The first ASVAB (Armed Services Vocational Aptitude Battery) was introduced in 1968 as a paper-and-pencil (P&P) test as part of the Student Testing Program. In 1973, the Air Force began using the ASVAB, followed by the Marine Corps in 1974. From 1973-1975, the Navy and Army used their own test batteries for selection and classification.
In 1974, the Department of Defense decided that all Services should use the P&P-ASVAB for both screening enlistees and assigning them to military occupations. Combining selection and classification testing made the testing process more efficient. It also enabled the Services to improve the matching of applicants with available job positions and allowed job guarantees for those qualified.
In 1976, the ASVAB was first used by all of the Services for selection and classification. Since 1976, a variety of content changes have been introduced to the test.
