We describe intervention with 2 adolescent male students who had autism spectrum disorder (ASD) and resisted haircutting performed by care providers at a residential school. The students were exposed to a graduated hierarchy of steps including the presence of hair clippers, and increased duration of hair clippers against their scalp and hair. Edible reinforcement was presented contingent on completion of a step without interfering behavior. Both students learned to tolerate all of the steps in the graduated hierarchy and a full haircut with maintenance at 2‐, 4‐, and 6‐month follow‐up. The study supports previous tolerance‐training research with children and youth who have intellectual and developmental disabilities and resist personal care and hygiene routines.
