This self-teaching workbook is designed to provide parents of developmentally disabled adolescents with basic information about the transition of severely handicapped youth from secondary school into community living. An initial parent quiz is followed by six chapters which address the following topics: (1) "What Is Transition?"; (2) "The MESH (Montana Model for Education of the Severely Handicapped) Model for Transition"; (3) "Parent Roles in Transition Planning"; (4) "Parents and the Individual Education Program"; (5) "Transition Issues" (family decisions, financial planning); (6) "The Big Step" (educational or training opportunities, vocational options, living arrangements, recreation and leisure options). Each of the six chapters is divided into individual lessons which focus on a particular topic, followed by written exercises. A bibliography concludes each chapter. An extensive glossary and sample planning forms comprise the two appendices. (JW)
