A competitive employment transition model for individuals with mental retardation, learning disabilities, and behavior problems was evaluated in northern Utah. Employees in community businesses were taught to implement structured instructional and evaluation procedures to provide on-the-job training to disabled trainees. The results showed that co-workers positively influenced disabled workers' success on the job by teaching and monitoring their performance. Further, co-worker trainers' involvement positively impacted transition specialists' ability to provide placement, training, and support services to workers with disabilities in rural settings.
