Exam Overview
The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple-aptitude test developed by the Department of Defense and administered by the United States Military Entrance Processing Command (USMEPCOM). It measures your strengths and potential for success in military training and careers, and it is the entrance test for every branch of the U.S. Armed Forces.
Purpose of the ASVAB


The Subtests
The ASVAB is made up of subtests that fall into two groups. The AFQT subtests measure the verbal and math skills every service member needs. The technical subtests measure science knowledge and mechanical, electrical, and spatial aptitude that qualify you for specialized jobs.

Number of Questions and Time Limits
The ASVAB is given in two formats. The CAT-ASVAB is a computer-adaptive test taken at a Military Entrance Processing Station (MEPS). The paper-and-pencil (P&P) ASVAB is given at some Military Entrance Test (MET) sites. On the paper version, Auto and Shop Information are combined into one subtest (AS); on the computer version they are separate.
| Subtest | CATQuestions | CATTime | P&PQuestions | P&PTime |
|---|---|---|---|---|
| GeneralScience | 15 | 12min | 25 | 11min |

| AssemblingObjects | 15 | 18min | 25 | 15min |
| Total | 135 | 197minmaximum | 225 | 149min |
The CAT-ASVAB times are maximums; most applicants finish in about 2 hours. You may also see additional unscored tryout questions on the CAT-ASVAB, which lengthen the time allowed for that subtest. Tryout questions look like scored questions, so treat every question as if it counts.
How the Computer-Adaptive Test Works
The CAT-ASVAB tailors each subtest to you. After you answer a question, the computer estimates your ability and selects the next question that best matches that level: a correct answer tends to bring a harder question, and a missed question tends to bring an easier one. Because each question is chosen from your previous answers, you cannot skip questions or go back to change an answer. The adaptive design measures ability with fewer questions, which is why the CAT has fewer questions than the paper version.

and change answers within the subtest you are working on, but not return to an earlier subtest.
Some recruiters also offer the PiCAT, an unproctored version of the ASVAB you can take on a personal computer. If you use it, you must later take a short proctored verification test at a MEPS or MET site to confirm your score.
The AFQT Score
The AFQT is calculated from four subtests. Word Knowledge and Paragraph Comprehension first combine into a Verbal Expression (VE) score, and VE counts twice in the AFQT formula.
AFQT = 2VE + AR + MK
VE (Verbal Expression) is derived from Word Knowledge and Paragraph Comprehension.
Your AFQT is reported as a percentile from 1 to 99. It shows the percentage of a national reference group of 18- to 23- year-olds who scored at or below your score. An AFQT of 60 means you scored as well as or better than 60 percent of that group. It is not the percentage of questions you answered correctly.
| Category | PercentileRange | Meaning |
|---|---|---|
| I | 93–99 | Wellaboveaverage |
| II | 65–92 | Aboveaverage |
| IIIA | 50–64 | Average |
| IIIB | 31–49 | Average |
| IVA IVB IVC , , | 10–30 | Belowaverage;enlistmentislimited |
| V | 1–9 | Wellbelowaverage;noteligibletoenlist |
Each service sets its own minimum AFQT for enlistment, and the minimum changes with recruiting needs. For applicants with a high school diploma, minimums generally fall in the low to mid 30s; applicants with a GED usually need a higher score, often 50 or more. Confirm the current requirement with a recruiter from the service you plan to join.
Line Scores
Each service adds specific subtest scores together to create its own line scores (also called composite or aptitude area scores). A job that involves electronics repair, for example, draws heavily on Electronics Information, Arithmetic Reasoning, Mathematics Knowledge, and General Science, while a mechanical job draws on Auto and Shop Information and Mechanical Comprehension. Because every subtest feeds at least one line score, the technical subtests matter even though they are not part of the AFQT.
Find out which line scores the jobs you want require, and give extra study time to the subtests that feed them. A strong AFQT gets you in; strong line scores open the jobs you want.

Preparation pays off directly on this exam. Higher scores open more jobs, more training options, and more enlistment incentives, and the skills you build while studying are the same skills your future training will draw on.
