RRT Meaning

What RRT Means in Respiratory Care

In respiratory care, RRT stands for Registered Respiratory Therapist. It is the advanced-level credential for respiratory therapists in the United States, and it signals that a clinician has passed a two-stage national assessment covering both knowledge recall and applied clinical decision-making. If you have seen the acronym elsewhere and wondered whether it is the same thing, this article covers only the respiratory therapy credential and nothing else.

The phrase is used in two ways. As a credential, "RRT" is what appears after a therapist's name on a badge, résumé, or state license application. As a job description, employers often write "RRT" in postings to mean a respiratory therapist who holds the registry-level credential rather than only an entry-level one. If you want the shortest possible definitions, our companion pages on what RRT stands for and what RRT is cover the basics, while this page goes deeper on how the credential is structured.

Who Issues the Credential

The RRT credential is issued by the National Board for Respiratory Care (NBRC). The NBRC writes the examinations, sets the eligibility rules, administers the credential maintenance program, and publishes the Candidate Handbook that governs testing policies. Examinations are delivered at supervised PSI assessment centers. Live remote proctoring ended on December 31, 2024, so initial at-home examination delivery is not a current option.

That distinction matters because the credential is separate from a state license. Most states require a license to practice respiratory care, and the NBRC credential is commonly used as part of qualifying for one, but licensure rules are set by each state. For a fuller picture of the credential itself, see our overview of RRT certification.

What a Registered Respiratory Therapist Does

An RRT evaluates, treats, and monitors patients with breathing and cardiopulmonary problems. The examination structure mirrors this daily work: gathering patient data, keeping equipment safe and functional, controlling infection, and starting or changing interventions based on a patient's response. Concrete topics a candidate must master include:

• Patient assessment: interpreting breath sounds, vital signs, oxygenation and ventilation indicators, arterial blood gas results, and imaging findings.
• Airway management: selecting and maintaining artificial airways and recognizing when a patient needs escalation of support.
• Mechanical ventilation: choosing modes, adjusting settings, and responding to alarms and changes in patient status.
• Aerosol and oxygen therapy: matching devices and medications to the clinical situation.
• Equipment troubleshooting: diagnosing problems and performing quality control on devices.
• Infection control: applying precautions and maintaining clean equipment practices.

The CSE in particular is built around adult chronic airways disease, trauma, cardiovascular, neurological or neuromuscular, and medical or surgical patients, plus pediatric and neonatal cases. That patient mix is a good indicator of the breadth the credential expects.

How the Credential Is Earned: TMC Then CSE

The current 2026 route to RRT is a sequence of two separate examinations, not one long appointment:

1. Therapist Multiple-Choice Examination (TMC). You must reach the high cut score. A lower cut score on the same exam leads to a different, entry-level result, and the TMC alone does not award RRT.
2. Clinical Simulation Examination (CSE). You must pass this interactive exam, which also requires CRT status and a qualifying high-cut TMC result.

Because the two exams test different skills, candidates often find they are stronger at one than the other. Our difficulty guide discusses why the simulation format surprises people who are comfortable with multiple choice.

The Six Exam Objective Headings

The study material for this site organizes content into six headings. It is important to read these correctly: Domains 1 to 3 are official TMC exam-objective headings, and Domains 4 to 6 are official CSE exam-objective headings. Six is the count of headings across two assessments, not a single combined six-domain RRT exam, and no combined TMC/CSE weights are published. The repeated headings are intentional, as is the small wording difference between "Devices" and "Equipment."

Interventions carries the largest TMC allocation, so it deserves the most study hours on the multiple-choice side. For a deeper treatment, see our full RRT exam domains guide.

How the CSE Assembles Its Cases

The CSE draws its 20 scored problems from case-assembly groups. These are groupings for how the exam is built, not extra domains and not editorial weights:

Chronic airways disease appears most often, which makes sense for a profession built around asthma, COPD, and related conditions.

Exam Format, Fees, and Rules

Standard first attempts total USD 390, or USD 350 with the one-time USD 40 first-CSE discount available to eligible AARC members through the prescribed application process. These figures exclude education, preparation materials, membership, and licensure. For a full budget, see the RRT certification cost breakdown.

Each CSE problem can contain multiple sections and choices, and the 2026 Candidate Handbook specifies one CSE score summed across the examination rather than separate pass thresholds for information gathering and decision making. Current numeric cut scores are unverified, so treat any specific number you see elsewhere with caution; our passing score page explains what is and is not known.

Eligibility and Legacy Routes

Standard eligibility requires being age 18 or older and holding at least an associate degree from an eligible CoARC-supported or accredited entry-into-practice respiratory program. The CSE additionally requires CRT status and a qualifying high-cut TMC result.

Several conditional legacy CRT routes also exist:

• Four CRT years plus 62 specified college hours
• Two CRT years plus a qualifying respiratory associate degree
• Two CRT years plus a non-respiratory bachelor's degree and 62 specified hours
• A separately listed CSRT route to RRT

These exceptions do not automatically continue into the 2027 pathway. Details are in our RRT requirements guide.

What the 2025 Pass Data Shows

The NBRC's calendar-2025 figures are reported by examination and by attempt type. They are separate cohorts, not a combined probability of earning RRT, so do not multiply or average them.

Reported activity for 2025 was 11,086 TMC administrations, 9,004 CSE administrations, and 5,196 RRT credentials awarded. The gap between new and repeat TMC high-cut rates is the most telling feature: a first attempt with solid preparation tends to go much better than a rushed retake. See our pass rate analysis for context.

Where RRTs Work and Who Hires Them

Registered Respiratory Therapists are employed wherever patients need breathing support or cardiopulmonary monitoring. Typical employers include:

• Hospitals, especially intensive care units, emergency departments, and general inpatient floors
• Neonatal and pediatric units, which tie directly to the CSE's pediatric and neonatal case groups
• Long-term acute care and skilled nursing facilities serving patients on chronic ventilation
• Home care and durable medical equipment providers managing oxygen and home ventilators
• Pulmonary rehabilitation and sleep programs

Many postings prefer or require the registry-level credential for critical care and ventilator-management roles. Explore current openings in our RRT jobs overview, and see the salary guide and ROI analysis for the career case.

Keeping the Credential Active

RRT holders maintain the credential through the NBRC's five-year Credential Maintenance Program (CMP), with a published exemption for credentials earned before July 1, 2002. Three routes are available:

• Assessment-based continuing education, requiring zero, 15, or 30 Category I credits depending on performance
• Passing the highest relevant examination during the final year of the maintenance cycle
• Earning an additional qualifying NBRC credential

CMP payment is USD 25 per payment year before 2027 and USD 30 beginning in 2027. The CMP brochure shows a mix of old and new fee versions in places, but the live issuer FAQ confirms the 2027 effective date.

The 2027 Transition

The path described above is changing. A single Respiratory Therapy Examination takes effect in January 2027 with 185 multiple-choice questions (160 scored, 25 pretest) and four hours allowed. Fees are USD 360 new and USD 300 repeat, and lower and higher cut scores lead directly to CRT or RRT. Applications opened October 1, 2026, and first availability is January 4, 2027.

Key dates for the current route:

• TMC applications close December 15, 2026, and TMC testing ends December 31, 2026.
• CSE remains available through December 31, 2027, but only for the eligible transition cohort.
• The CRT-to-registry admission policy expires December 31, 2026.

Do not blend the future outline into your current prep. The new exam has its own content outline, so keep TMC and CSE study separate from it. Check the exam dates page for scheduling details.
