Question 1

What is the ASVAB exam?

Accepted Answer

The ASVAB (Armed Services Vocational Aptitude Battery) is a multiple-aptitude test required for enlistment in all U.S. military branches. It consists of 10 subtests covering verbal, math, science, and technical skills. The CAT-ASVAB (computerized) has 145 questions in 154 minutes, while the paper version has 225 questions in 149 minutes.

Question 2

What ASVAB score do I need to join the military?

Accepted Answer

Minimum AFQT scores vary by branch: Army, Marines, and Navy require 31, Air Force and Space Force require 36, and Coast Guard requires 40. Having a GED instead of a high school diploma typically requires higher scores (around 50-65). Higher scores also qualify you for more job options.

Question 3

What is the AFQT score and how is it calculated?

Accepted Answer

The AFQT (Armed Forces Qualification Test) score is calculated from four ASVAB subtests using the formula: AFQT = 2VE + AR + MK, where VE (Verbal Expression) = Word Knowledge + Paragraph Comprehension. It's reported as a percentile (1-99) comparing you to a reference population of 18-23 year olds.

Question 4

Can I use a calculator on the ASVAB?

Accepted Answer

No, calculators are not allowed on any version of the ASVAB. You'll be provided with scratch paper for calculations. This makes it essential to practice mental math, estimation, and basic arithmetic operations without a calculator.

Question 5

How long are ASVAB scores valid?

Accepted Answer

ASVAB scores remain valid for 2 years for military enlistment purposes. If your scores expire before enlisting, you'll need to retake the test. You can retake the ASVAB after 1 month for your first two attempts, then must wait 6 months for additional retakes.
