Understanding ASVAB Scoring
ASVAB scoring involves multiple score types that serve different purposes in military qualification and job placement.
AFQT Scores Explained
Your AFQT score represents how you performed compared to other test-takers aged 18-23. A score of 70 means you performed better than 70% of the reference group. According to Department of Defense data, approximately 23% of test-takers score between 50-64, making this the most common score range.
The AFQT score does not indicate the percentage of questions answered correctly. Instead, it’s a percentile ranking showing your performance relative to the national sample group.
Standard Scores
Each ASVAB subtest provides a standard score calculated using raw scores converted through a standard distribution with a mean of 50 and standard deviation of 10. Most recruits score between 30-70 on individual subtests.
Composite (Line Scores)
Each military branch uses different score combinations to determine candidate aptitude for specific job categories. For example:
- Army Clerical: Word Knowledge + Paragraph Comprehension + Mathematics Knowledge + Arithmetic Reasoning
- Marine Electronics Repair: General Science + Arithmetic Reasoning + Mathematics Knowledge + Electronics Information
Minimum ASVAB Scores by Military Branch
| Military Branch | High School Diploma | GED/Equivalent | Special Notes |
|---|---|---|---|
| Army | 31 | 50 | Score of 50 required for enlistment bonuses |
| Navy | 31 | 50 | Pilot program allows 10-30 percentile with line score minimums |
| Air Force | 31 | 50 + 15 college credits | Officers take AFOQT instead |
| Marines | 31 | 50 | Waivers available for special skills |
| Coast Guard | 40 | 47 | Average accepted recruit scores 70.4 |
