This paper aims to share the results of an on-demand professional development series provided to teachers of inclusion classrooms. The doctoral candidate created the YouTube channel "IEP: Facts & Hacks" and distributed it to general education and dually certified teachers throughout eight weeks. All videos within this channel contain information on comprehending information from a student IEP, implementing IEP accommodations, and differentiating classroom instructional materials. Findings support that when teachers of inclusion classrooms are given applicable and accessible professional development on special education topics, the self-efficacy of those teachers increases.
