The ASVAB is routinely reviewed to eliminate any potential biases from questions and scoring. The exam underwent a major revision in 2002. Two years later, a renormalization of the percentile scoring system was performed to ensure that a 50 percent score represented performing better than 50 percent of all test takers. The 10-section ASVAB improves the matching of volunteers with available jobs and helps match job openings with qualified individuals.

The Armed Services Vocational Aptitude Battery (ASVAB) is a series of aptitude tests developed by the Department of Defense. It is used to determine and predict the potential/future success of military candidates. The ASVAB military entrance exam is a part of the U.S. Military screening process and is administered annually to more than one million military applicants.

The various armed forces adopted all of those aspects in 1976. At that point in time, the test was in its written form rather than today’s more common form (computerized test format). The written form covers all of the previously mentioned areas as well, which is why both forms are still available. All-in-all that answers the question concerning the intention of the test.
