ExploreAbout this exam
The NASM Fitness Nutrition Specialist (FNS) is a nutrition-focused credential intended for fitness professionals who want to add evidence-based nutrition coaching to their training practice. Candidates typically come from personal training, group fitness, wellness coaching, or strength and conditioning backgrounds and want to help clients with eating behaviors, body composition goals, and long-term lifestyle change without practicing clinical dietetics. Because NASM's public course catalog lists its nutrition offering as the Certified Nutrition Coach (CNC), candidates researching the FNS should confirm the current product name, exam blueprint, and policies directly with NASM before enrolling or scheduling. Nutrition content in NASM's wellness pathway emphasizes food's impact on health, working through common nutrition myths, flexible eating styles, and evaluating supplementation for long-term health, all delivered through behavior-change coaching rather than rigid meal plans. The broader NASM curriculum is organized into six sections: professional development and responsibility; client relations and behavioral coaching; basic and applied sciences and nutrition concepts; assessment; exercise technique and training instruction; and program design. Preparation should combine the self-paced online course with applied practice: calculating and interpreting client assessments, translating nutrition guidance into sustainable habits, and rehearsing motivational interviewing. Study in short, spaced sessions, take the end-of-section quizzes, and reserve the final week for full-length practice and reviewing missed items. NASM states its programs are built and peer-reviewed by expert contributors and supported by scholarly references, so expect questions that test reasoning and application rather than memorized definitions.
What you'll study
About NASM FNS preparation
Is the NASM FNS exam open book or proctored?
NASM does not publish FNS-specific exam rules on its public pages. For comparison, the Certified Wellness Coach exam is delivered online in the customer portal, and the proctored NASM-CPT exam is closed-book. Ask NASM Member Services at 1-800-460-6276 to confirm the FNS format before you schedule.
How many questions are on the FNS exam and how long do I have?
The item count and time limit for the FNS exam are not stated in NASM's public materials. Other NASM credentials use 100 questions in 120 minutes (CWC) or 120 questions in two hours (proctored CPT). Treat those as comparisons only and verify the FNS specification with NASM.
What score do I need to pass?
NASM does not publish an FNS passing score. Its other exams require a minimum of 70%, but you should not assume that carries over. Confirm the passing standard, and whether it is a scaled or raw score, with NASM before your test date.
If I fail, how many retakes do I get?
Retake rules for the FNS are not documented publicly. NASM's CWC exam allows three attempts, with additional retests purchasable through Member Services. The proctored CPT exam allows one attempt and then imposes NCCA retest wait periods of one week, 30 days, and one year.
How long do I have to complete the course and sit the exam?
NASM does not state an FNS enrollment or exam window. For reference, the CWC exam must be completed within 365 days of purchase, and the proctored CPT exam within 180 days of purchase. Ask NASM which window applies to your FNS enrollment.
Is the FNS the same as the NASM Certified Nutrition Coach?
They are not presented as the same product in NASM's current catalog, which lists the Certified Nutrition Coach (CNC) as its nutrition course and does not show a separate FNS listing. Before paying, ask NASM whether FNS content has been folded into the CNC or replaced by it.
What topics should I prioritize when studying?
Focus on the nutrition section of NASM's wellness curriculum: food's impact on health, debunking nutrition myths, flexible eating styles, and evaluating supplements. Pair that with behavior-change material such as motivational interviewing, since nutrition coaching succeeds or fails on adherence, not on information alone.
What trips candidates up most on nutrition exams?
Two patterns dominate. First, overreaching into clinical territory such as diagnosing conditions or prescribing therapeutic diets, which is outside a fitness professional's scope. Second, choosing the most restrictive nutrition plan instead of the sustainable, client-centered option. When two answers look right, pick the one that respects scope of practice and long-term adherence.
How should I sequence my studying?
Work through the course sections in order, since assessment and program design build on the sciences section. Take each section quiz immediately after finishing it, then revisit missed items a week later. In the final week, do timed practice under exam conditions and review explanations rather than just correct letters.
Does NASM offer payment plans for nutrition courses?
Yes. NASM advertises a variety of 0% interest payment plans and directs candidates to call 1-800-460-6276 or enroll online to see current options. Pricing changes frequently, so confirm the current FNS or CNC price and any bundle discounts directly rather than relying on older figures.
