- DEC's exam pulls 20 questions from a pool covering six published content areas.
- You need 15 correct answers (75%) to pass, regardless of which domains those questions come from.
- Your $10 Test ID is valid for a year and lets you retake the test as many times as needed.
- Domain 3 (temperature/time) and Domain 5 (handwashing) tend to carry the most practical, memorization-heavy detail.
Overview: How DEC Structures the Exam
The Alaska Department of Environmental Conservation (DEC), Division of Environmental Health, Food Safety and Sanitation Program, publishes exactly six content areas that define what appears on the Food Worker Card examination. These aren't arbitrary study categories invented by test-prep companies - they are DEC's own published domains, and every one of the 20 randomly drawn questions on your test traces back to one of them.
Understanding the six domains matters because the exam doesn't hand you a syllabus with page numbers. It draws from a pool, meaning two candidates testing on the same day can see different question combinations while still being evaluated against the same six subject areas. If you want a broader breakdown of how difficult that pool actually is to study for, see our complete difficulty guide, and if you want the mechanics of the 75% cutoff explained in detail, read our passing score breakdown.
Domain 1: Receiving Food From an Approved Source
Receiving Food From an Approved Source
This domain covers the very first checkpoint in food safety: making sure food entering a facility comes from a source DEC recognizes as approved, and that it arrives in condition suitable for service. Candidates should understand what makes a supplier "approved" versus questionable, and what red flags on delivery should prompt rejection.
- Recognizing signs that a shipment should be refused (damaged packaging, temperature abuse, pest evidence)
- Understanding why sourcing matters for traceability during a foodborne illness investigation
- Basic expectations for inspecting deliveries before they're stored
Domain 2: Food Protection
Food Protection
This is a broad domain concerned with keeping food safe from contamination throughout storage, prep, and service. Expect questions about cross-contamination prevention, proper storage order, covering and labeling food, and protecting food from physical, chemical, and biological hazards.
- Separating raw and ready-to-eat items during storage and prep
- Preventing contamination from chemicals, pests, and unclean equipment
- General principles of protecting food throughout the flow of service
Domain 3: Temperature and Time Requirements for Potentially Hazardous Foods
Temperature and Time Requirements
Potentially hazardous foods - the ones that support bacterial growth if mishandled - are governed by strict temperature and time rules. This domain tests whether candidates understand safe holding temperatures, cooling and reheating expectations, and why the combination of time and temperature (not just one or the other) determines safety.
- Cold holding, hot holding, and the danger zone concept
- Why foods can't sit at unsafe temperatures even briefly without consequence
- How improper cooling or reheating creates risk even after initial cooking is correct
Key Takeaway
Domain 3 rewards memorizing concrete numbers and sequences rather than general reasoning - flashcards work better here than broad reading.
Domain 4: Food Worker Health and Hygiene
Food Worker Health and Hygiene
This domain addresses when a sick or symptomatic worker must be restricted or excluded from handling food, and general hygiene expectations like clean clothing, hair restraints, and not working while ill with certain symptoms or diagnosed illnesses.
- Symptoms that require reporting to a supervisor
- Difference between restriction from certain duties and full exclusion from the workplace
- Personal hygiene habits expected of anyone handling food
Domain 5: Handwashing Procedures
Handwashing Procedures
Handwashing gets its own dedicated domain because it's one of the single most effective interventions against foodborne illness. Expect direct, specific questions about when hands must be washed and the correct procedure for doing so - not just "wash your hands," but the sequence and duration.
- Situations that require an immediate handwash (after touching raw meat, using the restroom, handling trash, etc.)
- Correct steps: wetting, soaping, scrubbing time, rinsing, and drying
- Why hand sanitizer alone doesn't replace proper handwashing in most situations
Domain 6: Effective Washing and Sanitation of Food Contact Surfaces
Washing and Sanitizing Food Contact Surfaces
The final domain covers the cleaning and sanitizing of anything that touches food - cutting boards, utensils, prep tables, dishware. Candidates should know the difference between cleaning (removing visible debris) and sanitizing (reducing pathogens to safe levels), plus the general order of operations.
- Wash, rinse, sanitize sequence and why order matters
- Why sanitizing without cleaning first is ineffective
- Basic awareness of sanitizer contact time and surface air-drying
How the 20 Questions Are Pulled From the Domains
The exam consists of 20 questions randomly selected from DEC's larger question pool, and a passing score requires at least 15 correct - 75%. Because the questions come from a pool rather than a fixed test form, the exact number of questions per domain can vary between attempts. This is part of why our pass rate data article emphasizes broad domain coverage over cramming a single topic.
