NBRC

The examinations associated with the RRT were developed to objectively measure essential knowledge, skills, and abilities required of advanced respiratory therapists, and to set uniform standards for measuring such knowledge. Effective January 2015, the name of one of the examinations that candidates take to earn the Registered Respiratory Therapist credential changes from the Written Registry Examination to the Therapist Multiple-Choice Examination (TMC). The Therapist Multiple-Choice Examination is designed to objectively measure essential knowledge, skills, and abilities required of entry-level respiratory therapists, as well as determine eligibility for the Clinical Simulation Examination (CSE). The CRT and/or RRT credentials are used as the basis for the licensure in all of the 49 states that regulate the practice of respiratory care.

There are two established cut scores for the Therapist Multiple-Choice Examination. Candidates may become eligible to take the Clinical Simulation Examination by achieving the higher cut score on the Therapist Multiple-Choice Examination. The passing point associated with RRT eligibility is higher than the passing point associated with the CRT credential. Individuals who attempt and pass the Therapist Multiple-Choice Examination at the higher cut score and attempt and pass the Clinical Simulation Examination will be awarded the Registered Respiratory Therapist (RRT) credential. Click here for additional examination Frequently Asked Questions.

The Therapist Multiple-Choice Examination consists of 160 multiple-choice questions (140 scored items and 20 pretest items) distributed among three major content areas: Patient Data Evaluation and Recommendations, Troubleshooting and Quality Control of Equipment and Infection Control, and Initiation and Modification of Interventions. Therapist Multiple-Choice candidates will be given three hours to complete the examination.

The Clinical Simulation Examination consists of 22 problems (20 scored items and 2 pretest items). The clinical setting and patient situation for each problem are designed to simulate reality and be relevant to the clinical practice of respiratory care. Candidates will be given four hours to complete the CSE.

If you are planning to take any of the credentialing examinations offered by the National Board for Respiratory Care, Inc. (NBRC), the Self-Assessment Examination provides an excellent opportunity for you to find out in advance how well you will do. The SAEs are available in web-based format and more information can be found by clicking the Self-Assessment Examination Quick Link.

  

Eligibility Three-Year Time Limit

Effective January 1, 2005, new graduates of accredited advanced-level education programs will have three years after graduation to earn the RRT credential. Individuals who do not earn the RRT credential within this time limit will be required to retake and pass the Therapist Multiple-Choice Examination at the CRT cut score to regain eligibility, and any previous passing performance to earn the RRT credential shall be nullified. Following regaining eligibility by taking and passing the Therapist Multiple-Choice Examination at the CRT cut score, the candidate will have another three years to earn the RRT credential. The individual must apply as a new candidate and pay all applicable fees to take the Therapist Multiple-Choice and Clinical Simulation Examinations.

NBRC's mission is to evaluate the competency of respiratory therapists and to support the profession of respiratory care. It’s a role that we take very seriously. As the provider of the RRT, the credential that is considered the “standard of excellence” in respiratory care, it is our responsibility to ensure that graduates of advanced-level education programs have the opportunity to earn the RRT credential. During a time when there is a shortage of qualified respiratory therapists to provide the excellent care that patients expect, advanced-level graduates who earn the RRT credential are in high demand nationwide and can help to fill this shortage.

Below is a list of questions about the RRT Eligibility Three-Year Time Limit and how it impacts you. NBRC staff is available to answer any other additional questions via phone or email. Contact us at 888-341-4811 or at nbrc-info@nbrc.org.


Why adopt a three-year time limit to pass the RRT Examination after graduating from an advanced-level program?

NBRC approved the three-year time limit in 2005 to ensure that individuals who consider themselves "registry eligible" have taken and passed the RRT Examination and demonstrated their knowledge and competence.

In 2003, the American Association for Respiratory Care (AARC), the Commission on Accreditation for Respiratory Care (CoARC), and the NBRC recognized the RRT credential as the “standard of excellence” for respiratory care professionals. At the request of the AARC and CoARC, NBRC approved a policy on Jan. 1, 2005 that requires graduates of advanced-level programs to earn the CRT and RRT credentials within three years of graduation. The original policy also required advanced-level graduates with an associate degree who had already earned the CRT credential to complete the RRT by February 28, 2009.


