ASVAB Score Explained: AFQT, Line Scores, and Percentiles
“Your ASVAB score” is really three different numbers. The AFQT (Armed Forces Qualification Test) score decides whether you can enlist at all, reported as a percentile from 1 to 99. Standard scores report how you did on each of the 10 individual subtests. Line scores (also called composite scores) combine specific subtests into the numbers each branch actually uses to assign jobs. Enlistment eligibility runs on the AFQT alone; job assignment runs on line scores.

People searching “my ASVAB score” usually mean the AFQT, since that’s the number a recruiter leads with. But if you’re wondering why you qualified for the Army but not for the specific job you wanted, the answer almost always lives in your line scores, not your AFQT.
How is the AFQT calculated?
Only four of the ASVAB’s 10 subtests count toward it: Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Word Knowledge (WK), and Paragraph Comprehension (PC). Word Knowledge and Paragraph Comprehension are first combined into a single Verbal Expression (VE) score, and the standard AFQT formula weights VE twice: AFQT is built from 2×VE + AR + MK. That raw combination gets converted into a 1-99 percentile against a reference sample of 18-to-23-year-olds from a 1997 national norming study. An AFQT of 60 means you scored as well as or better than 60% of that reference group, not that you answered 60% of questions right.
The practical effect: verbal skill carries as much raw weight in your AFQT as both math subtests combined. A test-taker who’s strong in math but weak in vocabulary and reading comprehension can be surprised by a lower-than-expected AFQT for exactly this reason.
What are the AFQT score categories?
The military doesn’t report your AFQT as a bare percentile in official paperwork; it also assigns you to one of eight categories, and those categories gate enlistment eligibility separately from the branch-specific minimums.
| Category | Percentile range | What it means |
|---|---|---|
| I | 93-99 | Top-tier scorer |
| II | 65-92 | Above average |
| IIIA | 50-64 | Average to above average; qualifies for most enlistment incentives |
| IIIB | 31-49 | Below average but broadly enlistable |
| IVA | 21-30 | Restricted enlistment, additional review |
| IVB | 16-20 | Restricted enlistment, additional review |
| IVC | 10-15 | Restricted enlistment, additional review |
| V | 1-9 | Federal law disqualifies enlistment |

Category IIIA and above generally qualifies for enlistment bonuses and incentives; Category IV applicants face extra restrictions layered on top of whatever their branch’s own minimum requires, and Category V is a hard federal disqualifier regardless of branch.
What’s the difference between a standard score and a line score?
A standard score is your result on one individual subtest, scaled so 50 represents the national average and roughly 16% of test-takers score 60 or above. You get 10 of these, one per subtest, and they’re the raw material for everything downstream.
A line score (composite score) is a specific combination of two or more standard scores that a branch uses to decide job eligibility. Each service builds its own composites from whichever subtests best predict success in a cluster of jobs. The Army’s General Technical (GT) score, for example, is built from VE + AR and gates a wide range of Army MOS options; it isn’t a subtest itself, it’s a combination of two subtests you already took. The Air Force builds separate Electronics and Mechanical composites from different subtest groupings for the same reason: predicting who’ll succeed in electronics-heavy jobs versus mechanically-heavy ones isn’t the same prediction problem, so it isn’t the same math. See our branch-by-branch AFQT and line-score breakdowns for the specifics that apply to your target service.
How long is my ASVAB score good for?
Two years from your test date. After that, scores can no longer be used to establish enlistment eligibility, and you’d need to retest. If you’re taking the ASVAB through your high school’s Career Exploration Program well before you’re ready to enlist, keep that window in mind. A score from sophomore year won’t still be valid for enlistment purposes as a senior two and a half years later.
What is a “good” AFQT score, concretely?
It depends entirely on what you’re solving for. To clear the lowest current branch minimum (Army’s 31, per multiple 2026 sources), Category IIIB is enough. To be competitive for enlistment bonuses and a wider range of jobs across any branch, you want Category IIIA or above, meaning 50 or higher. Our dedicated breakdown of what counts as a good ASVAB score goes deeper on how that threshold shifts depending on which specific job you want, since a highly technical job can require line scores well above the general enlistment bar even when your AFQT alone clears it easily.

FAQ
What’s the difference between AFQT and ASVAB? There’s only one exam. “ASVAB” is the full 10-subtest test. “AFQT” is the specific score computed from 4 of those 10 subtests that determines whether you can enlist. Every AFQT score comes from an ASVAB, but not every ASVAB subtest feeds the AFQT.
Can I see my line scores before I take the real test? Not officially before test day, but a well-built practice test that scores you by subtest lets you estimate them, since line scores are just specific combinations of subtest results you can calculate yourself once you know which subtests a given composite uses.
Does a high AFQT guarantee I get the job I want? No. AFQT determines whether you can enlist; the specific job you’re assigned depends on your line scores, medical qualification, background check, and current job availability in your target branch.
How is the AFQT different from a percentage score? An AFQT of 70 doesn’t mean you answered 70% of questions correctly. It means your combined performance on AR, MK, and VE matched or beat 70% of the 1997 reference sample. Two people with very different raw answer counts can land on the same percentile if the underlying subtests were weighted differently between them.
Do all four AFQT subtests count equally? No. Verbal Expression (Word Knowledge plus Paragraph Comprehension) is doubled in the formula, so it carries as much weight as Arithmetic Reasoning and Math Knowledge combined.
Bottom line: your AFQT is the enlistment gate, computed from four subtests with verbal weighted double; your line scores are separate combinations that decide which specific jobs you qualify for, so a strong AFQT and a strong line score for your target job are two different things to prepare for.
