What is a GT score on the ASVAB?

If you are already in the Army, or aiming at a job or school that needs one, the letters you keep hearing are GT. It is a line score, not the AFQT, and it is the number the Army's own career-advancement material talks about. Here is what the Army says about it — and, just as importantly, what it does not say.

A GT score is a line score, not the AFQT

The AFQT is the enlistment percentile, reported from 1 to 99: how the ASVAB is scored covers where it comes from, and the score chart lays out its categories. A GT score is a different number on the same report — one of the Army's line scores, the composites that decide which military occupational specialties and which schools are open to you (line scores explained).

The quickest way to see that the two are different scales: the Army's own articles about GT scores treat 100 and 110 as the numbers that matter. The AFQT cannot produce either one — it stops at 99. Whatever a GT score is measured in, it is not the enlistment percentile.

What the Army uses GT scores for

The Army's own article about soldiers raising their GT scores is direct about the stakes: "The Army Green to Gold program, officer candidate school, switching military occupational specialty, attending professional military schools and becoming a warrant officer all require specific GT scores, usually at least 100." That is army.mil, 2010-04-01.

So a GT score is not decoration and not a comparison to your friends. It is the gate on the moves a soldier makes after the enlistment contract — commissioning programs, schools, and changing what you do.

What counts as a good GT score

The Army does not publish a band table for GT scores, but its own reporting gives two anchors, both from army.mil:

• "A good score is 110 or above," — a BSEP education counselor, quoted in a 2023-01-18 article about the program that helps soldiers raise theirs.
• "A score of at least 110 allows a Soldier to participate in almost any career advancement opportunity." — the 2010-04-01 article.

Read together, the two numbers do different work. 100 is the "usually at least" line for the named programs — Green to Gold, officer candidate school, a change of MOS, professional military schools, warrant officer. 110 is what the Army calls a good score, and the level it describes as opening almost any career advancement opportunity. A soldier at 104 is not shut out; a soldier at 96 should expect the list of options to be shorter.

How the Army helps soldiers raise a GT score

The same 2023 article describes what the remedial course actually works on: "We work with them on three general areas: word knowledge, paragraph comprehension, and arithmetic reasoning." Those three are the syllabus — Word Knowledge and its study guide, Paragraph Comprehension and its study guide, and Arithmetic Reasoning and its study guide.

The article also draws a line between two different scores: "ST scores include everything that is in the GT plus general science knowledge", so a soldier who needs one score rather than the other is working from a different list — the ST version adds General Science on top.

The Army does not publish the GT formula

Neither of the two articles this page is built on prints a formula for how a GT score is computed, and this page does not print one either. That is deliberate. The articles say what a GT score gates and which three areas the Army's own course works on when a soldier needs a higher one; a formula you cannot quote from the service's own page is a formula we do not print, for the same reason an unsourced blueprint weight renders as TBD elsewhere on this site. Anything that tells you "the GT score is exactly X plus Y" is repeating a recollection, not a published rule.

Is there a maximum GT score?

The Army pages this page is built on state no ceiling, and we do not print one. It is worth knowing where a number people quote as a maximum usually comes from: the one ASVAB scale with a published ceiling is the AFQT, which tops out at 99 — what the highest ASVAB score is covers that — and a GT score is not on that scale, which is the same reason a GT of 110 exists at all.

If you are not in the Army yet

You do not have a GT score before you enlist; the number that decides whether you can join is a different one, and the number that decides what you can do afterwards is the line scores. The Army names its category scores as the job determinant and does not publish the composites behind them (why, and what is published for other branches); the Army page covers the enlistment side.

What that means in practice is the same advice that holds for every branch: do not study only the four subtests that build the AFQT. The three areas the Army's own GT course works on — Word Knowledge, Paragraph Comprehension and Arithmetic Reasoning — are a defensible place to start, and the free ASVAB diagnostic shows you which of your subtests is costing you the most before you spend a term guessing.

The test is the same in every branch

There is one ASVAB. GT is the Army's way of reading part of your report; the report is the same wherever you take it. How the ASVAB is scored covers the whole of it, and the branch minimum table covers the enlistment bar each service sets.
