How Many Times Can You Take the TMC Exam? (Retake Rules Explained)

crt vs rrt

In this article...

The National Board for Respiratory Care (NBRC) does not place a lifetime limit on the number of times you can take the TMC exam.

However, there are important retake rules, waiting periods, fees, and eligibility requirements that every candidate should understand before scheduling another attempt.

The bigger question is usually not:

👉 “Can I retake the exam?”

It’s:

👉 “Should I retake the exam right away?”


Understanding the TMC Retake Policy

If you do not achieve the score you need on the TMC exam, you can retake it.

Most candidates fall into one of three categories:

ResultOutcome
Below low cut scoreNo credential earned
Above low cut score but below high cut scoreEarn CRT credential
Above high cut scoreEligible for the CSE exam and RRT pathway

The Most Common Retake Scenario

Many candidates do not completely fail the exam.

Instead, they:

  • earn CRT status
  • miss the high cut score
  • need another attempt to qualify for the CSE

This situation is much more common than students realize.


Should You Retake Immediately?

Not necessarily.

One of the biggest mistakes candidates make is scheduling another exam before understanding why they missed their target score.

For example:

Bad Strategy

  • Fail on Friday
  • Schedule another attempt immediately
  • Continue using the same study methods

Result:

👉 Often the same outcome.


Better Strategy

First identify:

  • weak content areas
  • timing problems
  • question interpretation issues
  • clinical reasoning mistakes

Then create a focused improvement plan.


Why Most Students Need a Retake

After reviewing hundreds of student experiences, the same patterns appear repeatedly.


Poor Time Management

Students know the material but:

  • spend too long on difficult questions
  • rush later sections
  • leave questions unanswered

Focusing on Memorization

The TMC is not primarily a memorization exam.

It tests:

  • clinical decision-making
  • patient assessment
  • treatment priorities

Weak High-Yield Areas

Many retakes involve weaknesses in:

  • mechanical ventilation
  • arterial blood gases (ABGs)
  • oxygen therapy
  • patient assessment

When Are You Actually Ready to Retake?

Do not use the calendar as your guide.

Use performance.

You are usually ready when:

You Consistently Score Above Your Goal

If your goal is the high cut score:

👉 Your practice scores should consistently exceed it.


You Can Finish on Time

Many candidates improve content knowledge but still struggle with pacing.


You Understand Why Answers Are Correct

Not just what the answer is.

The strongest candidates understand:

  • why the correct option is correct
  • why the other choices are wrong

What If You Earned CRT But Want RRT?

This is one of the most common situations.

You may have:

  • technically passed the TMC
  • earned CRT
  • missed the high cut score

In that case, many candidates choose to:

  • continue studying
  • retake the TMC
  • aim for CSE eligibility

Because in many healthcare settings, RRT is the preferred credential.


How Long Should You Wait Before Retaking?

There is no perfect answer.

It depends on:

If You Barely Missed

For example:

  • missed by only a few points
  • identified specific weaknesses

You may need only a few weeks of focused preparation.


If You Missed by a Large Margin

You likely need:

  • a structured study plan
  • content review
  • multiple practice exams

Rushing back into testing usually wastes time and money.


Retake Cost Considerations

Every additional attempt means:

  • exam registration fees
  • preparation costs
  • time investment

This is why improving your study strategy before retesting is critical.


Questions to Ask Before Scheduling Another Attempt

Before you pay for another exam, ask:

Did I run out of time?

Which content areas hurt my score?

Was my preparation mostly passive reading?

Am I consistently scoring above my target score now?

If you cannot answer these questions, you’re probably not ready yet.


What Top-Scoring Candidates Do Differently

Candidates who reach the high cut score typically:

  • practice under timed conditions
  • focus on clinical reasoning
  • review mistakes carefully
  • use full-length simulations

They do not simply reread textbooks.


Check Your Current TMC Level

Before scheduling another attempt, see where you stand.


Final Insight

The NBRC allows you to retake the TMC exam.

The challenge is not access.

The challenge is making sure your next attempt is meaningfully better than your last one.

Most candidates who improve significantly do not study harder.

👉 They study more strategically.
