How many line scores does the Marine Corps use?

The Marine Corps uses five aptitude-area line scores: GT (General Technical), CL (Clerical), EL (Electronics), MM (Mechanical Maintenance), and ST (Skilled Technical). Each MOS lists the one composite it scores against; a few require two at once.

Can I change my MOS after enlisting in the Marines?

Yes, through a lateral move (lat move), but it takes time. Most lat moves happen after your first enlistment, typically 3-4 years in. Approval depends on your current MOS manning, the target MOS manning, your ASVAB line scores for the new MOS, and a command recommendation. Nothing is guaranteed.

USMC MOS List 2026: ASVAB Line Scores for All 129 Marine Corps Jobs

Q: What is the lowest ASVAB line score for a Marine Corps job?

The lowest line-score barrier on the chart is Motor Vehicle Operator (3531) at MM 85, with most entry infantry MOS (Rifleman 0311, Machine Gunner 0331, Mortarman 0341) right behind at GT 90. All sit on top of the AFQT floor of 32.

Q: What is a GT score in the Marine Corps?

GT (General Technical) = VE + AR, where VE (Verbal Expression) is itself Word Knowledge + Paragraph Comprehension. It is the single most important Marine Corps line score because more MOS gate on GT than on any other composite, including cyber, intelligence, MP, and most leadership paths.

Every Marine Corps enlisted job needs an AFQT of 32 to qualify (50 with a GED), then a line-score composite that ranges from MM 85 (3531) at the low end up to EL 115 for the electronics and avionics maintainers. The chart below lists the required ASVAB line score for all 129 enlisted MOS, sortable by score, occupational field, or AFQT.

Your recruiter hands you a list of MOS codes, and unless you already know what a 0651 does versus a 6531, that list is useless. This page turns it into one scannable Marine Corps ASVAB score chart so you can see what you qualify for today, what is one study block away, and which subtests buy you the most jobs.

Marine Corps ASVAB Score Chart: All 129 MOS and Required Line Scores

Every row comes from the same dataset the Marine Corps ASVAB calculator scores against, so the numbers here match what your recruiter computes. Sort by required line score to find the lowest-barrier MOS, or by community to compare jobs in the same occupational field. Two composites joined by · (for example 2651 at GT 110 · EL 110) mean both are required at once.

How Marine Corps ASVAB Scoring Works: AFQT vs Line Scores

A Cyber Network Operator needs a GT line score of 110. The maximum AFQT is 99. Both numbers come from the same ASVAB, and they do different jobs.

The AFQT is your percentile from VE + AR + MK and decides whether the Marine Corps will take you: 32 with a diploma, 50 with a GED. The line-score composite is a raw sum of standard subtest scores and decides which MOS you can hold once you are in.

The five Marine Corps line-score formulas

Bookmark this. You will reference it constantly when comparing MOS requirements above.

GT = VE + AR
CL = VE + AR + MK
EL = GS + AR + MK + EI
MM = AR + EI + MC + AS
ST = GS + VE + MK + MC

VE (Verbal Expression) is a combined standard score derived from Word Knowledge (WK) and Paragraph Comprehension (PC); it is not a separate subtest. The rest are individual subtests: AR (Arithmetic Reasoning), MK (Mathematics Knowledge), GS (General Science), EI (Electronics Information), MC (Mechanical Comprehension), and AS (Auto & Shop Information). GT gates the most MOS on this chart, so VE and AR are the highest-leverage areas to study.

Marine Corps Occupational Fields at a Glance

The 129 MOS split across roughly two dozen occupational fields. Use the chart above for exact numbers; the notes below show where the score barriers cluster so you can target the right field.

Infantry (03 series). The lowest GT minimums in the Corps: Rifleman (0311), Machine Gunner (0331), and Mortarman (0341) at GT 90. Elite paths run higher — Recon (0321) and MARSOC Critical Skills Operator (0372) need GT 105 plus a selection pipeline.
Cyber and communications (06, 17 series). Cyber Network Operator (0651) and Cyberspace Warfare Operator (1721) need GT 110 plus a clearance; the comms operators (0612/0621/0627/0631) read on EL 105.
Intelligence and SIGINT (02, 26 series). Most intel and cryptologic MOS need GT 105-110 and a TS/SCI clearance; the linguists add the DLAB. 2651 ISR Systems Engineer is the toughest, at GT 110 AND EL 110.
Aviation maintenance (60-62 series). The largest technical field, almost universally MM 105 for the airframe, powerplant, and structures mechanics; the avionics technicians (63/64 series) read on EL 105-110.
Ground and aviation electronics (28, 59 series). The highest barrier in the Corps at EL 115 — digital wideband, ground radio, calibration, and aviation radar/comm maintainers. Strong GS + AR + MK + EI is the only way in.
Admin, supply, and ops (30, 60, 70 series). The Clerical roles — Supply Admin (3043), Aircraft Maintenance Admin (6046), and Aviation Operations (7041) — score on CL, not GT. If your verbal and math are solid but mechanical and electronics lag, these are a strong fit.
Military Police and ordnance (21, 58 series). MP (5811) needs GT 100; ordnance repair runs MM 95-105, and EOD (2336) needs GT 110 plus one of the toughest training pipelines in the military.

Frequently Asked Questions

What is the minimum ASVAB score for the Marines?

The Marine Corps requires a minimum AFQT of 32 with a high school diploma (50 with a GED). AFQT is your entry ticket. Each MOS then has its own line-score composite that decides which job you can hold.

What is the lowest ASVAB line score for a Marine Corps job?

The lowest line-score barrier is Motor Vehicle Operator (3531) at MM 85, with the entry infantry MOS (Rifleman 0311, Machine Gunner 0331, Mortarman 0341) right behind at GT 90. All sit on top of the AFQT floor of 32.

What Marine MOS requires the highest ASVAB score?

The hardest enlisted MOS to qualify for are the ground- and aviation-electronics maintainers at EL 115 (Digital Wideband 2831, Calibration Technician 2871, and the 59xx aviation radar/comm techs). The toughest dual-composite MOS is 2651 ISR Systems Engineer, which needs GT 110 AND EL 110 at once.

What is a GT score in the Marine Corps?

GT (General Technical) = VE + AR, where VE is Word Knowledge + Paragraph Comprehension. It is the most important Marine Corps line score because more MOS gate on GT than on any other composite. Run your scores through the Marine Corps ASVAB calculator to see what you qualify for now.

What if my line score is too low for the MOS I want?

Retake the ASVAB after the 30-day wait, negotiate a different guaranteed MOS your scores already clear, or enlist and lat-move later. Most recruits who prep 4-6 extra weeks gain 10-15 AFQT points on retest. Never sign an open contract unless you genuinely do not care which MOS you get.
