How ASVAB line scores work
The Armed Services Vocational Aptitude Battery (ASVAB) consists of 10 subtests. Your raw scores on these subtests are combined into 10 Army-specific line scores, each used by USAREC to determine MOS eligibility:
- GT — General Technical: Word Knowledge + Paragraph Comprehension + Arithmetic Reasoning
- CL — Clerical: Word Knowledge + Paragraph Comprehension + Arithmetic Reasoning + Mathematics Knowledge
- CO — Combat: Auto and Shop Information + Mechanical Comprehension + Word Knowledge + Paragraph Comprehension
- EL — Electronics: General Science + Arithmetic Reasoning + Mathematics Knowledge + Electronics Information
- FA — Field Artillery: Arithmetic Reasoning + Mathematics Knowledge + Mechanical Comprehension
- GM — General Maintenance: General Science + Auto and Shop + Mathematics Knowledge + Electronics Information
- MM — Mechanical Maintenance: Auto and Shop + Mechanical Comprehension + Electronics Information
- OF — Operators and Food: Word Knowledge + Paragraph Comprehension + Auto and Shop + Mechanical Comprehension
- SC — Surveillance and Communications: Word Knowledge + Paragraph Comprehension + Auto and Shop + Mechanical Comprehension
- ST — Skilled Technical: Word Knowledge + Paragraph Comprehension + General Science + Mechanical Comprehension + Mathematics Knowledge
Line scores typically range from 40 to 160. The mean is 100, with a standard deviation of about 20. A score of 120+ in any line is considered competitive for technical MOS.
AFQT vs Line Scores
You'll see both AFQT and line scores from ASVAB:
- AFQT (Armed Forces Qualification Test): A single 1-99 percentile based on Arithmetic Reasoning + Word Knowledge + Paragraph Comprehension + Mathematics Knowledge. This is what determines whether you can ENLIST in the Army at all. Minimum AFQT for Army enlistment is 31 (recruits with HS diploma) or 50(GED recruits).
- Line Scores: Specific to MOS qualification. Even with an AFQT of 80, you might not qualify for a specific MOS if your relevant line score is too low. For example, 92A (Automated Logistical Specialist) needs CL≥90; if you have AFQT 80 but CL 85, you don't qualify until CL improves.
Strategies to maximize your options
- Study before your first ASVAB. Free prep includes Khan Academy (math + reading sections), the official practice questions at officialasvab.com, and the Department of Defense ASVAB Career Exploration Program (asvabprogram.com). Quality prep can lift line scores by 15-30 points, which is often the difference between qualifying for combat-arms MOS and qualifying for high-paying technical fields.
- Identify your target MOS BEFORE testing. Some MOS need GT scores (administrative, intelligence, cyber); others need MM (mechanic, aviation); others need EL (electronics, signal). Focus prep on the subtests that build YOUR target line score.
- Don't accept a low first score. If you score below your target, you can retake ASVAB after a 1-month waiting period (and again after 1 more month). Three attempts in a row are allowed; beyond that, requires 6-month wait.
- Verify with a recruiter BEFORE signing. Line scores in any third-party compilation should be cross-checked with your USAREC recruiter, who has authoritative access to current DA Pam 611-21 prerequisites, monthly slot availability, and any waivers your specific situation may unlock.
- Consider DLAB if interested in language. Several intelligence MOS (35M, 35P) require DLAB (Defense Language Aptitude Battery) score, which is a separate test from ASVAB. Score ≥107 opens up linguist careers.
High-impact MOS to consider
Based on civilian career portability after service:
- Cyber (17C, 25D, 35Q): ST≥112 and GT≥110 required. Translates to $80k-$150k civilian cybersecurity jobs.
- Aviation Repair (15B-Y): MM≥99-105. Strong civilian aviation maintenance / FAA A&P licensing pathway.
- Medical (68W, 68C, 68F): ST≥101, GT≥107. Combat medic / nursing translates well to civilian healthcare.
- Intelligence Analyst (35F, 35G): ST≥101. Government and contractor analyst roles post-service.
- EOD (89D): GM≥105. Highest-paying civilian explosives careers; high deployment bonus history.
- Linguist (35P, 35M): DLAB≥107. Defense contractor roles; CIA/FBI/DEA opportunities.
- Information Technology (25B, 25N): ST≥95-102, EL≥102+. Strong civilian IT crossover with TS clearance bonus.
MOS with strong civilian-portability tend to require higher ST or EL scores. Investing in math + electronics study before ASVAB pays dividends across the rest of your career.
Important caveats
- Quotas vary by month. Even if you qualify line-score-wise, your USAREC office must have a slot available in that MOS in that month. Some MOS are perpetually full; others rotate through periods of need.
- Special programs add requirements. Airborne, Ranger, Special Forces, EOD, etc. have physical and medical requirements beyond ASVAB. Eligibility flowchart varies.
- Security clearance. Intelligence, cyber, and certain technical MOS require Secret or Top Secret clearance — your background investigation determines if you can fill the slot, separate from ASVAB.
- Medical disqualifications. Color vision (electronics MOS), height/weight, certain medical history can disqualify even high-scorers from specific MOS.
- Treat the line scores here as a planning tool, not a contract. The authoritative sources are DA Pam 611-21 and your USAREC enlistment paperwork. Final eligibility lives in the contract you sign.
Active Army vs Army Reserve vs Army National Guard — the line-score nuance
The Active Component (regular Army), the U.S. Army Reserve (USAR), and the Army National Guard (ARNG) all enlist under DA Pam 611-21 line-score minimums, but they recruit under separate commands and the slot availability is rarely the same in a given month. The Active Component is recruited by USAREC. The Army Reserve is recruited by USAREC's Army Reserve Recruiting Battalions (USAREC-AR). The National Guard is recruited at the state level by each state's Adjutant General — Guard recruiters answer to the Governor of their state until federalized under 10 USC.
In practical terms this means three things for someone studying these line scores. First, an MOS that is closed in the Active Component for the month may still be open in Reserve or Guard, and the same line score qualifies the candidate. Second, certain MOS exist only in one component — for example, many civil-affairs and PSYOP roles sit primarily in USAR, and Guard-heavy MOS like 91D (Power-Generation Equipment Repairer) reflect the Guard's emergency response mission. Third, the bonus and incentive structure differs: Reserve and Guard enlistment bonuses are authorized under different DoD instructions than Active bonuses and rotate on a different schedule.
The line scores in the matcher above are the Active Component DA Pam 611-21 minimums. Reserve and Guard minimums for the same MOS are generally the same, but waivers, hometown-recruiter discretion, and state-level Guard exceptions can shift the picture. If the goal is a specific MOS, ask all three recruiters — Active, Reserve, and Guard — before deciding which component to enlist into.
