This guide is intended to address the many roles and functions of job coaches in various employment settings. The guide was written to assist the following groups of service providers: (1) vocational rehabilitation personnel working in rehabilitation facilities, sheltered workshops, work activity centers, or other supported work-oriented programs; and (2) school system personnel, specifically those involved with work experience or work study transitional programs. The materials included can be used as a self-study or inservice training programs text, an aid to supervisors planning to hire job coaches, or a guide for agencies seeking to establish supported work programs. The following topics are covered in the individual chapters: vocational evaluation, job development, job analysis, client-to-job matching, on-the-job training, and worker evaluation. Each chapter describes techniques and procedures that have been found to be effective in actual job coaching situations. Initial employer contact, employment survey, position/job site survey, job analysis, client analysis, client-to-job matching, task analysis, production rate, and supervisors' employee evaluation forms are also provided. Appendixes include information about supplemental security income and lists of agencies serving and journals dealing with disabled populations and related employment issues. (MN)
