Test Breakdown & Sample Questions
The Legacy Test (aka X-ray)
The legacy version of the test focuses predominantly on X-ray object recognition and English language proficiency, reflecting the day-to-day responsibilities of a TSO. As a prospective TSA officer, your ability to accurately and swiftly identify harmful and harmless objects is paramount. This skill is not only essential for your role but is also a significant part of the TSA Computer-Based Test (CBT), specifically the Screener Object Recognition Test.
This test assesses your ability to interpret X-ray images, a common task for TSA officers. To excel in this test, you’ll need to master several techniques that will aid in your object identification process. These techniques include understanding object colors, recognizing object shapes and sizes, and dealing with overlapping objects.
- Object Colors: In X-ray images, different materials are represented by different colors based on their composition and density. Organic materials, such as food, leather, or explosives, often appear as orange. Metals, which are denser, appear blue or green. Lighter materials like plastics, ceramics, or precious stones can appear in shades of black, gray, or sometimes green. By understanding these color codes, you can quickly identify the material composition of an object and determine if it’s potentially harmful.
- Object Shapes and Sizes: The shape and size of an object can provide crucial clues about its identity. For instance, a knife will have a distinctive shape, regardless of its orientation. Similarly, a gun will have a recognizable outline, whether it’s viewed from the side, top, or any angle. Familiarize yourself with the shapes and sizes of common prohibited items to enhance your object recognition skills. Remember, harmful objects can come in all sizes, so don’t dismiss something just because it’s small.
- Overlapping Objects: This is one of the trickier aspects of X-ray image interpretation. When objects overlap, their shapes and colors can blend, making identification more challenging. However, you can use the color and shape techniques mentioned above to piece together what each object might be. Look for distinctive features or parts of objects that aren’t obscured. Practice is key here; the more images you review, the better you’ll become at identifying objects, even when they overlap.
Key Techniques for Object Identification in the TSA CBT Test
| Technique | Description | Application |
|---|---|---|
| Object Colors | Different materials are represented by different colors in X-ray images based on their composition and density. | Understand the color codes to quickly identify the material composition of an object and determine if it’s potentially harmful. |
| Object Shapes and Sizes | The shape and size of an object can provide crucial clues about its identity. | Familiarize yourself with the shapes and sizes of common prohibited items to enhance your object recognition skills. |
| Overlapping Objects | When objects overlap, their shapes and colors can blend, making identification more challenging. | Look for distinctive features or parts of objects that aren’t obscured. The more images you review, the better you’ll become at identifying objects, even when they overlap. |

