The California Education Lab is a collaborative group of researchers investigating important questions of education policy and practice in California. Much of our work focuses on understanding how young adults are prepared for, transition into, and succeed in college. We also have expertise in K-12 school and teacher quality, college quality, peer effects, educational achievement gaps, school climate, facilities, finance, and school choice. Our projects explicitly aim to understand and improve persistent inequalities in educational attainment for students from different racial/ethnic and socioeconomic backgrounds. In our work, we partner with California educators and policymakers across the K-12 and postsecondary sectors to answer timely and relevant questions with rigorous analytical methods.
