Validation of Non-Verbal Measures for Selection and Classification of Enlisted Personnel.
Abstract
A non-verbal aptitude battery was administered to 13,584 non-prior-service male basic airmen. Additional aptitudinal and educational data were combined with the non-verbal tests to assess their usefulness in predicting final technical school grade. Although the correlations between the individual subtests and final school grade (FSG) were not found to be statistically significant in every technical course, figure analogies and dial reading appear to demonstrate the highest relationship with FSG. The multiple correlations based on a composite of all non-verbal subtests reached statistical significance in over 75% of the technical areas in both the total sample and lower ability subgroups, and the composite was found to make an unique and significant contribution to the prediction of FSG over and above the Armed Forces Vocational Aptitude Battery (ASVAB-3) Selector Aptitude Index (AI) along. When additional aptitudinal and educational data were added to the composite, the predictive efficiency of the composite increased. These findings substantiate the validity of the non-verbal test measures and the potential utility of including these measures in future operational test batteries. (Author)
