Marine Corps jobs are called MOS (Military Occupational Specialties), and each one sets a minimum composite score built from your ASVAB subtests. Most infantry MOS require GT of 90 or higher, intelligence and cyber jobs require GT of 110 or higher, and technical fields key off EL, MM, or CL composites, usually between 90 and 105. Your AFQT gets you into the Corps, but these composites decide what you do once you are in.

How do you read USMC composite requirements?

The Marines use five main composites. Each is a sum of standard subtest scores, so a requirement like “GT ≥ 100” means your Verbal Expression plus Arithmetic Reasoning total must reach 100.

Composite Formula
GT (General Technical) VE + AR
CL (Clerical) VE + AR + MK
EL (Electronics) AR + MK + EI + GS
MM (Mechanical Maintenance) AR + AS + MC + EI
GM (General Maintenance) AR + MC + AS + EI

VE (Verbal Expression) combines Word Knowledge and Paragraph Comprehension. Arithmetic Reasoning appears in every composite, which makes it the single highest-leverage subtest for a future Marine.

What ASVAB scores do Marine Corps jobs require?

Here are 15 real USMC MOS with their composite minimums. Requirements shift over time, so confirm current numbers with a recruiter [NOTE: verify all minimums against the current MOS manual before publishing].

MOS Job title Minimum composite
3531 Motor Vehicle Operator MM ≥ 85
0311 Rifleman GT ≥ 90
0331 Machine Gunner GT ≥ 90
0811 Field Artillery Cannoneer GT ≥ 90
1141 Electrician EL ≥ 90
1371 Combat Engineer MM ≥ 95
0111 Administrative Specialist CL ≥ 100
0431 Logistics/Embarkation Specialist GT ≥ 100
5811 Military Police GT ≥ 100
0321 Reconnaissance Marine GT ≥ 105
0621 Transmissions Systems Operator EL ≥ 105
2161 Machinist MM ≥ 105
3432 Finance Technician CL ≥ 105
0231 Intelligence Specialist GT ≥ 110
0651 Cyber Network Operator GT ≥ 110

A few jobs are not open to new recruits at all. Critical Skills Operator (0372, MARSOC) and EOD Technician (2336) are lateral moves for Marines already serving, so no entry ASVAB line applies.

Which USMC jobs have the highest ASVAB bars?

The GT 110 tier is the ceiling for most enlisted entry jobs: Intelligence Specialist (0231), Counterintelligence/HUMINT Specialist (0211), Imagery Analysis Specialist (0241), Geospatial Intelligence Specialist (0261), and Cyber Network Operator (0651) all sit there. On the mechanical side, Machinist (2161) and Refrigeration and A/C Technician (1161) require MM of 105 or higher.

GT 110 matters beyond job selection. It is also the commonly cited line for programs like officer candidacy later in your career [NOTE: verify], so clearing it early keeps doors open.

How should you prepare for a specific MOS?

Find your target MOS in the table, note which composite it uses, then study the subtests inside that formula. Every path runs through Arithmetic Reasoning, so start there. A GT-focused Marine adds Word Knowledge and Paragraph Comprehension. An EL or MM candidate adds Mathematics Knowledge, Electronics Information, General Science, and the auto, shop, and mechanical subtests.

FAQ

What ASVAB score do I need for Marine Corps infantry?

Infantry MOS like Rifleman, Machine Gunner, and Mortarman require GT of 90 or higher. Reconnaissance Marine raises the bar to GT of 105 or higher.

What is the highest ASVAB requirement in the Marines?

For entry-level MOS, the GT 110 tier held by intelligence and cyber jobs is the top of the scale in this data. Some specialties add screening beyond the ASVAB, like security clearances and physical tests.

Can I switch to a higher-score MOS after joining?

Sometimes, through lateral moves, and a few jobs like MARSOC and EOD are only reachable that way. It is far easier to score well once and pick the job you want up front.

Do USMC MOS ASVAB scores change?

Yes. The Marine Corps updates its MOS manual regularly, and minimums move with the needs of the service. Treat any published table, including this one, as a starting point and confirm with a recruiter.
