Enlisting With a GED: Education Tiers and AFQT Minimums

How the education tiers work

The Defense Department sorts every enlistment applicant into one of three education tiers, a system it put in place in 1987. Each Service writes the definitions into its own regulations. The Coast Guard says outright that it uses the Defense Department criteria, and DAFMAN 36-2032 says the Air Force and Space Force tiers align with DoD Instruction 1145.01.

The Services do not file every credential the same way. DAFMAN 36-2032 puts a virtual or distance school diploma in Tier One, while the Coast Guard table puts an online distance learning diploma in Tier II. If your credential is anything other than a standard diploma or a GED, ask the recruiter how that specific Service codes it before you test.

Why Tier 2 carries a higher floor

The reason is attrition. The Defense Department's FY 2002 population report put first-term completion at 80 percent for high school graduates against 50 percent for non-graduates, and it notes that GED holders have shown higher first-term attrition since the 1970s. DoD Instruction 1304.26 lets the Services give GED holders lower enlistment priority on the strength of those attrition rates.

Tier 2 slots are rationed. DAFMAN 36-2032, paragraph 3.6.8.1, requires each component to make at least 90 percent of a fiscal year's accessions Tier One and at least 60 percent AFQT Category IIIA or higher, a score of 50 or above. Both figures come from DoD Instruction 1145.01, which says the remaining 10 percent will be mostly Tier 2. You can see the effect on the Air Force Reserve and Air National Guard pages: GED holders wait for a GED slot to open, and the wait can reach a year.

What each Service publishes for GED holders

The table shows only numbers stated in a current Service source, and those numbers move with recruiting conditions. "Not published" means the Service prints no number, not that it has no standard. Diploma-holder minimums in full are on the minimum ASVAB scores by branch page.

The Army's ASVAB page says you need at least a 31 to enlist and gives no separate GED figure. Its Future Soldier Preparatory Course runs a 90-day academic track for applicants who score at least 21, and a 30-day option with one retest for scores of 31 to 49.

The Navy requires a diploma or GED and a qualifying score but prints no number. Any Navy GED minimum you find on a third-party site did not come from the Navy.

For the Air Force and Space Force, DAFMAN 36-2032 paragraph 3.6.8.2.2.2 sets 50 for Tier Two and requires an approved Service Eligibility Determination for anyone below 50. The Reserve and Air National Guard pages ask GED holders for 65, above the manual's 50, so confirm the current figure with a recruiter if you are joining either one.

Two Services attach conditions to the GED number. The Marine Corps page asks for a minimum of 31, or 50 and above with a GED or nontraditional diploma, so the 50 covers more than GED holders. Each Marine job field then checks its own line scores, listed in Marine Corps jobs by ASVAB score. The Coast Guard lists 47 for Tier II, but its instruction also requires the Accessions Division to approve every Tier II enlistment.

Under all of this sits federal law. Title 10, section 520(b) bars a non-graduate from enlisting below the 31st percentile, and section 520(a) caps recruits scoring 10 to 30 at 4 percent of a Service's active duty enlistments in a fiscal year unless the Secretary of Defense raises the cap, to no more than 20 percent.

Routes from Tier 2 to Tier 1

Fifteen semester hours of college

Fifteen semester hours is five 3-credit courses at an accredited college. The sources do not agree on how they count it, or on how quarter hours convert.

Ask the recruiter which credits count, and bring an official transcript. The GED Testing Service says a score of 175 or higher on a subject may qualify you for up to 10 college credit hours. No Service source reviewed here says whether that credit counts toward the 15, so treat it as unconfirmed.

If you are still enrolled in school, the diploma is the shorter path. DAFMAN 36-2032 lets a high school senior start processing with a statement from school officials, and the ASVAB in high school page covers testing while you finish.

The National Guard's GED Plus program

The Army National Guard started GED Plus in 2006 at Camp Robinson in North Little Rock, Arkansas. Recruits who had left high school without a diploma enlisted in the Guard, attended a course at Camp Robinson that mixed academics with military basic training, and shipped to Basic Combat Training after earning a GED. A Guard report from February 2011 counted its 10,000th graduate, up from 493 in the first year.

The name is older than the Guard program. The Defense Department's FY 2002 population report describes an experimental Army GED+ program from FY 2000 that let up to 4,000 active and 2,000 reserve applicants with a GED or no credential enlist without counting against the 90 percent Tier 1 benchmark.

Two cautions. GED Plus moved Tier 3 applicants into Tier 2, not into Tier 1, because its graduates left with a GED. And no current Guard source confirmed that the program still runs in this form, so ask a National Guard recruiter what replaced it in your state.

The GED is not the ASVAB

The GED has four subject tests: Mathematical Reasoning in 115 minutes, Reasoning Through Language Arts in 150, Social Studies in 70 and Science in 90. You pass with a 145 on each subject. The result is a credential, and none of its scores count toward enlistment.

The ASVAB's AFQT uses four subtests: Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning and Mathematics Knowledge. Your result is a percentile against a national sample of young adults, explained in how the AFQT is calculated. The content does overlap: GED math and reading practice carries straight into AR, MK and PC.

A study plan aimed at 50

The AFQT composite is AR plus MK plus two times Verbal Expression, the score built from WK and PC. On the 1997 score scale a 31 needs a composite of 183, a 47 needs 199 and a 50 needs 202. The step from the general floor to the GED floor is 19 composite points.

A worked example: standard scores of 48 in WK and PC and 45 in AR and MK give a Verbal Expression of 48, a composite of 186 and an AFQT of 34. Raise WK and PC by 4 points each and VE rises to 52, adding 8 to the composite. Add 4 points each in AR and MK and the composite reaches 202, an AFQT of 50. The same 50 also comes from 8 points each in AR and MK with no verbal gain at all.

Start with a timed practice AFQT to find your weakest standard score, then put most of your study time there, using the subject drills in how to improve your AFQT score. Aim to score clear of 50 in practice, not at it. One bad subtest on test day can cost the 3 composite points that separate 47 from 50. The good ASVAB score page shows what a margin above 50 adds for job choice.

Plan your attempts around the retest rules. After your first ASVAB you wait 1 calendar month, after the first retest another month, and after any later retest 6 months. Scores stay valid for 2 years, so a strong result now still counts if your college credits or GED slot take a year to arrive.
