The purpose of this manual is to provide a source of basic material which can be used by state agency personnel for the orientation of new counselors, for beginning courses in rehabilitation counselor training programs, and for inservice training of experienced rehabilitation counseling personnel. This revised edition of the manual was completed and written under the direction of John F. McGowan, with the assistance of Thomas L. Porter. The revision attempts to incorporate suggestions received from State training supervisors who have used the original publication. Major sections are: (1) Introduction and Background, which includes basic concepts of vocational rehabilitation, related legislation, and the locating of persons who need help, (2) Preliminary Study and Planning, which includes initiating the rehabilitation process, determining eligibility, and making a medical, psychological, sociocultural, and vocational assessment of the client, (3) Client Services, which includes planning services, providing prevocational and rehabilitational counseling, and locating places of employment, and (4) The Rehabilitation Counselor's Role. Suggested readings are included at the end of each section, and several client-study case abstracts are appended.
