ExploreAbout this exam
The NPLEX (Naturopathic Physicians Licensing Examinations) are administered by NABNE, the North American Board of Naturopathic Examiners - an independent, nonprofit organization formed as a service to the naturopathic profession and the agencies that license or register naturopathic physicians. Regulatory authorities in the US and Canada (with some exceptions) use NPLEX results as part of the licensure or registration process, so the exams are intended for graduates of approved naturopathic medical programs who are pursuing that credential. The sequence has two stages: the Part I – Biomedical Science Examination, which must be passed before you can sit the Part II – Clinical Science Examinations, comprising Part II – Core Clinical Science and/or the Part II – Clinical Elective. NABNE does not permit taking Part I and Part II within the same administration, so plan your timeline across at least two administrations. The passing standard is set by criterion-referenced standard setting, meaning you are measured against the knowledge and skills required for safe and effective practice rather than against other candidates. Preparation should therefore be broad and practice-oriented: build the biomedical foundation first, then move to clinical reasoning, and use the handbooks and forms on NABNE's site for administrative requirements.

What you'll study
About NPLEX I preparation
Can I take Part I and Part II in the same administration?
No. NABNE policy does not allow applicants to take both the Part I and the Part II Examinations within the same NPLEX administration. You must also have previously passed Part I before you are eligible for the Part II – Clinical Science Examinations, so plan for at least two separate administrations.
What is the difference between Part II – Core Clinical Science and the Clinical Elective?
Part II is applied for as the Part II – Core Clinical Science and/or Part II – Clinical Elective examinations, using the Part II application link. Both fall under the Part II – Clinical Science Examinations and both require that you have previously passed the Part I – Biomedical Science Examination before you are eligible.
How is the passing score set?
NABNE states that, in accordance with testing industry best practices, the passing/cut score is established using a criterion-referenced standard setting methodology. Each candidate is evaluated on their own knowledge and performance rather than in comparison to other candidates, based on the knowledge, skills, and abilities required for safe and effective practice.
When is the application period for the February 2027 administration?
The application period for the February 2027 NPLEX administration will be open October 1-30, 2026. Applications are submitted through the Part I or Part II application links on NABNE's site depending on which examination you are eligible for. Check NABNE's Important Dates page for the full calendar.
I need testing accommodations. What is the deadline?
A Testing Accommodations Request and Evaluator's Report Form, plus all required forms and documentation, must be submitted to [email protected] no later than October 30, 2026 to be considered for the February 2027 NPLEX administration. Submit early so any missing documentation can be resolved before the deadline.
How do I get my results sent to a licensing board?
You can submit a request to have an official transcript of your NPLEX results sent to a regulatory authority by completing the Transcript Request Form and submitting a fee of $30. NABNE sends exam results and transcripts to regulatory authorities as part of its service to licensing and registering bodies.
What are the eligibility requirements to sit the NPLEX?
To be eligible to take the NPLEX, you must have completed the appropriate academic requirements at an approved naturopathic medical program. NABNE's eligibility page and handbooks describe the academic requirements in detail; confirm your program's status and your completion status before the application window opens.
In what order should I study and sit the exams?
Follow the required sequence: prepare for and pass Part I – Biomedical Science first, since it is a prerequisite for the Part II – Clinical Science Examinations. Then build clinical reasoning for Part II – Core Clinical Science, adding the Clinical Elective as your goals require. Because both parts cannot be taken in one administration, sequence your study blocks accordingly.
What is the most common planning mistake candidates make?
Assuming the two parts can be combined in a single administration. NABNE explicitly prohibits taking Part I and Part II in the same administration, and Part II eligibility depends on a prior Part I pass - so a compressed timeline can cost you an entire testing cycle. Map your dates against NABNE's calendar before committing.
Does NABNE offer practice questions or study materials?
NABNE administers the examinations, qualifies candidates, and sends results and transcripts to regulatory authorities; the source material does not describe official practice tests. Candidates typically prepare through their naturopathic medical program curriculum and independent study resources such as this one, which is not affiliated with NABNE.
