The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple-aptitude test used by the U.S. military to help determine enlistment eligibility and qualifications for military occupations.
Your ASVAB results can influence which military jobs you qualify for, so preparation is important. Understanding the test and studying the subjects you find difficult can help you make the most of your opportunities.
What Is on the ASVAB?
The ASVAB measures knowledge and abilities across several subjects, including:
- Arithmetic Reasoning: Solving mathematics word problems.
- Mathematics Knowledge: High-school mathematics concepts, including algebra and geometry.
- Word Knowledge: Understanding vocabulary and word meanings.
- Paragraph Comprehension: Understanding written passages.
- General Science: Basic physical and biological science.
- Electronics Information: Electrical and electronic principles.
- Auto and Shop Information: Automotive and workshop knowledge.
- Mechanical Comprehension: Mechanical and physical principles.
- Assembling Objects: Understanding how objects fit together.
The exact subtest structure depends on the testing format. Review the official ASVAB information for the version you will take.
Understanding Your AFQT Score
The Armed Forces Qualification Test (AFQT) score is calculated using four ASVAB subtests:
- Arithmetic Reasoning (AR)
- Mathematics Knowledge (MK)
- Word Knowledge (WK)
- Paragraph Comprehension (PC)
Your AFQT score is reported as a percentile from 1 to 99. For example, a score of 70 means you performed as well as or better than approximately 70 percent of the reference population.
The AFQT primarily determines eligibility for enlistment. The military also uses combinations of ASVAB subtest scores, often called line scores or composite scores, to determine qualifications for particular occupations.
Minimum qualifying scores and occupational requirements vary by service branch and can change. Ask a recruiter about the current requirements for the jobs you are considering.
Computer-Adaptive and Paper ASVAB Testing
The ASVAB can be administered using different testing formats.
Computer-Adaptive ASVAB (CAT-ASVAB)
In the computer-adaptive format, the difficulty of subsequent questions can change based on your answers. You generally cannot return to a question after answering it.
Paper-and-Pencil ASVAB
The paper format presents a fixed set of questions. Within the time allowed for a subtest, you can generally review or change your answers.
Both formats include timed sections. Ask your recruiter or testing administrator which version you will take so you can prepare appropriately.
How to Prepare for the ASVAB
- Start with sample questions. Identify which subjects need the most attention.
- Practice mathematics regularly. Review arithmetic, fractions, percentages, algebra, and geometry.
- Improve reading comprehension. Practice identifying main ideas and understanding short passages.
- Build your vocabulary. Study unfamiliar words and their meanings.
- Review technical subjects. Study mechanical, electrical, and automotive fundamentals where needed.
- Practice under timed conditions. Learn to work accurately without spending too long on individual problems.
- Review incorrect answers. Understand why an answer was wrong instead of simply memorizing the correct choice.
- Get adequate rest before testing. Arrive prepared and carefully follow the testing instructions.

Choosing a Military Career
A strong ASVAB performance can expand your potential career options, but test scores are not the only qualification. Medical standards, security clearance eligibility, physical requirements, education, job availability, and service-specific rules can also affect your choices.
Before signing an enlistment contract, discuss your preferred occupations and qualification requirements with your recruiter.
