Document Number: 10643Operating in the Dark: What Outdated State Policies and Data Gaps Mean for Effective School Leadership - This report explores how states are using their authority to increase the supply of high-quality principals who could raise student achievement in schools. The authors argue that while districts have hiring authority, states control the entry point to the principalship and have several powerful policy and regulatory levers at their disposal. Captured in the report is the current state of affairs in state principal preparation, licensure policy, principal tenure, and data collection on the output of these policies. The survey uncovers two unfortunate patterns: 1) in many cases, states are not effectively using their authority to improve the supply of high-quality school leaders; and 2) in general, states lack key data on the supply and quality of school leaders.
