IT IS the constant task of the pediatrician to explain medical conditions in understandable language to parents, children and other lay persons. In addition, he is often called upon to give interpretation to nonmedical professional people, such as social workers or juvenile court judges. Particularly frequent and important is the demand and occasion for the pediatrician to help the school teacher to understand the problems of a chronically ill or handicapped child in her class so that she may manage the child to his best interest and may adapt her educational techniques to fit his needs. Then she can feel more confident in her ability to accept into her group a child who is "not normal."
