Nurse practitioners (NPs) are advanced practice registered nurses who diagnose and treat patients, order and interpret tests, and prescribe medication — in many settings they serve as patients’ primary care providers. It is one of the most in-demand roles in American healthcare, and one of the most common goals nurses set after earning their RN license. The path is longer than becoming an RN, but it is clearly mapped: RN license first, then a graduate degree, national certification, and state APRN licensure. This guide breaks down the requirements, the timeline, the specialty choices, and the costs so you can plan each step.
Step 1: Become a Registered Nurse With a BSN
Every nurse practitioner starts as an RN. Graduate NP programs require an active, unencumbered RN license and a Bachelor of Science in Nursing. If you are starting from zero, follow the standard route laid out in our guide on how to become a registered nurse: earn your BSN, pass the NCLEX-RN, and get licensed in your state. If you currently hold an ADN, you will need to complete a BSN first — RN-to-BSN bridge programs are built for exactly that, and many nurses then continue into RN-to-MSN programs that combine both steps.
Most NP programs also expect clinical experience as an RN. Requirements range from a preference for one year of experience to a firm minimum in a relevant setting — for example, acute care experience for acute care NP tracks, or psychiatric experience for PMHNP programs. Competitive applicants usually bring at least one to two years of solid bedside practice.
Step 2: Earn a Graduate Nursing Degree — MSN or DNP
NP education happens at the graduate level, through one of two degrees:
- Master of Science in Nursing (MSN): the traditional NP degree, typically about two years of full-time study or two to three years part-time.
- Doctor of Nursing Practice (DNP): a practice-focused doctorate, typically three to four years after the BSN (BSN-to-DNP programs), adding coursework in leadership, quality improvement, and systems-level practice.
Both degrees lead to the same certification exams and the same NP license. National nursing organizations have long encouraged the DNP as the standard for advanced practice, and some employers and states show a growing preference for it, but the MSN remains a fully valid and widely used entry route. Programs accredited by CCNE or ACEN combine advanced coursework — advanced pathophysiology, pharmacology, and health assessment — with extensive supervised clinical training in your chosen specialty. Accredited NP programs include a minimum of 500 faculty-supervised clinical hours, and many programs require considerably more.
Step 3: Choose Your NP Specialty
NPs certify in a specific patient population, and you choose your focus when you apply to graduate school. The major population foci are:
- Family (FNP): care across the lifespan; the most common and flexible specialty
- Adult-Gerontology (AGNP): adolescents through older adults, in primary care or acute care
- Pediatric (PNP): infants, children, and adolescents
- Psychiatric-Mental Health (PMHNP): mental health across the lifespan
- Women’s Health (WHNP) and Neonatal (NNP): focused specialty populations
Choose based on the patients you want to serve and the settings you want to work in — your certification, and the jobs you qualify for, will match this population.
Step 4: Pass National Certification
After graduating, you must pass a national certification exam in your specialty before any state will license you as an NP. The main certifying bodies are the American Nurses Credentialing Center (ANCC) and the American Academy of Nurse Practitioners Certification Board (AANPCB), which offers the widely used FNP certification. Exams are computer-based, a few hundred questions in length, and test advanced clinical knowledge and decision-making for your population focus. Your graduate program should report its graduates’ pass rates — a useful quality check when comparing schools.
Step 5: Get Your State APRN License
With certification in hand, you apply to your state board of nursing for licensure as an Advanced Practice Registered Nurse (APRN) with NP recognition. Practice authority varies significantly by state: some states grant NPs full practice authority to evaluate, diagnose, and prescribe independently, while others require collaborative or supervisory agreements with a physician, especially early in practice. Federal law also requires a DEA registration if you will prescribe controlled substances. Because rules differ state by state, check your board of nursing’s requirements before choosing where to study and work.
How Long Does It Take to Become a Nurse Practitioner?
- BSN: about 4 years (or 2-3 years for the ADN-plus-bridge route)
- RN experience: typically 1-2 years recommended before or alongside graduate study
- MSN: about 2 years full-time (2-3 years part-time)
- DNP: about 3-4 years in a BSN-to-DNP program
- Total: realistically 6 to 8 years from starting nursing school to NP practice
Already a BSN nurse? Your remaining path is the graduate degree plus certification. Not yet a BSN holder? Our RN to BSN guide explains the fastest bridge options, and this overview of RN to BSN programs, costs and timelines will help you budget the first leg of the journey.
What Does NP School Cost?
Graduate nursing tuition varies widely: public university programs are generally the least expensive, private programs the most, with per-credit charges accumulating over a two- to four-year degree. Part-time study lets many nurses keep working — and many hospitals offer tuition assistance that applies to graduate degrees. Practicing NPs are among the higher-paid nursing roles, and the Bureau of Labor Statistics projects strong growth for the occupation, which is why most graduates consider the investment worthwhile. Run your own numbers carefully: total program cost, not just the first-year rate, compared against realistic post-graduation earnings in your state and specialty.
Frequently Asked Questions
Do I need a DNP, or is an MSN enough?
An MSN is enough to certify and practice as an NP in every state. The DNP is optional today, though it may strengthen applications for leadership, academic, and competitive clinical roles.
Can I study to be an NP online?
Much of the coursework in many NP programs is online, but clinical rotations are in person and arranged in approved facilities — the same hybrid pattern as other nursing degrees.
Can I switch specialties later?
Yes, by completing a post-graduate certificate program in the new population focus and sitting for that specialty’s certification exam.
Do NPs prescribe medication?
Yes. Prescriptive authority is part of NP licensure in all states, though the degree of required physician involvement varies by state.
Key Takeaways
- The NP path is: BSN and RN license → MSN or DNP in a population specialty → national certification → state APRN license.
- Expect 6 to 8 years total from the start of nursing school, including graduate study.
- Graduate programs require an RN license, a BSN, and usually RN work experience.
- State practice-authority rules differ — check your state board before committing to a plan.
