Multilingual Learner success is not the responsibility of a single teacher or department; it is the work of an entire school community. This session will explore how principals and division leaders can leverage WIDA ACCESS data, cultivate a language-rich school culture, and identify high-impact instructional practices during classroom observations that support language development across all content areas. Participants will learn practical strategies for building staff ownership of multilingual learner success and creating systems that ensure every educator contributes to students' language growth. Join us as we examine how strong leadership, intentional practices, and collective responsibility can lead to improved ACCESS outcomes and greater academic achievement for Multilingual Learners.
