ASVAB Line Scores: Every Army Composite Formula Explained
How composite scores are built and why they decide your job, not your AFQT
July 3, 2026
ASVAB line scores, also called composite scores, are sums of your subtest standard scores that each branch uses to qualify you for specific jobs. The Army builds ten named composites, from CL (Clerical) to ST (Skilled Technical), and every Army job posts its requirements against them. Your AFQT decides whether you can enlist, but line scores decide what you can do once you are in.
How are line scores calculated?
Each ASVAB subtest produces a standard score with a mean of 50 and a standard deviation of 10. A line score adds several of those standard scores together according to a branch formula, so a composite built from four subtests centers around 200 and job cutoffs typically land between about 85 and 120 depending on how the branch scales them. You never calculate these yourself on test day; the score report does it, but knowing the formulas tells you which subtests to study for the job you want.
One code confuses almost everyone: VE. Verbal Expression is not a subtest you sit for. It is a combined score built from Word Knowledge (WK) and Paragraph Comprehension (PC), and it appears in more composite formulas than any single subtest.
What are the Army line score formulas?
Here is the full Army table. GS is General Science, AR is Arithmetic Reasoning, MK is Mathematics Knowledge, MC is Mechanical Comprehension, EI is Electronics Information, AS is Auto and Shop Information, NO is Numerical Operations, and CS is Coding Speed.
| Code | Line score | Formula |
|---|---|---|
| CL | Clerical | VE + AR + MK |
| CO | Combat | AR + CS + AS + MC |
| EL | Electronics | GS + AR + MK + EI |
| FA | Field Artillery | AR + CS + MK + MC |
| GM | General Maintenance | GS + AS + MK + EI |
| GT | General Technical | VE + AR |
| MM | Mechanical Maintenance | NO + AS + MC + EI |
| OF | Operators and Food | VE + NO + AS + MC |
| SC | Surveillance and Communications | VE + AR + AS + MC |
| ST | Skilled Technical | GS + VE + MK + MC |
Note that Numerical Operations and Coding Speed have been phased out of the test itself, so composites that reference them are computed with substitute values or revised formulas [NOTE: verify current treatment of NO and CS in Army composites].
What do real job requirements look like?
Army jobs list one or more line score minimums, and you must meet every listed composite to qualify. Three examples from current Army MOS requirements:
| MOS | Job | Line score requirement |
|---|---|---|
| 68W | Combat Medic Specialist | ST 101 and GT 107 or higher |
| 17C | Cyber Operations Specialist | GT 110 and ST 112 or higher |
| 42A | Human Resources Specialist | GT 100 and CL 90 or higher |
Look at what those formulas share. ST and GT both include VE, and CL and GT both include AR. A recruit who lifts Word Knowledge, Paragraph Comprehension, and Arithmetic Reasoning moves several composites at once, along with the AFQT. That overlap is the single most useful fact in ASVAB prep.
Do other branches use the same line scores?
No, and the names change even when the math is similar. The Air Force uses four MAGE composites: General (VE + AR), Administrative (VE + MK), Electronics (AR + MK + EI + GS), and Mechanical (MC + GS + 2AS). The Marine Corps uses composites like GT (VE + AR), EL, CL, and MM with its own formulas. The Navy and Coast Guard skip named composites for most ratings and instead list required subtest combinations directly, such as AR + MK + EI + GS for many technical ratings. If you are comparing branches, compare the subtests behind the requirement rather than the code letters.
How do you raise a specific line score?
Work the formula backward. Pick the job, read its required composites, and list the subtests inside them. Then drill those subtests specifically instead of studying the whole battery evenly. Someone chasing 68W should be living in science, verbal, math knowledge, and mechanical comprehension, because ST is GS + VE + MK + MC and GT is VE + AR.
ASVABDRILL is an ASVAB practice test platform focused on AFQT improvement, built for military recruits, covering ASVAB, PiCAT, and verification-style practice. Subject-level practice there maps cleanly onto composite prep, since every line score is just a bundle of subtests you can drill one at a time.
FAQ
What is the difference between a line score and a composite score?
Nothing. The terms are interchangeable. The Army usually says line scores, other branches and official documents often say composites or aptitude area scores.
What is a good line score?
It depends entirely on the job. Requirements in the Army run from the high 80s for some combat and maintenance roles up to 110 or more for cyber, intelligence, and special operations pipelines. Aim a comfortable margin above the published cutoff for your target MOS.
Does the AFQT affect my line scores?
Not directly, but they share ingredients. The AFQT is built from AR, MK, WK, and PC, and those same four subtests appear throughout the composite formulas, so improving them raises both at once.
Where do I find my line scores?
They print on your official score report, and your recruiter can pull them any time. Practice platforms can estimate them from subtest performance, but the official numbers come from your real test.
