This study was designed to develop a skill anaysis test battery which would aid in the prediction of achievement in two specific areas of training. A total of forty educable mentally retarded students in work study classes were selected for training. A three part rating scale specifically for this study was used as criterion meansure against the results of the battery of skill tests. The results yield nine skill test measures whose correlations with the criterion measures were statistically significant. The skill tests failed to produce significant correlations with the rating scale of general adjustment. The findings point to the need to separate these criteria of adjustment and achievement in selection of clients for training programs. (KJ/Author)
