TSA CBT Test & TSA Test Prep Guide (2025 Edition)
If you’re applying for a Transportation Security Officer (TSO) position, the TSA CBT Test is one of the first challenges you’ll face. It’s a crucial step in the hiring process that determines if you move forward or not. This guide explains everything you need to know about the TSA CBT — from test format and scoring to effective study methods and free practice resources.
What Is the TSA CBT Test?
The TSA CBT (Computer-Based Test) is an online exam used by the Transportation Security Administration to evaluate candidates applying for airport security jobs. It’s often referred to as the TSA Computer-Based Test or TSO Test.
The exam is designed to measure two main skill areas:
- X-Ray Object Recognition (Image Interpretation Test)
- English Proficiency (Writing and Reading Comprehension)
Passing this test is mandatory to continue in the TSA hiring process.
TSA CBT Test Format Overview
The TSA CBT consists of two timed sections:
1. X-Ray Test
In this section, you’ll see X-ray images of luggage and must identify prohibited items such as guns, knives, or explosives. You’ll need to recognize shapes, sizes, and object placements under various colors and filters.
2. English Test
This section evaluates grammar, vocabulary, reading comprehension, and writing clarity. It measures how well you can understand written instructions and communicate effectively in English — essential for daily TSA operations.
How Long Is the TSA CBT Test?
The test typically takes around 2.5 hours to complete. Each section is timed separately, and you can’t pause or return once a section ends. Make sure to take the test in a quiet environment with a stable internet connection.
How Is the TSA CBT Test Scored?
TSA uses a pass/fail scoring system, but candidates aren’t told their exact scores. You’ll only receive an email stating whether you passed or did not qualify.
However, performance on the CBT strongly influences whether you’ll get invited for the next step: the Airport Assessment.

- Job Offer and Training

Is the TSA CBT Test Hard?
Many candidates describe the X-Ray section as challenging, especially if it’s their first time identifying 3D shapes in X-ray filters. The English section is generally easier, but time pressure can make both sections stressful.
Common Reddit user advice:
“The hardest part was the X-ray test. My tip — practice identifying knives and guns from odd angles.”
“Don’t rush. You can’t go back once you click next, so stay focused.”
