The Officer Aptitude Rating (OAR) is a portion of the larger Aviation Selection Test Battery (OAR-E) test. The OAR-E measures candidate’s verbal and quantitative ability, mechanical understanding, spatial awareness, and knowledge of general aviation concepts. The OAR includes only the portions of the OAR-E that cover verbal and quantitative abilities and mechanical understanding.

The OAR-E is used to determine eligibility of college graduates desiring to become an aviation officer (pilot and first officer) in the US Navy, Marine Corps, or Coast Guard. Individuals applying for nonaviation officer programs, such as Officer Candidate School (OCS), may only be required to take the OAR portions of the test.

The OAR-E is developed and monitored by the Naval Operational Medicine Institute (NOMI). The Educational Testing Service collaborated with NOMI to produce the exam in paper and computer adaptive test formats. The Naval Personnel Command and Commandant of the Marine Corps establish eligibility requirements.


There is a three-time lifetime limit to attempt the OAR-E. If a candidate wishes to retest, the date of retest must be no earlier than thirty-one days after the date the initial exam was taken. If a second retest is desired, the candidate may retest not earlier than ninety-one days after first retest.

Exam results of candidates who previously took the OAR-E (Form 1 through Form 5) do not count toward the three-time lifetime limit; however, those results remain valid until another OAR-E is taken.

Individuals who took the OAR-E for an OAR only may return within thirty days of the initial test to complete the OAR-E by taking the remaining subtests. This is called a test merge. In this case, candidates must wait until the OAR score is received prior to taking the remaining subtests. Additionally, even if the OAR portion was taken by paper format, the remaining test must be conducted using the CAT format. The date the candidate completes the remaining subtests is considered the official test date toward the three-time lifetime limit.


If you are ready to take the OAR portion of the OAR-E, contact your local recruiter. Your recruiter will determine your initial qualifications and schedule you to take the OAR-E. The location where you take the OAR-E will be decided when a test seat is available. Possible testing locations include Navy recruiting stations, NROTC units at selected universities, Marine Corps officer selection offices, and military institutes.

On the day of the exam, you will need to bring an identification card and your Social Security card to verify your identity. Testing materials are provided by the test proctor. Calculators are not allowed. If your recruiter drives you to the testing location, the recruiter cannot be in the testing room. Personal breaks are scheduled by the proctor, so be prepared to remain in the testing seat until dismissed.

To help you prepare for your OAR test, we have developed a list of 30 test-taking tips that have been shown to be very helpful for students of all ages and backgrounds when taking standardized tests. They cover everything. from what to do the night before the big day, to what to eat for breakfast, to thoughts on how to handle your caffeine to tips you can use during the actual exam.

Our first set of tips focus on what you can do the night before to help you prepare for the day of your OAR exam.

1. Study hard for the OAR exam with our OAR practice test in the days before the exam but take it easy the night before and do something relaxing rather than studying and cramming. This will help decrease anxiety, allow you to get a better night’s sleep, and be more mentally fresh during the big exam.

2. Pack your bag or lay out your essentials the night before. Make sure to include at least two forms of ID, your admission ticket or confirmation, pencils, a high protein, easy-to-eat snack, bottled water, and any necessary medications.

3. Map out your route to the test center the night before. If you are driving, take traffic into account, especially if you are driving during rush hour.

4. Spend the hour before bed avoiding television, your computer, cell phone, or social media. The bright screens and overload of data can keep your brain buzzing come bedtime.

Once you’ve taken all the necessary steps you can to be prepared for exam day, our next group of tips will help you concentrate on how to get your best night’s sleep, which is critical to being sharp and alert during your OAR exam.

5. Make sure you give yourself your usual amount of sleep, preferably at least 7-8 hours. You may find you need even more sleep. Pay attention to how much you sleep in the days before the exam, and how many hours it takes for you to feel refreshed.

6. Set your alarm early enough that you have plenty of time to have a well-balanced breakfast and avoid rushing in the morning to get ready.

7. Don’t use sedatives like Benadryl or NyQuil to fall asleep. These medications often remain in your body long after you have taken them, meaning you will still be drowsy during the exam and potentially up to 24 hours after taking them.

8. With all the extra adrenaline flowing through your bloodstream the night before a big test, it is not uncommon to feel more anxiety than usual. Focus on thinking positive thoughts, which will decrease this anxiety, help you relax and fall asleep.

Now that you’re ready to get a full night’s sleep, here are some great tips to help you get through the morning and those critical hours before the big exam.

