Naturopathic Doctor (ND) Eligibility Requirements

There are three eligibility requirements to earn the CNS: Education, Supervised Practice Experience, and Examination.


All candidates must be graduates of an ACNPE-accredited program, OR meet the following degree and coursework requirements:

Degree Requirement
  • Doctor of Naturopathic Medicine (ND) degree from a United States regionally accredited college or university, or its foreign equivalent.
Coursework Requirement
  • Coursework must be from a United States regionally accredited* institution or its foreign equivalent; credits are semester credit hours.
  • Thirty-five semester credit hours of relevant coursework to provide the foundational knowledge for the development of core competencies required for the practice of effective personalized nutrition** as indicated by the CNS Examination Content Outline.

*Regionally accredited means an institution that was accredited, at the time the degree was awarded, by a regional accreditation body in the United States which is recognized by the Council for Higher Education Accreditation and the United States Department of Education. Degrees from institutions outside the U.S. must be from that country’s equivalent of a regionally accredited U.S. institution.

**Personalized nutrition is an interdisciplinary field that draws upon a broad range of sciences to advance human health. It considers the unique makeup of individuals and specifically identified sub-groupings of people with similar characteristics, and encompasses a person-centered approach to nutrition science evidence, education, and clinical care.

Curriculum Overview

Regionally Accredited Graduate Programs & Courses

Supervised Practice Experience

The CNS candidate must demonstrate evidence of experience in nutrition by undergoing a self-directed supervised program which is tailored to each individual candidate’s career goals.

The Practice Experience may commence once the candidate is matriculated in the qualifying degree program. Although the Supervised Practice Experience program may be completed before or after passing the Certification Examination for Nutrition Specialists, it is important to note that historically those who have completed the practice experience perform better on the examination than those who have not.

Each candidate must complete 1,000 hours of supervised practice experience with hours distributed as follows:
  • Nutrition assessment (minimum 200 hours)
  • Nutrition intervention, education, counseling, or management (minimum 200 hours)
  • Nutrition monitoring or evaluation (minimum 200 hours)
  • Remaining hours may be in any of the above categories
All hours must be supervised by a BCNS-approved supervisor who meets the following qualifications:
  • Minimum of three (3) full-time years of clinical experience in nutrition care in one of the following:
    • Certified Nutrition Specialist (CNS) in good standing; or
    • Master of Science or Doctoral Degree in a field of nutrition with a state license or certification (if applicable); or
    • Licensed MD/DO with didactic training or education and experience in clinical nutrition as documented by 75 CE credits or the equivalent (without exception) over the past 5 years; or
    • Doctoral-level health professional (e.g. ND, PharmD) who meets curriculum eligibility requirements for CNS and who can legally provide nutrition services in the state of practice.
    • DCs must also have an MS, Nutrition or be a Certified Nutrition Specialist (CNS) in good standing.

Supervisors may not be married to, related to, or domestic partners of supervisee(s).

NOTE: Candidates are encouraged to have their supervisor(s) approved by BCNS prior to beginning each segment of their practice experience.

Supervised practice experience setting may be any that facilitates the above requirements, including but not limited to:

  • ND residency, clinical rotation or internship
  • Clinical practice
  • Institutional setting
  • Community setting

The Supervised Practice Experience may not be obtained from retail stores.

A variety of experiences with multiple supervisors and settings is encouraged to meet all required competencies.

All candidates are required to use the Personalized Nutrition (PN) Case Data Collection to ensure high quality nutrition care to clients.

Candidates and supervisors review the reports together to review next steps and suggested protocols. Personalized Nutrition Case Studies must:

  • be completely filled in
  • have occurred within the past 5 years of the time they submit their SPE hours to the BCNS
  • be discussed with and approved by their Supervisor(s) – these forms are NOT to be submitted to the BCNS

You now have the ability to download forms and upload completed forms directly through My Portal. Navigate to the Forms & Resource page and select and upload the following forms:

  • Supervisor's Approval Application
  • Candidate's Report
