Despite growing public awareness of ASD, many caregivers of children with ASD struggle to find opportunities for participation in community activities with appropriate accommodations. The current study evaluated the experiences of individuals with ASD who attended immersive theater performances specifically designed for individuals with ASD. Parents and teachers of 256 children and adolescents completed questionnaires regarding their pre-show expectations and post-show satisfaction with the performance. Analyses revealed that, on average, parents' and teachers' levels of satisfaction significantly outweighed their pre-show expectations. Based on researcher observations, audience feedback, and past research, a list of best practices for successful theater programming for individuals with ASD was compiled with the goal of widespread dissemination to increase accessibility of theater performances for neurodiverse audiences.
