The TSA medical evaluation is a post-offer screening step for many Transportation Security Officer (TSO) candidates. Official TSA careers materials list medical evaluation and federal drug screening among the requirements for TSO hiring, typically after computer-based testing and airport assessment stages are successfully completed.

This page explains what the medical stage is for, what official TSA resources say candidates should prepare, and how it differs from the CBT or interview. It does not provide medical advice and does not decide whether any individual condition qualifies or disqualifies a candidate.

Where the medical evaluation sits in the hiring process

According to TSA’s TSO careers page, the hiring process can include:

  1. finding and applying to a Job Opportunity Announcement on USAJOBS;
  2. computer-based testing for image-interpretation aptitude when invited;
  3. a tentative job offer;
  4. airport assessment and structured interview;
  5. medical evaluation and federal drug screening;
  6. background investigation and later onboarding steps.

Exact order and timing can vary by airport and hiring need. Use your candidate portal messages and the live vacancy for your schedule.

For the broader sequence, see the TSA Hiring Process guide. For earlier assessment prep, start with the TSA Practice Test hub or TSA CBT guide.

What official TSA materials say the evaluation includes

TSA’s public TSO hiring summary states that the medical evaluation can include a physical exam, bloodwork, color vision testing, distance vision testing, and a hearing exam. Federal drug screening is listed separately and is also required.

TSA also publishes candidate-facing medical resources, including:

Those documents explain how applicants complete the Transportation Security Officer Medical Questionnaire (SOMQ), provide availability for scheduling, and bring required documentation to the appointment. They also describe appeal options if TSA determines an applicant is medically disqualified after individualized assessment.

Practical preparation that actually helps

Useful preparation is administrative and logistical, not quiz-style cramming:

  • complete the SOMQ carefully and gather medication lists, diagnoses, and supporting documentation before the appointment window;
  • bring the completed forms and documentation requested in the medical checklist;
  • follow instructions about the medical kit and appointment logistics in the official checklist;
  • review the TSO Medical Guidelines with your treating clinician if you have conditions you expect to discuss;
  • keep contact details for the medical-scheduling and hotline addresses listed on the official checklist if you need scheduling help.

Do not invent “practice tests” for bloodwork or hearing. The high-value work is accurate paperwork, clear documentation, and showing up prepared.

Color and distance vision checks are part of the medical evaluation described by TSA for TSO candidates. If your question is specifically about color-vision screening, use the dedicated TSA Color Vision Test page. That page focuses on vision requirements inside the medical stage rather than CBT image drills.

How this differs from CBT practice

Computer-based testing measures job-related cognitive and visual-screening skills used earlier in hiring. The medical evaluation assesses whether you can safely and effectively perform TSO functions under TSA medical guidelines. Strong CBT practice does not substitute for medical clearance, and medical clearance does not remove the need for assessment preparation earlier in the process.
