Preparing teachers to implement evidence-based practices for students with autism spectrum disorder (ASD) is a pressing need. We surveyed 456 teachers and administrators in a southern state about professional development related to educating students with ASD. Specifically, we were interested in confidence in implementation of evidence-based practices, interest in accessing training on these topics, perceived benefit of different avenues of professional development, and interest in accessing these avenues. Overall, teachers were not very confident in their ability to implement evidence-based practices and address important issues for students with ASD. Surprisingly, lower confidence was not related to increased interest in training. In addition, teachers and administrators perceived workshops to be a more beneficial and attractive avenue of professional development compared with coaching, despite empirical evidence to the contrary. We offer possible explanations for these findings and share implications for administrators, technical assistance providers, and policy makers who make decisions about professional development opportunities.
