Message to our Loyal Users of CAST UDL Lesson Builder, UDL Book Builder, UDL Exchange, and UDL Studio

On January 15, 2024, we will retire this website, along with a few others. We know it has many devoted followers who will be sad to see it go. We're sad, too.

Making these creative tools and offering them free-of-charge to educators, parents, and learners at no charge the past decade-plus has been our joy, we also know that usage is way down, funding for the tools ran out years ago, and their underlying technologies are no longer contemporary.

To ensure a smooth transition, we're providing a three-month sunset period so you have sufficient time to download any stored materials you may have on the sites and to find alternative tools. After January 15, we will also close all user accounts.

Thank you again for your understanding and be sure to visit www.cast.org to learn more about the exciting innovations we are pursuing today and tomorrow! Questions: questions@cast.org