- No
There is an IED within the baggage.
In this X-ray scan, the IED is identifiable by its combination of dense metallic components, such as wiring and a detonator, and the orange-colored explosive material. The arrangement of these elements, including a possible battery or power source, aligns with typical IED structures. The distinct orange signature of the explosive highlights its presence, differentiating it from harmless items like mobile phones, which lack the same color and configuration.
Cameras
The body of a camera is typically made from high-density plastic or metal alloys, which show up as dark green or even blue on an X-ray scan. The camera’s lens, being extremely dense, may appear almost black.
X-Ray Recognition Question 7 of 10
Is there a camera within the baggage?
- Yes
- No
There is a camera within the baggage.
There are actually two cameras. These were pulled out of the baggage for demonstration purposes.
The other metallic (blue) devices that can be seen are a few keys, two AA batteries, and a few pullers of zippers.
X-Ray Recognition Question 8 of 10
Is there a camera within the baggage?
- Yes
- No
There isn’t a camera within the baggage.
While it seems similar to a camera, the blue object is in fact the motor of a vacuum cleaner. While the darker part may seem like the camera’s lens, the body of the camera cannot be found. The green-blue round object is the vacuum cleaner’s power cord.
Shoes
Shoes are made of organic fabrics or very light plastic materials. They usually have an orange shade, which means that it might be quite difficult to recognize them among other objects. Try to locate metallic plates which are often inside the sole of the shoe.
X-Ray Recognition Question 9 of 10
Is there a pair of shoes within the baggage?
- Yes
- No
There are no shoes in the baggage.
There are several objects made of organic materials within the baggage (orange shade) but these are clothes rather than shoes. The main object in the center is a metal bottle with a screw cap (blue) filled with some fluid (hence the orange shade). At the bottom right there is also a wallet with a few coins.
X-Ray Recognition Question 10 of 10
Is there a pair of shoes within the baggage?
- Yes
- No
There are shoes in the baggage.
There are actually two pairs of high-heeled shoes in the bag. These can be identified by the metal plates implanted inside the heels and all the way through the soles.
2.2. Writing Skills
Writing Skills Question 1 of 2
Select the one word or phrase that needs to be used in place of the underlined text to make the sentence correct, or indicate that the underlined text is not in error.
At Fire Island, a popular tourist spot east of the city, the remains of what might have been the shipping vessel were uncovered.
- NO ERROR
- has been
- had been
- having been
The correct answer is A.
Explanation: The word “might” is an auxiliary verb. Therefore, because of the addition of “might,” the only possible answer is “have been.”
Writing Skills Question 2 of 2
Put the following sentences into the correct order to create a logical and flowing paragraph.
Sentence 1. With an ever-increasing population, clean water is becoming even more essential in developing African countries and it is estimated that investments of over $800 billion will be needed in the next few years.
Sentence 2. Drink 2025 is an initiative which aims to unite 7 drought-affected African nations in order to conserve water supplies and provide citizens with an uninterrupted supply of drinkable water.
Sentence 3. The initiative will bring together water conservation experts from around the globe, government agencies, charities, multilateral organizations, and private companies in order to raise the needed capital.
Sentence 4. The investment will ensure Africa remains healthy and disease free for many years to come.
- 1, 2, 3, 4
- 1, 3, 4, 2
- 2, 4, 1, 3
- 4, 3, 1, 2
The correct answer is A.
Explanation:
The logical flow of the paragraph is as follows.
Introduce the problem > Introduce the solution > Talk about the aims of the solution > Conclusion
Note the vocabulary connections in each sentence too.
“Developing African countries” in the 1st paragraph pairs with “7 drought-affected African nations” in the 2nd.
“Drink 2025” in the 2nd pairs with “the initiative” in the 3rd.
“Needed capital” in the 3rd pairs with “investment” in the 4th.
When tackling this type of question, you must take these vocabulary connections into account.

You have a great program here. It covers everything you could possibly need to get thru the test and more. It was worth every penny I spent. Iprep should not change anything about this program., I take my test in a week and I know I will pass on this try. Thank you so much for putting out such a great program. Roberta Fraine

I will be taking the TSA test and I found that iPREP was incredible helpful. The practice mock test where very similar to what I can except for the actual exam. I really liked how they actually showed the 2D and 3D images and how they came together. I'd highly recommend IPrep to understanding the test format.

This course is designed by professionals for aspiring professionals. The exercises are excellent. Everything is explained very well. I'm very pleased with the large number of x-ray images. Everything is explained perfectly. This is exactly what I was looking for. Many thanks to the entire team.

The 2d to 3d section looks nothing like the real test. However, I did pass the test and received a TJO.

Tremendous help!! Just being familiar with looking at the images and shapes was vital in my experience. The free practice questions were a wake up and hinted to me this would be useful. The 3-D/2-D questions felt routine after a couple days of practice and sure enough, I got quick confirmation I had passed and received a "tentative job offer" (step 1 of many, but this is the start!). I don't know if that means I was in the top bracket, but I felt quite confident about my answers and time. Yes, highly recommended and it was the most affordable prep option!!

Well I just took the real test for the TSO. The 2-d to 3-d was very different from the I-prep practice tests. I would not recommend relying on iprep alone to study for your exam

I looked for a long time for material that would allow me to prepare for this Test. I tried some, but this one beats them all! I feel like I am learning, retaining information and generalizing skills! Very happy about my purchase.

Amazing content. Really thorough and comprehensive. I like the way it was building up the content starting from what the test used to be and moving progressively towards the new additions.
