The impact of the Self-Determined Career Development Model (hereafter called the Self-Determined Career Model) on the job performance of four adults with moderate intellectual disability employed in competitive work settings was examined. 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 participants achieved their self-selected goal at levels that exceeded the expectations of their supervisor and job coach. Findings extend the current line of research utilizing the Self-Determined Career Model and support the use of this model by personnel providing support to individuals with disabilities in work settings.
