1.3 Military Line Scores (GT, EL, CL, ST, MM, etc.) & MOS/AFSC Reclassification
Key Takeaways
- Line scores combine AFCT subtest standard scores to qualify members for specific MOS/AFSC/rating fields—not AFQT alone.
- Army GT = VE + AR, where VE is the WK/PC verbal composite—not 2(PC) + WK; current Army composites no longer use retired Numerical Operations or Coding Speed.
- Air Force MAGE Mechanical uses AR + AS + MC + VE per airforce.com; Electronic = AR + MK + EI + GS; Administrative = VE + MK; General = VE + AR—confirm AFSC guidance.
- GT 110 is a widely published benchmark for many Army and Marine commissioning and special-duty programs—confirm current cutoffs before testing.
- AFCT overwrites prior scores; raising one composite can lower another if weak subtests slip—prep for every required line score before sitting the exam.
1.3 Military Line Scores (GT, EL, CL, ST, MM, etc.) & MOS/AFSC Reclassification
Executive Summary: Line scores (composites) combine AFCT subtest standard scores to determine which jobs you qualify for. AFQT answers a broader eligibility question; line scores answer the job-classification question. Each Service publishes its own composite formulas and cutoffs—always verify the current proponent or career-field message before you test.
1. Subtests That Feed Line Scores
CAT-AFCT reports the full technical battery. Paper forms may combine Auto & Shop and omit Assembling Objects.
| Code | Subtest | Notes |
|---|---|---|
| GS | General Science | Life, physical, earth/space science |
| AR | Arithmetic Reasoning | Word-problem math |
| WK / PC → VE | Word Knowledge / Paragraph Comprehension | Combined into Verbal Expression (VE) using standard-score procedures (not 2PC + WK) |
| MK | Mathematics Knowledge | Algebra, geometry, number properties |
| EI | Electronics Information | Circuits, components, electrical principles |
| AS | Auto & Shop Information | On CAT, AI and SI are separate but combine into an AS score |
| MC | Mechanical Comprehension | Forces, machines, fluids, mechanical advantage |
| AO | Assembling Objects | Spatial connections; CAT form; used in some Navy / technical composites |
Retired speeded subtests (Numerical Operations, Coding Speed) no longer appear on current ASVAB/AFCT forms. Do not study obsolete formulas that still list NO or CS.
Standard scores, not raw counts: Line scores sum standard scores (typically on a 20–80 scale per subtest on score reports). You cannot add raw correct-answer totals from practice tests. Your Education Center or a current score report shows the inputs; use those numbers when you model composites.
2. U.S. Army Line Scores (Common Current Formulas)
Army uses multiple composites. Widely published current formulas (post-retirement of NO/CS) include:
| Line Score | Formula | Typical use |
|---|---|---|
| GT (General Technical) | VE + AR | OCS/WOCS packets, many technical and special-duty screens |
| CL (Clerical) | VE + AR + MK | Admin / HR / finance-type MOSs |
| EL (Electronics) | GS + AR + MK + EI | Signal, radar, electronics maintenance |
| ST (Skilled Technical) | GS + VE + MK + MC | Intel, medical, technical specialties |
| MM (Mechanical Maintenance) | GS + AS + MC + EI | Mechanics / maintenance MOSs |
| GM (General Maintenance) | GS + AS + MK + EI | General maintenance fields |
| SC (Surveillance & Communications) | VE + AR + AS + MC | Comms / surveillance-related MOSs |
| CO (Combat) | AR + AS + MC | Combat arms classification (older tables that list CS are obsolete) |
| FA (Field Artillery) | AR + MK + MC | Field artillery MOSs (older CS-based tables are obsolete) |
| OF (Operators / Food) | VE + AS + MC | Operator / food-service type fields (older NO-based tables are obsolete) |
Cutoffs change with manning needs. Use the current MOS Smartbook / MILPER message, not a third-party chart alone.
Some published Army tables list MM as GS + AS + MC + EI; others omit GS in teaching summaries. Treat the Smartbook row for your target MOS as authoritative—formulas can differ slightly by publication date.
3. Worked Example: Computing GT, CL, and EL
Suppose your score report shows these standard scores (illustrative only):
| Subtest | Standard score |
|---|---|
| WK / PC → VE | 52 |
| AR | 58 |
| MK | 50 |
| GS | 48 |
| EI | 46 |
GT = VE + AR = 52 + 58 = 110 — meets the widely published GT 110 benchmark for many Army and Marine programs.
CL = VE + AR + MK = 52 + 58 + 50 = 160 — compare to your MOS Smartbook cutoff (example: if CL 155 is required, you pass).
EL = GS + AR + MK + EI = 48 + 58 + 50 + 46 = 202 — again, check the published minimum for the signal or electronics MOS you want.
Two-point GT shortfall scenario
Now change only AR from 58 to 56 (VE stays 52):
- New GT = 52 + 56 = 108 — two points below the common GT 110 screen.
- CL drops by 2 as well (now 158) because AR appears in CL.
- EL also drops by 2 (now 200) because AR appears in EL.
This illustrates why a small AR slide can block OCS packets even when other composites still look strong. Raising AR by two standard-score points—or raising VE (via WK and/or PC)—adds two points to GT. For many members, AR prep yields faster GT gains than vocabulary alone because AR is a single high-weight subtest in the sum.
