The Armed Services Vocational Aptitude Battery ASVAB was administered five separate times to fifty-seven men and women of military service age. The objective was to determine to what extent means and cross-session correlations are stable over sessions. Ten individual subtests, the derived ASVAB area composites N10 and the Armed Forces Qualification Test AFQT were examined for stability. The means and dispersions of scores for this population were below the national average. Means increased over sessions .5 standard deviations or more on half the subtests and consequently on most of the composite scores. Correlations for the composites were largely stable over sessions. Correlations between composites were generally lower than within composites. The implications of practice effects for paper and pencil as well as automated selection tests are discussed.
