The National Board of Nutrition Support Certification (NBNSC) is an independent credentialing board established in 1984 by the American Society for Parenteral and Enteral Nutrition (ASPEN).

Why Certify?

NBNSC certification provides an avenue to demonstrate that you have attained the skills and knowledge necessary to provide quality nutrition support care. We have determined the body of knowledge needed to have an understanding of nutrition support and developed a fair and valid means to test care providers including physicians, dietitians, pharmacists, physician assistants, and nurses.

Certified professionals are recognized as quality providers of nutrition support by the public, their colleagues, other members of the healthcare team, and administrators. The Certified Nutrition Support Clinician ® (CNSC®) certification can provide job mobility, open up job opportunities, and, in some cases, lead to promotion and monetary gain.

Objectives of Certification

To promote enhanced delivery of safe and effective care through the certification of qualified clinicians in nutrition support by:

  • Recognizing formally those individuals who meet eligibility requirements of the National Board of Nutrition Support Certification, Inc. and pass the certification examination for nutrition support clinicians.
  • Encouraging continued professional growth in the practice of nutrition support.
  • Establishing and measuring the level of knowledge required for certification by a nutrition support clinician.
  • Providing a standard of minimum knowledge deemed appropriate for clinicians practicing nutrition support; thereby assisting the public, healthcare professionals, and employers in the assessment of nutrition support clinicians.

Important Updates to NBNSC's Credentialing Program

Nutrition Support is an inter-professional field. After conducting extensive research, NBNSC developed a new credential, the CNSC® that is fair and valid for all professional disciplines involved in nutrition support. The dietitians, nurses, pharmacists, physician assistants, and physicians who provide care share a common body of knowledge and expertise that NBNSC has captured in the new exam format. The content of the exam reflects the tasks that healthcare professionals provide on a daily basis.
