The Arizona State Board of Respiratory Care Examiners licenses respiratory therapists. You can apply online using the page mentioned at the bottom of this article.
The first main requirement is to complete an approved respiratory program. A number of accredited schools have respiratory therapy or similar programs.
The second is to pass a licensing/certification exam. Based on the rules at the time of this post, the Board is accepting CRT and RRT exams.
The tests are administered by the National Board For Respiratory Care. CRT is the Certified Respiratory Therapist exam. As long as you meet other requirements, you would then be nationally certified. But you still have to apply to the Arizona Board to get a state license. RRT is the Registered Respiratory Therapist exam. As with CRT, this is a big step. But you still have to separately apply for a license with the Board. Find out more about these tests here.
CRT is the credential for entry-level respiratory therapists, while RRT is the advanced level. CRT is $190, while RRT is $190 for a written exam, and $200 for the clinical simulation.
Besides education and testing, you have to pass a background check to get your license. That includes submitting fingerprints.
The total fee for an Arizona respiratory care license is about $270. The includes the fingerprints, the application, and the license.
