What this means
Official Army Chapter 10c PDF lists GT 110 and CO 100; 18X is the separate enlistment option and remains a pending record. OPAT, SERE-C, clearance and the qualification course remain separate.
The score listed above is the minimum line score threshold from the official Army MOS specification. Meeting this threshold does not guarantee enlistment — additional requirements such as OPAT physical testing, security clearance, medical screening, and training availability are evaluated separately by your recruiter. To see how GT 110 compares with the rest of the Army, read what counts as a good ASVAB score. Enlistment itself needs the Army's AFQT minimum, which most recent recruits clear by a wide margin (see the average ASVAB score).
Which ASVAB subtests count toward 18E
18E is judged on 2 line scores. The subtests listed below are the Army's nominal definition of each aptitude area from DA PAM 611-21, Military Occupational Classification and Structure, Table 10-1 (ASVAB aptitude area composites). The score actually printed on your report is computed on the 1997 scale as a weighted sum of seven standard scores (DMDC 2004, Table 2.7) and may give weight to subtests outside the nominal list; GT is the exception and equals AR + VE exactly. Use the line score on your report, or compute it from your standard scores; the score chart shows where GT ≥ 110 and CO ≥ 100 sits among every Army line score range.
VE (verbal: WK and PC) + AR
WK (Word Knowledge), PC (Paragraph Comprehension), AR (Arithmetic Reasoning).
AR + CS + AS + MC
AR (Arithmetic Reasoning), CS (Coding Speed), AS (Auto and Shop Information), MC (Mechanical Comprehension).
CS is a legacy subtest no longer administered; the Army scores CO from the remaining subtests.
If your score is below GT ≥ 110 and CO ≥ 100
Your ASVAB report lists every line score, so start by finding GT and CO and noting the exact gap. A small gap in one composite is usually closed by improving the subtests that feed it, and each subtest counts toward several line scores at once.
GT is the one line score you can compute from just two numbers: enter AR and VE on the GT score calculator to see exactly where you stand against every job that names GT.

Not testable: CS no longer appear on the ASVAB, so there is nothing to practice for them.
A retest is subject to the official retest waiting periods; ask your recruiter before planning around one. Practice results here are raw scores and never convert into an official line score.
Special Forces jobs ranked by ASVAB threshold
All 4 currently verified CMF 18 entries on this site, ordered by the lowest score that satisfies each rule. 18E sits at position 4: 0 jobs list a lower threshold and 0 list a higher one. Thresholds in different line scores are not directly comparable.

Other Army jobs judged on GT (General Technical)
Because these MOS share the GT line score with 18E, the same subtests decide your standing for all of them. Jobs at or below 18E's threshold are fallback options; jobs above it are what a higher GT unlocks.
- 31D Criminal Investigation Special Agent — GT ≥ 110
- 38W Civil Affairs Medical Sergeant — GT ≥ 110 and ST ≥ 101
- 42T Talent Acquisition Specialist — GT ≥ 110
- 51C Contracting Noncommissioned Officer — GT ≥ 110
- 79R Recruiter — GT ≥ 110
- 79T Recruiting and Retention NCO — GT ≥ 110

Frequently asked questions
What ASVAB score do I need for 18E Special Forces Communications Sergeant?
The verified score threshold recorded for this MOS is GT ≥ 110 and CO ≥ 100. Other requirements such as OPAT, clearance, and training are separate.
Which ASVAB subtests count toward the GT and CO score for 18E?
GT (General Technical) is nominally VE (verbal: WK and PC) + AR. CO (Combat) is nominally AR + CS + AS + MC. The reported score is a weighted sum of seven standard scores on the 1997 scale, so subtests outside that list can also count. Compare the line score printed on your ASVAB report against GT ≥ 110 and CO ≥ 100, or compute it from your standard scores with the calculator.
Is AFQT enough to qualify for 18E?
No. AFQT is used for general enlistment qualification. 18E uses specific Army line scores (GT ≥ 110 and CO ≥ 100), and the line-score rule shown here is the verified threshold. These are composite scores calculated from ASVAB subtests and are different from your AFQT percentile.
Are there Special Forces jobs with a lower ASVAB threshold than 18E?
No. 18E has the lowest entry threshold among the 4 currently verified CMF 18 entries on this site; 0 list a higher one.
Where does this 18E score requirement come from?
The verified threshold is recorded from the official Army MOS specification document. Initial award, Chapter 10c; awarded after selection and the Special Forces Qualification Course. Source checked on 2026-11-12.
