A work study program was developed for five educable and trainable students in a high school transition class. A teacher's aide was trained as a job trainer at the workplace prior to program implementation; ongoing informal discussions at school with the program developer helped with problems that developed. The work study program developed in-class job readiness skills together with on-site work experiences at a community-based work environment to prepare students for productive work in society after graduation. Program success depended on job trainer effectiveness that enhanced student skill acquisition and readiness for post-graduation paid supported employment. Results showed that the targeted transition students performed on the job, developed necessary skills and self-confidence, and provided employers with a reliable, attentive, punctual, and motivated work force. The job trainer, who nurtured on-site student skill development, maintained a viable program. (Twenty-nine references are provided. Appendixes include a sample student attendance record, sample student skill acquisition checklist, a sample parent survey, a sample job trainer competency evaluation, and a sample student employment appraisal.)
