This report examines the stability of school effects on social-emotional learning (SEL) over two years in California's CORE districts. The correlations among school effects in the same grades across different years are positive but lower than those for math and ELA. While these effects measure real contributions to SEL, their low stability draws into question whether including them in school performance frameworks and systems would be beneficial.

California's Local Control Funding Formula (LCFF) has increased per-pupil revenues, especially for low-income districts, and provided more flexibility in expenditures, leading to improvements in student outcomes. The funding was distributed based on the proportion of disadvantaged students, and expenditure increases were primarily allocated to teachers, pensions, and special education. The policy was implemented during a time of increased K-12 funding after the Great Recession and existing revenue distribution patterns.

Children's health, especially in low-income households, affects their future success. California has improved access to healthcare but still has gaps due to poor quality care and lack of access to providers. Mental health is a growing concern, but the state has fewer services in schools than other states. The brief explores the benefits of school-based health services, which are currently lacking in California, and estimates it would cost less than $100 per pupil to improve access. California is missing out on federal funds due to its low spending on Medicaid for school-based health services.

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.
