STABILITY OF AIRMAN CLASSIFICATION TEST SCORES
Abstract
Stability of Air Force test scores were examined as one facet of the long-range prediction problem. Data for high school students were obtained on Air Force classification tests from an original test session at midyear of 1958-59 and a retest session one year later. Control groups were formed from students at three class levels tested only once. Mean growth in aptitude test scores between control class groups was of the same magnitude as the retest gains except for two of the airman tests, Figure Recognition and Clerical Matching. Conversions of Air Force aptitude indexes to World War II AGCT scores show that Mechanical Index scores averaged greater gains from year to year than AGCT, while the Administrative Index showed lower gains than AGCT. Stability coefficients for the individual tests were lower than their reliabilities, but the only appreciable differences were for Biographical Data scores, Figure Recognition, and Clerical Matching. Intercorrelations of tests obtained over the one-year period were not appreciably lower than those obtained without intervening time. (Author)
