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.

The scores that decide job eligibility
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. The two numbers are not related, and reading a percentile as a percentage is the single most common ASVAB misunderstanding.
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
Roughly
30
Two standard deviations below the mean
About the 2nd percentile of the reference group
40
One standard deviation below
About the 16th percentile
50
The mean
About the 50th percentile
60
One standard deviation above
About the 84th percentile
70
Two standard deviations above
About the 98th percentile
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
Most published summaries collapse IVA, IVB and IVC into a single Category IV covering 10 to 30. Both presentations are correct; the finer breakdown is the one used in the technical literature, and it matters because the services treat the three sub-bands differently for enlistment purposes.
Where the categories sit against enlistment
Every service floor currently sits inside Category IIIB, and federal law limits how many Category IV recruits the services may accept. In practice that makes 31 the number most candidates are working toward as a minimum — but see the per-branch minimums, which differ, and what counts as a good score, which is a different question entirely.
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 composite distribution is slightly asymmetric in the reference sample. You can see this for yourself by setting every slider to the mean in the AFQT calculator.
Considering a service academy or ROTC?
West Point, the Naval Academy, the Air Force Academy and ROTC scholarships all take an SAT or ACT score, not the ASVAB. Our SAT course covers Reading & Writing and Math in full, with adaptive practice tests and instant scoring.
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 in the technical literature.
The AFQT tops out at 99, because the scale is a percentile and there is no 100th percentile by construction. A perfect performance on all four AFQT subtests still reports as 99.
PAY97 — Profile of American Youth, 1997 (ages 18–23). The reference group is fixed rather than recalculated each year, which is why AFQT scores from different decades are directly comparable.
Yes, and it usually looks that way. The subtest scores are on a mean-50 scale while the AFQT is a percentile, so the two are not comparable numbers at all. A set of subtest standard scores around 55 can produce an AFQT in the 60s or 70s.
