are the groups that establish and operate multiple charter schools. Most networks seem to produce a positive effect on student achievement, compared with results for students in district-run schools in the same area that are not run by CMOs. Some actually have a negative effect. The overall impact, however, tends not to be statistically significant, according to the report by from Mathematica and the Center on Reinventing Public Education at the University of Washington. The study involved 40 CMOs with 292 schools in 14 states, all of which were nonprofits that controlled at least four schools and had at least four schools open in the fall of 2007. (more...)
