Our purpose in this study is to offer a more comprehensive understanding of how students with intellectual and developmental disabilities attending postsecondary education programs are prepared for competitive employment. Data collected through a national survey indicate that the vocational-related support services offered frequently by postsecondary education programs are: career or vocational counseling, person-centered planning, career or vocational assessment, career exploration, volunteering, internships or co-ops, natural supports, instruction on transitioning to paid employment and between paid jobs, and self-advocacy. The number of students receiving work-based experiences was larger in programs affiliated with a four-year institution. No differences exist in the provision of work-based experiences, workplace supports, and connections with adult agencies based on location. We discuss implications for practice and future research.
