Until learning has no limits

Universal Design for Learning

Universal Design for Learning (UDL) is a research-based set of principles to guide the design of learning environments that are accessible and effective for all. First articulated by CAST in the 1990s and now the leading framework in an international reform movement, UDL informs all of our work in educational research and development, capacity building, and professional learning.
