What Is CSC?

What Is CSC?

CSC stands for Certified Sous Chef, a professional culinary credential administered by the American Culinary Federation (ACF) through its Certification Commission. It is designed for working cooks who already carry supervisory responsibility in a kitchen - overseeing a station, a shift, or a small team - and who want an industry-recognized mark validating that competence. Because the acronym CSC is shared by unrelated credentials in other fields, it's worth stating plainly: on this site, and in this article, CSC refers exclusively to the ACF's Certified Sous Chef designation, not any IT, government, or security certification that happens to use the same three letters.

Earning the CSC involves two distinct components: a written knowledge examination and a hands-on practical examination. This site focuses primarily on preparing for the written exam, though understanding how the two pieces fit together is essential for planning your path. If you're just starting to research the credential, the CSC Certification overview and the CSC Requirements guide are good companion reads before you register.

Who Issues the CSC and Why It Matters

The ACF is the primary professional body for culinarians in the United States, and its Certification Commission oversees a tiered ladder of credentials that track a chef's career progression - from entry-level cook certifications up through executive-level designations. CSC sits at the sous chef tier, positioned for cooks who supervise but aren't yet running an entire kitchen. Because the credential is tied to a recognized federation rather than a single employer or school, it travels with you across kitchens and regions.

Eligibility Routes and Required Coursework

Before you can sit for the written exam, you need to satisfy experience and education prerequisites. The ACF recognizes several entry paths:

• An ACFEF Culinary Arts Program Certificate plus four years of entry-level culinary experience
• An associate degree in culinary arts plus three years of qualifying experience
• Completion of an ACFEF apprenticeship totaling 4,000 on-the-job hours and 420 hours of related instruction

On top of whichever entry route applies, candidates must document at least two years supervising a shift or food station, and that supervisory experience must have occurred within the preceding ten years - so decades-old kitchen management experience won't count on its own.

Three mandatory courses are also required, each totaling 30 hours: Nutrition, Food Safety and Sanitation, and Supervisory Management. If you completed any of these courses more than five years ago, you'll need an eight-hour refresher to keep them valid for certification purposes. For a full breakdown of every path and edge case, see CSC Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Written Exam Format and Scoring

The CSC written examination consists of 100 multiple-choice questions delivered in a 90-minute window. It's administered through the ACF Online Learning Center, which requires an approved proctor to be physically present with you during the test - this isn't a remote-proctoring-only setup, so you'll need to arrange a qualifying testing location in advance.

The exam is closed-book. You're permitted a basic nonprogrammable calculator and scratch paper, but no reference materials, notes, or smart devices. To pass, you need a scaled score of 72. Written exam results remain valid for two years, which gives you a window to complete the practical exam if you haven't already.

The Six CSC Exam Domains

The written blueprint, per ACF's September 1, 2021 handbook revision, organizes questions into six subject areas. Not all domains carry equal weight - Cooking and Safety and Sanitation dominate the question count, which should directly shape how you allocate study time.

Because Cooking and Safety and Sanitation together account for 62 of the 100 questions, a study plan that treats all six domains equally is a mistake. For a full content breakdown of each domain with sample topics, see CSC Exam Domains 2026: Complete Guide to All 6 Content Areas.

The Practical Exam

Passing the written exam is only half the journey. The CSC also requires a practical examination lasting 2 hours, with a passing criterion of 75%. Unlike the written test, the practical involves an in-person cooking demonstration at an approved host site, and candidates are responsible for host-site fees and food costs separately from the certification package. Practical results are valid for one year, which is shorter than the two-year window on written results - so timing matters if you pass one component well ahead of the other.

This site is focused on written exam preparation, but if you're mapping your full certification timeline, factor the practical's shorter validity window into your scheduling from day one.

Fees and Registration Mechanics

The CSC certification package costs USD 250 for ACF members and USD 490 for nonmembers. That package fee covers the certification process itself; it does not include the practical exam's host-site and food expenses, which are billed separately and vary by location and menu requirements.

And before you register, check CSC Exam Dates 2026: Testing Windows, Deadlines & Scheduling to make sure a proctor and testing slot are available when you need them.

Certification Validity and Renewal

Once earned, CSC certification is valid for five years. Renewal requires 80 continuing education hours (CEHs), and at least 25% of those hours must come from volunteer work, leadership roles, or competition activities - not just passive coursework. Renewal also requires current food-safety training and any applicable refresher courses if your original coursework has aged past the five-year mark. Members with uninterrupted ACF membership throughout the preceding five years may have recertification fees waived, which is another point in favor of maintaining membership rather than letting it lapse.

Who Pursues CSC and Why

CSC candidates are typically cooks who already function as a sous chef, station lead, or shift supervisor and want formal recognition that aligns with the next step in their career - whether that's a promotion, a move to a higher-volume kitchen, or eligibility for ACF's higher-tier credentials down the road. Hotels, resorts, country clubs, hospital and institutional food service, and independent restaurants with structured kitchen hierarchies are common employers that value the credential when hiring or promoting into sous chef roles.

Building a CSC Study Plan

Because Cooking and Safety and Sanitation together make up nearly two-thirds of the written exam, an effective study plan front-loads those two domains before spreading remaining time across Baking and Pastry, Nutrition, Finance, and Team Management and Supervision. A simple technique like timed practice blocks - reviewing one domain intensively for a few days, then rotating - works well here specifically because it mirrors the exam's own weighting rather than a generic even split.

A structured, domain-weighted approach like this is covered in more depth in CSC Study Guide 2026: How to Pass on Your First Attempt. If you'd rather condense everything into a single reference document for last-minute review, the CSC Cheat Sheet 2026: One-Page Review of Must-Know Facts is built for that purpose. You can also run full-length timed practice exams over at the main practice test site to simulate the real 90-minute format before test day.
