Respiratory Therapy vs. Nursing vs. Rad Tech: Which Path- Three in-demand allied-health careers compared on schooling, prerequisites, pay, and day-to-day work — so you can choose with confidence.
If you want a hands-on healthcare career but are not sure which one, three paths come up again and again: respiratory therapy, nursing, and radiologic technology (“rad tech”). All three are stable, in-demand, and reachable in two to four years — and, importantly, they share much of the same foundational coursework. That last point is good news: you can begin preparing now, before you have fully decided, because the prerequisites overlap heavily.
This guide compares the three side by side — schooling, prerequisites, pay, job outlook, and the actual nature of the work — and points you to deeper resources for whichever path fits best. Figures below come from the U.S. Bureau of Labor Statistics (May 2024 data).
| The short versionRespiratory therapy focuses on breathing and the cardiopulmonary system, with an associate-degree entry point and strong projected growth. Nursing is the broadest role with the widest range of settings and the highest typical pay, usually built on a bachelor’s or associate degree. Rad tech centers on diagnostic imaging, with an associate-degree entry point. All three require overlapping science prerequisites — so starting those now keeps every option open. |
Here is the high-level comparison. Pay figures are national medians and vary widely by state, setting, and experience; outlook figures are 2024–34 projections.
| Factor | Respiratory Therapy | Nursing (RN) | Rad Tech |
|---|---|---|---|
| Typical entry education | Associate degree | Associate or bachelor’s | Associate degree |
| 2024 median pay | $80,450 | $93,600 | $77,660 |
| Projected growth (2024–34) | 12% (much faster) | 5% (faster) | 5% (faster) |
| Core focus | Breathing & cardiopulmonary care | Whole-patient care & coordination | Diagnostic imaging |
| Credential body | NBRC | State board / NCLEX | ARRT |

Whichever of these three you choose, you will need a similar foundation of general-education and science courses. That overlap is the single most useful thing to know if you are undecided, because it means you can start the common courses immediately and keep all three doors open while you make up your mind.
| Common prerequisite | Respiratory Therapy | Nursing | Rad Tech |
|---|---|---|---|
| Anatomy & Physiology I & II | Yes | Yes | Yes |
| English Composition | Yes | Yes | Yes |
| College Math / Statistics | Yes | Yes | Yes |
| Microbiology | Often | Yes | Sometimes |
| Chemistry | Sometimes | Often | Sometimes |
| Psychology | Often | Yes | Often |
Anatomy & Physiology is the universal anchor across all three — so it is the smartest course to start with while undecided.

You can complete many of these courses self-paced; browse the prerequisite courses here and confirm transferability with your target program before enrolling.
| Undecided? Start with Anatomy & PhysiologyBecause A&P I and II are required for respiratory therapy, nursing, and rad tech alike, completing them first is the lowest-risk move you can make. No matter which path you ultimately choose, the credit counts — and A&P is typically the longest and most heavily weighted prerequisite, so finishing it early removes the biggest bottleneck. |
Respiratory therapists care for patients with breathing and cardiopulmonary problems — from asthma and COPD to critically ill patients on ventilators. They run diagnostic tests, manage airway equipment, and respond in emergencies, working closely with physicians and nurses. Entry is typically through an associate degree, and graduates earn credentials through the National Board for Respiratory Care (NBRC), with programs accredited by the Commission on Accreditation for Respiratory Care (CoARC).
Of the three, respiratory therapy has the strongest projected growth — 12% from 2024 to 2034, much faster than average, per the Bureau of Labor Statistics. It is a strong fit if you want a focused clinical specialty rather than the breadth of nursing.

Registered nurses provide and coordinate patient care across nearly every healthcare setting, making nursing the most versatile of the three careers. RNs can enter through an associate degree or a bachelor’s (BSN), must pass the NCLEX-RN licensure exam, and have the clearest ladder to advanced, higher-paying roles such as nurse practitioner. Nursing carries the highest typical pay of the three — a $93,600 median in May 2024 — though projected growth (5%) is steadier than respiratory therapy’s.
Nursing suits people who want maximum flexibility in where and how they work, and who are comfortable with a broader scope of responsibility. The trade-off is a more competitive admissions landscape and, often, a longer or more demanding program.
Radiologic technologists perform diagnostic imaging — X-rays, and with further training CT or MRI — capturing the images physicians use to diagnose injury and disease. Entry is typically an associate degree, with certification through the American Registry of Radiologic Technologists (ARRT). Median pay was $77,660 in May 2024, with specialization in MRI or CT raising earning potential.
Rad tech fits people who enjoy working with technology and precise procedures, prefer scheduled diagnostic work over the unpredictability of bedside care, and want a clear technical specialty. Advancement often comes through adding imaging modalities rather than additional degrees.
Beyond the numbers, the right path comes down to the kind of work you want to do day to day. Ask yourself:
Whatever you decide, the prerequisites overlap — so you lose nothing by starting the shared sciences now.

Is respiratory therapy better than nursing?
Neither is universally better — they suit different goals. Respiratory therapy is a focused cardiopulmonary specialty with the fastest projected growth of the two, while nursing is broader, pays more on average, and offers more settings and advancement paths. The right choice depends on whether you prefer a specialty or maximum flexibility.
Which pays more: respiratory therapy, nursing, or rad tech?
Based on May 2024 BLS data, registered nurses had the highest median pay at $93,600, followed by respiratory therapists at $80,450 and radiologic technologists at $77,660. Actual pay varies widely by state, setting, experience, and specialization.
Do respiratory therapy, nursing, and rad tech share prerequisites?
Yes. All three typically require Anatomy & Physiology I and II, English composition, and college math, with microbiology, chemistry, and psychology required by many programs. Because the foundation overlaps, you can start the shared sciences before deciding which path to pursue.
Which has the best job outlook?
Respiratory therapy has the strongest projected growth of the three, at 12% from 2024 to 2034 (much faster than average), versus 5% for both nursing and rad tech. All three are projected to grow and remain in demand.
Can I switch paths after starting prerequisites?
Often yes, because the core science prerequisites overlap so heavily. Starting with Anatomy & Physiology keeps respiratory therapy, nursing, and rad tech all open. Confirm with your target programs how specific courses transfer before counting on them.
Which requires the least schooling?
All three are reachable through an associate degree. Nursing also offers a bachelor’s (BSN) path that increasingly aids advancement, while respiratory therapy and rad tech most commonly start at the associate level. Program length still varies, so check each program directly.
