Vocational education, special education, and vocational rehabilitation are the three primary providers of school-to-work transition services to handicapped youth. Each of these three sectors has a vital role to play in the following aspects of transition services: identification, assessment, individualized program planning, program implementation and training activities, service delivery systems, employment services, and architectural barrier removal. By working to coordinate and avoid unnecessary duplications in their services, vocational and special educators and vocational rehabilitation practitioners can achieve substantial cost savings, reduce gaps in service, maintain continuity in services to clients, share state-of-the-art information and approaches, and develop joint political action campaigns. To improve coordination among the three primary providers of transitional services to disabled youth, practitioners and policymakers must work to resolve conflicting pieces of pertinent Federal legislation, address problems relating to duplication of services, obtain increased cooperation of business, and develop linkages on a one-to-one level. Various exemplary programs addressing current problems in coordinating transition services do exist and are described in the literature on transitional services for handicapped youth. (MN)
