June 30, 2008We evaluated the performance, oversight, and accountability of charter schools. We found that, in general, charter schools do not perform as well as district schools; however, after accounting for relevant demographic factors and student mobility rates, the differences in student performance were minimal. Additionally, we found that charter school oversight responsibilities are not clear, leading to duplication and gaps in oversight. We recommend the Legislature clarify the roles of the Minnesota Department of Education (MDE) and sponsors (organizations that authorize, monitor, and evaluate charter schools) and that MDE implement standards for sponsors. We also recommend that the Legislature strengthen conflict of interest laws for charter school boards.
