Validity of the 4 aptitude indexes derived from the Airman Qualifying Examination, Form F, was determined for final grades in 49 airman training courses. The selected samples graduating in 1961 ranged in size from 30 to 2233 with only 3 courses that had less than 100 graduates. Appropriateness of the selector indexes for their specialty clusters was evidenced by their having the highest validity for all but 2 of the 49 courses. The Electronics AI was the most effective, the Administrative AI the least. 8 figures illustrate graphically the relationship between scores on the aptitude index and success in training. These validation data demonstrate that the Airman Qualifying Examination is an effective instrument for use in assigning enlistees to technical training.
