The purpose of this study was to evaluate the effectiveness of UDL-based enhancements of an online module on functional behavior assessment. The UDL framework is an instructional design framework designed to enhance access, engagement, and learning using three overarching principles: multiple means of engagement, multiple means of representation, and multiple means of action and expression. The researcher utilized a two-group randomized control trial (RCT) with pre- and posttest measures. The control group completed a publicly available module on functional behavior assessment while the intervention group completed an enhanced version of the same module. Results demonstrate that both the intervention and control group demonstrated similar levels of knowledge gains, indicating that UDL instructional design enhancements are equally as effective as current instructional design practices in online, asynchronous modules. Given the legislative mandates for the use of UDL and ethical considerations regarding student accessibility, UDL is recommended for continued use in higher education and other professional learning for educators.
