This resource highlights teacher candidates’ understanding, experience, and application of Universal Design for Learning (UDL). The phenomenological study was conducted with teacher candidates in the special education major program and the elementary and special education dual major program. The emerging themes drawn from this study suggested that the participants’ understanding and application of UDL were promoted by explicit UDL training in the programs. The discussions include support, resources, procedures, benefits, and challenges in relation to teacher candidates’ understanding and implementation of UDL principles.
