The handbook, first of a series of six, is designed to give the school administrator an overview of Project Employability (Ohio), a program to meet the employability needs of low functioning educable and high functioning trainable mentally retarded high school students. Chapter I describes each of six products: Community Job Task Analysis, Employability Assessment Instrument, Employability Curriculum, Home/School/Work Handbook, Student Work Performance Handbook, and Employability Administrative Handbook. Chapter II outlines a step by step procedure for introducing the project materials to an instructional staff. The final chapter contains a project summary report which reviews the program and presents evidence of effectiveness. Noted among the process and student outcome objectives are development and field testing of an employability curriculum with long and short term instructional goals, activities and resources, and improvement of students in at least one of 21 employability performance skills. Appendixes include a brochure, community job cluster, sample task analysis, sample task detail, employability skill definitions, and a sample student profile. (SB)
