The composite of Armed Services Vocational Aptitude Battery (ASVAB) subtests used to select applicants for entry-level training in Army clerical schools was evaluated by correlating composite scores with training performance scores. Comparisons were made between the multiple R for this optimal set of predictors and that for the composite of subtests currently used for clerical classification. In 9 of the 12 samples studies, a mathematics subtest (either arithmetic reasoning or mathematics knowledge) had the highest single-predictor validity correlation with course grade criteria. When the subsamples were combined, a composite of arithmetic reasoning, paragraph comprehension, and mathematics knowledge test scores had the highest multiple R with the criterion, significantly higher than the correlation obtained for the composite of subtests currently used. The results of the evaluation will be used by the Deputy Chief of Staff for Personnel to consider modifications of the clerical aptitude area composite that would raise the expected performance of soldiers in clerical occupations.
