- The CFC written exam has 100 questions, 120 minutes, and a 75% passing requirement, covering four competency areas.
- The four domains are Sanitation and Safety, Nutrition, Introduction to Food Service, and Basic Food Preparation.
- The separate 150-minute cooking practical fails automatically if the safety/sanitation evaluation is unacceptable.
- Candidates need 15-hour courses in nutrition and food safety/sanitation, which line up directly with two exam domains.
How the CFC Written Exam Is Built
Certified Fundamentals Cook is awarded by the American Culinary Federation (ACF) through its Certification Commission. The individual pathway described in the CFC handbook combines two separate gates: a written knowledge assessment and a hands-on cooking practical. This guide focuses on the written side, where the four official knowledge competencies, which we treat as the exam's domains, define what you can be asked.
The written assessment contains 100 questions to be completed in 120 minutes, delivered through the ACF Online Learning Center. A locally identified, disinterested third-party proctor oversees it, which means you arrange your testing environment rather than walking into a commercial testing center. You need a 75% to pass. The exam is closed book, photo identification is required, and a nonprogrammable calculator is permitted, which hints that some questions involve basic arithmetic such as yields, conversions, or portioning.
Because the handbook lists four competencies and does not publish a percentage split between them, the safest assumption is that you must be solid across all four rather than gambling on a favorite area. If you want the scoring mechanics in detail, see our breakdown of the CFC passing score, and for the broader picture of what the credential demands, read the CFC requirements guide.
Domain 1: Sanitation and Safety
This is the domain with the highest stakes, and not only because of the written questions. Candidates are required to complete a 15-hour course in food safety/sanitation as part of eligibility, and the cooking practical treats an unacceptable safety/sanitation evaluation as an automatic failure regardless of how well the food turns out. In other words, what you learn here is tested twice.
Sanitation and Safety: What to Master
Expect scenario-style questions that ask what a cook should do, not just definitions to recite.
- Foodborne illness basics: how contamination happens and which practices prevent it
- Time and temperature control for holding, cooling, reheating, and cooking foods
- Cross-contamination prevention between raw proteins, ready-to-eat items, and produce
- Personal hygiene: handwashing, glove use, illness policies, and clean uniforms
- Cleaning versus sanitizing, and proper sanitizer concentrations and contact practices
- Safe receiving, storage order, labeling, and FIFO rotation
- Workplace safety: knife handling, slips and falls, burns, and equipment safety
A useful way to study this domain is to walk through a shift mentally: receiving a delivery, storing it, prepping proteins and vegetables, cooking, holding, cooling leftovers, and cleaning down. At each stage, ask what could go wrong and what control prevents it. Questions on the written exam tend to reward that kind of process thinking.
If you have food-handler training from a previous job, do not assume it fully covers this domain. The ACF pathway expects a structured 15-hour course, and the written questions can probe areas that a short certificate course glosses over. Our CFC training overview covers how to approach the required coursework.
Domain 2: Nutrition
Nutrition is the domain that surprises many working cooks. Line experience teaches you flavor, speed, and technique, but it rarely teaches you to explain macronutrients or dietary guidance on paper. Like sanitation, nutrition carries a mandatory 15-hour course requirement, so the exam assumes you have been formally exposed to the material.
Nutrition: What to Master
Focus on the connection between nutrition science and what a cook actually puts on the plate.
- The major nutrient groups and the role each plays in the body
- Vitamins and minerals, including common food sources
- How cooking methods and storage can preserve or reduce nutrient content
- Dietary guidelines and how they translate into balanced menu planning
- Food allergies and intolerances, including ingredient awareness and cross-contact
- Reading and understanding basic nutritional information
- Modifying recipes and cooking methods for healthier outcomes
Because a nonprogrammable calculator is allowed, be comfortable with simple calculations that might show up alongside nutrition concepts, such as portion adjustments or comparing quantities. You do not need advanced math, but you do need to be steady with it under time pressure.
