How To Become A Respiratory Therapist

This field requires individuals to have at least an associate degree in respiratory therapy from an accredited institution. Most programs require at least two-years of education.

A bachelor’s or master’s degree (which can take four years to complete) may be required by some employers. A four-year degree program in respiratory care can increase your career prospects and earning potential. 

Below are the recommended steps to becoming a certified respiratory therapist.

High School Diploma or GED

A high school diploma or GED is required.

Attend An Accredited Program

Most accredited programs are 2-4 years. Community colleges are a great choice, but it is important to make sure the program is approved by the Commission on Accreditation for Respiratory Care.


Once you complete a training program you can then sit for the NBRC exams. These exams allow you to become certified (CRT) or registered (RRT) as a therapist.


All states, except Alaska, require licensing.

Attend An Accredited Respiratory Therapy Program

The first step to become a registered respiratory therapist is to find a respiratory therapy education program, that is accredited by the Commission on Accreditation for Respiratory Care (CoARC).  These programs meet national standards set by the American Medial Association and prepare students for certification exams.

Once you select a school to attend you will complete a mix of classes and clinical experience.

Some of what you can expect during your education includes:

  • Respiratory system anatomy where you will learn how the respiratory system works. This includes how the lungs function and are structured to work with airways and other organs.
  • Respiratory diseases and illnesses that affect patients. You will be provided details on illnesses like chronic obstructive pulmonary disease (COPD), asthma, pneumonia, or respiratory infections.
  • Patient assessment so you can learn how to properly evaluate respiratory functions and conduct and read diagnostic tests.
  • Treatment modalities that are often used to treat patients. This part of the education may include learning about mechanical ventilation, physiotherapy, oxygen therapy, or bronchodilators.
  • Practice respiratory therapy techniques will allow you the opportunity to get the hands on experience you need to properly care for patients.

Respiratory Therapist Certifications

Once you complete your associate’s degree in respiratory care, you can then sit for exams that are offered by the National Board for Respiratory Care (NBRC). 

There are two exams available:

  • Therapist Multiple-Choice Exam (TMC)
  • Clinical Simulation Examination (CSE)

In order to take the CSE exam, you must pass the TMC exam with a high cut score. The CSE exam is required to become registered. 

Passing these exams can result in the following:

  • Certified Respiratory Therapist (CRT) – this is a required exam that will allow you to prove your skills and become certified. 
  • Registered Respiratory Therapist (RRT) – this is an optional exam that will certify you to work as a registered therapist which can result in higher wages and better job opportunities. 

You can also choose to become a respiratory specialist in a variety of areas and earn additional CRT and RRT credentials. 

  • Adult Critical Care Specialist (RRT-ACCS) 
  • Sleep Disorders Specialist (CRT-SDS)
  • Neonatal/Pediatric Specialist (RRT-NPS)
  • Certified Pulmonary Function Technologist (CPFT)
  • Registered Pulmonary Function Technologist (RPFT)

Radiation therapist is another option if you are feeling like respiratory is not your thing!

Respiratory therapists need licensure in every state (except for Alaska). 

Each state has its own licensing requirements, but most require passing one or more licensing exams after completing a formal program and obtaining certification from NBRC. 

You can get a list of contact information by state here. You can contact the board of respiratory care for your state to get more information on the specific requirements.
