CDM Exam Flashcards

Q: What does the CDM, CFPP credentialing exam cover?

The exam is built on five domains effective March 1, 2025: Sanitation and Safety (24%), Foodservice (22%), Nutrition (20%), Personnel and Communications (20%), and Business Operations (14%). It contains 160 multiple-choice items (140 scored) over 3 hours and is administered for CBDM through PSI.

Q: What is the passing score for the CDM exam?

There is no fixed percentage; CBDM sets a criterion-referenced cut score using a modified Angoff procedure based on subject-matter-expert judgments of a minimally competent dietary manager. Historically, answering about 70% of the scored items has been required to pass, and roughly 75% of candidates pass on the first attempt.

Q: How much does the CDM exam cost and how is it scheduled?

The CBDM credentialing exam fee is $425. After CBDM approves eligibility, candidates schedule and take the computer-based exam through PSI within their assigned testing window. A new application and fee are required for each retake.

Q: How long do I have to wait to retake the CDM exam?

Candidates must wait 90 days between retake attempts of the CDM, CFPP credentialing exam, and a new application plus the exam fee is required for each attempt.

Q: How do I maintain the CDM, CFPP credential after passing?

Certificants complete 45 continuing education hours every 3 years - including at least 9 hours in Sanitation and Safety and 1 hour in Professional Ethics - and pay the annual certification renewal fee to keep the credential active.

Q: What is the temperature danger zone tested on the CDM exam?

Under the FDA Food Code, the temperature danger zone is 41 degrees F to 135 degrees F, the range in which pathogens grow most readily. TCS foods should spend no more than a cumulative 4 hours in this zone, and food safety is a major exam focus because CDMs also hold the Certified Food Protection Professional (CFPP) designation.

Question 1

What is the temperature danger zone for TCS (time/temperature control for safety) foods?

Accepted Answer

41 degrees F to 135 degrees F. Pathogens multiply fastest in this range, so TCS foods must move through it quickly. CDMs design holding, cooling, and reheating procedures to keep food out of this zone.

Question 2

What is the maximum cumulative time a TCS food may spend in the temperature danger zone before it must be discarded?

Accepted Answer

4 hours total. Once a TCS food has been in the 41-135 degrees F range for a cumulative 4 hours, it must be thrown out - it cannot be re-cooled and reused, because toxins may already have formed.

Question 3

What is the two-stage cooling rule for hot TCS food?

Accepted Answer

Cool from 135 degrees F to 70 degrees F within 2 hours, then from 70 degrees F to 41 degrees F within an additional 4 hours - 6 hours total. If the first 2-hour stage is missed, the food must be reheated or discarded.

Question 4

Why is poultry cooked to a higher minimum internal temperature than ground beef or fish?

Accepted Answer

Poultry must reach 165 degrees F for 15 seconds because it commonly carries Salmonella and Campylobacter. Higher-risk products and the surface-to-interior contamination of poultry require this top minimum-cook standard.

Question 5

To what internal temperature must previously cooked TCS food be reheated for hot holding, and how fast?

Accepted Answer

165 degrees F for 15 seconds within 2 hours. Rapid reheating limits time in the danger zone; reheating only to holding temperature is not adequate to make leftovers safe.

Question 6

What is the difference between cleaning and sanitizing?

Accepted Answer

Cleaning removes visible food, soil, and grease from a surface; sanitizing reduces pathogens on an already-clean surface to safe levels. A surface must be cleaned first - sanitizer cannot work through residue.

Question 7

In HACCP, what is a critical control point (CCP)?

Accepted Answer

A step where a control can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level - such as cooking or cooling. Not every step is a CCP; CCPs are the points where loss of control would create an unacceptable risk.

Question 8

In HACCP, what is a critical limit?

Accepted Answer

The maximum or minimum measurable value that a CCP must meet to control a hazard - for example, cooking chicken to 165 degrees F. Exceeding a critical limit triggers a corrective action.

Question 9

What is cross-contamination, and name one common prevention practice?

Accepted Answer

The transfer of pathogens from one food, surface, or person to ready-to-eat food. Prevent it by using separate color-coded cutting boards and utensils, storing raw meats below ready-to-eat foods, and washing hands between tasks.

