The ASVAB subtests are designed to measure aptitudes in four domains: Verbal, Math, Science and Technical, and Spatial. The table below describes the content of the ASVAB subtests. The subtests are presented in the order in which they are administered.

* The ASVAB is administered via both paper-and-pencil and computer formats in the Enlistment Testing Program. AI and SI are administered as separate subtests in the computer administration but combined into one single score (labeled AS). AI and SI are combined into one single subtest (AS) in the paper-and-pencil administration. Scores on the combined subtest (AS) are reported for both the computer and paper-and-pencil administration.
