What the ASVAB covers
The ASVAB is a set of subtests: General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics Information, Auto Information, Shop Information, Mechanical Comprehension and Assembling Objects.
On the computer, Auto Information and Shop Information are separate subtests that are combined into one Auto and Shop score. On paper they are one combined subtest.
The AFQT score
Your AFQT score is computed from four subtests: Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension and Mathematics Knowledge. It is reported as a percentile from 1 to 99, which compares you with a reference group of 18 to 23 year olds from a 1997 national study.
There is no single pass mark. Each service branch sets its own minimum score.
Computer or paper
The CAT-ASVAB runs on a computer and adapts the questions to your answers. In a proctored setting it takes about 2 hours on average, and your scores are available right after the session.
The paper-and-pencil ASVAB is given only at a handful of sites. It takes 3 to 4 hours including instructions, and scoring usually takes a few days. On paper, each subtest has a fixed length and time limit:
- General Science: 25 questions, 11 minutes
- Arithmetic Reasoning: 30 questions, 36 minutes
- Word Knowledge: 35 questions, 11 minutes
- Paragraph Comprehension: 15 questions, 13 minutes
- Mathematics Knowledge: 25 questions, 24 minutes
- Electronics Information: 20 questions, 9 minutes
- Auto and Shop Information: 25 questions, 11 minutes
- Mechanical Comprehension: 25 questions, 19 minutes
- Assembling Objects: 25 questions, 15 minutes
Where you take it
The proctored test is given at a Military Entrance Processing Station (MEPS), of which there are 65 across the U.S. and Puerto Rico, or at a satellite MET site. Bring a valid ID and be on time: late arrivals are turned away and have to reschedule.
The PiCAT is an unproctored version you take at home with an access code from a recruiter. The code expires 30 days after it is issued, you must finish within 48 hours of starting, and it is only for people who have never taken the ASVAB. If you qualify, a short proctored verification test follows within 45 days.
How to prepare
Practice every subtest, with extra time on the four AFQT subtests. The practice tests on this site use the paper test's length and time limit for each subtest, so you get used to the pace.
