ASVAB Scores for Marine Aviation MOS

Marine aviation splits into two very different score stories. Enlisted aviation support and maintenance paths usually live inside the ASVAB line-score world. Officer aviation shifts into the ASTB-E world. If you mix those two tracks together, you will end up studying for the wrong gate.

The enlisted aviation score map

Marine aviation on the enlisted side spans several occupational fields. Each one has its own technical focus, and the dominant line score shifts depending on whether the work is primarily electronics-driven or mechanical.

These are field-level patterns, not published minimums. The Marine Corps does not publicly release specific line-score cutoffs for each MOS, and what your recruiter sees at MEPS may differ from published guidance. The table above reflects the technical emphasis of each field, which is the most reliable signal for how to direct your study time.

The broader pattern is clear: technical aviation work in the Marine Corps leans hard on EL and MM. That is not a coincidence. These two composites are built from the exact subtests that mirror what aviation technicians actually do: reading circuits, applying mechanical advantage, working through math formulas, and diagnosing systems.

Why EL and MM matter: a subtest breakdown

Understanding what goes into each composite makes the study sequence obvious.

EL (Electronics Repair) = GS + AR + MK + EI

• EI (Electronics Information) tests your grasp of circuits, current, voltage, and basic electrical components. Think resistors, ohms, and how current flows through a series circuit.
• GS (General Science) covers physics concepts like force, energy, and measurement. Aviation electronics work requires that foundation constantly.
• MK (Mathematics Knowledge) is algebra-level math: solving for unknowns, working with formulas, and handling the kind of equation that shows up when calculating electrical load.
• AR (Arithmetic Reasoning) is word-problem math. It asks you to read a scenario and solve it, which mirrors real troubleshooting logic.

MM (Mechanical Maintenance) = AR + MC + AS + EI

• MC (Mechanical Comprehension) tests mechanical advantage, gears, pulleys, levers, and fluid dynamics. If you are going to work on aircraft systems that move or pressurize, MC is the core subtest.
• AS (Auto and Shop Information) covers tool use, vehicle systems, and basic shop knowledge. It is more hands-on in flavor than any other subtest.
• AR powers both composites. A strong AR score lifts both EL and MM at the same time, which is why most aviation applicants prioritize it first.
• EI also appears in both composites. Investing time in electronics fundamentals pays double dividends across the entire aviation score picture.

The overlap between EL and MM is intentional. Marine aviation maintenance requires both electrical understanding and mechanical intuition. A Marine diagnosing a hydraulic fault on a rotary-wing aircraft needs both skill sets, and the scoring structure reflects that reality.

The officer aviation exception: ASTB-E

If your goal is Marine officer aviation, stop planning around ASVAB line scores. The test that determines whether you enter pilot or flight officer training is the ASTB-E, not the ASVAB.

The ASTB-E is a separate battery with six subtests that produce aviation-specific scores including AQR (Aviation Qualification Rating), PFAR (Pilot Flight Aptitude Rating), and FOFAR (Flight Officer Flight Aptitude Rating). These are the numbers that matter for competitive selection into a Marine aviation pipeline. Your ASVAB AFQT score still needs to meet the minimum threshold if you accessed through an NROTC scholarship, but once you are competing for aviation selection itself, the ASTB-E is the gate.

The clean rule: enlisted aviation support starts with ASVAB line scores; officer aviation starts with ASTB-E.

Study sequence and margin thinking

For enlisted aviation applicants, the subtest priority order follows the composite math directly.

Start with AR because fixing it lifts your score in two composites at once. Move to MK next because algebra fluency is the foundation for EI work. Then invest in EI before MC because EI multiplies across both composites the same way AR does.

Scoring at or just above a published minimum is a fragile position. Aviation maintenance fields attract competitive applicants, and a recruiter working a tight quota may have several candidates to choose from. Aiming 10-15 points above any minimum you can identify is not excessive. It builds in room for a bad test day and keeps your options open if your first-choice MOS has no seats when you get to MEPS.

That margin also matters for reenlistment. Marines who want to lateral move into a more competitive aviation MOS later in their career often need to demonstrate scores that satisfy that MOS’s requirements. Leaving yourself headroom on day one means you are not locked out of future moves.

Fallback planning if your first choice is closed

Aviation MOS slots close and open based on needs of the Marine Corps, not your timeline. If the specific field you targeted is unavailable at MEPS, the line scores you built for aviation can still open other doors.

GT (General Technical) = VE + AR + MC is the fallback composite that covers the widest range of Marine jobs outside aviation. A strong GT score keeps infantry, intelligence, communications, and a range of other technical fields accessible while you wait for an aviation billet to open, or if your priorities change before you ship.

The strategic move is to build EL and MM deliberately and let GT come along for the ride. AR and MC both appear in GT, so a study plan centered on the aviation composites will naturally produce a usable GT score. You do not need to study for GT separately if you are already targeting aviation line scores. The overlap does that work.

CL (Clerical) = VE + MK is less relevant for aviation but can keep administrative and finance options open if life circumstances shift. It does not take dedicated study for most applicants. It follows naturally from strong MK and vocabulary work.

The trap is hyper-specializing your prep for a single MOS with no fallback built in. A recruiter can only put you in a job the Marine Corps currently has available. Broader scores keep you in control of the conversation.

If you are still sorting out which specific fields or MOS numbers fit your goals, the ASVAB test prep guide covers score strategy and study resources in detail.

Aviation MOS school and training pipeline

Marine aviation technicians attend MOS school after completing Boot Camp at Marine Corps Recruit Depot Parris Island or San Diego. The length and location of MOS school vary by field. Aircraft maintenance Marines in fields 60, 61, and 62 typically attend training at Naval Air Station Pensacola or other Navy training commands, where they learn platform-specific maintenance procedures on actual airframes.

Avionics Marines in fields 63 and 64 attend electronics-focused training that covers aircraft communication systems, navigation equipment, and weapons system electronics. Aviation ordnance Marines in field 65 train on weapons handling, loading procedures, and safety protocols for aircraft-delivered munitions. Airfield services Marines in field 70 may train at multiple locations depending on their specific MOS, with some attending crash-fire-rescue schools and others attending fuels or airfield operations courses.

The training pipeline for aviation MOSs is longer than many ground MOSs. A Marine entering field 61 or 62 can expect Boot Camp followed by MOS school that runs several months, depending on the specific airframe they are assigned to. F/A-18 maintainers, CH-53 maintainers, and MV-22 maintainers all follow different schoolhouse tracks because the systems they will work on are fundamentally different. This extended pipeline is one reason aviation fields tend to attract applicants who prepared their scores deliberately rather than accepted whatever contract was available on test day.

How to read your ASVAB results for aviation planning

When your results come back from MEPS, the numbers that matter most for aviation planning are EL and MM. Your AFQT tells you whether you cleared the enlistment gate. EL and MM tell you which aviation fields are actually accessible.

If EL came back strong and MM is soft, your options lean toward command and control and logistics aviation support rather than hands-on maintenance. If MM is strong and EL is soft, the mechanical and ordnance side of aviation is accessible but technical avionics and electronics work may be limited. The best aviation profile keeps both composites strong enough that the recruiter is not steering you around closed doors from the start.

Your ASVAB score stays on file. Marines who retest after a low score follow a defined timeline, the first retest window opens after 30 days, and a critical-gain confirmation test applies if the score jumps 20 or more points within a 6-month window. Read Marine ASVAB Retesting Rules and Timeline before you schedule a retest so the calendar does not catch you off-guard.
