The Transportation Security Authority Computer Based Test, which can also be referred to as the Transportation Security Officer Computer Based Test (TSA CBT), is one of the early obstacles in the TSA hiring process. The TSA uses the results of the TSA testing to easily parse out quality candidates. A poor score on the TSA CBT will prevent you from moving on to the next stage in the application process.

What Is the Transportation Security Administration (TSA) Exam?

The Transportation Security Administration Written Exam, often referred to as the TSA Exam, is the test applicants are required to take during their application process as TSA inspector, manager, or Transportation Security Officer. The TSA test evaluates your competency with object recognition, screener awareness, and English language.


What Topics Are on the TSA Computer-Based Test (CBT)?

There are two components of the TSA's CBT: Image Interpretation or the X-Ray Test, and the Written Skills Assessment.


What Is on the TSA X-Ray Test?

The X-Ray test, also known as the Object Recognition Test, the is the more difficult of the two sections included in the TSA CBT test. We are here to answer for you some common FAQs. The more you know about the test going in the more confident you will feel on the test day. The most important thing is that you feel confident going into the test.

The X-Ray test is the more difficult of the two assessments, primarily because this is content unique to the position. On the image interpretation test (also called "baggage scanner training" and the Object Recognition Test or ORT), you will be shown images of baggage that have gone through the X-Ray machine. You will be given only a few seconds to review the baggage and identify target objects. The target items will be forbidden items such as; weapons, bottles, shoes, drugs, or electronics. You will need to decide whether to pass, alarm, or hold a bag due to its content. If you pass the baggage, you decided the bag does not contain any harmful items. If you select alarm, you have indicated that the item has a prohibited item and you request police intervention. If you hold an item, you have identified a prohibited item which requires intervention by a TSO officer and further screening such as; physical search or use of Explosive Trace Technology (ETD).

What Is the Format of the X-Ray Test?

In the TSA X-Ray Test, you will be given X-Ray images of luggage filled with a variety of objects. Usually, you will be provided two practice sessions before you start the actual test. First, you will be required to memorize the shapes of three to six target items in 30 seconds, this will help you identify the required item on the next screen. Then you will be required to identify a target item, as per the instructions given, within a 15 second time period.

What Type of Images Should You Expect to See?

In an X-Ray portion of the test, you will see a mix of dangerous and mundane objects embedded in X-Ray images. You will encounter threatening items like guns, knives, bombs, IEDs and so on. You will also encounter images with zero harmful items. It is your job to set an alarm if you find a contraband item in an X-Ray image.

How Complex Will the Images Be?

The X-Ray images you see will vary in complexity depending on how the target objects mix or overlap with other objects. There is no rhyme or reason to how complex an image might be. Some images will be more complicated than others. More complex images may require you to rotate items mentally in order to locate their outline or form. Some images may require you to locate various disassembled pieces of the contraband item.

How Many People Pass?

The Object Recognition Test is by far the more challenging portion of the test. Only 30% of test-takers actually pass the test. In rare cases, those who pass the test may be asked to take it again just to make sure you actually passed due to your visual and cognitive skills, rather than sheer luck.

What Are the Testing Circumstances?

The test is given at a specified testing center. Make sure you arrive 30-45 minutes early to fill out any extra forms. The entire test takes a total of 2.5 hours and each section is given under time constraints. Each question in the Object Recognition Test is given under timed conditions. The English portion of the test is all multiple choice questions.

What Are Some of the Items Which Are Banned?

The following is a comprehensive list of items that are banned in Carry-Ons and Checked Luggage.

How Do You Read an X-Ray?

Interpreting an X-Ray can be quite challenging. Understanding the different color combinations and finding harmful items can be trickier than one would expect.

Black and white images are quite sharp. Depending what you are looking for the items can be quite visible. You can easily parse out the gun, bullets and computers.

How Do You Interpret X-Ray Colors?

If the image is not so straight forward you can use color detection. The basics to understanding color principles in X-Rays is knowing that color highlights the difference in density of various materials. When an item is more dense it will be bluer. Conversely, less dense, lighter items will be on the red scale.

Blue/Black

The color blue usually denotes hard materials including; metal, hard plastics, alloys etc. Any wires, batteries, sunglasses, guns, etc. will show up on the blue/ black scale.

Green

Green represents less dense plastics and alloys. The combination of plastic and metal will most likely be some kind of electronic device.

Orange

The orange represents any biological material. This covers natural items and some other materials including; rubber, food, leather, non-plastic explosives, liquids, gels and organic powders (like flour, baking soda, ect.). These colored items are often important to pay attention to because explosives are often partly composed of organic materials like glycerin, potassium nitrate, and TNT. Additionally, drugs such as heroin, cocaine, and cannabis are all classified as organic products. That's why identifying biological materials is extremely important.

Red

Red zone indicates less dense items. This means the machine encountered little to no resistance when scanning the object. This object could be made out of light materials including; fabric, carton, or paper.

How Do You Read the Airport X-Ray Image?

Now that you have a basic understanding of the materials categorized by color, it is important to identify the outline of a target object. Often items might be placed on the conveyor belt at an odd angle, keep this in mind when detecting the objects outline.

Disclaimer
There will be slight differences in color depending on the machine and manufacturer. It is important to understand the basic principles and once you are hired as a TSO officer you will receive ample training on the subject.
