Physical therapy school requires more years of education and a higher degree, but nursing is widely considered more physically and emotionally demanding as a career. The answer depends on whether you’re asking about the path to get in or the daily reality of the job, because the two professions split on difficulty in very different ways.
Education: PT Requires a Doctorate
This is the clearest difference between the two fields. To practice as a physical therapist, you need a Doctor of Physical Therapy (DPT) degree from an accredited program, which takes about three years of graduate school after completing a bachelor’s degree. That’s roughly seven years of post-secondary education before you can treat your first patient independently.
Nursing has a much lower entry point. You can become a registered nurse with an associate degree in nursing, which typically takes two years. A Bachelor of Science in Nursing (BSN) takes four years, and accelerated programs can compress it to as few as 16 months for people who already hold a bachelor’s degree in another field. Either way, you’re working years sooner than a PT graduate.
The financial gap reflects this. Federal student loan data shows that graduates of doctoral programs in rehabilitation and therapeutic professions (the category that includes DPT) carry an average of about $109,000 in federal student debt for professional degree programs. Graduate-level nursing programs average considerably less, around $52,000 for a master’s and $78,000 for a professional nursing degree. If you’re comparing a BSN (undergraduate-level debt) to a DPT, the gap is even wider.
Prerequisite Coursework
DPT programs require a heavy science foundation before you even apply. The standard prerequisites listed across programs include two semesters of anatomy and physiology, two semesters of biology, two semesters of chemistry, and two semesters of physics. That’s a significant load of lab sciences, and physics in particular sets PT apart from most other health professions.
Nursing programs also require anatomy, physiology, biology, and chemistry, but they generally don’t require physics or as many semesters of each subject. The prerequisite burden for PT school is closer to what you’d see for medical school applicants, which makes the admissions process longer and more demanding on the front end.
Licensing Exam Pass Rates
Both professions require passing a national licensing exam, and the pass rates offer a rough proxy for difficulty. The National Physical Therapy Examination (NPTE) has a first-time pass rate of 85% for graduates of U.S.-accredited programs in 2025. The NCLEX-RN, nursing’s licensing exam, historically has a first-time pass rate in a similar range, typically between 85% and 90% depending on the year. Neither exam is easy, but they’re comparable in terms of how many graduates clear them on the first try.
Clinical Training Demands
DPT students complete extensive hands-on training spread across all three years of their program. At UCSF, for example, students complete 34 weeks of full-time clinical experiences, starting with introductory clinical days in the first year and building to 10- and 12-week full-time rotations in the second and third years. These rotations require students to independently evaluate patients, design treatment plans, and progress those plans over time.
Nursing clinical rotations happen during the degree program as well, but the nature of the work differs. Nursing students rotate through multiple hospital units (medical-surgical, pediatrics, labor and delivery, intensive care) and learn to manage medications, monitor vital signs, respond to acute changes, and coordinate with physicians. The breadth of clinical settings in nursing is generally wider, while PT clinical training goes deeper into musculoskeletal assessment and rehabilitation.
Physical Toll on the Job
Both careers are physically demanding, but nursing has the harder numbers. Bureau of Labor Statistics data from 2016 shows that registered nurses experienced musculoskeletal disorders at a rate of 46 cases per 10,000 full-time workers, well above the rate of 29.4 for all occupations. Over half of all nursing injuries were sprains, strains, or tears, occurring at a rate of 53.1 per 10,000 workers. Back injuries alone affected nurses at nearly double the rate of the general workforce.
The primary culprit is patient handling. Two-thirds of all musculoskeletal injury cases among nurses were caused by direct contact with patients: lifting, repositioning, and transferring people who may be unconscious, combative, or unable to bear their own weight. Physical therapists also lift and support patients, but their patients are typically more mobile and actively participating in the movement. Nurses often handle the heaviest, least cooperative lifting scenarios, particularly in hospital settings.
Emotional and Mental Demands
Nursing carries a heavier emotional burden for most people. Nurses routinely deal with patient death, family grief, and high-acuity emergencies. They work 12-hour shifts, often overnight, and manage multiple patients simultaneously in fast-paced environments. Burnout among nurses runs at roughly 11% overall, but it climbs dramatically in high-stress settings: 35% in emergency departments and up to 47% in intensive care units. Emotional exhaustion affects about 25% of nurses across settings.
Physical therapists report lower overall burnout, around 8% in pooled estimates, though emotional exhaustion still affects about 27% of PTs. The stressors are different. PT burnout tends to stem from high caseloads, productivity requirements (many outpatient clinics expect therapists to see patients back-to-back with little documentation time), and the frustration of working with patients whose progress is slow or limited. But PTs rarely face life-or-death situations, and their patients are generally getting better rather than declining.
Staff shortages, high workloads, and poor leadership are the common organizational factors driving burnout in both professions.
Autonomy and Decision-Making
Physical therapists function as independent practitioners in most states. They can evaluate patients, diagnose movement disorders, and design treatment plans without a physician’s referral. This means PTs carry significant clinical decision-making responsibility from day one.
Registered nurses work under the direction of physicians or nurse practitioners. They make critical real-time decisions about patient care, but they don’t independently diagnose or prescribe. The cognitive load is different: nurses need to monitor and synthesize information across multiple patients at once, catching subtle changes that signal a patient is deteriorating. PTs need to deeply assess one patient at a time and build a long-term rehabilitation plan. Both require strong clinical reasoning, just applied in different ways.
Which Is “Harder” Depends on What You Mean
If you’re asking which is harder to get into and complete academically, physical therapy wins. It requires more years of school, more prerequisite science courses, a doctoral degree, and more student debt. The barrier to entry is objectively higher.
If you’re asking which is harder to sustain as a career, nursing presents more challenges for most people. The physical injury rates are higher, the emotional exposure is more intense, the shift work is more disruptive, and burnout in high-acuity settings is significantly worse. Physical therapy is physically tiring, but the work environment is generally more predictable and the emotional toll is lower.
People who thrive in fast-paced, high-stakes environments with variety may find nursing energizing rather than draining. People who prefer focused, one-on-one patient relationships and longer-term outcomes tend to gravitate toward PT. Neither path is easy, and both reward people who are genuinely drawn to the work rather than just comparing difficulty levels.
