It was assumed that multidimensionality existed in the individuals to whom test items were being administered, i.e., that the correct or incorrect responses given by an individual…

The Armed Services Vocational Aptitude Battery (ASVAB), a battery of 10 vocational tests, was administered to a national probability sample of nearly 12,000 young people, 15 to 23 years of age.

Six new forms of Armed Services Vocational Aptitude Battery (ASVAB) were developed. These new forms were equated to a standard reference test, ASVAB 8a, using normative data based on a 1980 weighted probability sample of American youth, ages 18-23. Equating allows the services to report the distributions of examinee ability on a common metric or…
