Respiratory therapists (RTs) play a critical role in modern healthcare, supporting patients with breathing disorders and complex cardiopulmonary conditions. As medical technology continues to advance and the population ages, the demand for bachelor’s-prepared RTs will continue to rise. Currently, fewer than 10% of respiratory therapists in the United States hold a Bachelor of Science in Respiratory Care, highlighting a growing opportunity for those who pursue advanced education.
Texas State University’s online Registered Respiratory Therapist to Bachelor of Science in Respiratory Care (RRT to BSRC) program — the largest respiratory care program in the country — equips students with professional development in critical care, education, research and leadership. The program’s flexibility enables therapists to continue working while completing their studies online.
Respiratory Therapy Prerequisites and Coursework
Becoming a respiratory therapist requires a strong foundation in the sciences. Students typically begin with prerequisite courses in anatomy and physiology, biology, chemistry and microbiology. Some programs also require introductory psychology, statistics and communication courses. Many institutions expect applicants to complete clinical experience hours before admission, giving them firsthand exposure to patient care and respiratory therapy practices.
Core respiratory therapy coursework often includes cardiopulmonary assessment, mechanical ventilation, pharmacology and diagnostic testing. According to CareerExplorer, respiratory therapy education combines classroom instruction with supervised clinical training, ensuring graduates are prepared for both technical and patient-facing responsibilities.
RRT Certification Process and NBRC Exam Requirements
After completing an associate degree or entry-level program, aspiring respiratory therapists must meet the credentialing standards set by the National Board for Respiratory Care (NBRC). The process begins with the Therapist Multiple-Choice (TMC) exam.
The TMC exam determines eligibility for both the Certified Respiratory Therapist (CRT) and the Registered Respiratory Therapist (RRT) credentials. Candidates who achieve the higher cut score on the TMC exam may then proceed to the Clinical Simulation Examination (CSE) to earn the RRT credential.
Respiratory Therapy Licensure and Continuing Education Requirements
Every state in the U.S., except Alaska, requires respiratory therapists to hold a license. While requirements vary, most include proof of graduation from an accredited program, passing NBRC exams and completing an application with fees.
In some states, continuing education may also be required to maintain licensure. These requirements ensure practicing therapists stay up to date with advancements in respiratory care delivery and standards of practice.
Advancing RRT Careers With Bachelor’s Degree Completion
While entry-level practice is possible with an associate degree, earning a bachelor’s degree has become an important milestone for respiratory therapists seeking leadership roles or specialized positions. The online RRT to BSRC program at Texas State University provides a pathway for working professionals to complete their degree in a flexible format. Coursework emphasizes advanced clinical practice, research methods, and leadership training.
This program also supports accelerated degree completion, allowing motivated students to finish their studies more quickly while balancing work and family responsibilities. For therapists who want to expand their skills in areas such as critical care or education, completing their bachelor’s degree provides a competitive edge.
Career Outlook for Registered Respiratory Therapists
Respiratory therapy is a growing profession with strong job prospects. According to the U.S. Bureau of Labor Statistics, respiratory therapists in the United States earned a median annual salary of $80,450, with a projected 12% job growth from 2024 to 2034, much faster than the average for all occupations. This demand is driven by an aging population, the prevalence of chronic respiratory conditions and advances in life-saving medical technology.
Earning a bachelor’s degree in respiratory care is more than an academic milestone. It is a step toward professional growth, broader career opportunities and the ability to contribute to the advancement of patient care. For respiratory therapists ready to take the next step in their careers, completing a bachelor’s degree can open the door to new possibilities in 2025 and beyond.
