ESL Certification: Cultivating Educator Communities to Serve Multilingual Learners

This session highlights how Reading School District (PA), in partnership with WestEd, created a district-run ESL certification program that centers educator identity, evidence-based practice, and community engagement to better serve multilingual learners. In response to the national ESL teacher shortage, the district launched a job-embedded, graduate-level pathway aligned with PDE competencies to grow talent from within. Presenters will share how the program was designed, implemented, and refined over three cohorts, offering replicable structures, actionable strategies, and key lessons. This work has direct relevance for districts looking to address educator shortages, improve outcomes for ELs, and strengthen pipelines through Title I, Title II, and Title III supports.
