How Long is the ASVAB?


Length of ASVAB Tests: Paper vs. Computer

The computer-based ASVAB takes an average of 1.5 hours to complete, while the paper-based exam takes about three hours to complete. Computer tests are given at Military Entrance Processing Station (MEPS) locations. Paper tests are utilized by most Military Entrance Test sites, which are satellite locations used only for test-takers located too far away from a MEPS facility.

ASVAB Subtests

ASVAB subtests are self-paced when taken on a computer, so it is possible that a student may complete the entire ASVAB faster than the total time allotted. For paper-based exams, however, an instructor paces all test-takers by the time allowed for each subtest.

Despite the difference in delivery, paper- and computer-based ASVAB versions are designed to measure the same knowledge so an individual's score typically would not vary if they took the test with a different format.
