How Hard Is the RRT Exam?
Pass Rates, Difficulty Factors, and What to Expect
Difficulty Level: Challenging
The RRT credential requires passing TWO exams — the TMC and the CSE — making it more demanding than most single-exam certifications. The CSE in particular tests advanced clinical judgment in simulated patient scenarios.
Why It’s Challenging
- •Two-exam pathway: Must pass TMC at high cut score, then pass CSE
- •Clinical simulation: CSE tests real-time clinical decision-making, not just knowledge
- •Broad content: Covers all aspects of respiratory therapy (adult, pediatric, neonatal, diagnostics)
- •Time pressure: CSE requires managing 22 clinical scenarios in 4 hours
- •High cut score: TMC requires achieving the higher of two cut scores for RRT eligibility
What Makes It Manageable
- •Both exams are multiple-choice or structured simulation (not essay)
- •Free practice exams available from NBRC for both TMC and CSE
- •Well-defined content outlines available
- •Most candidates have completed an accredited RT program, providing foundational knowledge
Pass Rate
NBRC does not publicly release specific pass rates for the TMC or CSE. However, the RRT credential is designed to be achievable for graduates of accredited respiratory therapy programs who prepare adequately.
Common Challenges
- •Mechanical ventilation modes and settings
- •Neonatal/pediatric respiratory care
- •ABG interpretation and clinical application
- •Pharmacology (drug actions, side effects, interactions)
- •Clinical simulation decision-making under time pressure
Tips for Success
- Take the TMC first and pass at the high cut score before starting CSE prep
- Use NBRC free practice exams extensively — they mirror the actual exam format
- Study the Detailed Content Outline to allocate time proportionally
- Focus on clinical application, not just memorization of facts
- For the CSE, practice thinking through clinical scenarios step by step
