An administrative and curriculum guide are presented for the High School/Preschool Partnership Program in which high school students gain experience with handicapped preschoolers in a mainstreamed setting. The program is intended to expand services to high schoolers (parenting skills and career skills) as well as preschoolers. The administrative guide provides basic information about the program, component descriptions, program development formats, program benefits, potential implementation problems, program specifications and variations, evaluation data, and cost background. The curriculum guide, designed for teachers, describes the daily operation of the program and provides lessons for the high school students about handicapped preschoolers. Materials include background for teachers on special education and early intervention, schedules for high school and preschool students, lessons and activities to prepare high schoolers to work with handicapped students, evaluation materials for the teacher, and resources.
