What it is
The ASVAB (Armed Services Vocational Aptitude Battery) is a free aptitude test used by the U.S. military for enlistment eligibility and job (MOS) placement. It's also given in many high schools through the Career Exploration Program as a career-interest and aptitude tool — with no obligation to enlist. It measures skills across math, verbal, science, and technical areas.
Format & structure
The ASVAB has 10 subtests — including Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, plus technical areas like Electronics, Auto & Shop, Mechanical Comprehension, and General Science. It's given as a computer-adaptive test (CAT-ASVAB) at military processing stations, or on paper in schools.
How it's scored
Four subtests (Arithmetic Reasoning, Math Knowledge, Word Knowledge, Paragraph Comprehension) combine into the AFQT score — a percentile (1–99) that determines enlistment eligibility (each branch sets a minimum). The other subtests feed composite scores that qualify you for specific military jobs. In the school program, results come with career-exploration tools.
Registration & cost
You don't register the usual way: for enlistment, a military recruiter arranges the ASVAB at a testing site (free). For the school program, your high school schedules it. There's no cost either way.
Test dates & timing
Enlistment ASVABs are scheduled through a recruiter as needed; the school version is given on dates your school sets. Scores are typically available quickly (immediately for the computer version).

How scores are used
For enlistment, the AFQT sets eligibility and the composite scores determine which military jobs you qualify for. In the school program, results are a career-exploration tool — students and counselors use them to explore fit, with no obligation to join. Scores are generally valid for two years for enlistment.
Accommodations & support
Accommodations for documented disabilities may be available in the school program; the enlistment ASVAB has specific standardized conditions — ask your recruiter or school counselor.
