This manual is the response of a National Institute on Rehabilitation Issues (IRI) Prime Study Group to charges given to the group by the National IRI Planning Committee to develop a meaningful training and resource document on the multidisciplinary approach to vocational rehabilitation. The guide is organized in seven chapters that cover the following topics: (1) the historical development of the multidisciplinary approach to rehabilitation; (2) the multidisciplinary approach: implications for leadership in the national program; (3) state vocational rehabilitation administrators: response to a changing environment; (4) management for the future: a priority; (5) the counselor's role in the multidisciplinary approach; (6) impact on service delivery; and (7) improving rehabilitation programs through networking. A reference list is also included. Appendixes include the study group membership list, a list of organizations concerned with vocational rehabilitation program development, an outline of counselor techniques for case management, and a summary of the "Valley Project," a demonstration of multi-agency services considered to be a model for transitional services from school/institution to community. A marketing audit for a job development and placement program is also provided. (KC)
