Water safety skills are vital for the safety and well-being of all individuals but especially for individuals with autism spectrum disorder (ASD). Research regarding on-deck water safety behaviors and water safety skills for individuals with ASD levels 2 and 3 is limited. Therefore, the purpose of this study was to evaluate the effects of behavior analytic strategies in teaching water safety skills to children diagnosed with ASD level 2 and 3. A multiple-probe design across three participants was utilized in which participants did not enter intervention until their baseline data were stable and the participant before had stable intervention data. Each participant engaged in 100% of the measured water safety behaviors by the end of the study. The results suggest that this intervention may increase safe on-deck behavior in a community pool setting. Suggestions for future research and implications for practice are discussed.
