Respiratory Therapist Multiple-Choice (TMC) Exam

The TMC exam is administered by The National Board for Respiratory Care (NBRC) to test applicants’ knowledge of the field and determine who should receive NBRC credentialing. Performance on the test helps determine credentialing as either a Certified Respiratory Therapist (CRT) or Registered Respiratory Therapist (RRT).

What Is The Difference Between An RRT And A CRT?

The TMC exam has two cut scores — selected points on the score scale of the test. With a low cut score, applicants receive credentials as a CRT. With a high cut score, they receive the CRT credential and become eligible for the Clinical Simulation Examination (CSE). A passing score on the CSE is a requirement for becoming an RRT.

In essence, the CRT credential is an entry credential and the RRT is an advanced credential. Both are used as the basis for state licensure in the 49 states that regulate respiratory care practices.

How Is The TMC Exam Constructed And Administered?

The TMC exam consists of 160 multiple-choice questions, with 140 scored items and 20 pretest items. Applicants must be at least 18 years old and a graduate with an associate degree from a respiratory therapy education program or a practicing CRT for several years before applying for RRT credentials.

The exam is given at designated assessment centers around the country. The examination fee is $190 for new applicants and $150 for repeat applicants. Applicants are given three hours to complete the test.

How Is The TMC Exam Content Divided?

The TMC exam is broken down into three main sections (Patient Data Evaluation And Recommendations, Troubleshooting And Quality Control Of Equipment, And Infection Control and Initiation And Modification Of Interventions), each with several subsections. There is some content overlap between these, as certain areas of focus can apply to numerous sections.
