Introduction
The American Association for Respiratory Care (AARC) supports the Registered Respiratory Therapist (RRT) credential as the minimum standard for entry into the profession. As respiratory care has evolved, an increasing number of states have adopted laws or regulations requiring the RRT credential (or equivalent registry-level qualification) for initial licensure.
As of July 2026, 9 states have enacted RRT entry-to-licensure requirements, with Missouri’s law taking effect January 1, 2027. These states have demonstrated that successful implementation is achievable through careful planning, collaboration, and appropriate grandfather provisions.
View the current list of states requiring the RRT credential for initial licensure.
This guidance is intended to help state respiratory care societies evaluate, develop, and implement legislation or regulations establishing the RRT credential as the minimum qualification for new license applicants.
Why Move to RRT Entry to Licensure?
All graduates of Commission on Accreditation for Respiratory Care (CoARC)-accredited respiratory therapy programs are educated to meet eligibility requirements for the National Board for Respiratory Care (NBRC) registry-level examination.
Requiring the RRT credential for initial licensure:
- Promotes a consistent national standard for entry into practice.
- Reflects the increasing complexity of respiratory care.
- Aligns licensure with employer expectations in many states.
- Supports professional recognition and workforce mobility.
- Reinforces the respiratory therapist’s role as an essential member of the healthcare team.
States should carefully evaluate workforce implications and ensure that implementation does not unintentionally reduce patient access to care.
