CRT Frequently Asked Questions
What does CRT stand for?
CRT stands for NBRC Certified Respiratory Therapist (CRT). It is administered by NBRC.
Who administers the CRT?
The NBRC Certified Respiratory Therapist (CRT) (CRT) is administered by NBRC. For official information, visit the NBRC website.
How difficult is the NBRC CRT exam?
The NBRC CRT is earned by passing the Therapist Multiple Choice (TMC) exam at the "low cut score." The TMC is considered moderately challenging for recent CoARC-accredited program graduates. First-time pass rates at the low cut score are approximately 75–85%, making CRT the more accessible starting credential compared to RRT.
What are the eligibility requirements for the NBRC CRT?
You must be a graduate of a CoARC-accredited respiratory therapy program. Most programs are at least associate degree level. After passing the TMC at the low cut score, you receive the CRT credential. State licensure is handled separately through each state's respiratory care licensing board.
How long should I study for the NBRC CRT (TMC)?
Most candidates need 2–4 months of focused study using the TMC Review from NBRC, The Respiratory Therapist Exam Guide, and practice exams. Those aiming for RRT should study for the high cut score from the beginning to avoid having to retake the TMC after obtaining CRT.
What career value does the NBRC CRT credential provide?
CRT allows entry-level respiratory therapists to begin working under appropriate supervision in many states. CRTs typically earn $45,000–$65,000. While CRT is a valid starting credential, most employers encourage and often require advancement to RRT for long-term career viability in acute care.
What is the NBRC CRT (TMC) retake policy?
After a failed TMC attempt, a 60-day waiting period applies. A maximum of eight total TMC and CSE attempts combined are allowed within the eligibility window.
How long is the NBRC CRT credential valid?
The NBRC CRT does not have a formal expiration date at the national credential level. State respiratory therapy licenses require annual or biennial renewal with continuing education as required by each state board.
What continuing education is required to maintain a state respiratory therapy license?
CE requirements vary by state, typically ranging from 12–24 hours per renewal cycle. AARC-approved continuing education programs are accepted in most states. Staying current with clinical evidence and AARC practice guidelines is professionally expected.
Should I pursue CRT or aim directly for RRT?
The TMC is taken only once and the score determines which credential you earn. Studying specifically for the high cut score from the start means you can earn RRT immediately upon passing — there is no advantage to planning for CRT first and RRT later as a strategy. All recent graduates should study with the RRT standard in mind; CRT is simply the result if you pass below the high cut score threshold.
