The Certified Respiratory Therapist Exam (CRT) is an exam for entry-level respiratory therapists. Successful performance on the exam leads to the CRT designation, which is a voluntary certification credential.

The certification is administered by the National Board for Respiratory Care.

The CRT test is comprised of 160 multiple-choice questions that cover clinical data, therapeutic procedures and equipment. Twenty questions are pretest questions. Test questions will focus on the ability of the test taker to recall, apply and analyze information. Three hours are allotted for completion of the exam.

Exam candidates must be 18 years old and either have an associate degree in respiratory therapy from an accredited institution or be enrolled in an accredited bachelor’s degree program in respiratory therapy. Candidates meeting the latter requirement will need to provide a certificate of completion from their college or university that indicates the successful completion of coursework in advanced science and respiratory therapy classes.

CRT exams are offered via computer at AMP Testing Centers. More than 170 test centers nationwide offer the CRT exam. Test appointments can be scheduled Monday through Saturday from 9:00 a.m. to 1:30 p.m. An appointment to test is required before a candidate will be able to take the exam.

Following completion of the exam, test takers will receive a score report from the proctor. The report will include a scaled score and indicate if the test taker passed or failed the exam. The minimum passing score on the CRT is 75. Within a month following the exam, candidates who passed the exam will receive a certificate and wallet card and may begin using the CRT designation with their name.


The National Board for Respiratory Care recommends that CRT test candidates become familiar with the computerized test model and suggests taking pretests to prepare.
