The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple choice test, administered by the United States Military Entrance Processing Command, used to determine qualification for enlistment in the United States Armed Forces. It is often offered to American high school students when they are in the 10th, 11th and 12th grade, though anyone eligible for enlistment may take it.

Although the test is administered by the military, it is not (and never has been) a requirement that a test-taker with a qualifying score enlist in the armed forces.

The ASVAB currently contains 10 sections (except the written test, which contains 9 sections). The duration of each test varies from as low as ten minutes up to 36 minutes for Arithmetic Reasoning; the entire ASVAB is three hours long. The test is typically administered in a computerized format at Military Entrance Processing Stations, known as MEPS, or at a satellite location called a Military Entrance Test (MET) site. The ASVAB is administered by computer at the MEPS, while a written version is given at most MET sites. Testing procedures vary depending on the mode of administration.
