What Is the ASVAB Test and What Is It Used For?

What is the ASVAB test exactly? The

Armed Services Vocational Aptitude Battery (ASVAB)

is a timed, multiple-choice test developed by the US Department of Defense.

It measures your potential for academic and occupational success in the military

and is also used to determine what types of military jobs would be best suited to you based on your own individual strengths.

The ASVAB was introduced in 1968. Since then, more than 40 million people have taken it.

Currently, the ASVAB test consists of

four domains


  • Verbal
  • Math
  • Science and Technical
  • Spatial

These concepts are tested across 10 subtests

, covering a mix of broad and niche topics, such as General Science, Mechanical Comprehension, and Auto Information.

There are two versions of the ASVAB:

  • The enlistment ASVAB
  • The ASVAB Career Exploration Program (CEP)


enlistment ASVAB

is used only for recruiting purposes and is usually administered at a Military Entrance Processing Station (MEPS) or a satellite location (if you don’t live near a MEPS) known as a Military Entrance Test (MET) site.

The test’s primary purpose is to determine your eligibility for military enlistment.



, however, is given to high school students in grades 10 to 12 and first- and second-year college students to

help them figure out what career paths—military and civilian—could be ideal matches for them

based on their strengths. This ASVAB version is typically administered at high schools and colleges. Note that you are


making any commitment to military service

if you take the ASVAB CEP.


What’s the Format of the ASVAB?

As mentioned above, the ASVAB is a timed, multiple-choice test that contains four domains (Verbal, Math, Science and Technical, and Spatial) across 10 subtests.

The following table comes from the

official ASVAB website

and gives an overview of the content on each subtest. All subtests are arranged in the order in which they appear on the ASVAB.

ASVAB Subtest



General Science (GS)

Knowledge of physical and biological sciences


Arithmetic Reasoning (AR)

Ability to solve arithmetic word problems


Word Knowledge (WK)

Ability to select the correct meaning of a word presented in context and to identify best synonym for a given word


Paragraph Comprehension (PC)

Ability to obtain information from written passages


Mathematics Knowledge (MK)

Knowledge of high school mathematics principles


Electronics Information (EI)

Knowledge of electricity and electronics


Auto Information (AI)*

Knowledge of automobile technology


Shop Information (SI)*

Knowledge of tools and shop terminology and practices


Mechanical Comprehension (MC)

Knowledge of mechanical and physical principles


Assembling Objects (AO)**

Ability to determine how an object will look when its parts are put together


*AI and SI are combined into one score (labeled AS)

**The ASVAB CEP does not have the AO subtest

The ASVAB test can be taken

either on a computer or on paper


The computer ASVAB, or CAT-ASVAB, is


, meaning that it adapts to your own abilities. So if you get a question right, the next question will be harder. Likewise, if you get a question wrong, the next question will be easier.

There is a penalty for guessing on the computer ASVAB

, so try your best to avoid random guessing. The CAT-ASVAB is the version most often administered at MEPS.

The paper and pencil ASVAB, or P&P-ASVAB as it’s known, is normally administered at MET satellite sites and is not adaptive as the CAT-ASVAB is. Unlike the computer ASVAB, the paper test

does not have a penalty for guessing


The two formats of the ASVAB—computer and paper—have the same overall content but

differ in length and the number of questions

, as you can see in this comparison table:

*AI and SI are administered as one section (AS) on the paper test

The computer ASVAB is slightly longer at just over two and a half hours. But this is really just the time limit you have—as the official ASVAB site notes,

most test takers finish the CAT-ASVAB a lot faster than this


“You are allowed to complete the CAT-ASVAB at your own pace. … [M]ost examinees finish the test before the time limit is reached. The average examinee takes about 1 1/2 hours to complete the CAT-ASVAB.”

Also, since the computer ASVAB adapts to your ability, it’s possible you’ll

get fewer questions on some of the subtests

, thereby making your computer ASVAB shorter than the paper ASVAB.


How Is the ASVAB Scored?

The ASVAB scores you get will differ depending on whether you’re taking the enlistment ASVAB for the military


the ASVAB CEP for general career exploration.

How Is the Enlistment ASVAB Scored?

You’ll get a

Standard Score

on each of the subtests for the enlistment ASVAB. With these scores, 50 is average and 60+ is above average. Your subtest Standard Scores are then combined to give you various

composite scores

, which tell you what kinds of military jobs you’re best suited for.

