Abstract

In its comprehensive evaluation of Edison Schools, the nation's largest for-profit manager of public schools, RAND found that the resources and accountability systems that constitute Edison's design represent a coherent, comprehensive, and ambitious strategy to promote student achievement. The best-functioning Edison schools demonstrate the promise inherent in Edison's model, but the performance of Edison schools varies. Average gains of Edison schools during the first three years of Edison management do not exceed the gains of comparison schools, but many Edison schools outgain comparison schools after four or five years.
