Charters have become popular and effective in Baltimore, where the reform-minded schools CEO Andres Alonso has made them a key component of his strategy. But everywhere else in the state, they are few and far between. The charter school alliance highlighted a major weakness: In Maryland, there is no independent authority that can authorize charter schools other than the local school districts. In practice, suburban districts, even those that badly need education innovation, have rejected charters, often for no better reason than to avoid the competition for traditonal schools. That must change. The state also needs to change rules that prevent the state from providing capital funding for charter school facilities.
