That year, a small group of hospital-based education researchers and clinicians established the Center for Applied Special Technology, or CAST, to explore ways of using computer technologies to improve education for all children, especially those with disabilities.
As CAST researchers tested and refined their vision and principles during those early years, they came to a new understanding of how to individualize education using flexible methods and materials. They called this approach Universal Design for Learning (UDL).
Today, UDL frames all of CAST's research, development, and service. Through strategic collaborations, CAST is seeding the fields of curriculum planning, software development, state and national policymaking, teacher preparation and support, and education research with UDL-based solutions.
