ASVAB for the Navy: How Scores Work and How to Prepare
The difference between your AFQT and your line scores, why both matter for the job you get, and a study approach that works.

In this guide
The Armed Services Vocational Aptitude Battery is the test every enlisted applicant takes. It is not an IQ test and it is not pass or fail in the usual sense. It measures what you know in a set of areas and uses that to predict how you would do in different kinds of training.
What is on the test
| Subtest | What it covers | Counts toward AFQT? |
|---|---|---|
| Arithmetic Reasoning (AR) | Maths word problems | Yes |
| Mathematics Knowledge (MK) | High-school algebra and geometry | Yes |
| Word Knowledge (WK) | Vocabulary and synonyms | Yes |
| Paragraph Comprehension (PC) | Understanding written passages | Yes |
| General Science (GS) | Life, earth and physical science | No |
| Electronics Information (EI) | Circuits and electrical basics | No |
| Auto and Shop Information (AS) | Vehicles, tools and workshop practice | No |
| Mechanical Comprehension (MC) | Mechanical and physical principles | No |
| Assembling Objects (AO) | Spatial reasoning | No |
AFQT: the score that gets you in
The Armed Forces Qualification Test score is calculated from the four subtests marked above. It is reported as a percentile from 1 to 99, which shows how you performed compared with a national reference group — a score of 60 means you did as well as or better than 60 percent of that group. It is not the percentage of questions you got right.
Each service sets its own minimum AFQT score, and applicants without a traditional high school diploma usually need a higher one.
Line scores: the scores that decide your job
Each Navy rating requires a minimum result on a particular combination of subtests. A technical rating might combine maths, electronics and science; an administrative one leans on verbal and arithmetic scores. This is why the non-AFQT subtests matter: skipping them in your preparation can close off the ratings you actually want.
If you already have a field in mind, ask your recruiter which subtests feed its line score and put extra time there. Our Navy Career Explorer shows the main career fields.
Where and how you take it
- At school, through the ASVAB Career Exploration Program, if your school offers it.
- At a Military Entrance Processing Station (MEPS) or a satellite test site, arranged by your recruiter. The computer version adapts to your answers, getting harder or easier as you go, and you cannot go back to change an answer.
- The PiCAT is an unproctored version some applicants take first; it is then confirmed with a short verification test at MEPS.
Can you retake it?
Yes, with waiting periods. Under the official retest policy you must wait one calendar month to retest after your first attempt, another calendar month before a second retest, and six months before any further attempts. Your most recent score is the one that counts, so retest only when you have genuinely prepared.

Frequently asked questions
Is the ASVAB hard?
It covers high-school level material, so difficulty depends on how recently you studied it. Most people improve noticeably with a few weeks of focused preparation.
What is a good ASVAB score for the Navy?
One that qualifies you for the rating you want. Higher AFQT and line scores open more options, including the most technical fields.
Can I use a calculator?
No. Calculators are not permitted, so practise arithmetic by hand.
How long are my scores valid?
ASVAB scores are valid for enlistment for two years.
