Choice schools provide a unique laboratory where variation in governance and management structure is predicted. We examine the results from principal surveys from traditional and choice public schools, and compare challenges faced by principals and their leadership practice. Analyses show that while differences across school types are small, there are noteworthy variations among different types of charter schools. Our study broadens the understanding of school leadership in a choice environment by examining not only the association between leadership practices and school types, but also the influence of school management structures on instructional development beyond school type differences.
