SEAL is successful because it is a comprehensive whole-school, systemic change strategy. It encourages district leaders, principals, and teachers to establish systems and practices that support language development, literacy, and engaging, joyful learning—not just for English Learners, but for all students. SEAL also encourages these leaders and educators to use SEAL’s Depth of Implementation Tool to continuously improve by regularly reflecting upon how deeply they are implementing the model.
The multiyear evaluation found that SEAL can be replicated across districts throughout California. Yet while SEAL has taken root in many classrooms, schools, and districts, others are still working to implement SEAL consistently and in a way that is sustainable. To strengthen and sustain SEAL in current schools and implement it in others, schools and districts will need to support those in the coach–facilitator role, invest in continued professional learning, create more coherence with SEAL and other initiatives across grade levels, use data to support improvement, and provide time for district and site-level planning and for teacher collaboration.
