1ASVAB Requirements for the Marine Corps
The United States Marine Corps has specific ASVAB requirements that all applicants must meet. The ASVAB (Armed Services Vocational Aptitude Battery) is a standardized test that measures your abilities in various academic and vocational areas. Your scores determine both your eligibility to enlist and which Military Occupational Specialties (MOS) you qualify for.
Marine Corps ASVAB Quick Facts
Minimum Requirements
- AFQT Score: 32 or higher (31 with GED)
- Age: 17-28 years old
- Education: High school diploma or GED
- Citizenship: U.S. citizen or legal permanent resident
Competitive Score Ranges
- 50+: Qualifies for most MOS options
- 65+: Opens technical and specialized jobs
- 80+: Maximum job selection and bonuses
- 110+ GT: Required for officer programs
The Marine Corps is known for being selective. While the minimum AFQT score is 32, many Marine Corps recruiters prefer candidates with scores of 50 or higher because these applicants have more MOS options available and are generally easier to place in positions that match their abilities and the Corps' needs.
Important Note About GED Holders
If you have a GED instead of a traditional high school diploma, you'll need to score at least 50 on the AFQT to enlist in the Marine Corps in most cases. The Corps has limited slots for Tier 2 (GED) applicants each year, so a higher score significantly improves your chances of acceptance.
2Understanding the AFQT Score for Marines
The AFQT (Armed Forces Qualification Test) score is the most critical number from your ASVAB results. This percentile score (1-99) determines whether you can enlist in any branch of the military, including the Marine Corps.
How the AFQT Score is Calculated
Your AFQT score is derived from four ASVAB subtests:
Formula: AFQT = AR + MK + (2 × VE), where VE (Verbal Expression) is calculated from WK and PC scores.
AFQT Categories and What They Mean
For Marine Corps: Category IIIB (32-49) is the minimum for high school graduates. Categories I-IIIA (50+) give you the most MOS options and potential enlistment bonuses.
Understanding your AFQT score helps you set realistic goals for your ASVAB practice test preparation. If you're aiming for a technical MOS in the Marines, targeting a score of 50 or higher will give you the best selection of career options.
3Marine Corps Line Scores Explained
While the AFQT determines enlistment eligibility, your line scores determine which MOS (Military Occupational Specialty) you qualify for. The Marine Corps uses three primary composite scores, each calculated from different combinations of ASVAB subtests.
GT (General Technical)
The most widely used line score in the Marine Corps. Required for administrative, intelligence, and many technical positions.
Formula: GT = VE + AR
Subtests: Verbal Expression (Word Knowledge + Paragraph Comprehension) + Arithmetic Reasoning
MM (Mechanical Maintenance)
Used for vehicle mechanics, aviation maintenance, and equipment repair positions.
Formula: MM = NO + AS + MC + EI
Subtests: Numerical Operations + Auto & Shop + Mechanical Comprehension + Electronics Information
EL (Electronics)
Required for communications, radar, electronics repair, and cyber-related positions.
Formula: EL = GS + AR + MK + EI
Subtests: General Science + Arithmetic Reasoning + Mathematics Knowledge + Electronics Information
Why GT Score Matters Most
The GT (General Technical) score is arguably the most important line score for Marine Corps applicants because:
- It's required for the widest range of MOS options
- A GT of 110+ is required for officer candidate programs
- Higher GT scores open doors to intelligence and cyber specialties
- Many promotion opportunities favor Marines with higher GT scores
4Popular Marine MOS and Score Requirements
The Marine Corps offers over 180 different Military Occupational Specialties. Here are some of the most popular options and their ASVAB score requirements. Use this as a guide when setting your ASVAB practice test goals.

5Study Strategies for Marine Corps Applicants
Preparing for the ASVAB as a future Marine requires a strategic approach. Here are proven methods to maximize your score and qualify for your desired MOS.
Focus on AFQT Subtests First
Your AFQT score gates everything else. Prioritize Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge, and Paragraph Comprehension. Without a qualifying AFQT, nothing else matters.
Study Split: Spend 60-70% of your time on AFQT subtests, 30-40% on technical subtests relevant to your target MOS.
Build Vocabulary Daily
Word Knowledge is one of the highest-yield subtests to improve. Learn 10-15 new words daily. Focus on roots, prefixes, and suffixes to decode unfamiliar words on test day.
Pro Tip: Create flashcards with the word on one side and definition + example sentence on the other.
Master Mental Math
Calculators aren't allowed on the ASVAB. Practice doing arithmetic by hand until it becomes second nature. Focus on multiplication tables, fraction operations, and percentage calculations.
Key Skills: Times tables through 12, converting fractions to decimals, calculating percentages, basic algebraic operations.
Practice Under Timed Conditions
The ASVAB is timed, and many people run out of time. After you've learned the content, practice with a timer. Aim to answer each question in about 1 minute on average.
Strategy: If stuck on a question for more than 90 seconds, make your best guess and move on. You can return to it if time permits.

About Retaking the ASVAB
If you're not satisfied with your initial score, you can retake the ASVAB after 30 days. A second retest requires waiting another 30 days. After that, you must wait 6 months between retests. Your most recent score is the one that counts for enlistment, so only retake if you're confident you'll improve.
8Frequently Asked Questions
What is the minimum ASVAB score for the Marines?
The Marine Corps requires a minimum AFQT score of 32 for high school diploma holders. GED holders typically need a score of 50 or higher. However, scoring higher opens more MOS options and may qualify you for enlistment bonuses.
How long is the ASVAB valid for Marine Corps enlistment?
ASVAB scores are valid for 2 years from the test date. If your scores expire before you enlist, you'll need to retake the test. This gives you time to complete other enlistment requirements like medical screening and background checks.
What GT score do I need for Marine Corps officer programs?
Most Marine Corps officer programs require a minimum GT score of 110. Competitive programs like aviation or intelligence may prefer scores of 115 or higher. The Officer Candidate School (OCS) application also considers your overall academic record and leadership experience.
Can I choose my MOS in the Marines?
Unlike some branches, the Marine Corps uses a "contract first" approach where you enlist into a Program Enlisted For (PEF) that groups related MOS options. Your specific MOS is assigned during or after boot camp based on your ASVAB scores, performance, and the needs of the Corps.
How many times can I take the ASVAB?
There's no lifetime limit on ASVAB attempts. You can retake it after 30 days for your first retest, another 30 days for your second, and then every 6 months thereafter. However, your most recent score is the one used for enlistment, so only retake if you're confident you'll improve.
Is the ASVAB practice test the same as the real test?
ASVAB practice tests use similar question types and difficulty levels as the actual exam, but the specific questions are different. Practice tests help you understand the format, identify weak areas, and build test-taking stamina. Our ASVAB practice test for Marines covers all the key subtests you need for a strong AFQT and GT score.
