What Is the ASVAB Air Force Test?
Each part of the military has its own ASVAB test. As with all ASVAB tests, the Air Force ASVAB is an ability test that assesses the applicant’s skills and knowledge against key characteristics for jobs in the Air Force.
Successful completion of the Air Force ASVAB will result in a contract being offered.
Getting a high score on the ASVAB will make you eligible for more jobs within the Air Force.
There are three types of Air Force ASVAB:
- CAT-ASVAB
- Paper-and-pencil ASVAB
- PiCAT
Each of these tests differs in format, but they are all timed and consist of multiple-choice answers.
The aptitudes and knowledge assessed in these tests fall under four domains. The test is broken down into subsections that assess each of these primary abilities:
- Verbal
- Science and technical
- Math
- Spatial
The CAT-ASVAB
The CAT-ASVAB is a computerized version of the test.
Applicants sit this test at a military processing station or a military entrance test site, depending on which is closest to where they live. It is proctored, that is, somebody will watch those sitting the tests.
The test is timed and consists of adaptable questions. This means that the questions are dependent on how well a candidate is performing on the test. If a candidate is doing well, the subsequent questions will get more challenging.
The CAT-ASVAB usually takes around two hours in total. Once a candidate has finished one section of the test, they can move on to the next section. After submitting an answer to a question, it is not possible to go back and change your answer.
Also included in some subsections of the test are ‘try-out’ questions.

ASVAB: Paper and Pencil Version
The paper-and-pencil ASVAB is similar to the computerized ASVAB but, as is clear by the name, you use paper and pencil. This test differs from the CAT-ASVAB because the questions are set and not adaptable (they don’t increase or decrease in difficulty).
Candidates can return to any questions they have missed out or want to re-check.
This test is also a proctored test and takes around three to four hours to complete.
The PiCAT ASVAB
The PiCAT differs from both the computerized and paper-and-pencil versions of the ASVAB in that it is not proctored. Applicants can take the test from any location, such as their home.
If an applicant decides to sit a PiCAT Air Force ASVAB, they will need to sit a verification test which lasts around 20 minutes.
This ensures that when applicants sit the PiCAT, the Air Force can be sure it is the applicant sitting the test and not someone else taking the test on their behalf.
The types of questions vary according to whether a candidate is sitting the CAT-ASVAB or the paper-and-pencil ASVAB. The test is split into 10 subsections.
General Science
The General Science subset falls under the Science and Technical domain.
There are 15–30 questions (depending upon the number of try-out questions) in this subset for the CAT-ASVAB. The paper-and-pencil ASVAB has around 25 questions.
All questions relate to science as a whole. Topics asked could include but are not limited to temperature, gases or the human body.
Example Questions
1. What temperature would water boil at if being measured in Fahrenheit?
a) 212 F
b) 100 F
c) 0 F
d) 200 F
The correct answer is: a) 212 F
