How to Become a Respiratory Therapist: Complete Step-by-Step Guide
Becoming a respiratory therapist (RT) is one of the fastest paths into a credentialed clinical hospital role. Most graduates are working bedside within two and a half years of starting school, and the field offers strong wage growth as you specialize in adult critical care, neonatal/pediatric, or sleep medicine. This guide walks through every step from program selection to your first hospital ID badge, with the latest data from the U.S. Bureau of Labor Statistics and the National Board for Respiratory Care (NBRC).
Education Requirements
Every U.S. state requires respiratory therapists to graduate from a program accredited by the Commission on Accreditation for Respiratory Care (CoARC). The minimum is an Associate of Applied Science (AAS), which typically takes about 24 months of full-time study after prerequisites. Bachelor of Science programs add 12–24 months and are increasingly preferred by hospitals hiring into ICU, NICU, and leadership tracks. Coursework includes cardiopulmonary anatomy and physiology, mechanical ventilation, pharmacology, blood gas analysis, and several hundred hours of supervised clinical rotations across emergency, ICU, neonatal, and general floor settings.
Choosing a CoARC-Accredited Program
Look up programs on the CoARC searchable directory and prioritize three signals: the three-year average TMC pass rate (target 80%+), credentialing success rate (the share of graduates who earn the RRT, not just CRT), and on-time graduation rate. Community college programs run roughly $8,000–$25,000 in tuition; university BS programs run $30,000–$80,000+. Strong clinical site networks matter as much as price—rotations at a Level I trauma center and a Level III/IV NICU give you both the broadest skill set and the strongest hiring leverage.
The NBRC Credentialing Exams
After graduation you sit for the Therapist Multiple-Choice (TMC) Examination. Earning the lower cut score awards the Certified Respiratory Therapist (CRT) credential; earning the higher cut score qualifies you to take the Clinical Simulation Examination (CSE), which is required for the Registered Respiratory Therapist (RRT) credential. Most hospitals now hire only RRT-eligible or RRT-credentialed candidates, so plan to clear both within six months of graduating. Our CRT vs RRT credential guide covers exam content, scheduling strategy, and study resources in depth.
State Licensure
Forty-nine states plus D.C. require state licensure to practice respiratory care; Alaska is the lone exception. Licensure typically requires the CRT or RRT credential, a state application, a background check, and—in some states—a jurisprudence exam. Renewal cycles range from one to three years and require continuing education credits. Confirm your state’s specific rules before applying for jobs across state lines, and check whether your target employer participates in license reciprocity programs.
Landing Your First RT Job
About 80% of respiratory therapists work in hospitals, with the remainder in skilled nursing facilities, home healthcare, sleep labs, and physician offices. New graduates have the most options applying to teaching hospitals and large community health systems, both of which run structured RT residencies that rotate you through ICU, ED, NICU, and pulmonary rehab during your first year. Starting wages typically fall between the 10th and 25th percentile of the BLS distribution—see our entry-level RT salary page for current figures by state.
Continuing Education and Specialization
After 1–2 years bedside, most RTs add a specialty credential to access higher pay bands. The Adult Critical Care Specialist (ACCS), Neonatal/Pediatric Specialist (NPS), Sleep Disorders Specialist (SDS), and Asthma Educator (AE-C) are the four most lucrative. Each adds roughly $3,000–$10,000 to base annual pay in most markets and unlocks shift differentials at large academic centers. Our respiratory therapist specializations guide details which credentials produce the strongest ROI.
Total Timeline and ROI
From the first day of an associate-degree program to your first paycheck, the typical path takes 27–30 months. With a national median wage above $80,000 and total program costs often under $25,000 at community colleges, most graduates recoup their investment within the first year of practice. RTs who graduate into high-paying states like California, Nevada, and Massachusetts can earn six figures within three to five years, particularly with an RRT plus one specialty credential.
Common Application Mistakes
Three patterns derail otherwise strong RT program applications. First, choosing a non-CoARC program because it markets itself as faster — graduates of unaccredited programs cannot sit for the NBRC exams regardless of clinical hours completed. Second, underestimating the science prerequisites — most CoARC programs require A&P I/II, microbiology, college algebra, and chemistry with a minimum 2.7-3.0 GPA, and competitive applicants present 3.5+ in these courses. Third, skipping clinical observation — many programs require or prefer 8-16 hours of documented RT shadowing before applying, and applicants who skip this step are often ranked below those who completed it.
Bachelor's vs Associate Degree Decision
The associate degree is sufficient for licensure and entry-level practice. The bachelor's adds 12-24 months and $20,000-$60,000 in tuition but improves access to ICU, NICU, leadership, and academic positions. For candidates planning to stay bedside their entire career, the associate is the more cost-effective path. For candidates targeting clinical specialist, department director, or future graduate-school options (master's, anesthesia, perfusion), the bachelor's pays back through career flexibility. A common middle path: complete the associate, work as RRT for 1-2 years, then complete an online RT-to-BSRT bridge while working full-time. This minimizes opportunity cost while preserving the bachelor's option.
What to Expect During Training
The training pathway for respiratory therapist requires sustained focus and realistic time-budgeting. Most successful candidates plan their schedule around the program's clinical or practical hour requirements rather than treating it like standard college coursework. Build a study group early — students who form study groups in the first month of program have meaningfully higher completion rates than students who try to study alone. Track your progress against program-specific milestones rather than calendar weeks; some content is harder to internalize than others, and the timeline that works for one student rarely works for another.
Building Career Momentum in the First Year
The first 12 months after credentialing matter more than most new respiratory therapist realize. Pay raises, scope expansion, and access to better assignments all compound from the foundation built in year one. Specific habits that compound: documenting your case volume and outcomes from day one (useful for performance reviews and future job applications), building professional relationships with senior peers and supervisors (your strongest references will come from this period), and tracktracking the market wage in your metro quarterly so you know whether your pay is keeping pace. The candidates who treat year one as career-building rather than just training tend to outpace peers throughout their careers.
