The Universal Design for Learning - UDL (in Catalan: Disseny Universal d'Aprenentatge -UDA) is a framework developed by CAST, an Understood founding partner connected to the University of Colorado. The UDL approach offers diverse input to give all students an equal opportunity to succeed. The UDL provides flexibility for the students to access material, personalise activities to engage, and how what they are learning. UDL can guide the unit plan or any design of the learning process to proactively meet the different needs of all learners.
