The report describes a manpower assessment and classification system for criminal offenders directed towards making practical training and job classification decisions. The model is not concerned with custody classifications except as they affect occupational/training possibilities. The model combines traditional procedures of vocational psychology, such as job aptitude testing and individual vocational counseling, with more recent technologies, such as life planning exercises, behavioral simulations of job situations, and the "assessment center" concept. The assessment center, the central feature of the classification model, is designed to be conducted at that time just prior to most inmates being assigned to training programs, and is thus labeled a "Mid-Sentence Career Development Center." Offenders would be placed in a variety of behavioral simulations to reveal a profile of strengths and weaknesses to a staff composed of professionals and prison officials. Prior to release, inmates would be scheduled for a "Pre-Release Career Development Center," designed to provide inmates with critical job seeking skills and to continue the life work planning program begun earlier. An evaluation design is included. A site visit protocol form, descriptive data from an inmate survey, information on the assessment center, life planning activities, and a discussion of work samples are appended. (Author/JB)
