The NBNSC-CNSC exam is a core requirement for the Certified Nutrition Support Clinician (CNSC) certification at the Professional level.

Candidates will face 220-250 (220 scored, 25-30 pre-test) questions and have 240 minutes to complete the exam. This means you need strict time management. We strongly recommend taking timed practice tests to ensure you can maintain a steady pace without rushing when under actual exam time pressure.

The official examination fee is $360 (ASPEN members), $460 (non-members), and you must achieve a score of 500 (scaled score, range 200-800) to pass. Since retaking the test requires paying the full fee again, utilizing accurate practice materials for thorough self-assessment beforehand is crucial to protect your investment.

Candidate requirements include: Active professional license/registration in relevant field (RD/RDN, RN, PharmD, MD/DO, etc.); recommended 2 years of nutrition support practice experience. Please verify all eligibility details on the official certification page before scheduling your appointment.

Registration is handled through official testing partners. The exam is delivered via In-person testing centers or live remote proctored, computer-based. You can sign up here:
