The National Board for Respiratory Care (NBRC) offers certification and registration to graduates of programs accredited by CAAHEP or the Committee on Accreditation for Respiratory Care (CoARC).
CRT Examination
Two credentials are awarded to respiratory therapists who satisfy the requirements: Registered Respiratory Therapist (RRT) and Certified Respiratory Therapist (CRT).
Graduates from accredited entry-level or advanced-level programs in respiratory therapy may take the CRT examination. CRTs who were graduated from advanced-level programs and who meet additional experience requirements can take two separate examinations leading to the award of the RRT credential.
All States (except Alaska and Hawaii), the District of Columbia, and Puerto Rico require respiratory therapists to obtain a license. Passing the CRT exam qualifies respiratory therapists for State licenses. Also, most employers require respiratory therapists to maintain a cardiopulmonary resuscitation (CPR) certification. Supervisory positions and intensive-care specialties usually require the RRT or at least RRT eligibility.
Respiratory care involves basic mathematical problem solving and an understanding of chemical and physical principles. For example, respiratory care workers must be able to compute dosages of medication and calculate gas concentrations.
