People with intellectual disability (ID) experience negative consequences as a result of stigmas held by the public. Students with ID involved in inclusive postsecondary education (IPSE) programs demonstrate positive outcomes. This study examines the impact of an IPSE program on typically matriculating student attitudes toward ID. Explicit and implicit attitudes were measured at the start and end of a semester among IPSE volunteer peer mentors ( = 17) and an uninvolved student group ( = 14). Findings indicate that volunteers demonstrated lower discomfort after their volunteer experience, as measured by the Attitudes Toward Intellectual Disability Questionnaire (ATTID). Volunteers also demonstrated higher knowledge of causes and preference for interaction with people with ID than nonvolunteers. This demonstrates that volunteer involvement in IPSE positively impacts attitudes toward people with ID among typically matriculating college students.
