The CAST UDL Guidelines 3.0
In the 2024 update of the CAST UDL Guidelines, the bottom row of the framework has been labeled as Executive Function. This indicates that the three guidelines in that row–Emotional Capacity, Building Knowledge, and Strategy Development–all represent research-based ways to support students' executive functions.

The UDL Guidelines are a living, dynamic tool that is continuously developed based on new research and feedback from practitioners. After launching our most recent effort to update the UDL Guidelines in 2020, on July 30th, 2024 we are thrilled to release UDL Guidelines 3.0!
This new iteration of the UDL Guidelines responds to a strong call from the field—both practitioners and researchers alike—to address critical barriers rooted in biases and systems of exclusion for learners with and without disabilities.
