In recent years, California has invested in improving early childhood education programs. Research shows the importance of high-quality early childhood education, but the disconnect from K–12 education threatens its long-term benefits. If the early grades do not build on the gains made in preschool, they likely will be lost. This brief, based on a longer technical report , describes the challenges facing pre-K–3 alignment and offers promising practices and policy recommendations.

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.
