How ASVAB Scores Work
The ASVAB produces several types of scores. Understanding each type is essential for planning your military career. The three main score types are: Standard Scores (individual subtest scores), the AFQT Score (determines enlistment eligibility), and Composite Scores (determine job qualification).
AFQT Score Formula
The AFQT (Armed Forces Qualification Test) score is the single most important number from your ASVAB. It determines whether you can enlist in any branch of the military. The formula combines four subtests:
Where AR = Arithmetic Reasoning and MK = Mathematics Knowledge. Official ASVAB scoring derives Verbal Expression (VE) from Word Knowledge and Paragraph Comprehension using an official conversion table; VE is not simply WK + PC. The resulting composite is then converted to an AFQT percentile using official scoring tables. Those tables are not reproduced here.
AFQT Score Categories
| Category | Percentile Range | Description | % of Test Takers |
|---|---|---|---|
| Category I | 93-99 | Outstanding | ~4% |
| Category II | 65-92 | Above Average | ~28% |
| Category IIIA | 50-64 | Average | ~16% |
| Category IIIB | 31-49 | Below Average | ~21% |
| Category IV | 10-30 | Well Below Average | ~21% |
| Category V | 1-9 | Not Eligible | ~10% |
Composite Scores (Line Scores)
Beyond the AFQT, the ASVAB generates composite scores that determine which Military Occupational Specialties (MOS) you qualify for. Each branch uses different composite score formulas. Here are the most common Army composite scores:
| Composite | Name | Formula | Example MOS |
|---|---|---|---|
| GT | General Technical | VE + AR | Intelligence, Special Forces |
| CL | Clerical | VE + AR + MK | Human Resources, Finance |
| CO | Combat | AR + CS + AS + MC | Infantry, Armor |
| EL | Electronics | GS + AR + MK + EI | Signal, Cyber |
| MM | Mechanical Maintenance | NO + AS + MC + EI | Vehicle Mechanic |
| ST | Skilled Technical | GS + VE + MK + MC | Medical, Engineering |
What Score Do You Need?
The answer depends on your goals. For basic enlistment, you need to meet the AFQT minimum for your desired branch. However, for competitive MOS selections (like Special Forces, Cyber, or Intelligence), you will need much higher scores. Many desirable Army MOS require a GT score of 110+, and Air Force tech jobs often require specific MAGE (Mechanical, Administrative, General, Electronics) composite scores of 60+.

How is the AFQT score calculated?
The AFQT uses four subtests: AFQT raw composite = 2 × VE + AR + MK. The raw score is converted to a percentile (1-99) based on a nationally representative sample of 18-23 year olds.
What is a good ASVAB score?
An AFQT score of 50 is average. Scores of 60+ are considered good, 70+ very good, and 80+ excellent. Higher scores qualify you for more MOS options and may earn enlistment bonuses.
How long are ASVAB scores valid?
ASVAB scores are valid for 2 years from the test date. After 2 years, you must retake the ASVAB to enlist. If you are already in DEP (Delayed Entry Program), your scores remain valid for the duration of your DEP contract.
Can I improve my ASVAB score?
Yes. Most people improve significantly with targeted study. Use our study guide and diagnostic test to identify weak areas, then practice those sections. Average improvement with 4-6 weeks of study is 10-15 AFQT percentile points.
