Initial Operational Test and Evaluation (IOT&E) of ASVAB (Armed Services Vocational Aptitude Battery) Forms 11, 12, and 13: Parallelism of the New Forms. Volume 1

摘要

Six new forms of the Armed Services Vocational Aptitude Battery (ASVAB) were developed and implemented on 1 October 1984. Between 1 October and 30 November 1984, these new forms and a reference form were administered to approximately 120,000 applicants to the US Armed Forces. Test data were analyzed to assess the parallelism of the new forms in the total sample of applicants who were tested during October and November 1984 and in separate male and female applicant samples. The distributions of subtest scores, the item statistics, and the interrelationships of the subtest scores were compared across the forms. There was some evidence of lower subtest mean scores on Form 12a, although this difference was not consistent for all subtests. Although results differ between the male and female samples, these differences did not appear to be systematically related to the form being administered and thus were not indicative of a sex-by-test-form interaction.
