ASVAB Line Scores for Marine Aviation MOS (60-73)
The best Marine aviation ASVAB profile is not a vague “good overall score.” It is a technical score profile built around EL and MM. If you are chasing enlisted aviation support, maintenance, avionics, ordnance, or airfield work, those are the two composites to respect first.

What “best” means for aviation fields
Most ASVAB coverage talks about line scores as if each one is independent. For aviation fields, that framing misses the point.
The composites that matter most are:
- EL (Electronics Repair): GS + AR + MK + EI
- MM (Mechanical Maintenance): AR + MC + AS + EI
Look at that math carefully. AR (Arithmetic Reasoning) and EI (Electronics Information) appear in both composites. That is the core insight. Studying AR and EI builds both scores at the same time, not one in isolation. A well-targeted study plan attacks those two subtests first, and the rest of the plan fills in around them.
The best aviation score profile is EL and MM together, not one alone. A candidate strong in EL but weak in MM may qualify for electronics-heavy avionics roles but struggle with mechanical maintenance and ordnance tracks. Carrying both composites gives you a wider range of aviation fields to choose from and more room to negotiate field assignments.
That is different from overbuilding CL (Clerical) or even GT (General Technical), which help in administrative and leadership contexts but do not directly serve the technical aviation community.
Aviation field breakdown by composite
Marine Corps enlisted aviation spans several occupational fields, each with a different technical emphasis. The composite that tends to be primary shifts depending on what the field actually does.
| OccFld | Field name | Primary composite | What the work involves |
|---|---|---|---|
| 60 | Aircraft Maintenance (general) | MM | Support equipment, flight gear, maintenance administration |
| 61 | Rotary-Wing Aircraft Maintenance | MM | Helicopter airframes, power plants, hydraulics |
| 62 | Fixed-Wing Aircraft Maintenance | MM | Fixed-wing airframes, engines, structural systems |
| 63 | Organizational Avionics Maintenance | EL | Aircraft electronics, navigation, comms at unit level |
| 64 | Intermediate Avionics Maintenance | EL | Calibration, repair, and testing of avionics components |
| 65 | Aviation Ordnance | MM | Weapons systems, loading, arming, maintenance |
| 70 | Airfield Services | MM / EL mix | Ground support, crash-fire-rescue, fuels, airfield ops |
| 72-73 | Aviation C2 and UAS | EL | Command-and-control electronics, UAS ground support |
Fields 63 and 64 lean EL because the work is circuit boards, avionics units, and signal systems. Fields 61, 62, and 65 lean MM because the work is mechanical systems, fluid systems, and weapons hardware. Airfield services and aviation C2 sit in between.
The table shows why a split approach to studying pays off. If you push both EL and MM to strong levels, you stay competitive across almost every enlisted aviation field rather than one narrow corner.
The study sequence that builds both EL and MM
Most study guides organize by section in isolation. For aviation, a smarter plan sequences by which subtests serve both composites first.
| Subtest | Composites served | Why it matters for aviation |
|---|---|---|
| AR (Arithmetic Reasoning) | EL and MM | Found in both formulas. Study this first, period. |
| EI (Electronics Information) | EL and MM | Circuits, voltage, resistance. Shows up in both formulas and is the most testable electronics content. |
| MK (Mathematics Knowledge) | EL | Formulas, algebra, and number properties that support EL directly. |
| GS (General Science) | EL | Physics, basic science, and energy concepts that underpin EL questions. |
| MC (Mechanical Comprehension) | MM | Mechanical systems, gears, pulleys, levers. Core to MM and directly applicable to maintenance roles. |
| AS (Auto and Shop Information) | MM | Tools, vehicle systems, shop terminology. Rounds out MM alongside MC. |
The order matters. AR and EI are the highest-return investments because they contribute to both composites simultaneously. MK and GS extend EL. MC and AS extend MM. A candidate who runs this sequence covers both composites rather than accidentally drilling only one.
This is also the reason verbal-first study plans underperform for aviation. VE (Verbal Expression) and WK (Word Knowledge) feed GT and CL, not EL or MM. You can have strong verbal scores and still fall short on both aviation composites.
Officer aviation is the exception
If the goal is to fly as a Marine officer, the ASVAB is not the selection tool. The ASTB-E is used for Marine officer aviation applicants when program guidance requires it. The ASVAB will still factor into overall qualification, but no aviation MOS line score drives officer aviation selection the way EL and MM drive enlisted aviation assignments.
