Respiratory therapists must have a minimum of an associate degree from an accredited respiratory therapy education program by the Commission on Accreditation of Respiratory Care

Most decide to earn a bachelor’s degree because it provides greater job opportunities and career opportunities. Bachelor’s programs should include specific coursework in clinical respiratory care, procedures, pharmacology, pathophysiology, mechanical ventilation, and advanced respiratory theory.

Step 2: Become Certified

  • Registered Respiratory Therapist (RRT)

Certified Respiratory Therapist (CRT)

According to the National Board for Respiratory Care, individuals who earn the CRT credential have obtained sufficient clinical skills through the education program from which they graduated and sufficient knowledge mastery to provide competent respiratory care at entry into practice. 

Most CRTs are employed in medical-practice settings such as inpatient hospitals; some CRTs are employed in outpatient clinics, free-standing diagnostic centers, and device manufacturing. 

In order to become a CRT, you’ll need to take and pass a certification exam.

Registered Respiratory Therapist (RRT)

CTRs and RRTs take the same exam, but RRTs have demonstrated a higher level of proficiency by achieving a higher score and through additional evaluation of knowledge about facilitating the care of patients with a variety of needs.
