NBRC Exam Retake Policy: Attempts, Waiting Periods, and a Better Next Plan
How the NBRC retake waiting period works, when you can reapply, whether TMC and CSE attempts carry into the RT Exam, and how to prepare for another attempt.
Short answer
NBRC allows three initial RT Examination attempts before requiring a minimum of 120 days between subsequent attempts. The Candidate Handbook separately says online reapplication becomes available two business days after an examination; that processing interval does not replace a required 120-day wait. Prior TMC and CSE attempts do not count toward RT attempts, and an existing CRT is retained if a later RT score falls below the low cut.
How many attempts can I make before a waiting period?
NBRC permits three initial RT Examination attempts before a minimum 120-day wait applies between subsequent attempts. Its Candidate Handbook separately makes online reapplication available two business days after an examination, so having no initial minimum retest wait does not mean you can immediately sit another exam.
The RT retake policy and the legacy TMC policy use the same three-attempt starting point, as checked November 3, 2026. Keep a separate record for the examination you are actually taking:
| Your next RT attempt | Minimum waiting-period rule |
|---|---|
| Second attempt | The 120-day rule has not started; reapplication and appointment requirements still apply. |
| Third attempt | The 120-day rule has not started; reapplication and appointment requirements still apply. |
| Fourth attempt | At least 120 days after the third attempt. |
| Each attempt after the fourth | At least 120 days after the preceding attempt. |
Three attempts are the point at which the longer wait starts, not a three-attempt lifetime limit. The waiting rule describes subsequent attempts; it does not promise continued eligibility under every possible circumstance or preserve an examination after its retirement.
For a date example, suppose your third RT attempt is February 1, 2027. Adding 120 days reaches June 1, 2027. That is an editorial calendar calculation, not a booked appointment or an NBRC eligibility decision. Confirm your permitted retest date with NBRC before making travel plans or paying for a date you have assumed is valid.
When can I reapply after an unsuccessful attempt?
The handbook says online reapplication becomes available two business days after the examination. Treat that as a separate step from permission to test again. An application becoming accessible does not remove a waiting period, and neither event guarantees a seat.
Use this sequence:
- Identify the exam and attempt number. Record whether the result is from TMC or RT, the test date, and which attempt it was for that examination.
- Check the applicable waiting period. If your next RT sitting is attempt four or later, use the 120-day rule and confirm the allowed date.
- Reapply when the online process is available. Review the current fee and eligibility information before paying.
- Read the authorization you receive. The handbook normally allows 90 calendar days after an accepted application, but your assigned period is what you should use.
- Book within both constraints. The appointment must respect any retake wait and the authorization dates. If those appear incompatible, ask NBRC before proceeding.
These application rules were checked November 3, 2026. Do not assume an early payment will reserve a later seat or extend your authorization. In particular, a 120-day waiting period and a normal 90-day application period are different clocks, not interchangeable planning windows.
Use the interval to identify the work your next attempt needs. For topic-focused practice, full NBRC RT Exam (TMC) prep is planned for launch with 1,100 questions. Base your immediate schedule on resources already available to you.
Do TMC or CSE attempts count against the RT Exam?
No. NBRC expressly says prior TMC and CSE attempts do not count toward RT Examination attempts. If you previously took the TMC several times and then enter the RT route, those sittings do not make your first RT examination a fourth RT attempt.
That reset concerns the attempt count. You still need to meet RT admission requirements and complete the application process. Do not treat an old examination authorization or an unfinished legacy credential route as automatic admission to the replacement exam.
The first RT administration is January 4, 2027, according to NBRC, checked November 3, 2026. A candidate moving from TMC to RT should also change the preparation target. Our guide to the TMC content areas and the RT outline that replaces them explains the relevant format and content differences.
If you are still trying to book a legacy TMC retake near the transition, confirm the available route and deadlines directly with NBRC. A general retake policy does not establish that a particular examination remains available on your preferred date.
Will another attempt affect the CRT I already hold?
NBRC says an existing CRT is retained if a later RT score falls below the low cut. Its legacy TMC FAQ also preserves an existing CRT after a lower retake result. This answers the specific concern that another attempt could erase a CRT already earned.
First identify what you did and did not achieve on the result. Earning a CRT while falling short of your RRT goal is different from scoring below the CRT standard. The guide to NBRC low and high cut scores and credential outcomes explains that distinction without requiring you to guess from an unofficial percentage.
For your own planning note, write down the credential you already hold, the examination you intend to take next, and the outcome you are pursuing. If your record involves an older admission route or inactive eligibility, ask NBRC to confirm your status before another payment.
How should I use my result to plan the next attempt?
Start with your official result, then use new practice work to identify specific weaknesses. Do not assume you can reconstruct exactly which examination questions you missed. The following worksheet is an editorial study method, not an NBRC remediation requirement or a prediction of your next score.
| What you notice during fresh practice | What to change before retesting |
|---|---|
| You cannot explain a term or principle | Return to that topic in your course materials, then explain it without looking. |
| You know the facts but miss what the question asks | State the requested task in your own words before comparing options. |
| You choose an answer without using relevant case information | List the information that supports your choice and what would make another choice more suitable. |
| You repeatedly lose time on unfamiliar material | Review the topic, then repeat timed mixed practice using new questions. |
| You remember an answer but cannot justify it | Use a different question on the same topic and explain your reasoning. |
Keep the log small enough to use: topic, reason for the error, next study action, and the result of a later check. Repeatedly answering a familiar item correctly does not show that you can handle a new version of the task.
For review organized around the new examination, full NBRC RT Exam (TMC) prep planned for launch covers four outline areas, including Depth of Clinical Judgment. Use the outline to connect a weak topic to a specific learning task rather than restarting every subject equally.
Try the 20 free NBRC practice questions as a small source of fresh work, then use the free NBRC study plan to give those tasks space in your calendar. Neither a small practice set nor a third-party practice score establishes your probability of passing.
What should I verify before paying again?
Check the current repeat fee for the examination you are booking. NBRC lists $300 for a repeat RT examination and $150 for a repeat legacy TMC examination, checked November 3, 2026. Verify the charge and the available examination before a future payment; do not carry the TMC price into an RT budget.
The handbook says fees are not refundable or transferable after eligibility determination. A missed appointment or an expired eligibility period also forfeits the fee. Read the instructions accompanying your authorization and confirm appointment-change requirements with PSI before relying on a cancellation or rescheduling assumption.
Before you pay, have these items in front of you:
- The correct examination name and your attempt count for it.
- The date of your last attempt and any required wait.
- Confirmation of individual eligibility where a legacy route is involved.
- A plan for booking within the assigned authorization period.
- Specific study changes, with time to check them using fresh questions.
For a later rehearsal, a 185-question mock examination is planned for launch as part of full NBRC RT Exam (TMC) prep. Your next step now is to confirm the earliest permitted retest date, then choose a realistic appointment that leaves room to address the weaknesses you have identified.
