OAR Practice Test

Prepare for your test with realistic questions.

The Officer Aptitude Rating (OAR) test is a subset of the larger Aviation Standard Test Battery (ASTB-E) used by the Navy, Marine Corps, and Coast Guard. Your scores on this test will be used to decide whether you qualify for officer training. It will also be used to help decide which occupation(s) you will be most suited for.

OAR Test Eligibility

The OAR is open to anyone who meets the minimum criteria for applying to the officer training program. In order to apply for officer candidate school, you need to be a US citizen between the ages of 19 and 35, and you need to have your bachelor’s degree.

If you meet those criteria, you can register for the OAR and apply for the officer training program. As part of the application process, you will also undergo a thorough background investigation.

To schedule your exam and learn more about what is involved in the application process, talk to your recruiter. You will be allowed to take the test a maximum of three times in your lifetime. So it is important to schedule an appointment that leaves you with plenty of time to prepare and make sure that you do your best.

OAR Test Outline

As mentioned previously, the OAR test is part of the ASTB-E exam. If you are not interested in an aviation-related occupation, you only need to complete the OAR section of the ASTB-E. The OAR portion will take between 1 and 2.5 hours

OAR Scores

The OAR is given a cumulative score ranging from 20 to 80. Average scores range from 40 to 60. The minimum score you need to aim for in order to qualify for officer training will depend on which branch of the military you are in. For the Navy, for example, you will need a minimum score of 35. It is highly recommended that you aim above this minimum, however.

Many officer training programs are competitive and have a limited number of available spots. Even if you do meet the minimum cutoff, you are not guaranteed admission. The higher your score, the stronger your application will be.

How Computer-Adaptive Testing Works

The OAR test is computer-adaptive. This means that, depending on your performance, the difficulty of your test may increase or decrease as you go on. Here’s a look at how it works:

A flowchart that shows the adaptive nature of the exam

The test starts with a section judged to be of medium difficulty, and depending on your performance, the next section may be easier or harder. If you do well in the first section, the second section will be harder; conversely, if you do poorly on the first section, the second section will be easy.
