Inclusive postsecondary education (IPSE) programs can provide young adults with IDD opportunities for training and experiences in continuing academic instruction, transition goals, independent living as well as employment. Parent readiness is an important aspect of having young adults embrace their increasing independence. While the prospective student must be ready to attend the institution, understanding the "readiness" of parents will help to guide the development of additional parent related materials to help them with the transition process. It was with this intent that the Graff Parent Readiness Scales (GPRS) were developed. The purpose of this study is to conduct an exploratory factor analysis on the GPRS in order to establish construct validity of the instrument. Results showed the six factor solution. The implications for IPSE programs is clear that by addressing parental concerns and forging an alliance with the institution students with IDD will have greater success.
