How ASVAB Line Scores Work (and Which Jobs Each One Unlocks)

Last updated June 10, 2026

An ASVAB line score — also called a composite — is the sum of two to four of your ASVAB subtest scores. The military uses these composites, not your overall AFQT percentile, to decide which specific jobs you can be offered. Your AFQT decides whether you can enlist at all; your line scores decide what you can do once you are in.

The single most useful thing to memorize up front is the Verbal Expression score: VE = WK + PC. Verbal Expression bundles your Word Knowledge and Paragraph Comprehension subtests into one number, and that number feeds into most of the Army line scores. Once you know your VE, the rest of the composites are just simple addition.

For example, the General Technical composite is GT = VE + AR. The Skilled Technical composite is ST = GS + VE + MK + MC. Each job in the Army catalog lists the composites it requires and the minimum score you need in each — so two applicants with the same AFQT can qualify for completely different jobs depending on how their subtest scores are distributed.

Subtests vs. line scores vs. AFQT

There are three layers to ASVAB scoring, and confusing them is the most common mistake applicants make. The first layer is the subtests: nine standardized sections such as Arithmetic Reasoning (AR), Word Knowledge (WK), Mathematics Knowledge (MK), and Mechanical Comprehension (MC). Each subtest produces a standard score.

The second layer is the AFQT — the Armed Forces Qualification Test. It is built from only four subtests using the formula 2 × VE + AR + MK, then converted to a percentile from 1 to 99. The AFQT is the enlistment gate: it determines whether the military will take you at all.

The third layer is the line scores. These are job gates. A high AFQT opens the door, but each individual job still requires specific composites at specific minimums. You can have an excellent AFQT and still be blocked from a particular job because one composite it needs falls short.

The 10 Army composites and their formulas

The Army builds ten line scores from your subtests. Remember that VE = WK + PC throughout. Each composite tends to map onto a family of jobs, which is why targeting the right composite matters more than chasing a single big number.

  • GT — General Technical = VE + AR. The all-purpose composite; gates general, administrative, and leadership-track jobs.
  • CL — Clerical = VE + AR + MK. Administrative and records roles.
  • CO — Combat = VE + AS + MC. Infantry and direct-combat roles.
  • EL — Electronics = GS + AR + MK + EI. Electronics repair and technical signal jobs.
  • FA — Field Artillery = AR + MK + MC. Artillery and fire-support roles.
  • GM — General Maintenance = GS + AS + MK + EI. Mechanical and maintenance trades.
  • MM — Mechanical Maintenance = AS + MC + EI. Vehicle and equipment mechanics.
  • OF — Operators and Food = VE + AS + MC. Equipment operators and food service.
  • SC — Surveillance and Communications = VE + AR + AS + MC. Intelligence-adjacent and comms roles.
  • ST — Skilled Technical = GS + VE + MK + MC. Skilled technical jobs such as medical, intelligence analysis, and engineering support.

A worked example

Suppose your subtest standard scores come back as WK 55, PC 50, AR 60, MK 58, GS 52, AS 48, MC 50, and EI 45. First compute Verbal Expression: VE = WK + PC = 55 + 50 = 105.

Now the composites fall out by addition. GT = VE + AR = 105 + 60 = 165. That is a strong General Technical score. CO (Combat) = VE + AS + MC = 105 + 48 + 50 = 203. ST (Skilled Technical) = GS + VE + MK + MC = 52 + 105 + 58 + 50 = 265.

Notice that the same subtests produce very different composite totals because each formula adds a different combination. If a job you want needs a high ST but you scored low on General Science (GS) or Mechanical Comprehension (MC), those two subtests are exactly where extra study would move your number.

How line scores gate specific MOS

Every Army MOS (Military Occupational Specialty) publishes minimum composite requirements. For instance, an infantry job may require a Combat (CO) score at or above a set threshold. When premil checks your eligibility, it compares each required composite against your actual score and reports any shortfall — including exactly how many points you are missing on each composite.

This is why falling short on one composite can block a job even when your AFQT is excellent: the job cares about that one number. As a quick reading guide, premil interprets a single composite using these bands — 140 and above is Excellent, 120–139 is Above Average, 100–119 is Average, 80–99 is Below Average, and below 80 is Low. The bands are a feel for strength, not a guarantee of qualification, which always depends on the specific job minimums.

How to raise the line score for the job you want

Because each composite is just a sum of specific subtests, you can raise a target line score by drilling only the subtests that feed it. Want a higher Skilled Technical (ST = GS + VE + MK + MC)? Focus on General Science, the verbal subtests, Mathematics Knowledge, and Mechanical Comprehension — not Auto and Shop, which does not contribute to ST at all.

This targeted approach is far more efficient than studying everything equally. Decide which job you want, look up the composites it requires, map those composites back to their subtests using the formulas above, and spend your study time where it actually moves the number that gates your job.
