Short answer: a good ASVAB score is an AFQT that clears your branch's minimum with room to spare. With a high school diploma, that minimum is 31 for the Army, Marine Corps, Navy and Air Force, 32 for the Coast Guard and 36 for the Space Force. A 50 means you scored as well as or better than half of a national sample of young adults, and 65 or higher puts you in Category II. Past the minimum, higher scores open more jobs.
When people talk about their "ASVAB score," they almost always mean the AFQT, the Armed Forces Qualification Test score. It isn't a separate test. It's built from four of the ten ASVAB subtests, and it's the number that decides whether you can enlist at all. The other subtests come into play later, when you pick a job.
Your AFQT is a percentile, not a percent
An AFQT of 62 doesn't mean you got 62% of the questions right. It means you scored as well as or better than 62% of a nationally representative sample of 18 to 23 year olds who took the ASVAB in a 1997 norming study. Every AFQT is compared with that same group, so scores run from 1 to 99 and 50 sits exactly in the middle.
Drag the score below to see what that looks like. Each dot is one person out of 100 in that national sample.

Two things follow from this. First, you can't "ace" the AFQT: 99 is the ceiling no matter how many questions you get right. Second, small changes near the middle of the scale move you past a lot of people, because most of the sample is bunched there.
The categories recruiters talk about
Recruiters group AFQT scores into categories, and you'll hear them say things like "Cat IIIA" or "a Category I score." These are the official ranges:
| Category | AFQT percentile | What it means |
|---|---|---|
| I | 93-99 | Top 7% of the national sample |
| II | 65-92 | Well above the middle |
| IIIA | 50-64 | At or above the national median |
| IIIB | 31-49 | Below the median, at or above most branches' minimums |
| IVA, IVB, IVC | 10-30 | Below every published minimum; enlistment is limited by law |
| V | 1-9 | The bottom of the scale |
Category IV has a limit written into federal law: a service can take no more than 4 percent of its enlistees in a year from AFQT 10 to 30, unless the Secretary of Defense raises that cap, to 20 percent at most. Applicants without a high school diploma need at least 31 by law.
The minimums by branch
These are the lowest AFQT scores each branch publishes for applicants with a high school diploma, checked against each branch's own site or manual. They are floors, not targets. Recruiters can ask for more when there are more applicants than openings, and the most popular jobs and bonuses usually need more too.

So what counts as a good score?
It depends on what you want the score to do.
- To enlist at all: clear your branch's line. With a diploma that's 31 for the Army, Marine Corps, Navy and Air Force, 32 for the Coast Guard and 36 for the Space Force. With a GED, plan on at least 50 for the Air Force, Space Force and Marine Corps.
- To have options: 50 or higher (Categories I to IIIA) puts you ahead of the national median and well clear of the range the law caps. It's a sensible target if you're not sure yet which branch or job you want.
- For a specific job: the AFQT gets you in; your line scores pick the job. Each branch combines different subtests into the scores it uses for each job, so an aviation mechanic leans on Mechanical Comprehension and Auto and Shop, and an electronics job leans on Electronics Information and math. Ask a recruiter which scores your target job uses.
What moves your AFQT the most
The AFQT combines Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Word Knowledge (WK) and Paragraph Comprehension (PC). WK and PC are pooled into a verbal score that counts twice, so the composite is AR + MK + 2 × verbal before it's turned into a percentile.
AFQT = AR + MK + 2 × Verbal
That weighting tells you where to spend your time:
- Vocabulary and reading are half your AFQT. Ten to fifteen minutes of words and word roots a day pays off twice, and it's the easiest habit to keep.
- Math is the other half. Arithmetic Reasoning is word problems; Mathematics Knowledge is high-school algebra and geometry. Both reward method over memory, and neither allows a calculator. Our mental math shortcuts cover the patterns that come up most.
- The other six subtests don't touch your AFQT, but they decide which jobs you qualify for. If you want a technical job, don't skip them.
Check where you stand
Eight questions, two from each AFQT subtest, scored with the same weights. Eight questions can only give a rough read, but it shows which side of the line you're starting from and which subtest needs you most.

Estimated AFQT

The AFQT estimate is rough: it comes from the 8 Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension questions, weighted like the real AFQT. Practice scores from original questions, not official ASVAB scores. ASVAB Test is not affiliated with the U.S. Department of Defense.

A student scores 78, 85, 92 and 89 on four practice tests. What is the average score?
Show answer
Answer: C. 86
Add the scores: 78 + 85 + 92 + 89 = 344. Divide by the number of tests: 344 ÷ 4 = 86. An average is always the total divided by the count.

At the exchange you buy items costing $3.45, $2.80 and $6.25. You pay with a $20 bill. How much change should you get?
Show answer
Answer: A. $7.50
Add the purchases first: 3.45 + 2.80 + 6.25 = 12.50. Then subtract from the payment: 20.00 − 12.50 = 7.50. Lining up decimal points when adding prevents the most common slip.

Expand: (x + 3)(x + 2)
Show answer
Answer: B. x² + 5x + 6
FOIL: First x·x = x², Outer x·2 = 2x, Inner 3·x = 3x, Last 3·2 = 6. Combine: x² + 5x + 6. The middle term adds the constants; the last term multiplies them.

What is 3/4 ÷ 1/2?
Show answer
Answer: D. 1 1/2
Dividing by a fraction means multiplying by its reciprocal: 3/4 × 2/1 = 6/4 = 3/2 = 1 1/2. The 3/8 trap comes from multiplying instead of dividing.

Candid means truthful and direct, even when the truth is uncomfortable: a candid opinion. A 'candid photo' is honest in the same way, catching people as they really are.

A lensatic compass has three main parts: the cover, which protects the face and holds the sighting wire; the base, which contains the floating dial; and the lens bracket, used to read the dial while sighting an object. The floating dial is marked in both degrees and mils.
According to the passage, which part holds the sighting wire?
Show answer
Answer: C. The cover
The passage states the cover 'protects the face and holds the sighting wire.' Detail questions are answered word-for-word from the text, not from memory of similar tools.

Aluminum is endlessly recyclable: a can melted down today can be back on a shelf as a new can within sixty days, using about five percent of the energy required to smelt new metal from ore. No other common packaging material comes close to that efficiency.
Which title best fits the passage?
Show answer
Answer: D. Aluminum: The Champion of Recycling
The passage's one idea is aluminum's unmatched recycling efficiency. A best-title question is a main-idea question in disguise: the right title covers the whole passage, not one detail.

Quick answers
Is 50 a good ASVAB score?
Yes. An AFQT of 50 is the national median by design: you scored as well as or better than half of the national sample. It's Category IIIA, and it clears every branch's minimum for applicants with a diploma.
What's the highest ASVAB score you can get?
99. The AFQT is a percentile from 1 to 99, so even a perfect run tops out at 99. Your individual subtests are reported separately, as standard scores where about half of the national sample scores 50 or higher.
Can you join the military with an AFQT under 31?
Not under any branch's published minimum for diploma holders, which all start at 31. The Army's Future Soldier Preparatory Course can take applicants from 21 and works on raising their score before basic training.
How long are ASVAB scores good for?
Two years from the test date. After that, you test again to enlist.
