Enlistment Screening Test (EST)
The vast majority of military applicants are processed through a MEPS, where they take the computerized format of the ASVAB (called the CAT-ASVAB, short for computerized-adaptive testing ASVAB), undergo a physical exam, and run through a security screening, many times all in one trip. The paper-and-pencil (P&P) version is most often given in high school and at Mobile Examination Test (MET) sites located throughout the United States. Most MET sites use paper versions of the test.
Mapping Out the ASVAB Subtests
The computerized format of the ASVAB contains ten separately timed subtests, with the Auto & Shop Information subtest split in two. The paper format of the test has nine subtests (the Auto & Shop Information subtests are combined). The two formats differ in the number of questions in each subtest and the amount of time you have for each one. The CAT-ASVAB now often contains tryout questions. These questions haven’t been used on an officially scored ASVAB; test-makers use your responses to them to ensure the questions are good enough to use on future versions of the test. Each tester sees 15 tryout questions in two, three, or four of the subtests. These questions don’t count toward your score, but you still have to answer them. The tryout questions are only on the computerized version of the test; they’re not on the paper version. When you get tryout questions in a subtest, you get extra time to complete it.
Table 1-2 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; you can also see which chapters to turn to when you want to review that content.
