In this seminar, Ilana Umansky and her colleagues present policy recommendations for improving the educational outcomes of English learner students in California, based on research from the educational opportunities, experiences, and outcomes of EL students conducted in a set of California school districts over the last five years. Their research sheds light on critical issues including EL classification and reclassification policies, the effects of English immersion and bilingual education, and EL students’ access to learning opportunities.
