The objective was to calibrate the Armed Forces Qualification Test AFQT composite of the Armed Services Vocational Aptitude Battery ASVAB Forms 8a, 8b, 9a, 9b, 10a, and 10b to the metric of the AFQT Form 7a AFQT-7a and to compare these outcomes to the operational calibration tables implemented 1 October 1980. A sample of applicants for military enlistment was administered one form of ASVAB and the AFQT-7a in counterbalanced order. From this target sample of 22,400, a males only sample of 15,115 was developed through data editing techniques designed to exclude females and cases with incomplete or unusable data. For analytic purposes, this edited sample was separated into six samples based on the six forms of ASVAB administered. Data were collected at 20 geographically dispersed Armed Forces Examining and Entrance Stations AFEES on the six forms of ASVAB and the AFQT-7a. Each of the six males only samples was edited and scored, and descriptive statistics were computed. Percentiles for both the ASVAB and the AFQT-7a were equated and smoothed by a polynomial regression procedure. Each sample was split in half, and the equating and smoothing were repeated on each half sample. Since results were consistent among the large sample and the two half samples, they were accepted. In order to investigate the similarity of the equated scores across the forms, root-mean-square RMS and average absolute deviation AAD measures were computed between the various equating tables. A comparison of the forms found them to be equivalent when they were equated to AFQT-7a. Author
