An impact analysis of the Vocational Opinion Index Transition System (VOITS) was conducted by studying the first six months of its implementation at a Minneapolis vocational training center. (The VOITS program provides skills training personnel with an early diagnosis of an individual's "Job Readiness Posture" and guidelines for the development and implementation of ameliorative activities which result in the modification of nonworker postures.) The participants in the study were placed at random into two groups: One group received only the vocational skills training and the other group received both the vocational training and the VOITS training. A before and after training measure of the "Job Readiness Posture" was given each group. After comparison, the results showed that the VOITS program significantly increases the number of trainees who obtain and maintain jobs upon completion of their vocational training. The study also revealed that VOITS can be successfully implemented in training institutions without additional personnel or capital equipment and that the system is cost effective, yielding a benefit of 17 times the cost of implementation for two years in the Minneapolis study. (A brief description of the implementation process is included.) (BM)
