No.
👉 You cannot become a Registered Respiratory Therapist (RRT) without passing the high cut score on the Therapist Multiple-Choice (TMC) Exam.
Many students misunderstand this process because the TMC exam has two passing thresholds:
| TMC Result | Outcome |
|---|---|
| Below low cut score | No credential earned |
| At or above low cut score but below high cut score | Earn CRT credential |
| At or above high cut score | Eligible for the CSE exam and RRT pathway |
If you do not achieve the high cut score, you cannot move forward to the Clinical Simulation Examination (CSE), which is required to earn the RRT credential.
Why Does the TMC Exam Have Two Passing Scores?
The National Board for Respiratory Care (NBRC) uses the TMC exam to evaluate different competency levels.
The exam identifies:
CRT-Level Competency
Candidates who demonstrate entry-level respiratory therapy knowledge may earn the:
👉 Certified Respiratory Therapist (CRT)
credential.
RRT-Level Competency
Candidates who demonstrate stronger clinical reasoning and decision-making skills become eligible for:
👉 The Clinical Simulation Examination (CSE)
which is the final step toward becoming an RRT.
What Happens If You Pass the Low Cut Score?
This is where many students become confused.
You may technically “pass” the TMC exam and still not qualify for the RRT pathway.
In that situation:
- You earn CRT status
- You do not qualify for the CSE
- You cannot become an RRT yet
This is one of the most common outcomes among candidates who narrowly miss the high cut score.
Is CRT Still a Valid Credential?
Yes.
CRT is a legitimate respiratory therapy credential.
However, the profession has increasingly moved toward the RRT credential as the preferred standard.
Many employers now view RRT as the expected credential for respiratory therapists.
Why Most Students Aim for the High Cut Score
The goal for most candidates is not simply passing.
The goal is becoming eligible for the CSE and ultimately earning the RRT credential.
Benefits of achieving RRT status often include:
- Greater employment opportunities
- More competitive job applications
- Access to advanced clinical roles
- Improved long-term career flexibility
Why Students Miss the High Cut Score
Many candidates who earn CRT but miss RRT eligibility make similar mistakes.
Focusing on Memorization
The TMC exam tests much more than factual recall.
Candidates must apply knowledge to patient scenarios and make clinical decisions.
Weak Clinical Reasoning
Many questions require you to determine:
- The best next action
- Appropriate therapy adjustments
- Prioritization of patient care
Candidates who rely on memorization alone often struggle here.
Poor Time Management
Some students understand the material but:
- Spend too long on difficult questions
- Rush later sections
- Leave questions unanswered
This can be enough to miss the high cut score.
Weak High-Yield Topics
Common problem areas include:
- Mechanical ventilation
- Arterial blood gases (ABGs)
- Oxygen therapy
- Pulmonary function concepts
- Patient assessment
How Close Are Most Candidates?
Many students who miss the high cut score are surprisingly close.
A small number of questions can determine whether you:
- Earn CRT only
- Become eligible for the CSE
This is why strategic preparation matters so much.
Can You Retake the TMC to Reach the High Cut Score?
Yes.
There is no lifetime limit on TMC attempts.
Many candidates:
- Earn CRT
- Continue studying
- Retake the TMC
- Achieve the high cut score
- Move on to the CSE
Should You Retake Immediately?
Not always.
Before scheduling another attempt, ask yourself:
Did I run out of time?
Did I understand why I missed questions?
Was my preparation mostly reading rather than application?
Are my current practice scores above the high cut score?
If the answer to these questions is no, additional preparation is usually the better investment.
How to Improve Your Chances of Reaching the High Cut Score
Focus on Clinical Decision-Making
The highest-scoring candidates think like respiratory therapists, not test takers.
Practice Scenario-Based Questions
These most closely resemble the reasoning required on the actual exam.
Review Every Mistake
Don’t just learn the correct answer.
Learn:
- Why it is correct
- Why the other options are wrong
Take Full-Length Timed Exams
You need to develop:
- Endurance
- Accuracy
- Timing
before test day.
How Do You Know You’re Ready for the High Cut Score?
You are usually ready when:
- You consistently score above the high cut range on practice exams
- You finish practice exams on time
- You understand clinical reasoning patterns
- You can explain why answers are correct
The Biggest Mistake Candidates Make
Many students aim to “pass.”
The problem is:
👉 Passing and becoming an RRT are not the same thing.
The candidates who achieve RRT status prepare specifically for the high cut score from the beginning.
Check Your Current TMC Level
Before scheduling your exam or retake, find out where you stand.
