PA vs NP: training, scope and pay compared

Both roles diagnose, treat and prescribe, and on a busy service you will often see a PA and an NP doing the same work side by side. The paths that get you there are different, and that difference shows up in how each profession is certified and regulated.

PAs go to a graduate program after a bachelor's degree. According to AAPA, PA programs run about 27 months (three academic years) and include more than 2,000 hours of clinical rotations. AAPA also describes the curriculum as modeled on medical school, with rotations that include family medicine, internal medicine, obstetrics and gynecology, pediatrics, general surgery, emergency medicine, and psychiatry. The point of that structure is breadth: you graduate as a generalist and learn your specialty on the job.

NPs start as registered nurses. AANP states that every NP completes a master's or doctoral program with advanced clinical training beyond their initial RN preparation. To become an NP you must be licensed as an RN, graduate from an accredited graduate NP program and pass a national NP board certification exam. NP programs are organized around a population focus, such as family, adult-gerontology, pediatrics or psychiatric mental health, so you pick your patient population before you graduate.

AAPA sums up the distinction in one line: PAs are trained to practice medicine, and NPs are trained in the advanced practice of nursing. Neither model is better in the abstract. The useful question is which one matches the experience you already have and the kind of career you want to build.

This is where the two professions diverge most clearly, and it affects your time and money every year you practice.

On the PA side, NCCPA describes certification as a professional requirement for licensure in all U.S. states. To sit for the PANCE you must graduate from an entry-level PA program accredited by ARC-PA, and after you pass you can use the PA-C mark as long as you keep your certification current. The 10-year cycle is five two-year blocks, and in each block you must earn and log 100 CME credits. Then you must pass the PANRE or PANRE-LA by the end of the 10th year of your certification maintenance cycle.

On the NP side, NPCB certification renews every 5 years. Its practice-based renewal option requires 1,000 hours as an NP in the population focus of your certification, plus continuing education, and the pharmacology credits must be advanced practice pharmacology that are completed within the 5-year certification period. ANCC certification is renewed every five years through continuing education and professional development.

The practical takeaway: NPCB renewal by practice hours is tied to working in your certified population. PA certification is generalist, so the same PA-C carries you from orthopedics to cardiology to the emergency department. If you are an NP thinking about moving to a different population, ask your certifying board and your state board of nursing what that move would require before you accept a job built around it.

Neither profession has one national scope of practice. Your state's practice act decides how much you can do without a physician agreement, and the rules are different for PAs and NPs in the same state.

For NPs, AANP sorts every state into three categories. In a full practice state, state law permits NPs to evaluate patients, diagnose, order and interpret tests, and initiate and manage treatment under the authority of the state board of nursing. In a reduced practice state, the law requires a career-long collaborative agreement with another provider or limits the setting of at least one element of practice. In a restricted practice state, the law requires career-long supervision, delegation or team management by another provider. As of June 2026, AANP counted 27 states plus Washington, DC and two U.S. territories that had removed the physician agreement requirement through full practice authority laws. Check the AANP State Practice Environment map for your state, because these laws change often.

For PAs, AAPA notes that most state laws require PAs to have an agreement with a specific physician in order to practice. AAPA's policy goal, which it calls Optimal Team Practice, is to remove the requirement that a PA be supervised by a specific provider while keeping team-based care that is decided at the practice level. According to AAPA, ten states have eliminated the legal requirement for a specific relationship between a PA and a physician: Delaware, Iowa, Maine, Montana, New Hampshire, North Dakota, South Dakota, Utah, Virginia, and Wyoming.

If you plan to move, also look at licensure portability. For PAs, see our guide to the PA Licensure Compact. If you are in Texas, our Texas PA license guide covers the state process.

The national pay gap is small at the middle of the range and wider at the top. These are cross-industry figures for every PA and NP the survey counted, so they mix specialties, settings and experience levels.

Three things to notice. First, at the 10th percentile NPs earn slightly more than PAs, so the entry point is roughly even. Second, the gap widens as you move up: at the 90th percentile PAs are $15,860 ahead. Third, OEWS wage estimates do not include nonproduction bonuses or employer costs of benefits such as health insurance and retirement contributions, so a sign-on bonus or a strong 401(k) match will not show up in these numbers.

The national gap is not a reason to choose one profession over the other. Specialty, setting, region and how you are paid (salary, hourly, or productivity) move your income far more than your credential does. To see the numbers for where you live, use the salary pages for physician assistants and nurse practitioners, including Texas PAs and Texas NPs.

If you are still deciding which path to train for, work through these questions honestly. Your answers usually point clearly in one direction.

• Are you already an RN? If you have a nursing license and bedside experience, the NP route builds on what you have. If you do not, the NP path means becoming an RN first.
• Do you want to move between specialties? PA training and certification are generalist. NP certification is tied to a population, and NPCB renewal counts practice hours in that population.
• Where do you want to live? Look up your target state on the AANP map and the AAPA state laws pages. Full practice authority for NPs and team practice laws for PAs differ state by state.
• Which patient population do you want? If you already know you want pediatrics, women's health or psychiatry, an NP population focus matches that. If you are unsure, PA breadth keeps more doors open.
• Which model of thinking fits you? The medical model centers on diagnosis and disease. The nursing model adds a strong emphasis on the whole patient, prevention and education. Both are valid ways to practice.
• What will recertification cost you in time? Compare 100 CME credits every two years plus a recertification exam every ten years with your NP board's five-year renewal requirements.

Most readers of this guide are not choosing a school. They are a PA or an NP comparing a job posted for "PA or NP" and wondering whether their credential changes the offer. A few questions to ask the employer:

1. Is the pay range the same for PAs and NPs in this role? If not, ask why.
2. Who is my supervising or collaborating physician, and what does the agreement require (chart review, co-signature, on-site time)?
3. Do my visits bill under my own NPI, and do they count toward my productivity the same way a physician's would?
4. If state law changes and the agreement requirement goes away, does my role change?

Then compare the offer against the percentile data for your state, not the national average. Our guides on negotiating a PA or NP job offer and the employment contract checklist walk through what to ask for and what to get in writing.