Domain 3: Introduction to Food Service
This domain widens the lens from the individual cook to the operation around them. It is where the exam tests whether you understand how a professional kitchen and dining operation functions, and what your place in it looks like. For candidates who have mostly worked a single station, it can feel less concrete than sanitation or prep, so it rewards deliberate review.
Introduction to Food Service: What to Master
Think about the industry, the kitchen structure, and the professional habits that make a cook employable.
- Types of food service operations and how their needs differ
- Kitchen organization, station roles, and the flow of work through a brigade-style or modern team
- Professionalism: communication, teamwork, punctuality, and accountability
- Basic cost awareness, including portioning, waste, and yield
- Equipment recognition and appropriate use in a commercial kitchen
- Standard recipes, measurements, and kitchen math
- Customer service and the cook's role in the guest experience
Employers across restaurants, hotels, institutional kitchens, and catering operations look for cooks who understand more than their own station. This domain is the bridge between technique and employability, and it ties naturally to the career questions covered in our CFC jobs guide. If you are weighing the credential against your career goals, the CFC ROI analysis walks through that decision.
Domain 4: Basic Food Preparation
Basic Food Preparation is the domain closest to the cooking practical, and it is the one where written knowledge and hands-on skill most directly reinforce each other. The practical asks you to produce a salad and a main course in 150 minutes, demonstrating knife cuts, protein preparation, cooking methods, and presentation. The written exam tests the vocabulary and reasoning behind those same skills.
Basic Food Preparation: What to Master
Know the terms, the reasons behind each technique, and the safe ways to execute them.
- Knife skills and the standard cuts, including when each cut is used and why uniformity matters
- Mise en place: organizing ingredients, tools, and workflow before cooking begins
- Dry-heat cooking methods such as sauteing, roasting, grilling, and broiling
- Moist-heat and combination methods such as steaming, poaching, simmering, and braising
- Protein preparation, including handling, seasoning, doneness, and safe internal temperatures
- Vegetable and salad preparation, including washing, cutting, and dressing
- Seasoning, flavor balance, and basic plating and presentation principles
The written exam is where you prove you can name and explain what your hands already know. A cook who sears chicken every night may still struggle to classify the method or state the reasoning behind it. Practice describing techniques in plain terms: what the method is, what it does to the food, and what can go wrong.
How the Domains Connect to the Cooking Practical
Passing the written exam is only half the pathway. Certification also requires a separate 150-minute cooking practical, and the four written domains map onto it more tightly than most candidates expect.
- Sanitation and Safety is evaluated throughout the practical. An unacceptable safety/sanitation evaluation fails the practical outright, no matter how good the plate looks.
- Basic Food Preparation shows up in your knife cuts, protein preparation, cooking methods, and presentation of the salad and main course.
- Introduction to Food Service appears in how you organize your station, manage time, and conduct yourself professionally.
- Nutrition informs balanced, thoughtful composition of the dishes you produce.
Key Takeaway
Study the written domains with the practical in mind. Every sanitation habit you memorize for the written exam is a habit you must demonstrate under evaluation while the clock runs.
Host-site and food charges for the practical are separate from the ACF exam-processing fee, so plan for them. Our CFC certification cost breakdown explains how the fees fit together, including the difference between member and nonmember pricing.
Sequencing the Domains in Your Prep
Rather than a generic study schedule, the order in which you tackle the domains matters because of how they depend on each other. Start with Sanitation and Safety, since it feeds both the written exam and the practical. Follow with Nutrition while the required course material is fresh, then move to Introduction to Food Service, and finish with Basic Food Preparation so your technique review sits closest to your practical.
Sanitation and Safety
- Review temperature control, cross-contamination, hygiene, and cleaning versus sanitizing
- Build a mental shift walk-through from receiving to closing
Nutrition
- Review nutrient groups, dietary guidance, and allergen awareness
- Practice simple calculator-based questions
Introduction to Food Service
- Study operation types, kitchen organization, equipment, and kitchen math
- Review professionalism and cost awareness basics
Basic Food Preparation and Full Review
- Drill knife cuts, cooking methods, and protein handling vocabulary
- Take timed practice sets on the CFC practice test to simulate the 100-question, 120-minute format
