Although researchers have clearly identified evidence-based ABA practices for children with autism, the research-to-practice gap in implementation continues to exist in schools. This may be due to lack of staff development and knowledge in specific instructional methods (Odom, Collet-Klingenberg, & Hatton, 2010). Moreover, the delivery of training may be a factor in staff development. For example, workshops are one of the most common ways professionals access training (Brock, Huber, Carter, Juarez, & Warren, 2014). However, workshops often have limited impact on implementation of new knowledge. Advances in technology have made online training more accessible for educators as a delivery option. The present research study examines the impact of web-based modules among special education staff who support students with autism in self-contained classrooms.
