Most people who plan to enlist in the Navy fixate on the AFQT. That number gets you in the door, but it does not pick your rating. Your line scores do. The Navy uses eight composite scores, drawn from the same nine ASVAB subtests, to decide which jobs you actually qualify for.
This guide explains each of the eight Navy line scores, which subtests feed them, and why two applicants with the same AFQT can end up with very different rating options.
What a Navy Line Score Is
A Navy line score is a composite. It adds your scores from two or more ASVAB subtests to produce a number that the Navy compares against a rating-specific minimum. The Navy publishes these formulas in the rating qualifications. Each rating uses a different combination.
The eight line scores the Navy uses are VE, AR, MK, MC, AS, AO, EI, and GS. Some Cryptologic and Cyber ratings also use a Cyber Test (CT) score, but CT is a separate aptitude test layered on top of the standard ASVAB.
There is no single “Navy line score.” A rating tells you which composite formula it uses, and you need to clear that specific number. The full rating-by-rating table lists each formula.
The Eight Navy Line Scores and What They Test
Below is a quick reference for each line score and the underlying ASVAB subtest or subtests that produce it.
| Line score | Stands for | Source subtest(s) | What it measures |
|---|---|---|---|
| VE | Verbal Expression | Word Knowledge (WK) + Paragraph Comprehension (PC) | Vocabulary and reading comprehension, combined |
| AR | Arithmetic Reasoning | Arithmetic Reasoning (AR) | Math word problems and basic algebra |
| MK | Mathematics Knowledge | Mathematics Knowledge (MK) | Math concepts including geometry and algebra |
| MC | Mechanical Comprehension | Mechanical Comprehension (MC) | Mechanical systems and physical principles |
| AS | Auto and Shop Information | Auto and Shop Information (AS) | Auto maintenance and shop tools |
| AO | Assembling Objects | Assembling Objects (AO) | Spatial reasoning and visual assembly |
| EI | Electronics Information | Electronics Information (EI) | Basic electronics and electrical concepts |
| GS | General Science | General Science (GS) | Basic science, including life and earth science |
VE is the odd one out. It is not a separate subtest. The Navy calculates it by combining your raw scores from Word Knowledge and Paragraph Comprehension and converting that to the VE composite. Because VE shows up in so many rating formulas, your performance on WK and PC has cascading effects.

Why Line Scores Matter More Than AFQT for Rating Selection
The AFQT decides eligibility. The Navy minimum for a high school diploma holder is 31. With a GED, it is 50. Hit that, and you can enlist. But hitting the AFQT minimum does not give you any rating choice. It gives you whatever rating is left.
Rating selection happens through line scores. Each rating has its own composite formula and threshold. Two applicants can both have an AFQT of 65, but if one has stronger Mechanical Comprehension and General Science scores, that applicant qualifies for more technical ratings. The other might only qualify for support ratings with lower composite cutoffs.
A few examples from the Navy ASVAB requirements table:
- Hospital Corpsman (HM) needs AR + MK + GS + VE = 208 (or alternates).
- Electronics Technician (ET) needs AR + MK + EI + GS = 222 (or AR + 2MK + GS = 222).
- Cyber Warfare Technician (CWT) needs AR + 2MK + GS = 255 (or alternates).
- Culinary Specialist (CS) needs VE + AR = 76.
- Logistics Specialist (LS) needs VE + AR = 92.
You can pass the AFQT and not qualify for any rating you actually want. That is the most common reason new enlistees end up frustrated with the job their detailer offered them.
How the Eight Line Scores Group Into Rating Families
Some patterns help you read the table faster.
Engineering and electronics ratings
These lean on AR, MK, EI, and GS. Ratings like ET, FC, STG, and the submarine-track SECF use AR + MK + EI + GS = 218 to 222. If you want a technical engineering rating, those four subtests are where your prep should land.
Mechanical and aviation maintenance ratings
These lean on VE, AR, MK, AS, MC, and AO. Aviation ratings like AT, AE, AM, and AME mostly use VE + AR + MK + (AS, MC, or AO) = 200 to 210. Engineman (EN) and Machinist’s Mate (MM) sit in similar territory.
Verbal and administrative ratings
These lean on VE, AR, and MK. Yeoman (YN), Personnel Specialist (PS), and Religious Program Specialist (RP) cluster around VE + MK = 99 to 105. These have the lowest composite thresholds in the rating list.
Information warfare and cyber ratings
These layer the Cyber Test (CT) on top of AR, MK, and VE. The Cryptologic Technician ratings and CWT use CT thresholds of 55 to 60 alongside high composite minimums. Cryptologic Technician Interpretive (CTI) also requires a DLAB score of 100 for language tracks.
Nuclear ratings
The nuclear-track ratings (MMN, EMN, ETN) use a different system entirely. The Navy looks at VE + AR + MK + MC = 235 and AR + MK + EI + GS = 235, both required. Applicants who fall short take the Navy Advanced Programs Test (NAPT), which can be added to either composite. The NAPT target score is 55.
What This Means for Your Prep
Your study time is finite. The smart move is to figure out which line scores feed the ratings you want, then concentrate prep on the subtests inside those composites.
Verbal Expression (VE) shows up in dozens of rating formulas. Word Knowledge and Paragraph Comprehension prep moves many composites at once. Arithmetic Reasoning (AR) and Mathematics Knowledge (MK) appear in almost every composite formula. Strong math is the single biggest force multiplier on the Navy line score table.
After that, the technical subtests (MC, EI, GS, AS) split by rating family. If you want aviation maintenance, push MC and AS. If you want engineering or electronics, push EI and GS. If you want nuclear, you need all four math and science subtests at high marks.
A structured ASVAB study guide walks through this targeting in more detail.
What Counts as a “Good” Line Score
There is no single passing score for a line score, because the rating formula tells you the threshold. A VE of 50 is fine for Logistics Specialist (VE + AR = 92). It is not enough for Intelligence Specialist (VE + AR + MK + GS = 215) unless the other three are strong.
Use this as a working framework:
- 50s on every subtest gets you AFQT eligibility and a few support ratings.
- 60s opens up most aviation maintenance and engineering ratings.
- 70s opens up Hospital Corpsman, Cryptologic Technician Maintenance (CTM), and most technical pipelines.
- 80s plus a strong Cyber Test puts you in cyber, intelligence, and nuclear range.
These ranges are rough. Always check the exact composite formula for the rating you want against the Navy ASVAB requirements table.
Retesting If Your Line Scores Fall Short
If you take the ASVAB and the line scores for your target rating do not add up, you can retake the test. The waiting periods are:
- First retest: After 30 days
- Second retest: After another 30 days
- Additional retests: After 6 months
A retake replaces your full set of scores. You cannot pick and choose. If you go in for a retest, prepare for every subtest that affects your target composite. Walking in cold can lower scores that were already strong enough.
Bottom Line
Your AFQT gets you in. Your line scores decide what you do. The eight Navy line scores (VE, AR, MK, MC, AS, AO, EI, GS) combine into rating-specific composites that vary by hundreds of points across the rating list. Map the composites for the ratings you want before you study. Then put your prep time on the subtests that feed those composites.
