RRT Exam

To be a Registered Respiratory Therapist or RRT means that you have passed two examinations that measure your skills, abilities, and knowledge essential for advanced respiratory therapists. This credential, once earned, is recognized nationally as the stand of excellence for professionals in this field.

The first exam is the Therapist Multiple-Choice Exam or TMC. Before January 2015, it was known as the Therapist Written Registry Exam. This exam evaluates the entry level abilities required of respiratory therapists. If you pass this exam with a high cut score you can move on to the next one, which is the CSE or Clinical Simulation Exam.

  • At least 18 years old and have at least an associate’s degree from an advanced level respiratory therapy education program supported or accredited by CoARC
  • A CRT for at least four years with at least 62 semester hours of college credit from a regionally accredited institution. These 62 hours must include a course in:

    • Microbiology
    • Mathematics
  • A CRT for at least two years and has at least an associate’s degree from an accredited entry-level respiratory care education program

The TMC exam costs $190 for new applicants. You will have three years after you pass the TMC to earn RRT credential. During that time, you must take the CSE. The CSE fee is $200.

When and Where is it Taken?

Once your application has been approved, you will receive an eligibility email. This will contain instructions to schedule your exam. All TMC exams are taken through PSI testing centers.

These can be scheduled Monday to Saturday year-round at one of nearly 300 testing sites country-wide.

You must bring two valid forms of identification with you to sign in. These should include your correct name, signature, and one with a photo.

The exams are delivered via computer. This means any personal items are not needed. This includes calculators, pencils, food and drink, and electronic devices. These will not be permitted in the testing area unless otherwise instructed in your certificate handbook.

What is Covered?

The TMC exam consists of 160 multiple choice questions, which includes 20 unscored pretest questions. You are given a total of three hours to complete it.

  • Patient Data (50 Questions)
    • Evaluate data in the patient record

How is it Scored?

Scores are given to you immediately after you complete the exam at the testing center. You can earn one of two cut scores. The low cut score earns the CRT credential. The high cut score earns the CRT credential and eligibility to take the CSE. If you do not make either cut you must reapply to take it again.

Your official credentials will be mailed to shortly after you have passed your exam, along with instructions as to your next step(s).
