The purpose of the research is to develop psychological measures that will increase the effectiveness of operational classification of enlisted men so that in training and assignment the Army can make optimal use of the potential and developed skills of its manpower resources. The current phase of research on classification techniques is directed toward integration of findings on test effectiveness in a reorganized Army Classification Battery and a reconstituted system of aptitude areas. A battery of 21 experimental tests, plus current operational tests, was analyzed over a broad range of military occupational specialties MOS to identify the most effective tests or combination of tests for differential prediction of final grade in the appropriate Army training course. Twenty MOS samples with heavy representation of jobs in the electronics and electronics repair area were used. Tests selected for maximum absolute validity across MOS were compared with those selected to yield maximum differentiation among the MOS studied. Patterns of validity reflected the usefulness of key ACB tests--Arithmetic Reasoning, Automotive Information, Electronics Information,Verbal, and Army Clerical Speed--in differentiating between broad MOS groups. Newly developed motivation-type scales contributed substantially. Perceptual measures and arithmetic operations tests appeared promising.
