ASVAB Structure

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. If you do not live near a MEPS, the ASVAB can be administered at a satellite location called a Military Entrance Test (MET) site. The ASVAB is administered by computer at the MEPS while a paper-and-pencil version is given at most MET sites. Testing procedures can vary depending on the method of administration.