What happens if I don’t earn the RRT credential by my three-year deadline?

While the NBRC is dedicated to supporting respiratory therapists, there will be no extension of this deadline.

Individuals who do not earn the RRT credential within this time limit will be required to retake and pass the Therapist Multiple-Choice Examination at the CRT cut score to regain eligibility, and any previous passing performance to earn the RRT credential shall be nullified. After regaining eligibility by taking and passing the Therapist Multiple-Choice Examination at the CRT cut score, the candidate will have another three years to earn the RRT credential. If the candidate achieves the higher cut score on the first attempt, they will receive an additional three years to pass the Clinical Simulation Examination to earn the RRT credential.​ Any previous passing performance prior to the original three-year time limit is considered null and void.

Please note: CRT-to-Registry candidates are not affected by this admissions policy.

CRT-to-Registry Admission Policy

The NBRC continually receives inquiries regarding the “CRT-to-Registry” provision of the admission policies for the examinations associated with the RRT. Below are answers to the most commonly asked questions relating to this alternative route to the examinations associated with the RRT. If you have questions which are not answered below, or if you need further clarification of this admission policy, please contact the NBRC Executive Office.

The CRT-to-Registry provision is as follows:

  • Be a CRT for at least four years prior to applying for the examinations associated with the RRT. In addition, the applicants shall have at least 62 hours of college credit from a college or university accredited by its regional association or its equivalent. The 62 semester hours of college credit must include the following courses: anatomy and physiology, chemistry, microbiology, physics, and mathematics.

OR

  • Be a CRT for at least two years prior to applying for the examinations associated with the RRT.  In addition, the applicant shall have earned a minimum of an associate degree from an accredited entry-level respiratory therapy education program.

OR

  • Be a CRT for at least two years prior to applying for the examinations associated with the RRT.  In addition, the applicant shall have earned a baccalaureate degree in an area other than respiratory care and shall have at least 62 semester hours of college credit from a college or university accredited by its regional association or equivalent.  The 62 semester hours of college credit must include the following courses: anatomy and physiology, chemistry, mathematics, microbiology, and physics.

 


Semester Hour Requirements for the Basic Science Courses

The Board of Trustees has not established any minimum hour requirement for the required basic science courses. A minimum of 62 semester hours of college credit must be completed; within the 62 hours, a minimum of one course must be completed in each of the following areas: anatomy and physiology, chemistry, microbiology, physics, and mathematics.

The reason semester hour requirements were not established for the basic science courses is because of the lack of uniformity in semester hours (or quarter hours) awarded for similar courses by various colleges or universities across the country. For example, some colleges combine anatomy and physiology, and some colleges offer the two courses separately. Semester hours are awarded by some colleges, while others award credit in quarter hours. Completion of the courses themselves is more important than the number of hours awarded for the required courses.

The NBRC suggests students complete more than the minimum one course in mathematics and the basic sciences, because the more knowledge accumulated in these areas, the better the chance for success on the examinations associated with the RRT. No laboratory is required for the basic science courses, if the college or university offers the courses for credit without a laboratory requirement. Many colleges will not offer chemistry, physics, microbiology, etc., without a laboratory portion of the course.


Transcript Requirements

  1. Applicant who has held a valid CRT credential for a minimum of four years: Official transcripts must be submitted at the time of application under this provision. A minimum of one course in anatomy and physiology, chemistry, microbiology, mathematics, and physics must appear, by name, on the official transcripts. It must be apparent from the transcript that these courses have been completed. If any of the courses do not appear on the transcripts, by these names, the applicant must obtain a course description from the college catalogue for any course(s) in question and submit each course description(s) to the Admission Committee, in care of the NBRC, for review and final determination.
  2. Applicant who has held a valid CRT for a minimum of two years and have a baccalaureate degree in an area other than in respiratory therapy:
    1. Proof of completion of a baccalaureate degree must be submitted in the form of either official college transcripts or a notarized copy of your baccalaureate degree. Official transcripts verifying completion of the basic sciences and mathematics must also be submitted at the time of application.
    2. A minimum of one course in anatomy and physiology, chemistry, microbiology, physics, and mathematics must appear, by name, on the official transcript. It must be apparent from the transcript that these courses have been completed. If any of the courses do not appear on the transcript by these names the applicant must obtain a course description from the college catalogue. For any course(s) in question, submit course description(s) to the Admission Committee, in care of the NBRC, for final determination.

