A CNS has an advanced degree (master's, doctoral, or professional level), in nutrition or closely allied subject, and has additionally met the stringent requirements of the American College of Nutrition (ACN)'s certifying arm, the Certification Board For Nutrition Specialists (CBNS). Since 1995, this has included successful performance on a rigorous written examination covering the broad science of nutrition, ranging from basic aspects through clinical and research applications. CNS's are required to maintain their certification by earning extensive continuing nutrition education (CNE) credits, generally through attendance at educational programs in nutrition, such as ACN's annual scientific/clinical meetings. CNS's are urged to be active members of ACN.

The Certification Board For Nutrition Specialists (CBNS) was founded in 1993 by the American College of Nutrition (ACN) to help meet the growing demand for knowledgeable, responsible professional nutritionists. The CBNS was created as a national certifying body in response to the many advanced degree nutritionists (master's and doctoral level) from regionally accredited institutions that seek more formal recognition of their knowledge, skills and experience.
CBNS certification provides the public a way to distinguish highly trained, competent nutritionists with assurance. The protected title of Certified Nutrition Specialist (CNS) is awarded by CBNS to those nutritionists meeting defined educational, experience and examination requirements. Continuing education requirements help ensure that standards of excellence are maintained. CNS diplomats are found in a variety of professional settings in private practice, public and community health care, universities and industry. Since 1998, CBNS certification has been extended to include physicians with similar expertise and experience in basic and applied nutrition. Some of the most recognized names in the field of nutrition hold the CNS credential.
