Nurse Practitioner vs Physician Assistant
Advanced Practice Providers (APPs) are an integral part of the healthcare team — and NPs and PAs often perform very similar jobs, sometimes the exact same one. But what exactly is the difference? This article compares their education and training, job role, physician collaboration, and salary.
Note: This guide compares master's-prepared NPs vs master's-prepared PAs. Alternative routes like direct-entry, RN-MSN bridge programs, and the Doctorate of Nursing Practice (DNP) are not covered here. Related reading: NP vs MD: Which One Is Better?
Education & Training
Both NPs and PAs are considered APPs, and both often work alongside physicians — which is where the confusion starts. Their training paths, however, differ in important ways.
Undergraduate Degree
PAs first earn a bachelor's degree in any field, but they must complete prerequisites for PA school. Future NPs typically earn a Bachelor of Science in Nursing (BSN). Both take about 4 years (some PA paths compress the bachelor's into ~3 years).
After Graduation
PAs should already be admitted to a PA program and move immediately into their master's. NPs first pass the NCLEX-RN and begin working as a bedside nurse. Some RNs go straight into NP studies, but most work anywhere from a year to 20+ years before pursuing their master's.
The PA / NP Programs
PAs complete a master's such as Physician Assistant Studies, Health Science, or Medical Science (MMSc). NPs complete a Master of Science in Nursing (MSN). The key distinction: PAs are trained as generalists and can work in essentially any setting with appropriate supervision, while NPs choose a specific patient population:
Program Structure
Most PA programs run about 2 full-time years (24–26 months): roughly a year of intensive didactic medical science (like a compressed first year of medical school), followed by clinical clerkships in pediatrics, OB/GYN, family practice, general surgery, and emergency medicine — totaling about 2,000 clinical hours.
NP programs offer full-time, part-time, and online options. They usually start with didactic material (advanced pathophysiology, pharmacology, and health assessment), then add clinicals while didactic continues — often 16 hours per week (two 8-hour days). Where you train depends on your specialty: FNPs rotate through primary care, women's health, and pediatric clinics; acute care NPs do most rotations in the hospital ICU. NPs complete an estimated 600–800 clinical hours by graduation.
Licensure
After graduation, PAs must pass the PANCE (Physician Assistant National Certifying Examination) to become certified. NPs pass their specialty board exam through the AANP or ANCC. Both then apply for state licensure and can practice as APPs once credentialed. Related reading: Nurse Practitioner: Steps After Graduation.
Job Role
The actual day-to-day role of an NP and a PA is very similar — if not identical — at almost any location and specialty. Both:
They both work in nearly every setting — outpatient primary care, specialty offices, inpatient hospitalist or ICU roles, the ED and urgent care, home health/hospice, surgery, and more.
One Difference: Surgery
NPs can become a first-assist, but it's much less common — they usually handle admissions and discharges for the surgical team rather than scrubbing in. PAs are more likely to scrub in and assist with surgery, which makes sense since NP programs generally don't include surgical rotations.
Collaboration & Supervision
This is where the main difference lies. NPs have full practice authority (FPA) in 23 states and counting. In FPA states, NPs may evaluate patients; diagnose; order and interpret tests; and initiate and manage treatments — including prescribing medications and controlled substances — under the exclusive licensure authority of the state board of nursing.
NPs in non-FPA states require varying degrees of physician collaboration depending on the state and setting, spelled out in a collaborative agreement covering practice protocols, documentation review, and prescriptive authority. In practice this often means occasional chart reviews and availability for consultation by phone or text — not an on-site physician.
PAs are always required to work under the direction and supervision of a physician or group of physicians. State laws shape the specifics — prescriptive authority, prescription co-signatures, collaborative agreements, and scope of practice. In practice this may involve consulting the physician on complicated cases and co-signing charts and controlled-substance prescriptions, though the physician typically just needs to be reachable, not on-site.
For both NPs and PAs, states vary on who can legally sign death certificates, POLST forms, or order physical therapy. As a general rule, the NP career offers more opportunity for autonomy — but both are competent, valued members of the healthcare team working within their respective scopes.
Salary
Both make similar salaries, and many facilities pay their counterparts the same. On national data, NPs average $117,292 and PAs average $107,179 (Glassdoor). Keep in mind this is national data — the fact that some NPs have the autonomy to open their own practices typically means higher revenue, which skews the national NP figure upward.
And that's the difference between PAs and NPs. They're different paths, but they perform essentially the same job role with similar career outlooks. Some physicians and hospitals prefer one over the other (I've seen it go both ways), but most employers recognize the value of both as integral members of the team.