College Level Examination Program (CLEP)

Courses challenged through the College Level Examination Program (CLEP) will be accepted toward the 62 semester hours and basic science courses required, provided transferable college credit is awarded by an accredited college or university for each course completed by CLEP examination. The courses attempted through the CLEP program and the credit awarded must be recorded on an official transcript.


Courses Completed at Foreign Colleges or Universities

Courses taken at a foreign college or university do not satisfy the NBRC’s requirement of 62 semester hours of college credit. Foreign programs are not “accredited by their regional association or its equivalent." Persons who attended a foreign college should contact an accredited college to have transfer credit awarded for the training they have received. The NBRC will accept transfer credit for foreign courses if an accredited United States college or university is willing to award transfer credit. A letter sealed by the Registrar indicating the courses and hours for which transfer credit is awarded may be accepted in lieu of official college transcripts.


Training Completed at Hospital-Based Nursing or other Health-Related Programs

If you completed courses at a hospital-based nursing or other educational program not accredited by its regional association or its equivalent, the course work will not be accepted unless transfer credit for the courses is awarded from an accredited college or university. A letter sealed by the Registrar indicating the courses and hours for which transfer credit is awarded may be accepted.


Course Descriptions for the Required Basic Science and Mathematics Courses

The NBRC Admissions Committee has developed course outlines for the basic science and mathematics courses required under this provision. The course outlines recommend the content areas which should be covered in each of the basic sciences. These course descriptions are intended for those who have not yet completed some or all of the courses, and who require guidance in course selection. The course outlines can be obtained by writing the Executive Office.

RRT Credential FAQs

    • ​What changes were made to the RRT Examination program in 2015?

    ​Candidates become eligible to take the Clinical Simulation Examination by achieving the high cut score on the Therapist Multiple-Choice Examination. The passing point associated with RRT eligibility is higher than the passing point associated with the CRT credential.

    Elements of the RRT program, which includes elements of the CRT program, change as summarized in the following table:

    RRT Program Elements Number
    Currently Starting in 2015
    Hours of testing time 9
    Entry Level CRT=3
    Written RRT=2
    Clinical Simulation=4
    7
    Therapist Multiple-Choice=3
    Clinical Simulation=4
    Examinations 3
    Entry Level CRT
    Written RRT
    Clinical Simulation

    Therapist Multiple-Choice
    Clinical Simulation
    Testing sessions for a candidate who passes on the first attempt 3
    Entry Level CRT
    Written RRT
    Clinical Simulation
    2
    Therapist Multiple-Choice
    Clinical Simulation
    Sets of test scores 4
    Entry Level CRT
    Written RRT
    Clinical Simulation IG
    Clinical Simulation DM
    2
    Therapist Multiple-Choice
    Clinical Simulation
    Passing points 4
    Entry Level CRT=1
    Written RRT=1
    Clinical Simulation=2
    3
    Therapist Multiple-Choice=2
    Clinical Simulation=1
    Multiple-choice items to assess competencies broadly 240
    Entry Level CRT=140
    Written RRT=100
    140
    Therapist Multiple-Choice =140
    Patient management problems to assess competencies deeply 10 20
    Typical length of a patient management problem 10 (8-12) 5 (4-6)

    Starting in January of 2015, each therapist who achieves the RRT credential by passing each requirement on his or her first attempt will experience one less examination and testing session, two less hours of testing time, two less sets of test scores, and one less passing point. Persons who move through the program requirements in this way will save the $190 fee that has been associated with the Written RRT Examination in the past.

    Candidates who choose to take the Clinical Simulation Examination will respond to 22 problems instead of 11 problems, but each problem will contain half the number of sections. Hence, candidates will continue to have 4 hours to respond to the problems within the Clinical Simulation Examination. Two of the 22 problems are being pretested for the future, which means that responses to 20 problems will count toward candidates’ scores.