But the score that’s most important will be your

Armed Forces Qualification Test (AFQT) score

, which is the combination of your scores on the following four subtests:

  • Arithmetic Reasoning
  • Mathematics Knowledge
  • Paragraph Comprehension
  • Word Knowledge

Your AFQT score

determines your

eligibility for enlistment

in different branches of the military, such as the Army, Navy, Air Force, Coast Guard, and Marine Corps. It uses a

scale of 1 to 99

; these are the


of test takers.

So for example, if you got a 68 AFQT score, this would mean you scored in the 68th percentile (i.e., you did as well as or better than 68% of test takers).

While there is no passing or failing the ASVAB, those hoping to be eligible for enlistment will

need to meet the minimum threshold for that branch of the military

. Typically, this means you will have to score in

at least

Category IIIB (see chart below).

AFQT Category

Score Range


















Official ASVAB

If you have a GED instead of a high school diploma, you’ll

need to have a higher AFQT score

to be eligible for enlistment (exact score reqs vary among military branches). Your results will be valid for

two years

from the date of administration, giving you plenty of time to decide whether the military is right for you.

How Is the ASVAB CEP Scored?

With the ASVAB CEP, you’ll also get an AFQT score; however,

you’re not making any commitment to enlisting in the military


Besides the AFQT score and your individual subtest scores, you’ll get

Career Exploration Scores

, which are unique to the ASVAB CEP. These scores cover three domains, each of which consists of scores from specific subtests:

  • Verbal (Word Knowledge, Paragraph Comprehension)
  • Math (Arithmetic Reasoning, Math Knowledge)
  • Science/Technical (General Science, Electronics Information, Mechanical Comprehension)

Career Exploration Scores are given to you as both percentiles and Standard Scores, and tell you

what kinds of careers you’re best suited for based on your performance on the test


Here’s a helpful video created by the ASVAB CEP with more information on how scoring works:

How Can You Register to Take the ASVAB?

For the enlistment ASVAB, you’ll need to contact a military recruiter and schedule an appointment to take the ASVAB at either a nearby MEPS or MET site. Go to

Today’s Military

to request info from the military branch you’re interested in and to get in touch with a recruiter.

The recruiter will first determine whether you are qualified to take the ASVAB test and then, if you are, help you set up an appointment to take it.

Factors that could contribute

to your being unable to test are as follows:

  • Age (too young or too old)
  • Too many dependents
  • Medical problem
  • Drug usage
  • Criminal history

With the enlistment ASVAB,

you can retake it one month after your first attempt, one month after your second attempt, and six months after your third attempt


If you’re a high school or college student who is interested in taking the ASVAB CEP, you’ll have to

contact your teacher or counselor directly

about taking the ASVAB test at your school.

On the day you take the ASVAB test, you must arrive on time and bring

valid identification

. Your recruiter might drive you to and from the testing center; however, they are not allowed inside the testing room.


Key Takeaways: So What Is the ASVAB Test?

The ASVAB, or Armed Services Vocational Aptitude Battery, is a multiple-choice exam consisting of 10 subtests. It was designed by the US Department of Defense to determine test takers’

potential for academic and occupational success

in both the military and in specific military jobs.

There are two versions of the ASVAB test:

  • Enlistment ASVAB, which is given only to those wishing to enlist in the military
  • ASVAB Career Exploration Program, or ASVAB CEP, which is administered to high school and college students to help them identify potential career paths

The ASVAB tests a variety of topics across four domains:

  • Verbal
  • Math
  • Science and Technical
  • Spatial (

The exam can be taken either on the computer or on paper; usually, this depends on where you’re taking the ASVAB test (for example, MEPS tend to offer the computer version).

On the enlistment ASVAB, the most important score you’ll get is

your Armed Forces Qualification Test (AFQT) score

, which is based on the scores you earned from four specific subtests (Arithmetic Reasoning, Mathematics Knowledge, Paragraph Comprehension, and Word Knowledge) and uses a scale of 1-99 (these are actually



Though there’s no passing or failing the ASVAB,

the minimum score needed for enlistment will vary depending on what branch of the military you’d like to join

. Generally speaking, though, you’ll need an AFQT score in at least Category IIIB (so 31+).

To register for the enlistment ASVAB, you must contact a military recruiter who will check that you meet all the basic qualifications for enlistment before you are allowed to take the test. To register for the ASVAB CEP, you’ll need to reach out to your teacher or counselor and ask about getting the ASVAB administered at your school.

This is all the basic information to know about the ASVAB. Now, here’s to hoping you get the score you want on it!
