ASVAB Frequently Asked Questions

The Armed Services Vocational Aptitude Battery (ASVAB) is a multi-aptitude test administered by the United States Military Entrance Processing Command (USMEPCOM). It measures developed abilities and helps predict future academic and occupational success in the military.

The test is used for two primary purposes:

• Enlistment qualification: Your AFQT score determines if you qualify to enlist
• Job assignment: Your composite scores determine which military occupational specialties (MOS) you qualify for

The number of questions depends on which version you take:

• CAT-ASVAB (computer): 135 scored questions across 10 subtests; 197 minutes of official subtest time without tryout items. Some forms add unscored tryout items and extra time.
• P&P-ASVAB (paper): 225 questions across 9 subtests, 149 minutes of subtest time

The CAT-ASVAB is the most common version, taken at Military Entrance Processing Stations (MEPS). It adapts question difficulty based on your performance.

The CAT-ASVAB administers 10 subtests. FreeASVAB currently combines AI and SI into one Auto & Shop practice category:

• General Science (GS) - Physical and biological sciences
• Arithmetic Reasoning (AR) - Word problems and applied math
• Word Knowledge (WK) - Vocabulary and word meanings
• Paragraph Comprehension (PC) - Reading comprehension
• Mathematics Knowledge (MK) - Algebra and geometry
• Electronics Information (EI) - Electrical concepts and circuits
• Auto Information (AI) - Automobile technology
• Shop Information (SI) - Tools, shop terminology, and practices
• Mechanical Comprehension (MC) - Mechanical principles and physics
• Assembling Objects (AO) - Spatial reasoning and assembly

The CAT-ASVAB (Computer Adaptive Test) is taken at MEPS on a computer. It adapts question difficulty based on your answers - correct answers lead to harder questions, incorrect answers lead to easier ones. It has fewer questions but is more precise.

The P&P-ASVAB (Paper-and-Pencil) is given at schools and MET sites. All test-takers receive the same questions regardless of performance. It has more questions and a fixed time limit per section.

Both versions measure the same aptitudes and produce equivalent scores for enlistment purposes.

The AFQT (Armed Forces Qualification Test) score is the most important ASVAB score. It's calculated from four subtests:

• Arithmetic Reasoning (AR)
• Mathematics Knowledge (MK)
• Word Knowledge (WK)
• Paragraph Comprehension (PC)

The formula is: AFQT = AR + MK + (2 × VE), where VE (Verbal Expression) is derived from WK and PC scores. The raw score is then converted to a percentile ranging from 1-99.

A "good" score depends on your goals:

• 31-35: Minimum qualifying score for most branches
• 50+: Opens up many job opportunities across all branches
• 70+: Qualifies for most technical and specialized roles
• 85+: Excellent - qualifies for virtually all military jobs
• 90+: Top 10% - may qualify for special programs and bonuses

The average ASVAB score is 50 (by definition, since it's a percentile). Scoring above 50 means you performed better than half of all test-takers.

ASVAB scores are valid for 2 years from the date you took the test. After 2 years, you must retake the ASVAB if you want to enlist.

If you've already entered the Delayed Entry Program (DEP), your scores remain valid throughout your DEP period even if the 2-year window expires.

Each MOS has specific composite score requirements (also called line scores). These are calculated from different combinations of ASVAB subtests. For example:

• Army Combat (CO): AR + CS + AS + MC
• Army Electronics (EL): GS + AR + MK + EI
• Navy Nuclear Field: AR + MK + EI + GS ≥ 252

Your recruiter can provide the specific composite score requirements for your desired job. See score requirements by branch →

An effective ASVAB study plan includes:

• Take a diagnostic test to identify your weak areas
• Focus on AFQT sections first (AR, MK, WK, PC) since these determine enlistment eligibility
• Practice regularly with timed practice tests to build test-taking stamina
• Review mistakes to understand why you got questions wrong
• Study 4-8 weeks before your test date for best results

The ASVAB covers high school-level material, so the content itself isn't exceptionally difficult. However, the challenge comes from:

• The breadth of subjects covered across 10 official CAT-ASVAB subtests
• Time pressure on each section
• The adaptive nature of the CAT-ASVAB (questions get harder as you answer correctly)
• Technical sections (Electronics, Mechanical) if you lack background knowledge

With proper preparation, most people can achieve qualifying scores. See our ASVAB tips →

Yes, you can retake the ASVAB. The retake policy is:

• First retest: Wait at least 1 month after your initial test
• Second retest: Wait at least 1 month after your first retest
• Additional retests: Wait at least 6 months between each subsequent retest

Your most recent score is the one that counts for enlistment, even if it's lower than a previous score. There's no limit to the total number of times you can retake the ASVAB.

Yes, recruiters have access to your complete ASVAB testing history through the USMEPCOM system. They can see all previous scores and test dates. However, only your most recent valid score is used for enlistment purposes.

Current public recruiting guidance is more nuanced than one universal table:

• Army: standard public benchmark 31; preparatory pathways may apply below that level
• Marine Corps: 31 for high-school diploma applicants; 50 for GED/nontraditional credentials
• Air Force: 31 for high-school seniors/graduates; 50 for GED holders
• Coast Guard: 32 on its current public enlistment page
• Navy: qualifying standards plus current Future Sailor Preparatory Course pathways; verify your current threshold
• Space Force: qualifying ASVAB score plus career-specific aptitude requirements; verify current accession policy

Education credentials, preparatory programs, waivers, component, and recruiting policy can change eligibility. Confirm your case with an official recruiter.

Absolutely. A higher ASVAB score opens significantly more career opportunities:

• More MOS/rating options across all branches
• Access to technical and intelligence roles
• Potential enlistment bonuses for high-demand jobs
• Better positioning for special programs (e.g., Nuclear Field, Linguist)
• More leverage in negotiating your contract

For the ASVAB at MEPS, bring:

• Valid photo ID (driver's license, passport, or school ID)
• Social Security card
• Documents your recruiter specified

You do NOT need to bring pencils, calculators, or scratch paper - these are provided or not allowed. Calculators are not permitted on the ASVAB.

No. Calculators are not allowed on any version of the ASVAB. You'll need to do all calculations by hand or mentally. This is why practicing mental math and estimation skills is important.

Scratch paper is provided for the paper version. The CAT-ASVAB has an on-screen scratch pad feature.

Testing time varies by version:

• CAT-ASVAB: About 2.5 hours of actual testing time
• P&P-ASVAB: About 3 hours of actual testing time

However, plan for a full day at MEPS. The total visit includes check-in, briefings, the test itself, breaks, and potentially a physical exam. Most people spend 6-8 hours at MEPS.
