The CNS®

The Certified Nutrition Specialist® credential (CNS®) is the most advanced certification for personalized nutrition practitioners. Certified Nutrition Specialists practice science-based personalized nutrition therapy to power people to health. They are spearheading the transformation from population-based to personalized nutrition, and from disease care to authentic health care. The CNS designation demonstrates to colleagues, clients, employers and the public that certified individuals have the knowledge and proficiency required for advanced professional nutrition practice. To be eligible for the CNS credential, an individual must have a minimum of a master’s degree in nutrition or a related health science, meet specified coursework requirements, achieve a passing score on the rigorous Certification Examination for Nutrition Specialists, and document achievement of a set of clearly defined practice competencies in 1000 hours of Supervised Practice Experience (SPE).

The Supervised Practice Experience (SPE)

Satisfactory completion of the CNS SPE is essential to being awarded the CNS® credential. The CNS SPE consists of 1,000 hours of supervised practice in personalized nutrition assessment, intervention, and monitoring to address both prevention and management of a broad range of health issues.

The SPE program is designed to support the supervisor in covering all designated competencies with the candidate while empowering supervisors and candidates to tailor the experience to meet individual career goals. It is structured to ensure each candidate obtains the in-depth knowledge and skills expected of an advanced-level nutrition professional as outlined in CNS SPE Competencies. The SPE may be obtained entirely or in part from internship, residency or clinical rotation, clinical practice setting, community setting, institutional setting, home health care setting, and/or practicum as part of a master's or doctoral degree program.
