Terms related to special education on Ohio and educational terms used in diagnosis/evaluation are also defined. The second section provides general information concerning the Ohio Rehabilitation Services Commission. Discussion centers on the Commission's purpose and range of services, vocational rehabilitation process, status system, confidentiality, employment outcomes, and closure information. The final section presents a model for the referral of severely handicapped students. Project INTERACT's model linkage system is described. Other contents include charts depicting the primary interagency communication network; model linkage system flow charts reflecting the educational continuum existing in Columbus City Schools, adult vocational continuum existing in Franklin County, and points of contact established to create a linkage system; and model procedures for the referral of severely handicapped students from education to rehabilitation.
