TSA X-Ray Test Practice (2025 Guide)
The TSA X-Ray Test, also called the Image Interpretation Test, is one of the most challenging parts of the TSA CBT exam. It measures how well you can identify prohibited items in luggage scans — a skill that’s critical for Transportation Security Officers. This guide explains how the X-ray test works, what types of images you’ll see, and how to prepare effectively using real practice methods.

What Is the TSA X-Ray Test?
The TSA X-Ray Test is a section of the TSA Computer-Based Test (CBT). It presents you with X-ray images of luggage, and your job is to quickly identify threat items like guns, knives, or explosives.
It evaluates your:
- Visual recognition skills
- Spatial reasoning
- Ability to detect threats under pressure
The images are often rotated, overlapping, or shown in unusual color filters, which makes object identification more difficult.
TSA X-Ray Image Colors Explained
X-ray machines used in TSA testing display objects in three main colors:
- Orange – Organic materials (food, clothing, paper, liquids)
- Blue/Black – Metal or dense materials (weapons, tools, electronics)
- Green – Mixed or plastic materials (composite items, batteries, bottles)
Learning what each color means is key to quickly spotting potential threats during the test.
What Kind of Items Appear on the TSA X-Ray Test?
You may be asked to identify any of the following categories:
- Guns or firearm parts
- Knives or sharp objects
- Explosives or detonators
- Wires and batteries
- Liquids or gels
Sometimes, these items are partially hidden under other objects or rotated at odd angles.
Is the TSA X-Ray Test Hard?
Yes, many candidates find it difficult at first because it requires strong spatial awareness and pattern recognition. However, with consistent practice, you can learn to recognize objects more quickly.
Reddit users often describe the X-ray test as the toughest part of the TSA CBT:
“The X-ray section was brutal at first, but after doing a few practice rounds, it got easier.”
“I learned to look for handles, triggers, and blade shapes even when they’re turned sideways.”
TSA X-Ray Test Practice Strategy
Here’s how to effectively prepare for the TSA X-ray section:
1. Study X-Ray Object Examples
Review real or simulated X-ray images online. Focus on identifying the outlines of common threat items like guns and knives.
Try to visualize how they’d appear from different angles.
2. Learn Object Layering
Practice looking through overlapping shapes. The test is designed to confuse you with cluttered bags, so focus on texture and density patterns instead of just outlines.
3. Time Your Practice Sessions
The real test is timed, and you’ll have only a few seconds per image. Use online simulators or flashcards to train your reaction time.
4. Use Free TSA CBT Practice Tools

How Many Questions Are on the TSA X-Ray Test?
The number of questions varies, but typically there are around 100–120 X-ray images. Each image is shown for a limited time (around 10–15 seconds). You must choose whether the bag contains a threat item before moving to the next question.
You can’t skip or return to previous questions.
How to Identify Threat Items Quickly
Here are visual cues that can help you recognize items faster:
- Guns: Look for rectangular shapes with cylindrical barrels.
- Knives: Thin, sharp edges or blade-like shapes near handles.
- Explosives: Unusual densities, wires, or connected shapes.
- Liquids: Rounded or bottle-shaped containers.
Remember, practice helps your brain learn to identify these shapes automatically.
Common Mistakes to Avoid
- Rushing without scanning the full image – You might miss small items like blades or wires.
- Focusing only on one color – Pay attention to density and shape, not color alone.
- Overthinking each image – Trust your instincts once you’ve practiced enough.
Can You Practice the TSA X-Ray Test Online?
Yes, you can practice online using free TSA CBT simulators and image recognition exercises. These tools mimic the timing and visual complexity of the real test. While TSA doesn’t publish official practice materials, third-party training sites and YouTube tutorials can be helpful.

How to Improve Your X-Ray Object Recognition Skills
- Daily Image Flashcards: Spend 10–15 minutes reviewing luggage images.
- Focus on Shape Patterns: Recognize key shapes (e.g., barrel, blade, wire).
- Simulate Pressure: Use timers to recreate real test stress.
- Review Mistakes: Learn what you missed and why.
What Happens If You Fail the X-Ray Test?
If you don’t pass the X-ray portion, you’ll receive a Did Not Qualify email. You can reapply for a TSA position after six months and retake the entire CBT.
Failing once isn’t the end — most successful applicants passed on their second or third attempt after better preparation.
