What are the Subtests on the ASVAB?

By Rod Powers

The computerized format of the ASVAB contains ten separately timed subtests, with the Auto & Shop Information subtest split in two (also, one small subtest is geared to Coding Speed for a few Navy jobs; Very few people test for these jobs).

The paper format of the test has nine subtests. The two formats differ in the number of questions in each subtest and the amount of time you have for each one. This list outlines the ASVAB subtests in the order that you take them in the enlistment (computerized or paper) and student (paper only) versions of the test.
