CRT Requirements at a Glance
Becoming a Certified Respiratory Therapist starts long before you sit down at a PSI testing center. The National Board for Respiratory Care (NBRC) sets specific academic and administrative prerequisites you must satisfy before you're even allowed to schedule the Therapist Multiple-Choice (TMC) Examination. Get any one of these wrong - an unaccredited program, a missed application window, an incomplete fee payment - and you'll be stuck rescheduling instead of testing.
This guide walks through every eligibility requirement for the CRT credential as it stands for the 2026 testing cycle, including the education path, the application mechanics, and what the exam itself actually measures once you're cleared to sit for it. If you want a deeper breakdown of exam content after you've confirmed eligibility, see our CRT Exam Domains 2026: Complete Guide to All 3 Content Areas.
Education Prerequisites: The CoARC Requirement
The single biggest eligibility gate is your academic program. To qualify for the TMC exam, you must graduate with at least an associate degree from a respiratory therapy program that is either accredited or supported by the Commission on Accreditation for Respiratory Care (CoARC). This isn't optional or flexible - the NBRC verifies program accreditation status as part of the application process.
Practically, this means:
- A degree in a general science or unrelated allied health field does not qualify you, even if you've worked in a clinical setting.
- Programs must specifically be entry-to-practice respiratory therapy programs recognized by CoARC - not a related but distinct credentialing pathway.
- An associate degree is the floor; many candidates now complete bachelor's-level respiratory therapy programs, which also satisfy this requirement.
If you're mid-program and unsure whether your school qualifies, confirm accreditation status directly with your program director before you invest in exam prep materials. There's no value in mastering the CRT Cheat Sheet 2026: One-Page Review of Must-Know Facts if your degree path doesn't clear you to test in the first place.
Age and Basic Eligibility Rules
Beyond the education requirement, the NBRC requires candidates to be at least 18 years old. Combined with the degree requirement, this means most candidates become eligible right around graduation from their respiratory therapy program - there's no separate work-experience clock you need to run out before applying.
Unlike some allied health certifications that require a period of supervised clinical hours after graduation, the CRT pathway ties eligibility directly to program completion and age. This is one of the reasons the CRT is often the first credential a graduating respiratory therapy student pursues, ahead of the more advanced RRT-track examination (the Clinical Simulation Examination, or CSE).
Key Takeaway
If you're 18 or older and on track to graduate from a CoARC-supported program, you meet the baseline requirements - the real preparation work is passing the TMC exam itself, not clearing bureaucratic hurdles.
Application Process and Fees
Once your education requirement is satisfied, you apply through the NBRC and pay the applicable fee for PSI's computer-based exam. Here's the current fee structure:
| Applicant Type | Fee |
|---|---|
| New applicant | $190 |
| Repeat applicant | $150 |
These fees apply to the TMC Examination under the blueprint that has been in effect since January 2020 and runs through December 2026. Application deadlines matter: TMC applications for the current cycle close on December 15, 2026, with testing itself ending December 31, 2026. Miss that window and you're pushed into a completely different exam format starting in 2027 (more on that below).

