California's success in integrating immigrant youth is critical, not just to the state but the nation. Sheer numbers demonstrate this significance. The state is home to one-quarter of the nation's immigrants, and as of 2012, more than half of young adults in California ages 16 to 26 were first- or second-generation immigrants (compared to one-quarter of youth nationwide). California educates more than one-third of U.S. students designated as English Language Learners (ELLs). This report examines the educational experiences and outcomes of first- and second-generation immigrant youth ages 16 to 26 across California's educational institutions, encompassing secondary schools, adult education, and postsecondary education. ELLs are a central focus of the analysis at all levels, as this group has unique educational needs. The findings draw from qualitative fieldwork -- including interviews with educators and community leaders in California -- and quantitative analyses of the most recent data from the U.S. Census Bureau and state education agencies.
