- Renewal options include earning 30 CE hours, retesting on the TMC, or earning a new NBRC credential - you choose which path fits your situation.
- The TMC as currently structured is replaced by the new Respiratory Therapy Examination starting January 1, 2027; act before the deadline if retesting.
- Retesting on the TMC costs $150 USD as a repeat applicant - $40 less than the $190 new-applicant fee.
What TMC Recertification Actually Means
Recertification is not a formality. For respiratory therapists holding a credential issued or maintained through the National Board for Respiratory Care, it is the mechanism that keeps your professional standing active and demonstrates to employers, licensing boards, and patients that your competency has been formally verified within a defined window.
The TMC - the Therapist Multiple-Choice Examination administered by the NBRC through PSI assessment centers and eligible remote proctoring locations - is the entry gateway to both the CRT (Certified Respiratory Therapist) and RRT (Registered Respiratory Therapist) credentials. Once earned, those credentials do not simply persist indefinitely. They require active maintenance under the NBRC's structured Continuing Competency Program.
Understanding exactly what that maintenance requires, what it costs, and how the upcoming 2027 exam restructuring affects current credential holders is critical if you want to avoid a lapse. This article breaks down every element of that process with specificity.
The NBRC Continuing Competency Program Explained
The NBRC Continuing Competency Program operates on a 5-year maintenance cycle. Every credential holder must satisfy the program's requirements within each 5-year period to keep their CRT or RRT active. There is no passive renewal - you must take a deliberate action, pay the required fees, and document your activity through NBRC's system.
The Three Pathways to Renewal
Within the 5-year window, credential holders choose one of the following options to demonstrate continued competency:
- Continuing Education (CE) Hours: Earning 30 hours of approved CE credit from accredited or NBRC-recognized sources.
- Retesting: Sitting for and passing a qualifying NBRC examination - including the TMC - under the current exam structure.
- Earning a New Credential: Successfully obtaining an additional NBRC credential (such as the NPS, ACCS, or SDS specialty credential) resets your maintenance clock.
Each pathway has different cost implications, preparation burdens, and strategic advantages depending on your career stage. The section below on costs makes those differences concrete.
Key Takeaway
The CE path requires 30 hours of documented continuing education within your 5-year cycle. The retesting path requires you to pass a qualifying exam. Earning a specialty credential satisfies both goals simultaneously - it advances your career and fulfills maintenance requirements.
Exact Requirements to Maintain Your Credential
The NBRC structures its requirements in two layers: the annual fee obligation and the 5-year renewal activity. Both must be satisfied. Letting either lapse can jeopardize your credential status.
Annual Fee Requirement
Credential holders owe an annual fee to the NBRC to keep their active status. This fee is separate from any examination or CE costs. It is not optional - non-payment triggers a credential lapse regardless of whether you have completed CE hours or other renewal activities.
5-Year Renewal Activity
Before the end of each 5-year maintenance period, you must complete and document one of the three renewal pathways described above: 30 CE hours, retesting, or a new credential. The NBRC tracks your maintenance window from the credential award or most recent renewal date.
Credential Maintenance Checklist
Before your 5-year window closes, verify all of the following are complete:
- Annual fees paid for each year within the cycle
- One renewal activity documented: 30 CE hours, exam passed, or new credential earned
- All documentation submitted to NBRC before the deadline - late submissions are not retroactively applied
- NBRC account information current (email, employer, address) to receive deadline notifications
Education Prerequisites Are Not Re-Verified
For recertification purposes, you are not re-establishing eligibility from scratch. The original prerequisites - including graduation from a CoARC-accredited respiratory therapy entry program with an associate degree or higher and being at least 18 years old - were verified at initial application. Renewal focuses on demonstrated ongoing competency, not re-verification of your educational background.
