The anecdotal benefits of implementing Universal Design for Learning (UDL) at postsecondary institutions are well documented. The literature suggests that UDL offers students with disabilities enhanced opportunities for engagement, expression, and academic performance. Responding to the call by educators for empirical evidence of UDL's beneficial effects on student learning, performance, persistence, and ultimately retention, this study measured changes and/or improvements in instruction as perceived by students following UDL instructor training and subsequent course delivery modifications. This study also describes the process that was undertaken to develop and implement pre- and post-student surveys, and points the way toward further research regarding the benefits of UDL implementation to postsecondary education.
