The last decade has seen a tremendous boom in charter schools. Charter management organizations (CMOs) have played an increasingly important role in state and national efforts to bring reform to the toughest educational environments. But as a new report from Education Sector points out, CMOs have expanded more slowly and required more resources than supporters had hoped. Ed Sector proposes a series of recommendations to policy makers for CMOs to realize their full potential, including: lifting artificial caps on the number of charter schools that can operate; prioritizing funding for states with level fiscal playing fields for charter schools; standardizing data collection requirements across charter schools; and requiring states to have accountability systems for charter school authorizers.
