Armed Services Vocational Aptitude Battery: Development of Forms 11, 12, and 13. Volume 1.
Abstract
This report describes the development of the Armed Services Vocational Aptitude Battery (ASVAB) Forms 11, 12, and 13. The items for the new forms were supplied by the Air Force Human Resources Laboratory (AFHRL). They were administered to examinees in Recruit Training Centers (RTCs) along with items in the ASVAB 8b, a test battery parallel to the reference test used in this study, ASVAB 8a, as part of a previous research effort. Using the pretest data, eight new power subtests were constructed by matching classical item statistics for the new items to corresponding ASVAB 8b items. Comparisons of classical and item reponse theory (IRT) item statistics suggested that newly developed subtests should be parallel among themselves and to ASVAB 8b. Complete new ASVAB test batteries and ASVAB 8a were administered to examinees in RTCs using an equivalent-groups design. In addition, partial batteries of ASVAB Form 11a (judged to be the most 'central' of the new forms) and ASVAB 8a were administered to examinees at Military Entrance Processing Stations (MEPS). The demographic statistics for the RTC adn MEPS samples indicated that the assumption of the equivalent-groups design were met. Summary score statistics were computed for each subtest administered in order to determie if like-named subtests were parallel. Classical item statistics and IRT parameters showed that the new subtests were more parallel among themselves than they were to the like-named ASVAB 8a subtests.