Costs, Fees, and Annual Obligations
The financial picture of TMC recertification has several components. For a detailed breakdown of all costs across the credentialing lifecycle, see our TMC Certification Cost 2026: Complete Pricing Breakdown. Here we focus specifically on the recertification-relevant fees.
| Fee Type | Amount | Notes |
|---|---|---|
| TMC Exam - New Applicant | $190 USD | Initial credentialing only; not applicable to retesting |
| TMC Exam - Repeat Applicant | $150 USD | Applies when retesting for renewal; $40 savings vs. new applicant fee |
| Annual NBRC Credential Maintenance Fee | Varies (set by NBRC) | Due each year; must remain current to avoid lapse |
| CE Hours (30 required) | Varies by provider | Cost depends on CE source; some employers subsidize |
The repeat applicant exam fee of $150 is a meaningful consideration when choosing the retesting path. If you are someone who learns well through structured exam preparation and prefers a clear, testable outcome over tracking CE hours, the $150 cost is relatively contained - especially weighed against the career earnings impact analyzed in our Is the TMC Certification Worth It? Complete ROI Analysis 2026.
The 2027 Exam Transition: What Changes for Credential Holders
This is the single most time-sensitive element of 2026 recertification planning.
The NBRC has announced that the current TMC/CSE examination pathway will be replaced by a new Respiratory Therapy Examination effective January 1, 2027. The current TMC - 160 multiple-choice questions (140 scored, 20 pretest), 3 hours, two cut scores for CRT and RRT/CSE eligibility - operates under the NBRC's detailed content outline effective through December 31, 2026.
What this means for recertification:
- If you plan to retestate using the current TMC format, you must schedule and sit for that exam before December 31, 2026. The current content outline, question style, and scoring structure apply only through that date.
- Credential holders are not immediately affected in their CRT/RRT status by the 2027 transition - your existing credential does not expire because the exam format changes. Your 5-year maintenance cycle continues on its own timeline.
- Future recertification retesting will occur under the new Respiratory Therapy Examination structure once it launches. The exact format and fee structure of that new exam have not yet been fully detailed for public planning purposes.
Choosing the Retesting Path: What You Need to Know
For credential holders who elect the retesting pathway, passing the TMC as a repeat applicant is substantively the same process as the original exam - same 160-question format, same 3-hour time limit, same PSI testing centers and remote proctoring options, same two cut scores determining CRT and RRT eligibility.
The difference is context. You are not sitting the exam for the first time with fresh clinical training memories. Depending on how many years have passed since your initial credentialing, certain content areas may feel less current. That makes targeted domain review more important than broad-based study.
For a realistic assessment of the exam's difficulty before committing to this path, read How Hard Is the TMC Exam? Complete Difficulty Guide 2026. The exam is rigorous regardless of whether you are a first-time or repeat applicant.
Exam Eligibility Reminder for Repeat Applicants
You must apply through the NBRC, pay the $150 repeat applicant fee, and receive an Authorization to Test (ATT) before scheduling with PSI. The same testing center network and remote proctoring options available to new applicants apply to credential holders retesting for renewal.
Building Your Recertification Timeline
Whether you choose CE hours or retesting, the worst outcome is discovering your deadline has passed. Build backward from your maintenance window close date.
Assessment and Decision
- Log into your NBRC account and confirm your exact maintenance window close date
- Verify annual fees are current - address any lapse immediately
- Decide: CE path, retesting path, or new credential path
- If retesting before December 31, 2026: confirm the TMC content outline is still active for your planned test date
Preparation Launch
- If retesting: begin focused domain review, prioritizing Domain 3 (50% of scored content)
- If CE path: identify approved CE providers and register for enough hours to reach 30 before your deadline
- Run a diagnostic practice test at TMC Exam Prep to identify knowledge gaps before full study begins
Application and Scheduling
- Submit NBRC application and pay $150 repeat applicant fee
- Schedule PSI exam date - do not wait for your ATT to arrive before identifying available test windows
- Intensify Domain 1 and Domain 3 review; complete Domain 2 troubleshooting refresher
Final Preparation
- Complete timed full-length practice exams at TMC Exam Prep
- Review exam-day logistics: PSI location, required ID, prohibited items
- Confirm your NBRC account will reflect the passed exam for maintenance documentation
Refreshing Your Domain Knowledge Before Retesting
The TMC tests across three domains. For credential holders retesting after years in clinical practice, the domain weighting should directly determine where you invest preparation time. The exam is not clinically intuitive - it is standardized, and the question style rewards specific knowledge recall over general experience. Our complete TMC Exam Domains 2026: Complete Guide to All 3 Content Areas covers all three in depth.
