A study of the relationship between certain test scores and probable training and vocational success was made. Examined were three major training areas: power sewing machine, nurse aide, and clerical office work. Six tests were tested for their ability to predict success: the WAIS Revised Beta; Purdue Pegboard; English, California Surveys of Reading, Arithmetic, and Spelling; the GATB; and the Wonderlic Personnel Test. Two separate criteria for success were established, against which these tests were checked for predictive ability: success in training, and the ability to remain employed after six months. No clear patterns emerged on the expectancy tables. On the teacher rated group, most of the results were inconclusive. A clear cutoff point was seen on the WAIS Verbal IQ at the dull-normal range (Wechsler classification system). This was not seen on the Performance IQ table where there seemed to be no pattern. Reading achievement seemed to fall above the seventh grade level although low reading achievement seemed to have little to do with teacher ratings. In the nurse aide group placement failures were uncommon. (author/nl)
