The purpose of this study was to examine the impact of the Self-Determined Career Development Model (SDCDM) on the job performance of four adults with moderate intellectual disabilities employed in competitive work settings. Employees learned to set work-related goals, develop an action plan, implement the plan, and adjust their goals and plans as needed. A multiple baseline design across employees was implemented. All four participants achieved their self-selected goal at levels that exceeded their supervisor and job coach expectations. Findings extend the current line of research utilizing the SDCDM and support the use of the model by personnel providing support to individuals with disabilities in work settings.
