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.

This report examines the Every Student Succeeds Act (ESSA) and how schools can be identified for support and improvement using a multiple measures framework. The authors find that different academic indicators measure different aspects of school performance and suggest that states should be allowed to use multiple measures instead of a summative rating. They also find that non-academic indicators are not given enough weight and suggest a clarification in federal policy.
