01Basic and Applied Sciences
This domain tests whether you can explain digestion, absorption, macronutrient roles, energy balance, and the components of energy expenditure accurately enough to set safe nutrition targets. The exam favors applied understanding: why protein needs rise with activity, why weight change is not linear, and when a client needs referral rather than another meal plan.
304 words, about 2 min02Assessment
This domain tests client intake, readiness, dietary assessment, anthropometrics, body composition, and interpretation. The exam wants you to collect enough data to coach safely without turning screening into diagnosis.
251 words, about 1 min03Program Design
This domain tests how you turn assessment data into a practical nutrition plan: energy targets, macronutrient distribution, food selection, timing, and progressive adjustments. The best answer is usually the plan the client can sustain, not the most aggressive one.
270 words, about 1 min04Exercise Technique and Training Instruction
This domain tests general physical-activity guidance and safe exercise instruction within nutrition-coach scope. You should know FITT-VP, basic technique cues, intensity monitoring, and when to refer for clinical clearance or qualified exercise instruction.
235 words, about 1 min05Client Relations and Behavioral Coaching
This domain tests rapport, communication, behavior-change theory, and adherence. The exam expects collaborative coaching: evoke the client's reasons for change rather than lecturing.
221 words, about 1 min06Professional Development and Responsibility
This domain tests scope of practice, ethics, confidentiality, evidence-based practice, and referral. The nutrition coach educates and coaches within defined limits; medical nutrition therapy and diagnosis belong to licensed clinicians.
