Step 1: Complete Your Degree in Respiratory Care

Professor Bill Galvin helps respiratory care students gain practical experienceThe first step in how to become a repiratory therapist is to complete a degree in respiratory care. To provide the best career opportunities, you should consider successfully completing the coursework required in a bachelor’s degree program in respiratory care. The bachelor’s degree curriculum generally includes coursework in clinical respiratory care, procedures, pharmacology, pathophysiology, mechanical ventilation and advanced respiratory theory.

Many programs require a competency assessment that demonstrates the attainment of skills and characteristics required for success in the respiratory care field. In addition, you will be required to complete clinical hours to acquire practical experience in this important medical field. 

Selecting a university program that has been accredited by the Commission on Accreditation of Respiratory Care will ensure the widest range of opportunities for you once you've completed  your respiratory therapist education. After graduation, respiratory therapists are qualified to work as bedside clinicians, patient educators and advocates, pulmonary rehabilitation specialists, neonatal/pediatric/adult critical care specialists and in management positions in hospitals and alternative care sites. 

Keep in mind that continuing education is often required to ensure the ongoing competency and quality of care for patients seeking treatment for breathing issues in the medical environment.

Step 2: Pass the Credentialing Examinations

Becoming a Certified Respiratory Therapist is usually the next step on your journey in how to become a respiratory therapist. The National Board for Respiratory Care (NBRC) is responsible for administering the examination required to achieve this certification. This multiple-choice test measures your general knowledge and offers pathways to entry-level and advanced-level credentialing:

  • You will first take the NBRC Therapist Multiple Choice Examination, and upon passing at the lower cut score level, will be awarded the entry-level Certified Respiratory Therapist (CRT) credential.
  • Passing the Multiple Choice Examination at the upper cut score level will allow you to sit the Clinical Simulation Examination.
  • After successfully passing the Clinical Simulation Examination, you will be awarded the Registered Respiratory Therapist (RRT) credential, which is the highest level credential of professional practice in this field.

While each of the above credentials can be used to demonstrate eligibility for licensure, the Registered Respiratory Therapist credential is clearly required for higher-level positions in the medical field.

Step 3: Apply for and Obtain a State License

Every state in the U.S. except for Alaska requires licensure for respiratory care practitioners. Students must have completed at least an associate degree to qualify for licensure in these 49 states. Most states require background checks for licensure applicants; some also offer trainee licenses for students in an accredited respiratory care program.

How Long Does It Take to Become a Respiratory Therapist?

The process of how to become a respiratory therapist takes a minimum of two years if you obtain your associates degree. However, many employers favor candidates who have a bachelor’s degree in the field, which takes about 4 years to complete. 

Hands-on clinical experience is also required to become a licensed respiratory therapist. After completing all respiratory therapist education requirements, including laboratory, simulation and clinical experiences in the hospitals, aspiring therapists must also pass a credentialing examination and acquire a license to practice in their home state.

So just how long does it take to be a respiratory therapist? The entire process may take up to four years from start to finish, including earning your Bachelor of Health Science in Respiratory Care degree and becoming licensed. Respiratory therapy is a rewarding career with a high demand in the healthcare field.
