This manual was prepared by the Regional Rehabilitation Exchange (RRX) project to assist rehabilitation and independent living organizations and programs in submitting information to gain recognition as an exemplary program model for transitional services. The manual is intended for programs and organizations in Arkansas, Louisiana, New Mexico, Oklahoma, and Texas. RRX transitional services include any short-term training activities and/or related services that promote the transition of persons with disabilities to competitive working life and may be targeted to persons with a wide range of disabilities, such as learning disabilities, mental retardation, mental illness, and/or physical disabilities. Services may be offered through secondary or postsecondary schools or community-based programs and facilities for adult clients. The manual provides information about the background and purposes of the RRX, identifies the scope of the RRX project, lists the prerequisites and criteria for validation, describes the RRX validation process, identifies 10 critical factors (program goals and objectives, target population, documentation and good recordkeeping, success rate, cost effectiveness, comprehensiveness, evaluation criteria, staffing patterns, transportability, and innovativeness) used in determining exemplary programs, provides information on completing the Information Request Form, and identifies implications for validated programs. A completed sample Information Request Form for transitional services is included. (CML)
