The Short Answer
The ASVAB is not pass/fail. It produces two kinds of score. Your AFQT — built from only four of the subtests — is a percentile from 1 to 99 that decides whether you can enlist at all. Your line scores — combinations of all the subtests, calculated differently by each branch — decide which jobs you qualify for. Most applicants take the CAT-ASVAB, a computer-adaptive version with 10 subtests and 135 scored questions, which takes about two hours on average.
| Item | Fact |
|---|---|
| Versions | CAT-ASVAB (computer, adaptive, at MEPS or a MET site), paper-and-pencil (some MET sites), PiCAT (unproctored, at home, first-timers only) |
| Subtests | 10 on the CAT-ASVAB |
| AFQT subtests | Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge, Paragraph Comprehension |
| AFQT scale | Percentile, 1–99, against a national sample of 18–23-year-olds |
| Passing score | None. Category V (1–9) cannot enlist by law; each branch sets its own minimum above that |
| Retest | Wait 1 month, then 1 month, then 6 months between every further retest |
Our free ASVAB practice questions cover the AFQT subtests and the technical ones, with a worked explanation for every answer; the practice quiz gives you a timed set to start with.
The 10 Subtests: Questions and Time Limits
These are the official CAT-ASVAB figures for scored questions and time without tryout items. Some test-takers get extra, unscored tryout questions mixed in; when that happens the subtest is longer and the time limit is extended to match, and you cannot tell which questions are tryouts.
| Subtest | Scored questions | Time limit (minutes) | In the AFQT? |
|---|---|---|---|
| General Science (GS) | 15 | 12 | No |
| Arithmetic Reasoning (AR) | 15 | 55 | Yes |
| Word Knowledge (WK) | 15 | 9 | Yes |
| Paragraph Comprehension (PC) | 10 | 27 | Yes |
| Mathematics Knowledge (MK) | 15 | 31 | Yes |
| Electronics Information (EI) | 15 | 10 | No |
| Auto Information (AI) | 10 | 7 | No |
| Shop Information (SI) | 10 | 6 | No |
| Mechanical Comprehension (MC) | 15 | 22 | No |
| Assembling Objects (AO) | 15 | 18 | No |
Two things follow from the table. First, the time is generous for math and tight for vocabulary: nearly a minute a question in Word Knowledge would be comfortable, but you have 36 seconds. Second, the AFQT subtests are only four of the ten — so for enlistment, most of your study time belongs on arithmetic word problems, algebra and geometry basics, vocabulary and reading.
How the AFQT Is Calculated
Word Knowledge and Paragraph Comprehension are combined into a Verbal Expression (VE) score. The raw AFQT is then 2 × VE + AR + MK — verbal ability counts double — and that figure is converted into a percentile. A percentile is not a percentage correct: an AFQT of 50 means you scored at or above half of the national reference group, not that you answered half the questions right.
| AFQT category | Percentile | What it usually means |
|---|---|---|
| I | 93–99 | Top scorers; widest job choice |
| II | 65–92 | Above average |
| IIIA | 50–64 | Average and above; the range recruiters prefer |
| IIIB | 31–49 | Eligible in most branches for diploma holders |
| IVA–IVC | 10–30 | Enlistment limited and often not possible |
| V | 1–9 | Not eligible to enlist (10 U.S.C. §520) |
Above Category V, each branch sets its own minimum AFQT. The minimums are higher for applicants with a GED or other high-school equivalency than for diploma holders, and they move with recruiting needs, so treat any number you read online as a guide and confirm it with a recruiter for the branch you want. A score comfortably above the minimum also matters for the job you get: line scores, not the AFQT, decide job eligibility, and the technical subtests feed into them.
CAT-ASVAB, Paper and PiCAT
- CAT-ASVAB — taken at a Military Entrance Processing Station (MEPS) or a Military Entrance Test (MET) site. Scores are available as soon as you finish.
- Paper-and-pencil — used at some MET sites and for the student version in high schools. Every examinee gets the same questions, you can go back within a subtest, and the whole session, with instructions, runs 3 to 4 hours. Scores take a few days.
- PiCAT — an unproctored CAT at home, available only if you have never taken the ASVAB. A recruiter gives you an access code that expires after 30 days; once you start you have 48 hours to finish. You then take a 25–30-minute proctored verification test within 45 days; if it confirms your result, the PiCAT becomes your score of record. You can take the PiCAT only once.
Retesting
After your first ASVAB you must wait one calendar month to retest, another month before a second retest, and then six months before each retest after that. The same rule applies whether your first test was the student version or an enlistment test. If your AFQT jumps by 20 points or more within six months, you will be asked to take a confirmation test to verify the gain. Your most recent valid score is the one that counts, so retest only when your practice scores show you are ready.
A Study Plan That Moves the AFQT
- Take a baseline in the four AFQT subtests. Your weakest of AR, MK, WK and PC is where the fastest gains are — and because verbal counts double, a weak WK/PC costs twice as much.
- Arithmetic Reasoning: drill word problems by type — rates and distance, percentages, ratios, averages, simple interest, work problems. Write the equation before you calculate; most misses are set-up errors, not arithmetic.
- Mathematics Knowledge: review fractions and exponents, solving linear equations, factoring, area and perimeter, the Pythagorean theorem and angle rules. No calculator is allowed.
- Word Knowledge: learn roots, prefixes and suffixes rather than word lists — they unlock unfamiliar words — and read daily. Practise at 36 seconds a question.
- Paragraph Comprehension: answer from the passage, not from what you know. The distractors are usually true statements the passage does not say.
- Technical subtests last, and only if the job you want uses them — mechanical and electronics line scores for maintenance and technical ratings, for example.
Use full ASVAB practice sets once a week to measure progress; between them, drill single subtests. The explanations show the set-up for every math problem, which is where most points are recovered.
Frequently Asked Questions
What is a passing score on the ASVAB?
There is no passing score. The AFQT percentile (1–99) determines whether you can enlist: Category V (1–9) is barred by law, and each branch sets its own minimum above that — higher for GED holders. Confirm the current minimum with a recruiter.
How many questions are on the ASVAB?
The CAT-ASVAB has 135 scored questions across 10 subtests. Some examinees also receive unscored tryout questions, which lengthen the subtest and extend its time limit.
How long does the ASVAB take?
About two hours on average for the CAT-ASVAB. The paper version, with instructions and administration, takes 3 to 4 hours.
Which ASVAB subtests count toward the AFQT?
Four: Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension. Word Knowledge and Paragraph Comprehension form the Verbal Expression score, which is counted twice.
How soon can I retake the ASVAB?
One month after the first test, one month after the second, and six months between any further retests.
Can I use a calculator on the ASVAB?
No. Scratch paper and pencils are provided; all calculations are done by hand.