4. Study Prioritization Matrix
When you are deficient in one composite, drill the subtests that appear in that formula and that you can realistically raise before test day.
| If you are short on… | Subtests in the formula | Practical study focus |
|---|---|---|
| GT | VE, AR | Vocabulary (WK), passage strategy (PC), AR word problems and pacing |
| CL | VE, AR, MK | GT prep plus algebra/geometry (MK) |
| EL | GS, AR, MK, EI | Electronics principles (EI), science review (GS), math (MK, AR) |
| ST | GS, VE, MK, MC | Broad science + verbal + math + mechanics (levers, fluids, gears) |
| MM | GS, AS, MC, EI (verify table) | Tool/shop ID (AS), mechanical reasoning (MC), basic circuits (EI) |
| Marine MM | AS, MC, EI | Shop/auto and mechanics—no GS in the common Marine MM sum |
| Marine CL | VE, MK | Verbal composite and math knowledge |
Rule of thumb: List every composite your target MOS requires. Mark which subtests feed more than one deficient line score—those are your highest-return drills (AR and VE often appear in multiple Army composites).
5. The Multi-Composite Trap and Overwrite Risk
AFCT overwrites your prior ASVAB/AFCT standard scores. There is no “keep my old GT, only update AR” option. The new battery replaces the score of record used for classification.
Trap 1 — Optimizing one line score while breaking another: You need GT 110 for a packet and ST 105 for a target MOS. You drill only AR and raise GT to 111, but fatigue or neglected science/mechanics items lower GS or MC on test day. Your new ST might fall below the MOS minimum even though GT improved.
Trap 2 — AFQT vs line scores: A strong AFQT does not automatically qualify you for a technical MOS. AFQT is a separate percentile-style eligibility metric. Recruiters and reclassification boards look at line scores for job qualification.
Planning approach:
- Write down every required composite and cutoff for the target MOS/AFSC/rating.
- Identify shared subtests across those composites (often VE, AR, MK).
- Build a prep plan that protects weak areas in all required formulas—not only the one you are closest to passing.
- Sit the AFCT only when practice standard-score estimates show margin above each cutoff, not bare minimums on a single composite.
6. Air Force & Space Force MAGE
Air Force qualification areas (commonly called MAGE):
| Area | Composite inputs (standard scores) |
|---|---|
| M Mechanical | AR + AS + MC + VE (per current airforce.com recruiting guidance; PC and WK first form VE) |
| A Administrative | VE + MK (airforce.com lists MK with PC/WK → VE) |
| G General | VE + AR |
| E Electronic | AR + MK + EI + GS |
AFSC retraining requires meeting the published MAGE minimums for the target career field. Older research bulletins and third-party charts sometimes still show Mechanical as GS + MC + 2(AS)—that is a legacy formula; prefer current Service recruiting/AFSC guidance over decade-old PDFs.
7. Marine Corps and Navy Composites
Marine Corps primary composites commonly include:
- GT = VE + AR
- MM = AS + MC + EI
- EL = GS + AR + MK + EI
- CL = VE + MK
Navy rating formulas are job-specific sums (examples historically include nuclear-field style sums such as AR + MK + EI + GS meeting a published minimum). Some Navy formulas incorporate AO. Always check the current rating card / Career Waypoints guidance.
8. The GT 110 Benchmark
Across Army and Marine career programs, GT 110 is a widely published floor for:
- Many OCS / warrant packets
- Numerous special-duty and technical selections
A Soldier with GT 108 is typically blocked from those packets until a successful AFCT raises GT. Confirm the current published minimum—some programs require higher.
9. Third-Party Chart Traps (What to Reject)
Outdated or incorrect study charts circulate online. Reject any resource that:
| Red flag | Why it fails |
|---|---|
| Lists NO or CS in composite formulas | Those subtests are retired; CS-based CO/FA tables and NO-based OF tables are obsolete |
| Defines VE as 2(PC) + WK or raw-sum shortcuts | VE is a standard-score composite from WK and PC—not a simple doubled PC plus WK |
| Treats AFQT as a job qualifier | AFQT measures broad eligibility; MOS/AFSC/rating qualification uses line scores |
| Shows GT = GS + MK or similar | Army/Marine GT is VE + AR |
| Uses legacy Air Force Mechanical GS + MC + 2(AS) without citing current AFSC/recruiting guidance | Current airforce.com Mechanical inputs are AR + AS + MC + VE |
| Copies decade-old Army tables without a Smartbook/MILPER cite | Cutoffs and occasionally formula labels change with policy |
When a chart conflicts with your official score report or Education Center briefing, trust the current Service publication.
10. Reclassification Workflow Using AFCT
- Identify the target MOS/AFSC/rating and its current line-score formula and cutoff.
- Compare your score of record to each required composite—not only GT or AFQT.
- Prioritize subtests that appear in the deficient composites (for GT shortfalls, that is VE and AR—i.e., WK, PC, and AR).
- Complete required academic prep (BSEP/OASC/FAST or Service equivalent) and obtain command authorization.
- Sit the AFCT only when ready—the new score overwrites the old one. Plan for all required composites before you test.