If a candidate achieves the higher cut score, they will earn the CRT credential AND become eligible for the Clinical Simulation Examination (provided that those eligibility requirements are met and the candidate is eligible to earn the RRT credential).​

    The NBRC does not publish cut scores for any examination.  Candidates will receive information about their score after completing the examination.
    • What happens if I am subject to the RRT Three-Year Eligibility Time Limit, and I don't earn my RRT credential before the deadline?​

    Individuals who do not earn the RRT credential within the time limit will be required to retake and pass the Therapist Multiple-Choice Examination at the CRT cut score to regain eligibility, and any previous passing performance to earn the RRT credential shall be nullified. After regaining eligibility by taking and passing the Therapist Multiple-Choice Examination at the CRT cut score, the candidate will have another three years to earn the RRT credential. If the candidate achieves the higher cut score on the first attempt, they will receive an additional three years to pass the Clinical Simulation Examination to earn the RRT credential.​
    • Can I still apply via the CRT to Registry Provision?

    Applicants shall satisfy ONE of the following requirements:

    • Be a CRT for at least four years prior to applying for the Registry Examination. In addition, the applicants shall have at least 62 hours of college credit from a college or university accredited by its regional association or its equivalent. The 62 semester hours of college credit must include the following courses: anatomy and physiology, chemistry, microbiology, physics, and mathematics.
    • Be a CRT for at least two years prior to applying for the Registry Examination.  In addition, the applicant shall have earned a minimum of an associate degree from an accredited entry-level respiratory therapy education program.
    • Be a CRT for at least two years prior to applying for the Registry Examination.  In addition, the applicant shall have earned a baccalaureate degree in an area other than respiratory care and shall have at least 62 semester hours of college credit from a college or university accredited by its regional association or equivalent.  The 62 semester hours of college credit must include the following courses: anatomy and physiology, chemistry, mathematics, microbiology, and physics.
    • ​I have already passed one portion of the current RRT Examination. What do I do now?

    ​Any candidate who has already passed the Written Registry portion of the RRT Examination will be eligible for the Clinical Simulation Examination. Candidates who have passed the Clinical Simulation Examination but not the Written Registry Examination will need to take the Therapist Multiple-Choice Examination and pass at the higher cut score to earn the RRT credential.​

    • ​I passed the Therapist Multiple-Choice Examination at the higher cut score, but am not eligible for the RRT. What do I do now?​

    ​Candidates who achieve the higher cut score on the Therapist Multiple-Choice Examination but are ineligible for the Clinical Simulation Examination at the time of testing, have five years from that date to use that passing score and meet the necessary requirements to become eligible for the Clinical Simulation Examination.​

    • ​I have earned my CRT but I have not yet attempted either portion of the RRT Examination. What do I do now?

    ​Practitioners who have earned the CRT credential and are eligible for the RRT will need to take the Therapist Multiple-Choice Examination and pass at the higher cut score to be able to continue on to take and pass the Clinical Simulation Examination to earn the RRT credential.

    • ​Does passing the Therapist Multiple-Choice Examination at the higher cut score automatically mean I’m eligible for the Clinical Simulation Examination?​

    ​No. All Candidates must meet the eligibility requirements, regardless of examination scores.​

    • ​​If I currently hold the CRT credential and score below the lower cut on the Therapist Multiple-Choice Examination, will I lose my CRT credential?

    ​No. You can retake the Therapist Multiple-Choice Examination as many times as necessary to regain RRT eligibility or to become eligible for the Clinical Simulation Examination without impacting the status of your current CRT credential.​

    • ​How will the examination changes affect the Continuing Competency Program?​

    ​All credentials earned on or after July 1, 2002 are subject to recertification. The NBRC strongly supports continued competency for the practitioners it certifies by requiring recertification every five years. Practitioners that earn the CRT and RRT credentials after 2015 will still be required to demonstrate their continued competence through the NBRC's Continuing Competency Program (CCP). Practitioners can also retake and pass the respective examination for the highest credential held that is subject to the CCP. If that credential is the RRT credential, individuals will need to retake and pass the Therapist Multiple-Choice Examination at the higher cut score and then retake and pass the Clinical Simulation Examination to recertify their RRT credential.​
