The focus of this action research project was to determine if interventions were effective when toilet training a five-year-old boy diagnosed with autism spectrum disorder (ASD). Evidence based interventions were implemented over a six week period. Qualitative data were collected through observations, surveys, interviews, and journal notes. Quantitative data were collected by recording successful urinations in the toilet, accidents in the child’s pants, and compliance in using the bathroom. Analysis of the data collected suggests that the interventions were effective in toilet training a child with autism.
