- CRT training targets the TMC exam: 160 questions (140 scored), 3-hour limit, through December 31, 2026.
- Interventions is the heaviest domain, worth 70 of 140 scored items - build your training schedule around it.
- New applicants pay USD 190; repeat applicants pay USD 150, via PSI computer-based testing.
- Meeting the high cut score can also open CSE eligibility if RRT admission requirements are met.
What CRT Training Actually Means
"CRT training" gets used loosely, but for anyone pursuing the Certified Respiratory Therapist credential through the National Board for Respiratory Care (NBRC), it has a specific meaning: preparing for the Therapist Multiple-Choice (TMC) Examination. This isn't generic exam prep - it's targeted preparation against a published blueprint that has been effective since January 2020 and runs through December 2026, covering exact content proportions across three domains.
Before you build a study plan, it helps to understand what you're training toward and why it differs from other exam prep. For a full breakdown of eligibility rules, see CRT Requirements 2026: Eligibility, Prerequisites & How to Qualify, and for a structured walkthrough of the whole preparation process, CRT Study Guide 2026: How to Pass on Your First Attempt is a useful companion to this article.
The Academic Foundation You Need First
CRT training doesn't start with flashcards - it starts with eligibility. Standard entry requirements call for candidates to be at least 18 years old and to have graduated with a minimum of an associate degree from a CoARC-supported or accredited entry-to-practice respiratory therapy program. In other words, your clinical coursework and rotations are the first phase of training; the TMC-focused review is the second phase layered on top.
If you're still finishing your program, your classroom and clinical time already covers much of what the TMC exam tests. The exam-prep phase is about converting that clinical knowledge into fast, accurate multiple-choice performance under time pressure - a different skill than bedside competency, even though the content overlaps heavily.
Key Takeaway
Confirm your program's accreditation status and your projected graduation date before scheduling anything - eligibility is the gate that determines when your training timeline can end.
TMC Exam Mechanics You're Training For
Effective training is built around the actual test format, not assumptions borrowed from other credentialing exams. The TMC Examination, delivered on computer through PSI, consists of 160 multiple-choice questions: 140 scored items plus 20 unscored pretest items mixed in without identification. Candidates get a 3-hour limit to complete the exam, and there's no penalty for guessing, so training should include practice leaving no question blank.
An onscreen calculator is available during the test, which matters for how you train on dosage, ventilator, and gas-law calculations - you don't need to memorize long division tricks, but you do need to practice using an onscreen tool quickly and accurately under time pressure.
Two cut scores matter for your outcome:
- Meeting the low cut score earns the CRT credential.
- Meeting the high cut score also establishes CSE eligibility, provided RRT admission requirements are separately met.
For the exact numeric detail behind these thresholds, see CRT Passing Score 2026: Exactly What You Need to Pass. And if you're trying to gauge how demanding the exam really is relative to your current knowledge, How Hard Is the CRT Exam? Complete Difficulty Guide 2026 breaks that down in more depth.
Training by Domain
The TMC blueprint allocates scored items across three domains, and your training time should mirror that weighting rather than being split evenly. The official scored-item allocation is 50/20/70 across the three domains below, out of 140 scored items total.
Domain 1: Patient Data
This domain tests your ability to gather and interpret clinical information - history, physical exam findings, lab values, imaging, and bedside monitoring - before deciding on a course of action.
- Interpreting arterial blood gases, pulmonary function tests, and chest imaging
- Recognizing abnormal vital signs and hemodynamic data
- Reviewing patient history and recommending additional diagnostic data when needed
Domain 2: Troubleshooting and Quality Control of Devices, and Infection Control
This domain covers equipment assembly, malfunction troubleshooting, calibration and quality control checks, and infection-control protocols across respiratory care devices.
- Identifying and correcting ventilator, nebulizer, and oxygen-delivery device malfunctions
- Performing quality control on blood gas analyzers and other diagnostic equipment
- Applying infection-control procedures during equipment setup and patient contact
Domain 3: Initiation and Modification of Interventions
This is the largest domain by far - 70 of 140 scored items - covering the actual clinical decisions a respiratory therapist makes: starting, adjusting, or discontinuing therapies.
- Initiating and titrating oxygen therapy, mechanical ventilation, and aerosol treatments
- Modifying ventilator settings based on patient response and blood gas trends
- Responding to emergencies, including airway management and resuscitation scenarios
Because Domain 3 carries exactly half the scored weight of the exam, it deserves roughly half your training hours as well. For a deeper dive into each domain's subtopics and sample question styles, see CRT Exam Domains 2026: Complete Guide to All 3 Content Areas.
| Domain | Scored Items | Relative Training Priority |
|---|---|---|
| Patient Data | 50 | Moderate-high |
| Troubleshooting, QC, Infection Control | 20 | Lower |
| Initiation and Modification of Interventions | 70 | Highest |
A Domain-Aware Training Timeline
Generic study techniques like spaced repetition or timed practice blocks only work well when they're mapped to the actual point values above. Here's one way to sequence an eight-week runway that weights time toward Interventions without neglecting the other two domains.
Patient Data Foundations
- Drill ABG interpretation and PFT patterns until they're automatic
- Review chest imaging basics and hemodynamic monitoring values
Interventions Deep Dive
- Work ventilator initiation and titration scenarios daily, since this is 50% of scored content
- Practice oxygen therapy and aerosol delivery decision trees
- Rehearse emergency response and airway management sequences
Troubleshooting and Infection Control
- Review equipment malfunction scenarios and quality control checks
- Confirm infection-control protocol knowledge for common devices
Full-Length Practice and Review
- Take timed, full-length practice sessions at ../ to build 3-hour endurance
- Revisit weak domains identified from practice performance