9. Don't forget to take any vitamins or medications you would usually take in the mornings before you leave for the test center. It is important that you keep your body – and schedule – as normal as possible to ensure you are calm and collected come test-taking time.

10. Dress in loose, comfortable clothes and wear layers. Also, wear comfortable and breathable shoes. Although you will be seated, you don't want tight, restrictive clothing to serve as a distraction.

11. Many testing locations keep their air conditioner on high. You want to remember to bring a sweater or jacket in case the test center is too cold, as you never know how hot or cold the testing location could be.

12. Eat a breakfast with protein, fiber and good fats, such as eggs, avocado, oatmeal, whole-grain toast, berries, or nuts - all of which keep you full longer and your brain healthy.

13. Use caffeine as you normally would, and as sparingly as possible. Coffee, energy drinks, tea, chocolate and many soft drinks all contain caffeine. Therefore, be smart about what you put into your body. Just as with high carb or high sugar drinks and foods, many people tend to crash 3 to 4 hours after ingesting caffeinated products.

14. Bring an energizing snack to leave in your bag that doesn’t require refrigeration and isn’t messy or difficult to eat.Bring water, not sugary soda or sports drinks.

15. If you find that you have extra time and have made flashcards or a “cheat sheet” while studying, go through the high-yield subjects, as well as ones you might be struggling with.

16. Consider asking a friend or family member to take you to the testing location so you can continue to review your materials, not stress about transportation, and receive the extra moral support they can provide.

17. Aim to get to the test center at least 15-30 minutes early. This gives you time to adjust for several negative scenarios, such as bad traffic, a train, getting lost, lack of parking, or running into issues with your registration, for example.

18. Bring at least two pens and two pencils with good erasers, a calculator with new batteries and any other resources that your instructor allows you to take into the exam room. Make sure you clear any materials you are bringing in with the instructor first – you don’t want to be removed from the exam or have your exam forfeited because you broke an easy to avoid rule.

19. Bring a watch to the test so that you can better pace yourself. In the days leading up to the OAR exam, consider using the watch to help time yourself so you grow accustomed to the amount of time it takes you to answer a question – as well as the amount of time you can realistically spend on a problem. If you use a digital watch, make sure it is permitted in the testing room.

20. Consider packing helpful healthcare products you might need in the case of an emergency, such as pain relievers like ibuprofen or acetaminophen.

21. If you can't study or review your materials because you're at the testing location, waiting for the exam to begin, or simply because of nerves, try meditating or focusing on your breathing.

22. Even if you don’t feel like it, use the restroom before entering the exam room. You don't want to waste time worrying about your bodily needs during the test. Furthermore, you can splash water on your face to help perk yourself up.

Once you’re ready for the big moment – exam time itself – you’re going to need to stay focused and choose your answers quickly and wisely. Our final exam tips cover what you can do while you are taking the OAR test itself to raise your score.

23. Multiple studies have shown that individuals work harder and do better work when they’re slightly cold. While you don’t want to be uncomfortably cold – remember, always bring a jacket, just in case – being slightly cold will keep you alert and awake.

24. Don't pay attention to others around you. Don’t worry if someone seems to be going through the test much faster or slower than you. If someone around you is being loud or disruptive, asked to be moved.

25. Go with your gut when choosing an answer. Statistically, the answer that comes to mind first is often the right one. This is assuming you studied the material, of course, which we hope you have done if you read through one of our books!

26. For true or false questions: if you genuinely don't know the answer, mark it true. In most tests, there are typically more true answers than false answers.

27. For multiple choice questions, read ALL the answer choices before marking an answer, even if you think you know the answer when you come across it. You may find your original “right” answer isn’t necessarily the best option.

28. Look for key words: in multiple choice exams, particularly those that require you to read through a text, the questions typically contain key words. These key words can help the test taker choose the correct answer or confuse you if you don’t recognize them. Common keywords are: most, during, after, initially, and first.

29. Narrow answers down by using the process of elimination: after you understand the question, read each answer. If you don’t know the answer right away, use the process of elimination to narrow down the answer choices. It’s usually easy to identify at least one answer that isn’t correct.

30. Don't stay on a problem that you are stuck on, especially when time is a factor. Mark it, skip it and come back to it later once you’ve finished all the easier problems. Not only will this prevent you from wasting time, you may also find that you are able to approach the problem differently after some time away from it. If you are still stuck, return to: 1) Using the process of elimination, and 2) Going with your gut to choose your final answer.

 We hope that these test-taking tips will help you do your best on exam day. For tips specific to the OAR test, make sure you carefully read through our study guide.
