ASVAB Scores for Army Jobs: How Line Scores Set Your MOS

Two different scores: getting in vs. getting the job

People often talk about "the ASVAB score" as if it were one number. For the Army, it's really two things:

• Your AFQT, a percentile from 1 to 99, built from Arithmetic Reasoning (AR), Mathematics Knowledge (MK), and Verbal Expression (Word Knowledge + Paragraph Comprehension). This determines basic enlistment eligibility. For the Army with a high-school diploma, the minimum AFQT is roughly 31 (often around 50 for a GED). Learn more about how it's calculated on our AFQT scores page.
• Your line scores, branch-specific combinations of subtests that determine which MOSs you qualify for. A high AFQT gets you in the door; the right line scores open the specific job.

How the Army builds line scores

The Army takes your standard scores from the nine ASVAB subtests and adds them into ten composite "line scores." Each line score maps to a family of jobs. You don't take a separate test for these, they're computed automatically from the same ASVAB you already sat for. The subtests involved are General Science (GS), Arithmetic Reasoning (AR), Word Knowledge (WK), Paragraph Comprehension (PC), Mathematics Knowledge (MK), Electronics Information (EI), Auto & Shop Information (AS), Mechanical Comprehension (MC), and Assembling Objects (AO).

The ten Army line scores

*Some older composites reference a Coding Speed (CS) subtest; the current ASVAB no longer includes it, so today's line scores are computed from the nine subtests above. Treat this table as a guide to the type of subtests each line rewards, not a promise of exact formulas.

What different line scores open up

Here's the practical takeaway: the subtests you're strong in steer you toward whole categories of Army work.

• Strong verbal + reasoning (GT)? A high GT score is one of the most valuable numbers in the Army. It's often the gate for intelligence, military police, and many leadership and warrant-officer paths. If you want doors open later, protect your GT.
• Strong in electronics and math (EL)? You're looking at signal, avionics, radar, and cyber-adjacent roles, technical fields with strong civilian crossover.
• Hands-on and mechanical (MM, GM)? Vehicle and equipment maintenance MOSs reward Auto & Shop, Mechanical Comprehension, and Assembling Objects.
• Science and broad aptitude (ST)? Skilled Technical is the pathway to many medical, engineering, and analyst jobs.

Because most MOSs list a minimum line score (commonly in the 90s–100s range on the standard-score scale), raising your weaker subtests can literally add jobs to your eligibility list.

How to study for the job you actually want

The smart move is to work backward: pick a target MOS (or a couple), find which line scores gate it, then study the subtests that feed those lines and the four AFQT subtests that get you in.

1. Lock in your AFQT first. AR, MK, WK, and PC drive enlistment eligibility, so they pay off twice, they raise your AFQT and feed most line scores.
2. Add the subtests your target line needs. Chasing electronics jobs? Put extra time on General Science and Electronics Information. Mechanical work? Auto & Shop and Mechanical Comprehension.
3. Practice the way the real test runs, timed, mixed subtests. Our how to study guide covers pacing and review methods.

Once you're in: your score keeps mattering

Getting the MOS is the start, not the finish. In the Army, your GT score can affect reclassification and schooling options down the road, and once you're serving in the enlisted ranks you'll start earning promotion points toward sergeant and staff sergeant. When that day comes, you can track exactly where you stand with our promotion points calculator. From your first score to your next stripe, it's one continuous climb.
