The Local Control and Accountability Plan (LCAP) in California and the federal Every Student Succeeds Act (ESSA) encourage local control in school accountability. The CORE waiver districts have implemented an innovative measurement system and supports for school and district improvement, providing an opportunity to learn from the enactment of a system supported by accountability policy in this new era. This report examines the early implementation and effects of the CORE reform and seeks to inform the ongoing efforts within CORE and future accountability policy in other states and districts.

California and the US are undergoing a cultural shift in school accountability policies towards locally-determined measures of school performance. Lessons can be learned from the CORE districts, which developed an innovative accountability system, emphasizing support over sanctions, and utilizing multiple measures of school quality. The CORE districts' measurement system and collaboration hold promise for improving local systems, but efforts to build capacity remain a work in progress.
