Using a three-round Delphi survey, researchers explored parent perspectives regarding the personal competencies students with intellectual disabilities (ID) needed to be better prepared for participation in an Inclusive Postsecondary Education program (IPSE). An expert panel comprised of parents of students with ID in IPSE programs participated. Three Delphi rounds consisted of open-ended questions and cycles of subsequent rating scales on identified perspectives to establish a quantitative basis for consensus. The parent panel reached consensus on a list of 30 personal competencies that support student preparation for IPSE. A description of the methodology, results, and implications for practice are discussed.
