Coast Guard ASVAB Score: What You Need to Qualify in 2026

The Coast Guard enlisted 5,204 members in FY2025, the highest number since 1991. That sounds like growth, but it still means roughly 5,000 slots for the entire branch. Your coast guard asvab score determines whether you get one of those slots and which of the ~24 ratings (jobs) you can compete for.

Two gates stand between you and a Coast Guard career. Gate one: your AFQT score must meet the enlistment minimum. Gate two: your individual subtest scores must add up to the threshold for your target rating. This guide covers both gates, every rating's exact score requirement, and how to study if you're not there yet. If you already have your scores, plug them into our calculator to see what you qualify for.

Coast Guard AFQT Minimum: The First Gate

Every site you check quotes a different number. Some say 36. Others say 40. A few say 32. Here's why.

The Coast Guard historically required an AFQT of 40 for high school diploma holders, the highest minimum of any branch. That threshold dropped to 36, then further to 32 in November 2023 when the CG updated its recruiting instruction (COMDTINST 1100.2) to address recruiting shortfalls.

But the official floor and the practical floor are different things. With only ~42,000 active-duty personnel and ~5,200 annual enlistment slots, the Coast Guard can afford to be selective. Scoring a 32 technically qualifies you, but most accepted recruits score well above that. Your coast guard asvab score needs to stand out in a pool where recruiters have the luxury of choosing.

BranchDiploma MinimumGED Minimum
Army3150
Marines3250
Navy3550
Air Force3665
Coast Guard3250
Space Force3665

GED holders face a steeper climb. The Coast Guard requires an AFQT of at least 50 with a GED, and fewer than 5% of accepted recruits lack a high school diploma. If you have a GED, completing 15 college credit hours at a community college upgrades you to Tier 1 status, putting you on equal footing with diploma holders.

How Coast Guard Scoring Works (It's Different from Army and Marines)

If you've researched Army or Marines ASVAB requirements, you've seen named composite scores like GT, CL, and ST. The Coast Guard doesn't use those.

The Coast Guard (like the Navy) uses a simpler system: it adds up your standard scores from specific ASVAB subtests and compares the total against a threshold. No composite name, no formula conversion. Just a straight sum.

IT (Information Systems Technician) = AR + MK + EI + GS >= 171

Each ASVAB subtest produces a standard score with a mean around 50 and a standard deviation around 10. Scores typically range from 20 to 62. When a Coast Guard rating requires “171,” it means your scores on those specific subtests must add up to at least 171.

The one exception: when the Coast Guard references a GT score (primarily for officer programs), it uses the same formula as the Army.

GT = VE + AR

VE (Verbal Expression) combines your Word Knowledge and Paragraph Comprehension scores. So GT is really WK + PC + AR, just like the Army calculates it.

This matters because you need to know which specific subtests feed each rating requirement, not just a composite name. Our line score calculator and GT score calculator can help you map your scores to CG requirements.

Every Coast Guard Rating and Its ASVAB Score Requirement

The Coast Guard has roughly 24 enlisted ratings, fewer than any other branch. That makes this list manageable, and it means we can show you every single one.

The “Minimum Score” column is the sum of the subtests listed in the formula column. Some ratings also require a minimum score on a specific subtest, listed under “Extra Requirements.”

Note: the Coast Guard lowered A-school score requirements by approximately 10 points across many ratings in October 2021 to expand access. These are the current thresholds, but always confirm with your recruiter since requirements can shift based on service needs.

Worked Example: Checking Your Scores Against CG Ratings

Understanding your coast guard asvab score requirements is easier with a real example. Say Jordan's ASVAB subtest standard scores look like this: AR 55, MK 48, EI 42, GS 45, VE 52, MC 47, AS 50.

IT (Information Systems Technician)

Needs AR+MK+EI+GS >= 171.

55 + 48 + 42 + 45 = 190

AR minimum of 52? Jordan has 55. Qualifies.

BM (Boatswain's Mate)

Needs VE+AR >= 101.

52 + 55 = 107

Qualifies.

AMT (Aviation Maintenance Technician)

Needs VE+AR+MK+AS >= 213 with AR >= 52.

52 + 55 + 48 + 50 = 205

Falls short by 8 points. Does not qualify.

HS (Health Services Technician)

Needs VE+MK >= 154.

52 + 48 = 100

Needs 154. Does not qualify. HS has one of the highest two-subtest thresholds in the Coast Guard.

Jordan qualifies for 15 of the 24 ratings based on these scores. The three misses above show the range: AMT is close (8 points short), while HS requires a fundamentally different score profile.

Coast Guard Officer Programs: The GT 109 Threshold

Every Coast Guard officer commissioning path runs through the same gate: a GT score of 109 or higher.

This applies to all four programs: Officer Candidate School (OCS), Selected Reserve Direct Commission (SRDC), Pre-Commissioning Program for Enlisted Personnel (PPEP), and the College Student Pre-Commissioning Initiative (CSPI).

GT = VE + AR

If your VE is 55 and your AR is 54, your GT is 109. That barely clears the bar. A GT of 109 is higher than many Army and Marines officer thresholds, reflecting the Coast Guard's selectivity even at the officer level.

