Child development and disability: competency-based clerkship.

: The training of medical students in the subject of mental retardation is important in broadening the physician's role in dealing with chronic disability. A competency-based training model is presented which specifies competencies, achievement methods, and evaluation procedures for a clerkship. The focus for training is on developing practical skills and a positive orientation toward developmental problems. Evaluative measures for 12 students rotating through the clerkship showed positive knowledge and attitude changes. Competency-based training is recommended as a model for preparing physicians to serve as advocates and resources for persons with chronic conditions.
