Forty-six tests from the Kit of Factor-Referenced Cognitive Tests, published by the Educational Testing Service, were used in an investigation of the factor structure of the Armed Services Vocational Aptitude Battery. The overall kit contains 72 fairly short tests that have been developed to serve as markers for 23 factors that appear in the literature on cognitive abilities. Subjects were 6,931 Air Force recruits entering training at the Recruit Training Center at Lackland Air Force Base (Texas). The study was designed in such a manner that approximately 1,610 recruits took each of the 46 factor-referenced tests. The gender proportion of the examinees was consistent with that of the general population of Air Force recruits. Each completed test booklet was scored by three independent judges. Twenty-two tests selected from the Kit were reproduced, administered, and scored in very large numbers without encountering problems and without requiring precautions to avoid problems. Some of the remaining tests warranted minor precautionary actions. Other tests were the focus of administration problems that required testing of additional subjects or modifying scoring procedures and answer keys. Suggestions concerning the use of these tests by others interested in research on cognitive abilities are provided. Two data tables are included. (TJH)
