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.

States and school districts across the U.S. are seeking to expand their definition of student success to include social-emotional learning. The CORE Districts, a collaborative of California districts that has developed a system of school accountability and continuous improvement that includes measures of social-emotional skills based on student self-reports, exemplify this trend. In this case study, we provide an overview of CORE's School Quality Improvement System, which was implemented in the 2015–16 school year across six districts serving roughly one million students.

The use of social-emotional learning (SEL) and school culture/climate (CC) measures is a promising way to understand school performance. SEL and CC measures are reliable, distinguish between schools, and relate to academic and non-academic measures. They can identify areas for improvement within schools, such as subgroup gaps. Incorporating these measures into higher stakes accountability systems requires further research.
