The paper discusses program development at the Granville Work Preparation Centre in Australia, which teaches mildly retarded adolescents work and social skills. Some broad parameters considered in program development are listed and include recognition of the Center's industrial setting, and disruption in routines through extra movement of trainees within work areas. Ten principles of instruction used at the Center are presented and include the use of task sequencing; and the use of task analysis. Fourteen training strategies and techniques are listed and include modeling, roleplay, and visits to community facilities. Programs developed at the Center are briefly summarized, among them deficit social skills and social development training programs, a training program for instructors, sound and slide programs on radiator assembly, an experimental program for modification of conceptual tempo, and an experimental reading program.
