The National Board of Nutrition Support Certification, Inc. (NBNSC) is an independent credentialing board. The NBNSC was established in 1984 by the American Society for Parenteral and Enteral Nutrition (ASPEN) to administer certification programs in specialized nutrition support: the Certified Nutrition Support Clinician® (CNSC®) certification program. Nutrition support is a sophisticated and specialized practice that requires the expertise and knowledge of multiple health-care professionals including physicians, dietitians, pharmacists, physician assistants, dentists, and nurses.
Through its credentialing program, NBNSC determines the body of knowledge needed to have an understanding of nutrition support, develops a fair and valid means to test applicants, and promotes the credential to other healthcare professions and organizations. The CNSC® exam is a US-based exam and may relate to practice in the US. The CNSC® certification enables all health-care practitioners involved in nutrition support to identify themselves as qualified caregivers. NBNSC has certified more than 4,200 nutrition support professionals.
NBNSC's mission is to promote the enhanced delivery of safe and effective nutritional care through the certification of qualified clinicians practicing nutrition support.
ASPEN is an individual professional membership society which has established standards of patient care and professional responsibility in the area of specialized nutrition support. The development of standards of practice, clinical guidelines, and the establishment of the the NBNSC to administer certification programs ASPEN has made to enhance delivery of safe and effective nutrition support for the protection of the public. The NBNSC, Inc. is an independent non-profit corporation managed by a separate Board of Directors.
