RRT vs CRT: Which Respiratory Therapy Credential Should You Pursue?

Comparing Entry-Level and Advanced Respiratory Therapy Credentials

Overview

The CRT (Certified Respiratory Therapist) and RRT (Registered Respiratory Therapist) are both awarded by the NBRC based on the same TMC Examination — but at different cut scores. The RRT requires passing an additional exam (CSE) and represents the highest level of respiratory therapy credentialing.

Career Impact

The RRT credential opens doors to leadership positions, specialty roles, and higher salaries. Many hospitals and health systems require or prefer RRT for advanced roles. The RRT is also a prerequisite for specialty credentials like ACCS, NPS, and SDS.