Testing itself happens two ways: online through DEC's Food Worker Card system using a myAlaska login, or on a printed test at a DEC program office. Either path draws from the same six domains. Before you can sit for either version, you'll need to purchase a $10 Test ID, which stays valid for one year - plenty of time to retake the test as many times as needed if you don't pass on the first try. For the full fee and logistics breakdown, see our certification cost guide, and for scheduling specifics see testing windows and deadlines.
| Domain | Core Focus | Typical Question Style |
|---|---|---|
| 1. Receiving From an Approved Source | Delivery inspection, supplier standards | Scenario: accept or reject a delivery |
| 2. Food Protection | Contamination prevention, storage order | Identify the safe practice among options |
| 3. Temperature and Time Requirements | Holding, cooling, reheating limits | Numeric recall and applied scenario |
| 4. Health and Hygiene | Illness reporting, exclusion/restriction | "What should the worker do" scenario |
| 5. Handwashing Procedures | When and how to wash hands | Sequence-ordering or trigger-recognition |
| 6. Washing and Sanitizing Surfaces | Clean vs. sanitize, order of steps | Process-order and terminology questions |
Mapping a Study Plan to the Six Domains
You don't need an elaborate study system to prepare for six domains and 20 questions, but sequencing your review does help retention. A short, focused plan built around DEC's actual handbook content works better than generic exam-prep advice borrowed from unrelated certifications.
Foundations
- Read the free DEC handbook cover to cover once
- Review Domain 1 (approved sources) and Domain 2 (food protection) concepts
Numbers-Heavy Domains
- Drill Domain 3 temperature/time thresholds with flashcards
- Take DEC's free practice test to gauge recall
Hygiene and Handwashing
- Focus on Domain 4 and Domain 5 scenario questions
- Practice sequencing the correct handwashing steps
Final Review
- Cover Domain 6 cleaning/sanitizing order of operations
- Do a full mixed practice run and schedule your test

Who Actually Gets Tested on These Domains
Any covered food worker in Alaska must obtain a Food Worker Card within 30 days of hire, which means these six domains apply broadly across restaurants, grocery delis, school kitchens, food trucks, and seasonal cannery or lodge food service - common entry points into Alaska food service jobs. There's one notable exemption: workers who hold a current, valid Certified Food Protection Manager certificate don't need the DEC food-worker card at all, since that credential already covers equivalent material at a higher level.
One geographic wrinkle worth knowing: facilities regulated by the Municipality of Anchorage require an Anchorage-issued card and won't accept the state DEC card, while DEC-regulated facilities elsewhere accept either a current state card or a current Anchorage card. If you're unsure whether your worksite falls under DEC or Anchorage jurisdiction, check our eligibility and requirements guide before registering.
Once you pass, the card is valid for three years from the date of successful testing, and you can print up to three additional copies while it remains valid - useful if you work multiple jobs or need a replacement. Hang onto your Test ID and invoice number; they're how you retrieve results and reprint your card later. For a fuller picture of what the credential unlocks over that three-year window, see our ROI analysis and earnings guide.
Key Takeaway
Know your jurisdiction before you test - an Anchorage employer will not accept a state DEC card, so confirm which system applies to your workplace first.
If any of this terminology is still new to you - the acronym itself, what the card represents, or how it differs from formal manager-level certification - our foundational explainers cover the basics: What Is AK-FWC?, AK-FWC Meaning, and What Does AK-FWC Stand For?. For readers weighing formal coursework versus self-study, AK-FWC Training outlines available preparation options, and you can begin testing your domain knowledge immediately with practice questions at akfwcexam.com.
FAQ
DEC does not publish fixed per-domain weighting for the 20 randomly drawn questions, so it's safest to study all six domains thoroughly rather than assume any one is emphasized more.
Domain 3, temperature and time requirements for potentially hazardous foods, tends to involve the most specific numbers and sequences, making flashcard-style review especially useful there.
No. Your $10 Test ID is valid for one year, and you can retake the test as many times as needed within that period using the same unexpired Test ID.
Not quite. DEC-regulated facilities accept either a current state card or a current Anchorage card, but facilities regulated by the Municipality of Anchorage require the Anchorage-issued card specifically and will not accept the state DEC card.
Yes. Workers who hold a current, valid Certified Food Protection Manager certificate are exempt from the DEC food-worker-card requirement altogether.
