Marines ASVAB Calculator
See every Marine Corps MOS you qualify for, plus the three line scores recruiters use to assign you a job.
The 3 Marine Line Score Formulas
Every Marine MOS has a minimum line score in one of these composites. Raise the right subtests and you unlock the fields you actually want.
GT, General Technical
= AR + VE
MM, Mechanical Maintenance
= AR + MC + AS + EI
EL, Electronics
= GS + AR + MK + EI
VE = Verbal Expression (WK + PC). The Marine Corps uses a focused subset of the standard line score composites, so improving WK and PC lifts your GT directly.
Line Score Requirements for 10 Popular Marine MOS
| MOS | Title | Line Score |
|---|---|---|
| 0311 | Rifleman | GT 80 |
| 0231 | Intelligence Specialist | GT 110 |
| 0321 | Reconnaissance Marine | GT 105 |
| 0211 | Counterintelligence/HUMINT | GT 110 |
| 0317 | Scout Sniper | GT 100 |
| 0331 | Machine Gunner | GT 80 |
| 0352 | Antitank Missile Gunner | GT 100 |
| 0313 | LAR Marine | GT 90 |
| 0341 | Mortarman | GT 80 |
| 0351 | Infantry Assault Marine | GT 100 |
The calculator above checks every Marine MOS we have data for, not just these. It also shows which ones you're close to qualifying for and which subtests would close the gap fastest.
Marines ASVAB FAQ
What's the minimum AFQT score to join the Marines?
31 with a high school diploma, 50 with a GED. Most Marine MOS gate on a line score (GT, MM, or EL) on top of the AFQT floor, so hitting just the minimum leaves your job options narrow.
What's the most important Marine line score?
GT (General Technical). It's the gatekeeper for the largest set of MOS, including the intelligence field (0211, 0231) and most technical and leadership tracks. If you're optimizing one score, optimize GT.
How is the Marine GT score calculated?
GT = AR + VE, where VE (Verbal Expression) = WK + PC. That means your verbal subtests and arithmetic reasoning drive GT. Raising WK or PC raises VE, which raises GT point for point.
Can I pick my MOS before enlisting?
The Marine Corps typically guarantees an occupational field rather than a single MOS. If you qualify on the line score, you can contract for a field; the exact MOS is often assigned during or after recruit training based on Corps needs.
What ASVAB score do Marine infantry MOS need?
Most ground combat MOS such as 0311 Rifleman require GT 80, while specialized infantry roles like Scout Sniper (0317) and Reconnaissance (0321) require GT 100-105. The calculator above flags which you qualify for.
