The Officer Aptitude Rating (known as OAR) test is a subset of the larger Aviation Standard Test Battery (known as ASTB), administered at Navy Recruiting Districts (NRDs), is used by the U.S. Navy, Marine Corps, and Coast Guard to select officer aviation program applicants. The newest version of the OAR is series E. The ASTB-E test is a multiple-aptitude battery that measures developed abilities and helps predict future academic and occupational success in the military.

The ASTB is a multiple-choice test which consists of 7 subtests.

- Section 1 – Math Skills Test (MST)
- Section 2 – Reading Comprehension Test (RCT)
- Section 3 – Mechanical Comprehension Test (MCT)
- Section 4 – Aviation and Nautical Information Test (ANIT)
- Section 5 – Naval Aviation Trait Facet Inventory (NATFI)

- Section 7 – Biographical Inventory with Response Validation (BI-RV)

But, if you are seeking admittance to non-aviation officer programs, you have the option of taking only the OAR portion of the test.

The OAR is a Computer Adaptive Test (CAT). It means that if the correct answer is chosen, the next question will be harder. If the answer given is incorrect, the next question will be easier. This also means that once an answer is selected on the CAT it cannot be changed.

The Mathematics section of OAR contains 20 to 30 multiple-choice questions assess content in the following areas:

- Number Sense and Operations
