How the ASVAB is scored:
AFQT and line scores

The AFQT is a percentile, not a percentage

An AFQT of 60 does not mean you answered 60% correctly. It means you scored as well as or better than 60% of a reference group of test takers. This trips people up constantly, in both directions — a 50 is not a fail, and a 90 is not 90% right.

It comes from four subtests only, with the verbal half doubled: 2 × (Word Knowledge + Paragraph Comprehension) + Arithmetic Reasoning + Mathematics Knowledge.

Line scores decide the job

The other five subtests do not touch the AFQT. They combine into line scores — different services combine them differently — and those decide which military occupations you qualify for. Mechanical Comprehension and Electronics Information matter enormously for some roles and not at all for others.

So the honest order of operations is: the AFQT decides whether you get in, and the line scores decide what you do once you are.

What a good score is

It depends on the branch and on the year, because each service sets its own minimum and moves it with recruiting need. Anyone who gives you a single number as the passing score is telling you about one service, on one day. Ask your recruiter what the current minimum is for the branch and the job you want.

What our practice score tells you

Our exams report what you got right, subtest by subtest, and explain every wrong answer individually. What they deliberately do not do is invent an AFQT percentile — that would require the reference group the Department of Defense uses, which is not published. A practice score that claims to be your AFQT is guessing at it.
