Self-care in toileting is one of the areas that persons with autism frequently have difficulty managing and are often confused by training. In developing a toilet training plan, critical factors include teaching the skill where it will be used, considering modesty concerns, communicating clear expectations, ruling out medical problems, and providing reinforcement. Suggestions resulting from a survey of 100 parents of children with autism are reported, including waiting until the child is 4 years old to begin training, recognizing the problems caused by changes in routines and changes of bathrooms, and dealing with fears associated with toileting. Case histories are presented of three students at different skill levels in toileting. The long term goals, objectives, and procedures developed for each are discussed. Suggestions for specific challenging behaviors are offered. The booklet concludes that persons with autism can become independent in taking care of their toileting needs through the step-by-step progression of schedules, routines, physical assistance, cuing, reinforcers, and adaptations in clothing and environment.
