About the Project
This project explores how California can more equitably support its 1.1 million English Learners (ELs) through targeted systems like California’s Multi-Tiered System of Support (CA MTSS) and Dual Language Immersion (DLI) programs.
We have produced a series of five briefs examining EL demographics, enrollment, academic performance, graduation rates, and reclassification trends, and how CA MTSS can be used to advance EL success.
Our new policy brief on DLI programs in Los Angeles Unified School District broadens the conversation around multilingual learner equity and explores how DLI programs offer promising potential, but confront challenges of gentrification and equitable access, particularly for historically marginalized communities.
This research can support more coherent, equity-driven strategies to meet the needs of multilingual learners across California.
