Naturopathic Doctor Licensure

Licensure for naturopathic doctors provides many benefits:

  • Allows for better patient healthcare.
  • Creates public safety in relation to alternative therapies.
  • Reduces healthcare costs via prevention.
  • Ultimately has a positive effect on the entire medical community.

In order to be licensed as a primary care, general practice physician by a state or jurisdiction which requires licensing, one must:

  1. Graduate from a four-year, professional-level program at a federally accredited naturopathic medical school.
  2. Study a curriculum which includes current medical science and traditional naturopathic theory.
  3. Take and pass national board exams: Naturopathic Physicians Licensing Exam (NPLEX). This rigorous exam covers basic sciences, diagnostic and therapeutic subjects and clinical sciences.

Licensed states and provinces

Candidates for full licensure must also satisfy all licensing requirements for the individual state or province in which they hope to practice. Most of the states and provinces that license naturopathic physicians also have health care systems which allow patients to use naturopathic doctors as their primary care physician.

Currently, 17 states, five Canadian provinces, the District of Columbia, and the US territories of Puerto Rico and the US Virgin Islands all have laws regulating naturopathic doctors (NDs). In these states and provinces, naturopathic doctors are required to graduate from a four-year, residential naturopathic medical school and pass an extensive postdoctoral board examination (NPLEX) in order to receive a license.

Licensed naturopathic physicians must fulfill state- or province-mandated continuing education requirements annually, and have a specific scope of practice defined by the law in their state or province.