For the full picture of how the two paths split, read ASVAB Scores for Marine Aviation MOS. For the ASTB-E specifically, the ASTB-E prep guide covers the score types, subtests, and study approach that actually apply to officer pipelines.
The short version: if you want to fly, focus on the ASTB-E. If you want to work on, maintain, or support the aircraft, build EL and MM.
Why scoring above minimum matters for aviation
Meeting the minimum line score opens the door. It does not guarantee the assignment.
Aviation maintenance and avionics fields are among the most technically demanding in the enlisted community. Seats in specific platforms (F/A-18 airframes, CH-53 rotary wing, UAS avionics) are not unlimited. When applicants who meet the minimum are competing for limited slots, scores above the floor give recruiters more flexibility to place you where you want to go.
A candidate who clears the minimum by a narrow margin can still be competitive, but they have less room to negotiate if their first-choice field is full. Going 10 or more points above the line score minimum in both EL and MM puts you in a stronger position during field assignment conversations. It also leaves you with fallback options in adjacent fields if your top pick is temporarily closed.
There is a practical ceiling too. At some point, additional score improvement returns less marginal benefit. A score that comfortably clears the threshold for your target field and the adjacent fields is the real goal. The highest possible number in isolation is not the objective.
Study plan: 4-6 weeks for EL and MM
A focused plan does not need to be long. Six weeks is enough time to build both composites from a solid starting point.
| Week | Focus | Goal |
|---|---|---|
| Week 1 | AR diagnostic and fundamentals | Identify weak areas in arithmetic and number operations. Build a baseline. |
| Week 2 | MK and EI | Math Knowledge (formulas, algebra) and Electronics Information (circuits, voltage, resistance). Both feed EL. |
| Week 3 | MC and AS | Mechanical Comprehension and Auto and Shop. Both feed MM. This is the most hands-on material in the sequence. |
| Weeks 4-5 | Mixed practice sets and timed drills | Rotate through all six subtests in test conditions. Time each section. Identify which subtest still loses points. |
| Week 6 | Full test simulation | Simulate the full ASVAB under timed conditions. Review every wrong answer. Do not study new material. |
The key discipline in weeks 4-6 is not practicing what you already know. Find the weak subtest and drill it. A candidate who is strong in MC but shaky in EI should spend extra time on circuits and electronics in that window, not extra time on gears.
If six weeks is more time than you have, compress weeks 4-5 into one week and keep the full simulation in place. The final simulation matters because most test anxiety comes from not knowing what the full experience feels like, not from missing obscure content.
The ASVAB prep guide has practice resources and drill sets organized by subtest if you want structured materials to run alongside this sequence.
For the broader aviation score picture, including the enlisted versus officer split and how the ASTB-E gates officer aviation candidates separately, read ASVAB Scores for Marine Aviation MOS. If you want the full field-by-field map across all Marine jobs, ASVAB Scores for Every Marine MOS covers every occupational field with the same composite-first framing used here.
One logistics note: if your scores come back below target, the retest window opens 30 days after your initial test. Use that window deliberately. A candidate who shows up to a retest without a changed study approach is unlikely to change the outcome. The Marine ASVAB retesting guide covers the timeline rules and the confirmation test that applies if your score jumps significantly between attempts.
Aviation MOS school locations and pipeline length
Marine aviation technicians follow a longer training pipeline than most ground MOSs. After Boot Camp, enlisted aviation Marines ship to MOS school at various Navy and Marine Corps training commands. The exact location depends on the occupational field and the specific platform assignment.
Aircraft maintenance Marines in fields 61 and 62 attend platform-specific training on the airframes they will maintain throughout their career. A Marine assigned to F/A-18 maintenance trains on Hornet systems at a different schoolhouse than a Marine assigned to CH-53E or CH-53K heavy lift helicopters. MV-22 Osprey maintainers follow yet another track because the tiltrotor platform combines fixed-wing and rotary-wing systems that require separate training modules.
Avionics Marines in fields 63 and 64 attend electronics schools that cover aircraft communication systems, radar, navigation equipment, and electronic warfare suites. Aviation ordnance Marines in field 65 train on weapons loading, munitions handling, and aircraft armament systems. The pipeline for aviation ordnance is generally shorter than airframe or avionics maintenance, but it carries its own set of security and safety requirements that screen candidates during the assignment process.
The length of these pipelines matters for score planning. A Marine who enters aviation with scores that barely clear the minimum is more likely to receive a generic assignment rather than a platform-specific contract. Stronger EL and MM scores give you more negotiating room to request the airframe or field you actually want before you ship to MOS school.
