An ASVAB score report carries several numbers on several different scales, and they are easy to confuse with each other. Here is what each one is, what range it runs over, and what it is compared against.

Read the label before the number. Find your AFQT percentile for enlistment requirements, your named line scores for job requirements, and your individual subtest scores to identify subjects to review. A percentage from a practice quiz is a separate measurement.

An AFQT of 65 is not 65% of questions correct. It means you performed as well as or better than 65% of the reference group. A fixed practice quiz’s percentage correct cannot be substituted for that percentile.
Subtest standard scores
Each subtest is reported on a scale with a mean of 50 and a standard deviation of 10. That makes the numbers easy to read once you know the convention: 50 is average, 60 is a standard deviation above it, 40 a standard deviation below.
Reading a subtest standard score
Standard score
Position on this scale
30
Two standard deviations below the mean
40
One standard deviation below
50
The mean
60
One standard deviation above
70
Two standard deviations above
The official standard-score guide explains this mean and standard deviation. This table describes subtest scores; it is not an AFQT conversion table.
Unlike the old 1980 scale, current standard scores are not truncated at 20 and 80, so values outside that window are possible — they are simply rare.
AFQT categories
The Services divide the AFQT percentile range into categories, which appear throughout recruiting policy and in Congressional reporting on recruit quality. Category III is split into IIIA and IIIB at the median, and Category IV is split three ways.
AFQT categories
Category
Percentile range
I
93–99
II
65–92
IIIA
50–64
IIIB
31–49
IVA
21–30
IVB
16–20
IVC
10–15
V
1–9
Some summaries combine IVA, IVB and IVC into Category IV, covering 10–30. The official applicant score guide shows the full breakdown above. These are reporting categories, not job assignments.
Where the categories sit against enlistment
Requirements depend on the Service and your application circumstances. Use the branch reference table to start the conversation, then confirm current requirements with a recruiter. The score-goal guide explains how to connect your report with a specific route or job.
Why an average profile scores 48
If every one of your four AFQT subtests came in at exactly 50, your AFQT composite would be 200, and the official table converts that to 48 — not 50. The conversion is a lookup on a separate scale; a standard score of 50 is not itself an AFQT percentile of 50. Explore this by setting every slider to the mean in the AFQT calculator.
Frequently Asked Questions
There are two different ranges. The AFQT is a percentile from 1 to 99. Each individual subtest is a standard score with a mean of 50 and a standard deviation of 10, typically falling between about 20 and 80. There is no single "ASVAB score out of 100".
No, and this is the most common misreading of an ASVAB score. An AFQT of 65 does not mean you answered 65% of questions correctly. It means you scored as well as or better than 65% of a fixed national reference group.
Bands of the percentile range used across the Services for reporting and policy: Category I is 93 to 99, II is 65 to 92, IIIA is 50 to 64, IIIB is 31 to 49, IV is 10 to 30 and V is 1 to 9. Category IV is further divided into IVA, IVB and IVC on the official ASVAB score table.
The highest reported AFQT percentile is 99. That is the upper end of the official reporting scale, not a claim that you answered 99% of questions correctly.
PAY97 — Profile of American Youth, 1997 (ages 18–23). Your percentile compares performance with this national reference sample, not just the people testing at your site or during the current recruiting year.
Yes. Subtest standard scores and AFQT percentiles use different scales. Compare each score with its own definition and reference rather than deciding that the numerically larger one represents a stronger skill.