Registration, Fees, and Deadlines
Part of CRT training is logistical - knowing when and how to register so you're not scrambling near a deadline. New applicants pay a USD 190 fee; candidates retesting pay USD 150. The exam is delivered as a computer-based test through PSI testing centers.
Remember the hard cutoff: TMC applications close December 15, 2026, and testing itself ends December 31, 2026. If your training timeline pushes past that window, you'll be preparing for the January 2027 replacement exam instead, which carries different fees (USD 360 new / USD 300 repeat) and a different question count. Plan your training start date backward from whichever exam version you're actually sitting for.

Training Doesn't Stop at the CRT
Passing the TMC and earning your CRT is a milestone, not a finish line. The credential follows a five-year maintenance cycle involving quarterly assessments, where you'll need 0, 15, or 30 continuing education credits depending on your performance, or you can pursue an eligible examination-based renewal route instead. There's also a Continued Competency and Maintenance Program (CMP) fee of USD 125 per cycle, typically collected as USD 25 annually.
Building light, ongoing review into your professional routine - rather than cramming right before a maintenance deadline - is really an extension of the same domain-weighted training approach you used to pass the TMC in the first place.
Who Hires Candidates Mid-Training
Understanding the job market you're training toward can sharpen your focus. Hospitals, skilled nursing facilities, home care agencies, and outpatient pulmonary clinics all recruit respiratory therapy graduates and CRT holders, often starting the hiring conversation while candidates are still finishing their TMC preparation. Employers commonly look for demonstrated competence in exactly the areas the TMC blueprint tests: ventilator management, oxygen therapy protocols, and diagnostic data interpretation.

Once you're ready to start practicing under realistic timing conditions, full-length practice sessions at the main practice test platform are one of the most direct ways to see how your training is translating into exam-day readiness.
Frequently Asked Questions
There's no fixed number set by the NBRC, since it depends on your program background and practice performance. Many candidates use a multi-week structured plan, weighting time toward Interventions since it carries 70 of 140 scored items.
The same TMC exam serves both purposes. Meeting the low cut score earns the CRT credential, while meeting the high cut score also establishes CSE eligibility if RRT admission requirements are separately met - so strong TMC training benefits both paths.
No. There's no penalty for guessing, so your training should include strategies for eliminating answer choices and never leaving a question unanswered within the 3-hour limit.
If you're eligible and ready before the December 15, 2026 application deadline, training for the current TMC format (160 questions, 140 scored, 3-hour limit) makes sense. If your timeline extends past testing ending December 31, 2026, you'll instead be preparing for the January 2027 replacement exam, which has different question counts, timing, and fees.
You can retest by paying the repeat applicant fee of USD 150. Historical NBRC data shows repeat candidates pass at notably lower rates than first-time candidates, which is a strong argument for thorough domain-weighted training before your first attempt.
