ASTB Test: Introduction
The U.S. Navy, Coast Guard, and Marine Corps use the ASTB (Aviation Selection Test Battery) as their principal exam in the selection of candidates to their respective officer aviation programs. The ASTB has been updated in recent years introducing many technical improvements. These developments have dubbed the exam the series-E, and is now widely referred to as the ASTB-E. However, for simplicity, we will be referring to it still as theAviation Selection Test Battery. However, all information presented refers to the most up-to-date version of the ASTB – the ASTB-E.
If one of your aspirations is to become an officer in the Navy you will need to take the ASTB. Do not underestimate how important this exam is when it comes to your career as an Officer. Your score on theAviation Selection Test Battery will dictate whether or not you meet the standards to go to officer training as well as show your suitability for other military occupations.
The below article as well as other articles on this website will break down the ASTB Test for you, laying out its structure and format, provide a practice test you can use in preparation for the ASTB, show you what the scoring requirements are and what kind of score you should strive for on the ASTB, we will also recommend specific ASTB study guides and let you know which ones we think you should steer clear of, we will also answer the most common FAQ’s when it comes to the ASTB.

ASTB Test Layout
There are 7 sections to the ASTB, see the table below for a complete breakdown of the different sections.
The first 5 sections of the ASTB (The MST, RCT, MCT, ANIT, and NATFI) are all computer adaptive. Meaning each following question is based on your answer to the last.
The first four are multiple choice with 20 to 30 questions in total. A personality inventory makes up the fifth section and is a grouping of 44 pairs of questions.
If you’re not looking to get into aviation but, still want to be an officer you only need to complete the first three sections of the ASTB known as the Officer Aptitude Rating or OAR.
The OAR itself can take up to 2 hours to complete while writing the full version of theAviation Selection Test Battery can take just over 3 hours with the exception of having to complete the BI-RV on your own time preferably, prior to writing the rest of the ASTB.
|Math Skills Test (MST)||Officer Aptitude Rating (OAR)||Aviation Standard Test Battery (ASTB)|
|Reading Comprehension Test (RCT)|
|Mechanical Comprehension Test (MCT)|
|Aviation and Nautical Information Test (ANIT)|
|Naval Aviation Trait Facet Inventory (NATFI)|
|Performance Based Measures Battery (PBM)|
|Biographical Inventory with Response Validation (BI-RV)|
For a more complete explanation of each section please find each described in more detail below:
Aviation Standard Test Battery Section Summaries
Section 1: MST (Math Skills Test): Nothing you probably haven’t seen before in high-school but, it’s definitely worth brushing up on. You’re going to see some basic arithmetic, geometry, algebra, angles, and perimeter, along with the occasional time and distance word problem and potentially some basic probability.
Section 2: RCT (Reading Comprehension Test): Again, really straight forward stuff. You read a passage of text and are given options of sentences only one of which is totally true based on the text given above. Most will seem true but, only one can actually be derived from the provided passage.
Section 3: MCT (Mechanical Comprehension Test): The questions in this section are similar to what would find in an intro to physics class. Brush up on your knowledge of basic physics and how it relates to velocity, volume, and pressure as well as the mechanics of simple machines when it comes to gears, electricity, and weight distribution.
Section 4: ANIT (Aviation and Nautical Information Test): You guessed it! On this section of the ASTB you’re going to need to know some nautical terminology, a little bit of aviation history as well as some principles of aviation like aerodynamic principles, basic aircraft components, and flight rules
Section 5: NATFI (Naval Aviation Trait Facet Inventory): You sort of get off easy here as there’s no real way to prepare for this section. It’s a personality inventory that, in the end, will gauge ones suitability for a career in aviation based on their personal characteristics.
Section 6: PBM (Performance Based Measures Battery): Depending on your tastes this might be the most ‘fun’ part of the ASTB. You basically get to do a flight simulation. You’ll be given a flight mock-up flight console with a throttle and joystick along with a headset. You’ll also get a map that you’ll need to study before guiding an airplane around on a screen. For a more detailed of explanation of this section check out our full-length article of the different sections of the ASTB called ASTB Test Layout.
Section 7: BI-RV (Biographical Inventory with Response Validation): This is the part of the ASTB that you can complete from any computer with an internet connection. It is recommended that you complete this section prior to writing the rest of the ASTB. All it is, is a questionnaire about your previous experiences and successes or achievements with aviation. Like section 5 you really can’t prepare for this section – just answer honestly as there aren’t any real right or wrong responses.

ASTB Test Scores
The scores of the different ASTB sections are then used to create 4 different ratings. These ratings are the AQR, the PFAR, the FOFAR, and the OAR.
AQR stands for Academic Qualifications Rating
PFAR stands for Pilot Flight Aptitude Rating
FOFAR stands for Flight Officer Aptitude Rating
OAR stands for Officer Aptitude Rating and is made up using the first three sections of theAviation Selection Test Battery (the MST, RCT, and MCT). This rating uses a point system and is given a score from 20 to 80 using 1 point increments.
The AQR, PFAR, and FOFAR use what is called a stanine (STAndard NINE) system of rating. This means they are weighted using a scale from 1 to 9 with a mean of 5 and a standard deviation of 2.
See the chart below for the breakdown of each stanine by percentile:
Minimum ASTB Test Scores
Different branches of military occupation and service require differing minimum scores from the ASTB. Consult the table below to see which minimum score is required for each branch:
|Student Naval Aviators (SNA)||4||5||—||—|
|Student Naval Flight Officers (SNFO)||4||—||5||—|
|Marine Pilots and Marine Flight Officers||4||—||6||—|
|Coast Guards and OCS||4||5||—||—|
Keep in mind that minimum scores are just a base line. There are a finite amount of seats available and applicants with the highest ratings will be successful. So although you may achieve the minimum score you need it may still not be good enough. Do your absolute best – strive for the highest score you can possibly get.
ASTB Test Study Guide
After seeing the layout and what’s covered on the ASTB I’m sure you can see how things might be a little tricky when it comes to writing this exam. It’s not that the questions themselves are overly complicated but, that there’s a lot of material and a strict time requirement. Therefore, practicing with the right resources or the right ASTB study guide becomes that much more important.
A quality ASTB study guide truly will be invaluable when it comes to preparing for the ASTB. The right guide will go into the proper amount of detail for each section and help you to learn the pace of the exam so that when you sit down to write it you’re as prepared as possible for the ASTB.
As noted above, the questions themselves are of a simple nature but, when time is of the essence mistakes can be easily made. That’s why using a study guide a head of time will help to familiarize yourself enough that there won’t be any real surprises when you sit down to write the ASTB. Having the right guide and writing a few ASTB practice tests before the actual exam can mean the difference between real success and failure.
