RRT Requirements 2026: Eligibility, Prerequisites & How to Qualify

What "Qualifying" Means for the Registered Respiratory Therapist Credential

The Registered Respiratory Therapist credential is awarded by the National Board for Respiratory Care (NBRC). In 2026, qualifying is not a single event. You must first meet eligibility requirements to sit for the exams, then pass two separate examinations in a specific order. Many candidates confuse "eligible to apply" with "qualified for the credential," and that confusion causes missed deadlines and wasted fees.

If you are still orienting yourself to the credential itself, our explainers on what RRT certification is and what RRT stands for cover the basics. This article focuses on the gatekeeping questions: who can apply, in what sequence, by what date, and at what cost.

The Standard Eligibility Route

The standard route is straightforward. A candidate must:

• Be 18 years of age or older.
• Hold at least an associate degree from an eligible entry-into-practice respiratory program that is CoARC-supported or accredited.

For the CSE specifically, there are two additional conditions. You must hold CRT status and you must have achieved a qualifying high-cut TMC result. In other words, the high cut score on the TMC is both the pathway to the CSE and the gate that separates the registry-level track from the lower-level outcome.

Program accreditation is the most common sticking point

Graduates of eligible programs rarely have trouble, but candidates from non-standard or transitional programs should confirm their program's status directly with the NBRC before paying any exam fee. Program standing, not just a diploma, determines whether you can apply.

The Two-Exam Sequence: TMC Then CSE

The current RRT route runs through two distinct assessments. They are separate exams with separate fees, separate appointments, and separate pass rates. They are not one combined 182-question sitting.

Two points deserve emphasis. First, the TMC can produce a lower or higher cut outcome, and only the higher cut opens the CSE door. Second, the 2026 Candidate Handbook specifies a single CSE score summed across the exam, rather than separate information-gathering and decision-making pass thresholds. Older prep materials that describe two separate section thresholds are out of date on this point. Current numeric cut scores are not verified here, so check the NBRC directly; our RRT passing score guide explains how to read the scoring information.

Conditional Legacy CRT Routes

Some candidates already hold the CRT credential and qualify through experience-based pathways rather than the standard associate-degree route. The legacy routes include:

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

These routes are conditional. The NBRC does not automatically carry these exceptions into the 2027 pathway, so a candidate relying on a legacy route should treat the 2026 window as the safest time to use it. If you are in this group, confirm your specific route and documentation requirements with the NBRC before applying, because the "specified college hours" rule is the detail most likely to trip up applicants.

2026 Deadlines and the 2027 Transition

The calendar is the single most important qualification factor this year. Here is what the published transition timeline establishes:

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

There is also an unresolved wording issue. The issuer's language about achieving the TMC high cut "prior to December 31, 2026" conflicts with the announced final testing date. If your plan depends on a result earned on December 31 itself, get written confirmation from the NBRC before relying on it. Do not leave your entire qualification to the final day of testing.

The 2027 single-exam pathway

Starting in 2027, a new Respiratory Therapy Examination takes over. It contains 185 multiple-choice questions (160 scored, 25 pretest) with four hours allowed, at USD 360 for new candidates and USD 300 for repeat. Its lower and higher cut scores lead directly to CRT or RRT. Applications opened October 1, 2026, and the first examination availability is January 4, 2027. This is a separate future scope with its own content outline, and it should not be blended with the TMC and CSE domains discussed below.

For a full breakdown of scheduling windows, see our guide to RRT exam dates, deadlines and scheduling.

Fees, Attempts, and Exam-Day Rules

What the exams cost

Standard first attempts total USD 390 (USD 190 for the TMC plus USD 200 for the CSE). Eligible AARC members can claim a one-time USD 40 discount on their first CSE through the prescribed application process, bringing the total to USD 350. These figures exclude your education, preparation materials, membership dues, and state licensure. For a fuller budget, see the RRT certification cost breakdown.

Attempt limits and waiting periods

For each examination, three initial attempts are permitted without a waiting interval between them. Later attempts require 120 days between attempts. Repeat fees apply, and the repeat TMC fee (USD 150) is lower than the new-candidate fee, while the CSE fee stays at USD 200 either way. Given that repeat-cohort pass rates run noticeably lower, retaking is better treated as a recovery plan than a strategy.

Testing environment

Both exams are delivered at supervised PSI assessment centers. Live remote proctoring ended December 31, 2024, so initial at-home delivery is not a current option. Exams are closed book, and the only calculator allowed is the supplied virtual calculator. Break time counts against your examination time, which matters on the three-hour TMC and the four-hour CSE alike.

What the 2025 data shows

The calendar-2025 figures illustrate why preparation matters. These are separate cohorts, not a combined probability of earning the credential:

Reported activity for the year was 11,086 TMC administrations, 9,004 CSE administrations, and 5,196 RRT credentials awarded. For interpretation, read our RRT pass rate analysis, and for a candid look at difficulty, see how hard the RRT exam is.

What You Must Master Once You Qualify

Meeting the requirements gets you into the exam room; the content outline determines whether you leave with the credential. The NBRC publishes separate detailed content outlines for the TMC (effective January 2020 through December 31, 2026) and the CSE (effective January 2020 through December 31, 2027). The six domain headings below come from those two assessments: three for the TMC and three for the CSE. Six is the count of headings across two assessments, not an official combined six-domain RRT exam. Our RRT exam domains guide goes deeper on each area.

The CSE uses parallel headings: Domain 4 (Patient Data), Domain 5 (Troubleshooting and Quality Control of Equipment, and Infection Control), and Domain 6 (Initiation and Modification of Interventions). Note the intentional wording difference: the TMC says "Devices" while the CSE says "Equipment." The repeated headings reflect that the CSE tests the same competency areas through interactive cases rather than isolated questions. No combined TMC/CSE domain percentages are established, so be skeptical of any source that offers them.

Staging Your Preparation Around the Requirements

Because the two exams run in sequence and the high TMC cut gates the CSE, your study plan should mirror that structure. The timeline below ties preparation to the actual content weighting, not to a generic template.

Once you have the high cut result in hand, shift to case-based simulation practice for the CSE, working through full multi-section patient scenarios across the adult, pediatric, and neonatal groups. For a complete plan, see our RRT study guide and the condensed RRT cheat sheet, and test yourself on the main practice test site.

Keeping the Credential: Maintenance Requirements

Qualifying is not the end of the requirements. Active RRT holders maintain the credential through the five-year Credential Maintenance Program (CMP), with a published exemption for credentials earned before July 1, 2002. Maintenance routes include:

• Assessment-based continuing education: 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. Note that the CMP brochure itself shows mixed old and new fee versions in parts of its text; the live issuer FAQ confirms the 2027 effective date, so use the FAQ as your reference.
