Nursing in the United States is regulated at the state level. There is no national nursing licence and no federal nursing regulator. What exists instead is a statute in each jurisdiction — the nurse practice act — and a board of nursing that writes rules under it, issues licences, and disciplines licensees.
This structure is the reason so much about American nursing varies by state line: what a practical nurse may do, whether a nurse practitioner needs a physician's signature, how many continuing education hours a renewal requires, and what happens to a nurse who is accused of something.
The practice act
A nurse practice act is ordinary state legislation. It typically defines nursing and its levels, creates the board and sets its powers, establishes the requirements for licensure, lists the grounds for discipline, and grants the board authority to write administrative rules filling in the detail.
The distinction between the statute and the rules matters in practice. The statute changes only when the legislature acts. The rules — which contain most of the operative detail a working nurse needs — are written and revised by the board, usually through a public comment process. A nurse who wants to know whether a specific activity is permitted is almost always looking for a rule or a board position statement rather than the act itself.
The first of these laws, North Carolina's in 1903, was a registration act rather than a practice act: it protected the title "registered nurse" and said nothing about what nursing was. New Jersey, New York, and Virginia followed within the same year, and by 1923 every state then in the Union had one. New York wrote the first statutory definition of nursing practice in 1938. See history of nursing and scope of practice.
None of it arrived on its own. The principle — that nursing sets its own entry standard and holds its own register — was argued for over thirty years in Britain by Ethel Gordon Fenwick, against opposition that included Florence Nightingale, and won in the Nurses Registration Act of 1919. In the United States the same campaign was run by Isabel Hampton Robb, Adelaide Nutting and Lavinia Dock through the organizations they had built for the purpose. Nutting holds Maryland registered nurse card number one; Dock's particular insistence was that nurses rather than physicians must control the register, which is why boards of nursing are separate bodies today.
Boards of nursing
A board of nursing is an administrative agency, usually appointed by the governor, composed of nurses and public members. Some states have one board covering both registered and practical nursing; a few maintain separate boards for each. Counting separate practical-nursing boards and the territories, there are 58 boards in the United States that share licensure data nationally.
Boards do four things. They set and enforce the standards for approving nursing education programs in the state. They issue and renew licences. They investigate complaints and impose discipline. And they answer scope questions, usually through published position statements and advisory opinions, which carry considerable weight even though they are not law.
A board's duty runs to the public, not to nurses. This is stated openly in board materials and is worth internalizing: the board is not a professional association and is not a nurse's advocate. Professional associations lobby for nurses; boards regulate them. The two are sometimes confused because both include the word nursing and both publish standards.
Discipline
Grounds for discipline are listed in each practice act and typically include practising without a valid licence, practising beyond scope, patient abuse or neglect, diversion of controlled substances, impairment, falsification of records, criminal conviction, and failure to report certain events.
Sanctions range from a private letter of concern through public reprimand, fine, mandatory education, practice restriction, probation, suspension, and revocation. Many states also operate an alternative-to-discipline programme for nurses with substance use disorders, allowing confidential monitored recovery instead of a public disciplinary record, on the theory that a punitive-only regime drives impaired nurses underground.
Discipline is public and portable. The national coordinating body maintains a database, Nursys, through which participating boards share licensure and disciplinary data; a nurse disciplined in one state does not escape it by licensing in another.
The national coordinating body
The individual boards are members of a national organization, the National Council of State Boards of Nursing. It is not a regulator and has no authority over any nurse. What it does is produce the infrastructure that individual state boards could not build alone: the licensing examination used by every state, the shared licensure and discipline database, model practice act language, and joint policy work with the professional associations — the delegation guidelines and the scope decision framework are both products of this collaboration.
The multi-state licence
Because licensure is state-based, a nurse practising across a state line traditionally needed a licence in each. The Nurse Licensure Compact is an interstate agreement that lets a nurse hold one multi-state licence, issued by the state of primary residence, valid for practice in every other compact state under those states' laws.
The compact has grown substantially — 43 jurisdictions had joined as of this writing, though enacting the compact and implementing it are different milestones, and several states that have passed the legislation are still working through implementation. The controlling detail for any individual nurse is the state of primary residence, which determines which board issues the licence and which board disciplines it. Practice in a compact state remains subject to that state's practice act, not the home state's; the compact moves the licence, not the rules.
The compact does not cover advanced practice. A separate advanced practice compact has been drafted but is not in force on the same footing.
