Supervisor perceptions of employee competence in areas of work, social, and personal demands of the job often determine success or failure for the supported employee. This study involved three workers with disabilities who participated in a supported employment program. After being successfully hired in a job of their choosing, problems arose that jeopardized the successful completion of the placement phase. The workers used individualized self-determination contracts to improve supervisor evaluations. Specifically, they completed daily self-determination contracts to plan their work outcomes, manage their tasks, evaluate their performance, and make adjustments for their next opportunity to work. Results indicated that all three workers used self-determination strategies to improve their performance and meet the expectations of their respective employers.
