How Long Does Respiratory Therapist School Take?

Respiratory therapist school takes two to four years, depending on whether you pursue an associate or bachelor’s degree. Most people complete an associate degree program in about two years and enter the workforce after passing national credentialing exams, which adds a few more months of study and testing. The full timeline from first class to first job typically falls between two and five years.

Associate Degree: The Most Common Path

Over 80% of entry-level respiratory therapy programs award an associate degree, making this the route most students take. These programs generally run two years of full-time study. Central Piedmont Community College’s program, for example, requires 74 credit hours completed across five semesters. That’s a fairly typical structure: four to five semesters of coursework and clinical rotations, with summers sometimes included to keep the timeline tight.

Some programs expect you to complete prerequisite courses before you apply, which can add time. Common prerequisites include human anatomy and physiology with lab, introductory chemistry with lab, microbiology with lab, introductory physics, and college-level algebra. If you’re starting from scratch with no college credits, budget an extra one to two semesters for these science and math courses. Students who already have general education credits from a previous degree or college experience can often jump straight into the professional program.

Bachelor’s Degree: Four Years Total

A bachelor’s degree in respiratory therapy typically takes four years. The structure splits roughly in half: two years of general education and prerequisite coursework, followed by two years of professional respiratory care courses and clinical training. Rowan University’s entry-level bachelor’s program, for instance, requires 120 total semester hours, with 60 hours of advanced study and clinical work completed after acceptance into the program.

The respiratory care profession has been pushing toward making a bachelor’s degree the standard for entry-level practice, similar to what nursing did years ago. Right now, an associate degree still qualifies you to sit for national exams and get licensed, but earning a bachelor’s degree can open doors to leadership roles, education positions, and higher starting pay. If you already hold an associate degree and are working as a therapist, bridge programs let you complete a bachelor’s in as little as 10 to 15 months online.

Clinical Rotations

Every respiratory therapy program includes hands-on clinical training in hospitals and healthcare facilities. Students typically log between 500 and 1,000 hours of clinical rotations during their program. These hours are built into the standard two-year or four-year timeline, not added on top of it.

The national accrediting body for respiratory care programs, CoARC, does not mandate a specific minimum number of clinical hours. Instead, it requires that each program ensure rotations are long enough and varied enough for students to develop all required competencies. Clinical hours increase as you move through the program, so your final semester will be much more heavily clinical than your first. You’ll rotate through areas like adult critical care, neonatal and pediatric care, pulmonary rehabilitation, and emergency departments.

Credentialing Exams After Graduation

Finishing school isn’t the final step. To practice, you need to pass national credentialing exams and obtain a state license. There are two levels of credential. The first is the Certified Respiratory Therapist (CRT), earned by passing a multiple-choice exam. The second and more widely expected credential is the Registered Respiratory Therapist (RRT), which requires passing both the multiple-choice exam at a higher cut score and a clinical simulation exam that tests decision-making in realistic patient scenarios.

You can apply for these exams as soon as you graduate from an accredited program, with no application deadlines or waiting periods. Once you apply, your eligibility stays active for one year. Most graduates spend a few weeks to a few months studying before sitting for each exam. If you’re focused and prepared, you can realistically complete both exams within two to three months of graduation.

State Licensure

Nearly every state requires respiratory therapists to hold a license or permit issued by a state board. You’ll apply after passing your national exams. Processing times vary by state and depend on the complexity of your application. Texas, for example, issues certificates on a weekly basis, so straightforward applications can be processed relatively quickly. Other states may take several weeks. Plan for a few weeks of administrative processing between passing your exams and receiving your official license to practice.

Graduate Programs for Advanced Practice

If you want to move into research, education, or advanced clinical roles after working as a therapist, master’s degree programs in respiratory care typically take about 24 months of full-time study. Rush University’s program requires a minimum of 92 credits completed over two years on campus, with a part-time option available for working therapists. These programs aren’t required to practice as a respiratory therapist, but they’re worth knowing about if you’re thinking long-term about your career trajectory.

Total Timeline at a Glance

  • Prerequisites (if needed): 6 to 12 months
  • Associate degree program: 2 years
  • Bachelor’s degree program: 4 years (or 10 to 15 months as a bridge after an associate degree)
  • Credentialing exams: 1 to 3 months after graduation
  • State licensure processing: 2 to 6 weeks

For most students starting with no prior college credits who choose the associate degree path, the realistic timeline from enrollment to working as a licensed respiratory therapist is about two and a half years. Students pursuing a bachelor’s degree should plan on four to four and a half years. Either way, the clinical training is woven into the program itself, so you won’t need extra time beyond your degree to gain hands-on experience.
