CSE vs RT Exam in 2027: Choosing a Route After the TMC High Cut

How eligible candidates with a prior TMC high-cut result can compare the CSE and new RT Exam in 2027, including format, remaining fees, attempts and legacy admission questions.

Short answer

NBRC permits qualifying candidates with a prior TMC high-cut result to complete the CSE through the end of 2027 or earn the RRT at the new RT Exam's high cut if they meet RT admission requirements. The RT Exam first runs on January 4, 2027. Choose by confirmed eligibility, readiness for the examination format, remaining fees and the time available to complete the CSE; the TMC high cut alone does not establish admission.

Who actually has a choice between the CSE and RT Exam?

NBRC's CSE page and transition announcement give qualifying candidates with a prior TMC high-cut result two routes to the RRT in 2027: complete the CSE or meet the new RT Exam's high cut. The CSE remains available to that eligible group through the end of 2027, while the first RT administration is January 4, 2027, as checked November 3, 2026.

That choice depends on admission, not just the score printed on an old report. You must meet the full requirements for the examination you choose. Start with these checks:

  1. Confirm your TMC result and date. The CSE transition applies to qualifying high-cut candidates from before the 2027 change. NBRC notices differ in how they phrase the precise final-day cutoff, so ask NBRC to confirm an edge case involving the last day of 2026.
  2. Confirm current CSE eligibility. A high-cut result alone is insufficient. Have NBRC resolve any question about your education or legacy admission route before you build a CSE schedule.
  3. Confirm RT eligibility separately. The RT page lists the CoARC-supported or accredited entry-into-practice program route, with graduation and at least an associate degree, and also lists a CSRT RRT credential route. Its admission requirements include a minimum age of 18.

If your uncertainty is whether you reached the high cut, start with the TMC cut-score and credential guide. Return to this decision only after you know which examinations NBRC will allow you to take.

How do the remaining exams differ in format?

Both examinations allow four hours, but the work inside that time differs. These specifications come from NBRC's CSE and RT pages, checked November 3, 2026.

NBRC says the RT Exam combines knowledge breadth and clinical judgment. Its announcement connects the breadth content to the TMC and the depth content to the CSE's patient conditions, settings, ages and clinical activities. Moving to the RT Exam therefore calls for reviewing the whole RT outline, even if your earlier TMC preparation was strong. The guide to TMC content and the replacement RT outline explains that content bridge.

Use NBRC's free CSE practice simulation and free RT practice examination to inspect the two formats. Record where you lose time and what you need to relearn. That is a more useful preparation comparison than treating a simulation problem as equivalent to one multiple-choice item.

If you choose RT, full NBRC RT Exam (TMC) prep planned for launch includes a 185-question mock exam for a full-length rehearsal. Match the format of your rehearsal to the examination you actually intend to book.

What does each route cost from this point?

Compare the fees you still need to pay. A TMC fee you already paid is a past expense, so including it again can obscure the choice now facing you.

Next examinationNew applicant feeRepeat applicant fee
CSE$200$200
RT Exam$360$300

These are NBRC's published fees, checked November 3, 2026. Verify the amount for your application before paying for a 2027 appointment. Previous TMC or CSE attempts should not be treated as proof that you qualify for the RT repeat fee.

For example, someone who has already passed the TMC and is considering a first CSE attempt compares a $200 CSE fee with a $360 first RT fee. Someone who has already attempted the CSE still sees a published $200 CSE repeat fee. Add your own travel and preparation expenses separately, using actual quotes or amounts you expect to spend.

The lower examination fee is one factor. Also consider whether your preparation matches the format and whether your plan fits the remaining CSE window. Write down the next-attempt cost for each eligible route before deciding.

How do previous attempts affect the decision?

NBRC's RT page states that earlier TMC and CSE attempts do not count toward RT attempts. Under the RT policy checked November 3, 2026, candidates have three attempts before a minimum 120-day waiting period applies between subsequent attempts.

The reset concerns the attempt count. It does not establish admission or make an appointment available on a particular day. If you are considering another CSE attempt, confirm the waiting period that applies to your own history and whether it fits before the CSE closes at the end of 2027. Keep three separate notes: past CSE attempts, past RT attempts, and the earliest next date NBRC permits for each.

NBRC also says an existing CRT is retained if a candidate's RT score falls below the low cut. That answers a credential concern, but it does not remove the cost or preparation needed for another attempt.

Use previous difficulties to choose review tasks. If you change to RT, full NBRC RT Exam (TMC) prep planned for launch includes 1,100 questions across four outline areas for broad review. Check the full outline rather than assuming that practice for a previous CSE attempt covers every RT task.

What if I used a CRT-to-Registry route?

Confirm your individual eligibility directly with NBRC. Its RT page states that CRT-to-Registry admission ends at the close of 2026, as checked November 3, 2026. A past eligibility decision or a CRT credential by itself should not be treated as approval for a 2027 examination.

Ask NBRC to resolve these points before payment:

  • Whether your prior TMC high-cut result and admission history permit CSE completion during 2027.
  • Whether you meet the RT admission requirements independently.
  • Whether any missing documentation must be supplied before an application can proceed.

This is especially important when your original path differed from the CoARC program route. Keep NBRC's answer with your planning records and base your schedule on the route it confirms.

How do I choose my next step without rushing?

Use this editorial checklist once both eligibility questions are settled. It is a planning aid, not an NBRC rule or a claim that either examination is easier.

  1. Name your available route or routes. Remove any option NBRC has not confirmed for your circumstances.
  2. Try the official formats. Note whether your gaps concern knowledge, clinical decisions, pacing or unfamiliar software.
  3. Compare the remaining expense. Include the correct application fee and your own preparation and travel budget.
  4. Put the completion window on your calendar. For CSE, allow time to study, secure an available appointment and respond to an unsuccessful attempt if your applicable waiting period permits. Avoid building a plan that depends on a final available seat.
  5. Choose a preparation target and reassess it. Review your progress before paying or committing to travel.

For an RT baseline, use the 20 free NBRC RT Exam practice questions, then organize your available weeks with the free RT Exam study plan. Treat a short practice set as a way to identify review tasks; it cannot determine whether you would earn the RRT.

For recall work alongside that plan, full NBRC RT Exam (TMC) prep planned for launch includes 500 flashcards. Your immediate next step is to confirm eligibility, inspect the official format and write down a realistic date and remaining budget for the route you select.
