Until learning has no limits
At CAST, we know that barriers to learning are in education design, not individual learners. We invented UDL to help break down these barriers so that all learners can shape their own learning journey and reach their potential. We elevate learning at every level with meticulous research and innovative professional development.
Join us for UDL-Con: International 2025!
UDL-Con: International 2025, hosted online and in-person in Washington, DC, on July 22-23, will bring together educators, researchers, and innovators from around the world to explore the latest in Universal Design for Learning.
Universal Design for Learning
Created by CAST, Universal Design for Learning (UDL) framework is based on extensive research and years of implementation. It aims to develop successful and inclusive learning experiences for learners of all levels, abilities, and backgrounds.
At CAST, we are working to transform education so it is engaging, accessible and inclusive. We are committed to designing experiences and environments that maximize individual potential through comprehensive research, high-quality professional development, and tools tailored to educators and learners in any environment. Explore our many resources and services for an in-depth look at what we do.
A global community fostering positive change
