Helping Career Changers Map Respiratory Therapy Prerequisites- An advisor’s roadmap for adult learners moving into respiratory care– a growing share of respiratory therapy applicants are career changers—adults who already hold a degree or have worked in another field and are now moving into respiratory care. They bring maturity, prior coursework, and often real healthcare exposure. But their prerequisite map looks different from a traditional first-time student’s, and the difference is easy to miss: the issue is rarely whether they can do the science—it’s whether the credits they already earned still count.
This hub walks advisors and career changers through every requirement, then layers on the considerations unique to adult learners: course recency, transfer credit, GPA, and second-degree pathways. A transcript-mapping worksheet is included to turn an advising conversation into a concrete plan. For the at-a-glance version, see our Respiratory Therapy Prerequisite Checklist: https://www.prereqcourses.com/respiratory-therapy-prerequisite-checklist/
Every prerequisite exists to prepare a student for a regulated pathway, so it helps to map backward from the credential:
One timing note worth sharing with applicants: beginning January 1, 2027, the NBRC moves to a single Respiratory Therapy (RT) Examination (a lower cut score earns the CRT, a higher one the RRT), and the older “CRT-to-Registry” route is eliminated at the end of 2026. It doesn’t change the prerequisite list, but it reinforces that graduating from a CoARC-accredited program—which starts with prerequisites—is the only reliable path. Career-wise the field remains attractive: the U.S. Bureau of Labor Statistics projects 12% growth from 2024 to 2034 and a 2024 median wage near $80,450.

Requirements vary by program, but the courses below appear on the vast majority of CoARC program prerequisite lists. Most programs require a grade of C or better in each and a prerequisite GPA in the 2.5–3.0 range.
| Course | Why it matters / notes | Typical status |
|---|---|---|
| Anatomy & Physiology I | With lab. Foundation for cardiopulmonary anatomy. | Required |
| Anatomy & Physiology II | With lab. Respiratory, cardiovascular & renal systems. | Required |
| Microbiology | Often with lab. Infection control & pathogens. | Required |
| General/Intro Chemistry | With lab. Gas laws, acid-base balance. | Required |
| College Algebra (or higher) | Math foundation for dosing & calculations. | Required |
| English Composition | Written communication; often two courses. | Required |
| Speech / Communication | Verbal communication for patient care. | Common |
| General Psychology | Some programs accept developmental/lifespan. | Common |
| Medical Terminology | Frequently required or strongly preferred. | Common |
| Statistics | Required by many bachelor’s-entry programs. | Program-specific |
| Physics | Required by select bachelor’s-entry programs. | Program-specific |
| CPR / BLS certification | Healthcare-provider level, before enrollment. | Program-specific |
1. Course recency is the #1 issue
Many programs require science prerequisites—especially Anatomy & Physiology—to be completed within the last 5–7 years. A career changer who took A&P a decade ago for an unrelated degree will usually need to retake it, even with an A on the old transcript. General-education courses (English, math, psychology) typically do not expire. Always check each target program’s recency window before assuming old science credits transfer.
2. A prior degree can work in their favor
Career changers who already hold a bachelor’s degree have usually satisfied the general-education portion permanently. Some bachelor’s-entry RT programs offer accelerated or second-degree tracks that waive general education and focus on the science prerequisites plus the professional core. That can shorten the runway considerably—if the science credits are current.
3. GPA is often weighted, not just totaled
An old, lukewarm cumulative GPA worries many adult learners. Reassure them: programs frequently weight a prerequisite or science GPA, so strong recent grades in A&P, microbiology, and chemistry can carry significant weight. Some institutions also offer academic-renewal or grade-replacement policies—worth checking case by case.
4. Prerequisites have to fit around a job
Most career changers are working while they prepare. The scheduling bottleneck is usually a single course offered only in a fixed semester. Self-paced, online, accredited prerequisites remove that bottleneck and let students start and finish on their own calendar—the practical reason PrereqCourses.com exists: https://www.prereqcourses.com/
| Advisor tipBefore celebrating “already done” credits, run them through two filters: is the course within the program’s recency window, and did it transfer from a regionally accredited institution? Those two checks resolve most career-changer surprises. |

My A&P is 12 years old—does it count?
Usually not. Most programs require science prerequisites within 5–7 years, so plan to retake A&P even with strong original grades.
I already have a bachelor’s. Do I redo general education?
Generally no. A prior bachelor’s typically satisfies general education, and some programs offer accelerated second-degree tracks focused on the sciences and professional core.
My old GPA was weak. Am I out of the running?
Often not. Programs frequently weight a prerequisite/science GPA, so strong recent grades can offset an old cumulative number.
Can I keep working while I complete prerequisites?
Yes—self-paced, online, accredited prerequisites are designed to fit around a job and avoid fixed-semester bottlenecks.
