Navy OAR Test – Ultimate Study Guide + Preparation Tips
Last Updated on May 29, 2022
If you are currently serving in the military and want to become a commissioned officer, then taking the OAR (Officer Aptitude Rating) exam is where you start.
Your high school, college GPA, and general application components along with passing the exam all factor into whether you will get placement.
If you are a civilian who is about to enlist and you want to take the OAR test, you must contact a recruiter who will discuss the next steps in your application process.
Your OAR test score will be used to determine whether you’ll be admitted to Officer Candidate School in the officer training program.
The OAR test is standardized and used to determine your skills and abilities if you want to become an officer in the U.S. military.
The test is a subset of the Aviation Standard Test Battery exam (ATSB-E). You can elect to take the test as one part of the full ASTB-E or on its own.
If you want to apply for the aviation programs you need to take the entire Aviation Standard Test Battery exam.
If you want to apply for separate programs like the Navy Officer Candidate School, then you only need to take the OAR test.
The OAR exam as a subset of the ASTB-E is used by the Navy, Marine Corps, and Coast Guard.
What is the exam like?
The OAR exam is a multiple-choice standardized test that measures your knowledge of math, reading comprehension, and mechanical comprehension.
It is almost the same format as the SAT or ACT exam, but the topics are more technical and in-depth.
You have a choice of two test formats:
You have 85 minutes to complete this test. There are a fixed number of questions in a specific sequence in each subtest.
You will not be penalized for incorrect answers, but any questions left blank will be scored as incorrect. If you don’t know the answer; guess!
This version adjusts the number of questions and their difficulty based on your previous answers.
While you answer the questions, the test automatically modifies the difficulty level of the rest (either up or down), depending on the number of correct answers.
This is a bonus, but if you don’t answer enough questions in the specified time, a penalty is added to your score.
Also, you do not want to guess on this version, but give the correct answer as often as possible, otherwise your score may decrease.
Frequently asked questions:

The OAR exam consists of three subtests that test your core cognitive skills through a series of aptitude tests. These are a math skills test, a reading comprehension test, and a mechanical comprehension test.
- Math Skills Test: OAR math tests your ability to formulate math problems in algebra, arithmetic operations, and geometry. You will also have to answer word problems and equations such as:

The math skills test has 30 questions which you have 40 minutes to complete. Make sure you do as many practice questions as possible before you take the real test.
The math portion of the exam has the most time allotted to answer questions.
Reading Comprehension Test: Here you will be assessed on your reading level and ability to retain and draw conclusions from information. There will be several short passages in the comprehension questions, to read, that range in levels of difficulty.
- The reading comprehension section has 20 questions that you have 30 minutes to complete. You will have to decide how to respond from a group of options applying to each passage.
- There might even be some incorrect response options, but only one response will be the correct answer.
Mechanical Comprehension Test: Here test-takers will be evaluated on their overall understanding of mechanical concepts; focusing a lot on physics.
- More than half of the questions require that you analyze an image to answer them. You have to work quickly here with only 30 seconds to answer each question because you have 30 questions that need answering in 15 minutes!
- In the mechanical comprehension test, some of the questions test you on how well you understand the essential principles of gases and liquids in how they affect velocity, volume, and pressure.
- You need to understand concepts such as the mechanisms of engine components and gears, weight distribution, electricity, pulleys and fulcrums, and operating basic machinery.
What is a good score on the OAR test?
The OAR test is given a cumulative score that ranges from 20 to 80, with the average scores ranging from 40 to 60.
The minimum score required to qualify for an officer training program depends on the branch of the military you are in or want to go into.
The Navy requires a minimum score of 35. As a test taker, you want to prepare well in advance to get a competitive score as the officer training programs have limited available spaces.
Meeting the minimum criteria doesn’t guarantee your admission.
Your exam results are used to determine who are the best possible candidates suited to be officers, and with an acceptance rate of only about 4%; you want your score to be as high as possible!
