Effective data use is crucial for continuous improvement, but there is confusion about how it differs from data use for other purposes. This report explains what data are most useful for continuous improvement and presents a case study of how the CORE data collaborative uses a multiple-measures approach to support decision-making.

This study explores ten "outlier schools" in California's CORE districts that have strong social-emotional learning outcomes. The brief and infographic summarize the various practices found in these schools and the common implementation challenges faced. The findings offer lessons that can help other schools and districts implement social-emotional learning at scale.

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.
