The Armed Services Vocational Aptitude Battery, or ASVAB, is a series of tests developed by the Department of Defense that are used by the U.S. Army to determine whether you’re eligible to enlist. The ASVAB is also used to help determine which jobs you qualify for. The ASVAB Challenge is designed to help you become comfortable with the format of the ASVAB, practice answering questions within the time limits of the tests, and understand the kinds of questions you’ll encounter on the ASVAB.
