Medical professionals commonly report having inadequate training providing care for individuals with intellectual and developmental disabilities (IDD). This pilot study aimed to address this gap through a virtual Objective Structured Clinical Examinations (OSCE) with individuals with IDD as patient educators for 25 first- and second-year medical students (OSCE participants). Quantitative data through the Prediger competency scale and qualitative data through a semistructured interview were analyzed. OSCE participants reported a significant increase (p < 0.05) in self-perceived competency scores when comparing pre- and post-OSCE scores. Qualitative analysis yielded themes corresponding to improving skills, practice considerations, and perspectives and biases changes. These results suggested that this virtual OSCE promoted the development of self-perceived clinical competency and comfort providing care for individuals with IDD.
