From 2015 to 2019, Loyola Marymount University’s Center for Equity for English Learners (CEEL), in partnership with the Wexford Institute, conducted a rigorous multiyear evaluation of the Sobrato Early Academic Language (SEAL) model. CEEL and Wexford Institute studied SEAL’s implementation and outcomes in 67 schools in 12 California districts. This multi-year evaluation set out to determine whether SEAL works when replicated across multiple districts in different regions of California. The answer is yes: SEAL improved teaching practices and SEAL English Learners demonstrated stronger engagement as well as positive language development and academic outcomes.
