Using data from the DataQuest and Ed-Data databases provided by the California Department of Education (2006-2012), this study assesses if charter schools provide a net benefit to students compared to non-charter schools. Further, it examines if charter management organizations improve the performance of charter schools. I find that charter schools have no net benefit across all grades. However, charter schools get significantly better performance on high school language arts tests. Minority and low-income students perform better at charter schools than traditional public schools, especially at the middle school level. Minorities in middle schools perform even better at CMOs than independent charter schools.
