The results of a pilot study of a UDL assessment used within synchronous online K-8 classrooms are presented. Increased participation in online curriculum by students with special learning needs is prompting research on online teaching and learning. Researchers examined online curriculum alignment with the Universal De- sign for Learning (UDL) framework using a 68-item UDL measurement instrument. The study supports the implementation of UDL to enhance online classroom instruction with current research. Teaching techniques, assessment considerations and the use of UDL to improve student outcomes are discussed.
