The TSA color vision test is part of the medical evaluation used in Transportation Security Officer (TSO) hiring, not a separate computer-based practice exam like the CBT X-ray section.
Official TSA TSO hiring materials state that the medical evaluation can include color vision testing, distance vision testing, a hearing exam, a physical exam, and bloodwork. Those checks support safe performance of screening duties under TSA medical guidelines.
Medical vision check vs CBT image practice
Candidates often confuse two different “visual” demands:
| Stage | What it evaluates | Typical timing |
|---|---|---|
| Computer-based assessment | Image-interpretation aptitude and related screening skills used in early hiring | After minimum qualifications, when invited |
| Medical color/distance vision | Whether vision meets medical requirements for the TSO role | During the medical evaluation after later hiring stages |
Improving X-ray object recognition through practice does not replace medical color-vision screening. Likewise, passing medical vision checks does not prepare you for CBT image rules. Use the TSA X-ray Test guide and TSA CBT guide for assessment practice, and the TSA Medical Evaluation page for the medical stage.
What official materials ask candidates to do
TSA publishes a medical checklist and TSO Medical Guidelines for applicants. Those resources explain completing the SOMQ, scheduling through the Examinee Access System flow described in the checklist, and bringing documentation to the appointment. Review:
If you have a known vision condition, discuss the guidelines with your treating clinician and bring supporting documentation when the medical process requests it. This site does not interpret medical guidelines for individual cases.
Preparation that is realistic
Useful steps:
- read the medical checklist before your appointment window;
- bring required glasses or corrective lenses instructions if applicable to your appointment guidance;
- keep medication and diagnosis lists ready for the SOMQ;
- schedule enough time so paperwork is complete before the exam date.
Avoid unofficial “color plate practice” marketed as a guaranteed TSA pass. Medical adjudication follows TSA guidelines and individualized assessment, not commercial color-quiz scores.