TMC Exam Format You're Qualifying For
Understanding what you're qualifying to sit for helps you plan your prep timeline realistically. The TMC Examination is a computer-based test consisting of 160 multiple-choice questions total: 140 are scored, and 20 are unscored pretest items used by NBRC to evaluate future questions. You won't know which items are pretest, so treat every question as if it counts.
- Time limit: 3 hours
- Format: Multiple-choice, computer-based, delivered via PSI testing centers
- Guessing penalty: None - there's no reason to leave a question blank
- Tools: An onscreen calculator is available during the exam
Because there's no penalty for guessing, your strategy should prioritize answering every question rather than leaving blanks for unanswered items you weren't sure about. For a broader look at how difficult candidates find this format in practice, read How Hard Is the CRT Exam? Complete Difficulty Guide 2026.
What the Three Domains Demand From You
The TMC blueprint organizes scored content into three domains, and the distribution is heavily weighted toward one area in particular. Knowing this weighting should directly shape how you allocate study time.
Domain 1: Patient Data
Covers interpreting patient history, physical exam findings, and diagnostic data relevant to respiratory care decisions.
- Accounts for 50 of the 140 scored items
- Requires comfort reading labs, vitals, and imaging in a clinical decision-making context
Domain 2: Troubleshooting and Quality Control of Devices, and Infection Control
Focuses on equipment function, malfunction recognition, and infection control protocols in respiratory care settings.
- Accounts for 20 of the 140 scored items
- Tests practical, hands-on knowledge of devices you'll use daily on the job
Domain 3: Initiation and Modification of Interventions
The largest domain by far - covers initiating and adjusting therapeutic interventions based on patient status.
- Accounts for 70 of the 140 scored items - exactly half the scored exam
- Demands deep familiarity with treatment protocols, not just recognition of terminology
With Domain 3 alone making up half the scored questions, candidates who under-study intervention-based content are taking on unnecessary risk. For a full walkthrough of each domain's subtopics and sample question styles, see CRT Exam Domains 2026: Complete Guide to All 3 Content Areas.
Low Cut vs High Cut: Why It Matters for Eligibility
One requirement that's easy to overlook: the TMC Examination has two distinct performance thresholds, and which one you clear determines what credential path opens up.
- Low cut score: Meeting this threshold earns you the CRT credential.
- High cut score: Meeting this threshold also establishes eligibility for the Clinical Simulation Examination (CSE) - but only when you've also met the separate RRT admission requirements.
In 2025, NBRC reported low-cut pass rates of 78.5% for new candidates and 48.9% for repeat candidates, while high-cut pass rates were 68.2% for new candidates and 29.4% for repeat candidates. These numbers illustrate a meaningful gap: clearing the bar for CRT is notably more common than clearing the higher bar that also unlocks CSE eligibility. For the full data breakdown and what it implies about first-attempt strategy, read CRT Pass Rate 2026: What the Data Shows and CRT Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
If your long-term goal includes RRT, aim your preparation at the high cut score from the start - retaking the TMC later solely to clear a higher threshold costs both time and the $150 repeat fee.
After You Qualify: Maintaining the CRT
Meeting the initial requirements and passing the TMC exam isn't the end of the eligibility story - the CRT credential operates on a five-year maintenance cycle. During each cycle, you'll complete quarterly assessments, and depending on your performance on those assessments, you'll owe 0, 15, or 30 continuing education (CE) credits. There's also an exam-based renewal route available as an alternative for eligible credential holders.
The Continuing Competency Maintenance Program (CMP) fee is $125 per five-year cycle, typically collected as $25 annually. Budgeting for this ongoing cost is part of realistically qualifying for - and keeping - the credential long term.
The 2027 Exam Changeover
If you're planning your eligibility timeline around 2026, you need to know about a structural change coming right after. TMC applications close December 15, 2026, and testing under the current blueprint ends December 31, 2026. Starting January 4, 2027, a replacement exam - the Respiratory Therapy Examination - takes over.
| Feature | TMC (through 2026) | Respiratory Therapy Exam (from 2027) |
|---|---|---|
| Total questions | 160 (140 scored + 20 pretest) | 185 (160 scored + 25 pretest) |
| Time limit | 3 hours | 4 hours |
| New applicant fee | $190 | $360 |
| Repeat applicant fee | $150 | $300 |
| Cut scores | Separate low/high cuts | Retains separate CRT and RRT cut scores |
These are two entirely different question banks - don't mix 2026 TMC prep material with anything referencing the 2027 exam, and don't assume fee or format details carry over. If your graduation timeline lands close to the end of 2026, factor the application deadline into your planning immediately; missing it means testing under a longer, more expensive exam format instead.

Who Actually Hires CRT Holders
Meeting NBRC's requirements and earning the CRT credential opens doors specifically in respiratory care delivery settings. Employers typically include:
- Hospitals, particularly in critical care, emergency, and pulmonary units
- Skilled nursing and long-term care facilities that manage ventilator or oxygen therapy patients
- Home healthcare agencies providing respiratory equipment and therapy support
- Outpatient pulmonary rehabilitation clinics

Frequently Asked Questions
No. The core requirements are age (18 or older) and graduation with at least an associate degree from a CoARC-supported or accredited respiratory therapy program. There's no separate mandatory work-experience period built into TMC eligibility.
You can reapply as a repeat applicant, which carries a $150 fee instead of the $190 new-applicant fee. Repeat candidates historically pass at lower rates than new candidates, so it's worth reviewing weak domains before rescheduling.
Yes. Meeting the TMC's low cut score earns the CRT credential. Meeting the higher cut score also establishes CSE eligibility, but only if you separately meet RRT admission requirements - clearing the high cut score alone isn't sufficient for RRT.
You can, but applications for the current blueprint close December 15, 2026, and testing ends December 31, 2026. If you miss that window, you'll test under the new Respiratory Therapy Examination starting January 4, 2027, which has different fees and format.
It operates on a five-year maintenance cycle involving quarterly assessments and a CE credit requirement of 0, 15, or 30 credits depending on performance, plus a $125 CMP fee per cycle (billed at $25 annually), or an eligible exam-based renewal alternative.