Domain 1: Patient Data Evaluation and Recommendations (36%)
This domain covers interpretation of clinical data, diagnostic results, and recommendation-making. It accounts for over a third of your scored questions and tests analytical skills that remain central to respiratory therapy practice.
- ABG interpretation and acid-base balance assessment
- Pulmonary function test result analysis
- Radiographic and laboratory data interpretation
- Patient history and physical assessment findings
Full study guide: TMC Domain 1: Patient Data Evaluation and Recommendations (36%) - Complete Study Guide 2026
Domain 2: Troubleshooting and Quality Control of Equipment and Infection Control (14%)
At 14% of the exam, this is the smallest domain - but it is specific and highly testable. Equipment malfunction scenarios and infection control protocols are frequently missed by candidates who underestimate the precision required.
- Ventilator alarm troubleshooting and circuit problem identification
- Oxygen delivery device calibration and verification
- Standard and transmission-based precautions
- Equipment quality control procedures
Full study guide: TMC Domain 2: Troubleshooting and Quality Control of Equipment and Infection Control (14%) - Complete Study Guide 2026
Domain 3: Initiation and Modification of Interventions (50%)
Half of your exam score comes from this single domain. It covers the breadth of respiratory therapy interventions - from mechanical ventilation initiation to pharmacological management to airway care. This is where retesting candidates must spend the majority of their preparation time.
- Mechanical ventilation modes, settings, and weaning protocols
- Bronchopulmonary hygiene and airway clearance techniques
- Medication administration, dosing, and monitoring
- Oxygen therapy, humidity, and aerosol delivery
- Neonatal and pediatric respiratory care interventions
- Emergency and critical care management procedures

Frequently Asked Questions
NBRC credentials are maintained through the Continuing Competency Program on a 5-year cycle. Within each cycle, you must pay annual maintenance fees and complete one renewal activity: earning 30 CE hours, retesting on a qualifying exam, or earning a new NBRC credential. Both the annual fee and the 5-year renewal activity are required - satisfying only one is not sufficient.
The repeat applicant fee for the TMC is $150 USD, compared to $190 for new applicants. This covers only the exam fee. Annual NBRC credential maintenance fees are separate obligations paid regardless of which renewal pathway you choose. See our TMC Certification Cost 2026: Complete Pricing Breakdown for full cost context.
No. The current TMC/CSE examination pathway - including the 160-question, 3-hour format with the current content outline - is only available through December 31, 2026. Beginning January 1, 2027, the NBRC replaces it with the new Respiratory Therapy Examination. Credential holders who want to use the current TMC format for their retesting renewal path must sit the exam before that deadline.
No. The 2027 exam format change does not automatically expire existing CRT or RRT credentials. Your credential remains active as long as you satisfy your 5-year maintenance cycle requirements and pay your annual fees. The change affects the examination used for future retesting renewal - not the credentials already held by current practitioners.
Domain 3 - Initiation and Modification of Interventions - should receive the most preparation time because it constitutes 50% of the exam's scored content. That is a larger share than Domain 1 (36%) and Domain 2 (14%) combined relative to its weight. Follow that with Domain 1 given its 36% contribution. Domain 2 at 14% requires targeted review of equipment troubleshooting and infection control specifics that may not surface regularly in day-to-day clinical practice.