Don't have your ASVAB scores handy? You can also qualify with an SAT score of 1,100 (combined verbal and math) or an ACT score of 23. These alternative paths exist because officer candidates often come from college backgrounds where a recent ASVAB may not be available.

What Happens If You Enlist Without a Rating (The Non-Rate Path)

Not everyone enters the Coast Guard with a guaranteed rating. If your ASVAB scores don't qualify you for a specific A-school, or if your preferred rating has no open slots, you'll enlist as an undesignated non-rate.

Boot Camp8 weeks at Cape May, NJ
Non-RatePosted to a unit as SN (Seaman), FN (Fireman), or AN (Airman)
StrikeAfter time in service, apply for a rating through on-the-job training or formal A-school
Rated E-4Typical timeline is 2–3 years from non-rate to Petty Officer Third Class

The three communities determine your work environment: Seaman covers deck and admin, Fireman covers engineering and hull maintenance, Airman covers aviation. Your community assignment happens during boot camp.

The non-rate path isn't a dead end. You can study for the AFCT (covered below) to improve your scores and qualify for the rating you actually want.

Already in the Coast Guard? How to Improve Your Score with the AFCT

Your initial ASVAB scores aren't permanent. Active-duty and Reserve Coast Guard members can retake the test through the AFCT (Armed Forces Classification Test). It covers the same content as the ASVAB under a different name.

Step 1Request AFCT through your Educational Services Officer (ESO)
Step 2Schedule appointment at a DLPT/AFCT testing site
Step 3Bring valid military ID and test (electronic format only)
Step 4New scores replace ALL previous ASVAB scores

Common reasons to take the AFCT: qualifying for a new rating, meeting the GT 109 threshold for officer programs, or improving your coast guard asvab score after entering as a non-rate. ASVAB scores are valid for two years from the test date, but AFCT scores follow the same validity window, so plan accordingly if you're targeting a specific rating change timeline.

Which Subtests to Study First for Coast Guard Ratings

Not every subtest carries equal weight for your coast guard asvab score. Here's the priority order based on how frequently each subtest appears across all 24 rating formulas.

Priority 1AR (Arithmetic Reasoning): Appears in 18+ rating formulas AND feeds the AFQT. Highest-leverage subtest for CG applicants.
Priority 2VE (Word Knowledge + Paragraph Comprehension): Appears in 15+ formulas plus carries 2x weight in the AFQT formula.
Priority 3MK (Mathematics Knowledge): Appears in 12+ formulas, especially technical and aviation ratings. Also feeds the AFQT.
Priority 4EI (Electronics Information): Critical for AET, ET, IT, and EM. Skip if you're targeting deck or admin ratings.
Priority 5GS (General Science): Needed for AET, ET, IT, and MST. Lower priority unless you're targeting those specific ratings.

A focused 4–6 week study period targeting your weak subtests typically yields a 5 to 15 percentile point improvement. Start with a free practice test to find your baseline, then build a plan around your weakest AFQT subtests first.

Coast Guard ASVAB Score FAQ

What is the minimum ASVAB score for the Coast Guard?

The official AFQT minimum is 32 for high school diploma holders. It was 40 until November 2023, when the Coast Guard lowered it to address recruiting challenges. GED holders need an AFQT of 50 or higher. The Reserve minimum is 40. In practice, scoring well above the minimum gives you significantly better chances since the Coast Guard is the most selective branch.

What ASVAB score do you need for Coast Guard Rescue Swimmer (AST)?

Aviation Survival Technician (AST) requires a combined VE+AR+MK+MC score of 162 or higher, plus an AFQT of at least 65. AST also has demanding physical fitness requirements beyond the ASVAB. It's one of the most competitive ratings in any branch.

Does the Coast Guard accept a GED?

Yes, but with restrictions. You need an AFQT of 50 or higher (vs. 32 for diploma holders), and fewer than 5% of accepted Coast Guard recruits lack a diploma. Completing 15 college credit hours upgrades your status to Tier 1, giving you the same scoring threshold as diploma holders.

Can you retake the ASVAB for the Coast Guard?

Yes. The standard retake schedule is 1 month after your first test, 1 month after your second, then 6 months between each attempt after that. Active-duty members retake through the AFCT rather than the standard ASVAB. Your newest score replaces all previous scores. See our ASVAB retake guide for the full rules.

What's a good ASVAB score for the Coast Guard?

An AFQT of 50+ makes you competitive for enlistment. Scoring 65+ opens specialized ratings like AST (Rescue Swimmer) and ET (Electronics Technician). For officer programs, you need a GT score of 109 or higher. Use our score calculator to see which ratings your current scores unlock.

How is the Coast Guard different from other branches for ASVAB scoring?

The Coast Guard uses sums of individual subtest standard scores instead of named composite scores like the Army's GT, CL, or ST. Each rating has its own subtest formula. The CG also has the fewest ratings (~24 vs. 150+ Army MOSs), so qualification thresholds tend to be well-documented. See our ASVAB scores explained guide for a full comparison of how each branch handles scoring.
