A Nurse Practice Act (NPA) is a set of state laws that defines what nurses are legally allowed to do, sets the requirements for getting and keeping a nursing license, and establishes the process for disciplining nurses who violate those rules. Every U.S. state and territory has its own NPA, and together with the accompanying rules and regulations, these laws form the legal foundation for all nursing practice in that jurisdiction.
The core purpose is public safety. A state’s duty to protect people who receive nursing care is the legal basis for requiring a license in the first place. If you’re a nurse, your NPA is the single most important legal document governing your career.
What a Nurse Practice Act Covers
While every state’s NPA is different, most address the same core areas. They define the scope of practice for each level of nursing, including licensed practical nurses (LPNs), registered nurses (RNs), and advanced practice registered nurses (APRNs). Scope of practice means the specific tasks, procedures, and responsibilities a nurse at each level is legally authorized to perform. An RN’s scope is broader than an LPN’s, and an APRN’s scope may include diagnosing conditions and prescribing medications, depending on the state.
NPAs also establish the requirements for initial licensure: what education you need, which exams you must pass, and any background checks or other criteria. They spell out renewal requirements too, such as continuing education hours and timelines for keeping your license active. Beyond licensure, NPAs typically define the composition and authority of the state’s board of nursing, the body responsible for enforcing the law.
The Role of the Board of Nursing
Each state’s NPA creates or empowers a board of nursing (BON) to carry out the law’s provisions. The BON is the regulatory agency that reviews license applications, sets administrative rules that add detail to the NPA’s broader language, investigates complaints, and takes disciplinary action when nurses violate the law. Think of the NPA as the legislation passed by lawmakers, and the BON’s rules and regulations as the more specific guidelines that fill in the gaps.
This distinction matters because a BON can update its rules more quickly than a state legislature can amend the NPA itself. When nursing practice evolves, for instance with telehealth or new technologies, the BON may issue updated rules while the broader statute catches up.
How Discipline Works Under the NPA
One of the most consequential sections of any NPA is the disciplinary framework. Anyone can file a complaint against a nurse: patients, employers, colleagues, or members of the public. Once a complaint is received, the process generally follows a predictable path.
The board first reviews the complaint to determine whether it falls within its jurisdiction and whether there’s enough information to move forward. If it does, the BON conducts a formal investigation, gathering evidence, interviewing witnesses, and reviewing relevant records. Based on those findings, the board may hold informal or formal hearings where the nurse has an opportunity to respond.
If the board determines the nurse violated the NPA or its regulations, the consequences range in severity. Options include formal reprimands, fines, mandatory probation with conditions, license suspension, or outright revocation. The severity matches the violation. A documentation error and a case of patient harm are treated very differently. Final disciplinary actions are reported to national databases, employers, and other regulatory bodies, which means the consequences follow a nurse across state lines.
Why NPAs Vary by State
Because each state passes its own NPA through its own legislature, the laws can differ significantly from one state to the next. The biggest variations tend to involve APRN practice authority. Some states grant APRNs “full practice authority,” meaning they can evaluate patients, diagnose conditions, and prescribe medications independently. Other states require APRNs to work under a formal agreement with a physician, sometimes called a collaborative practice agreement or supervisory arrangement.
Prescriptive authority is another area of divergence. In some states, nurse practitioners can prescribe controlled substances with no restrictions. In others, they face limitations on which drug schedules they can prescribe or need physician co-signatures. Supervision requirements for LPNs also vary, as does the list of procedures RNs can perform, such as whether a registered nurse can assist with sedation under a physician’s order.
These differences have real practical consequences. A nurse who moves from one state to another, or who picks up travel assignments, needs to understand the specific NPA in each state where they practice. What’s within your scope of practice in one state could be outside it in another.
Multistate Licenses and the Nurse Licensure Compact
The Nurse Licensure Compact (NLC) allows nurses to hold a single multistate license and practice in any participating state. But a multistate license doesn’t mean one set of rules applies everywhere. Nurses with multistate licenses are subject to the laws and NPAs of both their home state and every compact state where they practice. If you’re an RN licensed in Texas practicing via telehealth with a patient in Virginia, you must follow Virginia’s NPA for that encounter.
Disciplinary provisions under the compact reinforce this. If a nurse commits a violation in a state where they hold a privilege to practice (rather than their home-state license), that state can take action against the nurse’s privilege to practice there. The home state may also impose its own discipline. The infraction is handled as if the offense took place in the state’s own jurisdiction, regardless of where the nurse was physically located. In practice, this means a single violation can trigger consequences in multiple states.
Recent Changes to State NPAs
NPAs are living laws that get updated as healthcare evolves. A recent example is New Mexico’s HB 178, signed into law in 2025, which made several notable changes. The bill waives initial licensure fees for new graduates of New Mexico nursing programs, introduces a reserve license category that allows retired nurses to practice during emergencies, and formally defines “advanced practice registered nurse” in state statute for the first time.
The New Mexico update also gives nurses the option to choose a single-state or multistate license, clarifies that RNs can assist with sedation under a physician’s or prescriber’s order, and creates a framework for developing rules around artificial intelligence in nursing practice. These kinds of updates reflect broader national trends: expanding APRN authority, reducing barriers to entry for new graduates, addressing workforce shortages, and keeping pace with technology.
At the national level, the NCSBN publishes a Model Nursing Practice Act that serves as a template for states. The current version was approved in 2021 after a review process that began in 2018, aimed at reflecting the current regulatory environment and removing language that doesn’t support public safety. States aren’t required to adopt the model act, but it influences how legislatures draft and revise their own NPAs.
How to Find Your State’s NPA
Your state’s NPA is public law, and the full text is available through your state board of nursing’s website. The NCSBN also maintains a directory at ncsbn.org/npa where you can look up the NPA and associated rules for any U.S. state or territory. If you’re a nursing student, a working nurse, or considering moving to a new state, reading the relevant NPA is worth the time. It’s the document that defines what you can and can’t do, and the one that determines what happens if those boundaries are crossed.
