The experimental design randomly assigned 600 offenders to either an experimental or a control group. The experimental group participated in a vocational training program that included pretraining evaluation and counseling, priority for entry into vocational classes, pre-release employment counseling and post-release job placement. The results indicate that members of both groups attempted equal numbers of programs, experimental group members completed more vocation programs, and experimental group members successfully completed more programs than did members of the internal control group. The results also suggest that the program studied required 1.5 years to reach "steady state," a period longer than that allowed for many previous program evaluations. 5 tables, 2 figures, and 13 references.
