What Is the ASVAB?

The Armed Services Vocational Aptitude Battery (ASVAB) is a series of aptitude tests developed by the Department of Defense. It is used to determine and predict the potential/future success of military candidates. The ASVAB military entrance exam is a part of the U.S. Military screening process and is administered annually to more than one million military applicants.


ASVAB Test Content and Format

The ASVAB is administered at a Military Entrance Processing Station (MEPS). If there is not a MEPS near you, you may take the ASVAB at a satellite location called a Military Entrance Test (MET) site. There are two formats of the ASVAB: computer-administered test (CAT) and paper and pencil (P&P). All MEPS administer the CAT-ASVAB, while MET sites administer the P&P ASVAB.

No matter in which format you take the ASVAB, your scores should be very similar. Learn more about the ASVAB test scores.


Computer-Administered Test (CAT-ASVAB)

The CAT-ASVAB has a total of 145 questions with a time limit of 154 minutes. The CAT-ASVAB test questions are computer-adaptive, meaning that they either increase or decrease in difficulty level based on your responses to previous questions. The questions, therefore, are tailored to each test taker’s ability. There is a penalty for wrong answers on this exam, so guessing is not to your advantage. The time of test completion depends on your individual speed. If you finish a section before the allotted time, you can move forward to the next without waiting for the other test takers.


Paper-and-Pencil (P&P ASVAB)

The P&P ASVAB has a total of 225 questions with a time limit of 149 minutes. The written ASVAB test questions contain the same content as the computer-administered version, but in the paper-and-pencil version, all test takers are given the same questions regardless of ability and knowledge. On this version of the test there is no penalty for wrong answers and it is to your advantage to eliminate unlikely choices and make an educated guess if you are unsure of the answer.

The ASVAB tests are designed to measure aptitudes in four domains: Verbal, Math, Science & Technical, and Spatial. The table below describes the contents of the ASVAB tests. The tests are presented in the order in which they are administered.

Sub-test Description Domain
General Science Knowledge of physical and biological sciences Science/Technical
Arithmetic Reasoning (AR) Ability to solve arithmetic word problems Math
Word Knowledge (WK) Ability to select the correct meaning of a word presented in context and to identify the best synonym for a given word Verbal
Paragraph Comprehension (PC) Ability to obtain information from written passages Verbal
Math Knowledge (MK) Knowledge of high school mathematical principles Math
Electronic Information (EI) Knowledge of electricity and electronics Science/Technical
*Auto Information (AI) Knowledge of automobile technology Science/Technical
*Shop Information (SI) Knowledge of tools and shop terminology & practices Science/Technical
Mechanical Comprehension (MC) Knowledge of mechanical and physical practices Science/Technical
Assembling Objects (AO) Ability to determine how an object will look when its parts are put together Spatial

*The Auto Information and Shop Information sub-tests are separate tests on the CAT-ASVAB, but scores as a single test (AS). On the P&P version, they are combined into one sub-test called AS.

About the Military

The military is also referred to as the U.S. Armed Forces. It is made up of the five armed service branches: Air Force, Army, Coast Guard, Marine Corps, and Navy. The Secretary of the Department of Defense (DoD) has control over the military and each branch - except the Coast Guard, which is under the Dept. of Homeland Security.

Each branch of the military has a unique mission within the overall mission of U.S. security and peace.

  • Air Force - The nation's source of air and space power. The primary mission of the USAF is to fly planes, helicopters, and satellites.
  • Army - The dominant land power. The Army generally moves in to an area, secures it, and instills order and values before it leaves. It also guards U.S. installations and properties throughout the world.
  • Coast Guard - The Coast Guard's mission is primarily with domestic waterways. The Coast Guard does rescues, law enforcement, drug prevention, and clears waterways.
  • Marine Corps - The Marine Corps is known as the U.S.' rapid-reaction force. They are trained to fight by sea and land.
  • Navy - The Navy accomplishes its missions primarily by sea, but also by air and land. It secures and protects the oceans around the world to create peace and stability, making the seas safe for travel and trade.