Question 10

In a cooler, why is raw poultry stored on the bottom shelf below ready-to-eat foods?

Accepted Answer

Storage order follows minimum cooking temperature: items needing the highest cook temperature go lowest. Raw poultry (165 degrees F) sits at the bottom so its drips cannot contaminate foods cooked to lower temperatures or eaten as-is.

Question 11

What is the FIFO method and what food safety goal does it serve?

Accepted Answer

First In, First Out - stock is rotated so older product is used before newer product. It minimizes spoilage and the risk of serving expired food by ensuring items are used before their use-by date.

Question 12

What is the most effective single action a foodhandler can take to prevent foodborne illness, and when is it required?

Accepted Answer

Proper handwashing with soap and warm water for about 20 seconds. It is required after using the restroom, handling raw food, touching the face or hair, taking out trash, and before putting on gloves.

Question 13

What does the CFPP designation signify within the CDM, CFPP credential?

Accepted Answer

Certified Food Protection Professional - it recognizes that the holder has demonstrated food safety and sanitation competency. It is why Sanitation and Safety is the largest exam domain (24%) and why 9 of 45 recertification CE hours must be in that area.

Question 14

What is a standardized recipe and why is it central to foodservice operations?

Accepted Answer

A tested recipe that produces consistent quality, yield, and portion size every time when followed exactly. It controls food cost, supports accurate purchasing and nutrient analysis, and ensures consistency regardless of which cook prepares it.

Question 15

What is yield in recipe management, and how does a yield adjustment work?

Accepted Answer

Yield is the number and size of portions a recipe produces. To scale a recipe, multiply each ingredient by a conversion factor (desired yield divided by original yield) so portions and cost stay accurate at the new volume.

Question 16

What is portion control and why does it matter to a dietary manager?

Accepted Answer

Serving a consistent, predetermined amount per resident or patient. It controls food cost, ensures each person receives the planned nutrients (important for therapeutic diets), and keeps service equitable and predictable.

Question 17

What is a cycle menu?

Accepted Answer

A set of menus rotated over a fixed period (for example, 4 weeks) before repeating. It simplifies purchasing, forecasting, and production planning while still offering variety, which makes it common in long-term care.

Question 18

What is the difference between AP (as purchased) and EP (edible portion) weight?

Accepted Answer

AP weight is the weight when received, including trim and waste; EP weight is what remains after preparation. The yield percentage links them and is essential for accurate purchasing quantities and true food cost.

Question 19

What should a receiving clerk verify when food is delivered?

Accepted Answer

That items match the purchase order and invoice in quantity, price, and quality, and that TCS foods arrive at safe temperatures (cold at 41 degrees F or below). Out-of-spec or unsafe items should be rejected at the dock.

Question 20

What is par level in inventory management?

Accepted Answer

The minimum quantity of an item that should be on hand before reordering. Setting par levels prevents both stockouts and over-ordering, which ties up cash and increases spoilage.

Question 21

What is the difference between perpetual and physical inventory?

Accepted Answer

Perpetual inventory is a running record updated as items move in and out; physical inventory is an actual hand count of stock on shelves. Physical counts verify and correct the perpetual record and feed food-cost calculations.

Question 22

What is the difference between a cook-serve and a cook-chill production system?

Accepted Answer

Cook-serve prepares food for immediate service; cook-chill cooks food, rapidly chills it, stores it, and reheats it later. Cook-chill improves planning and labor efficiency but demands strict cooling and reheating controls.

Question 23

What is production forecasting and what data drives it?

Accepted Answer

Estimating how much food to prepare to meet demand. It uses historical production records, census or headcount, menu popularity, and known events - reducing both shortages and costly overproduction.

Question 24

What is batch cooking and why is it used in volume foodservice?

Accepted Answer

Preparing food in smaller quantities throughout the service period instead of all at once. It keeps food fresher, preserves quality and nutrients, and limits time in the temperature danger zone.

Question 25

What are the six classes of essential nutrients?

Accepted Answer

Carbohydrates, proteins, fats (lipids), vitamins, minerals, and water. Carbohydrates, proteins, and fats provide energy (calories); vitamins, minerals, and water do not but are essential for body function.

Question 26

How many calories per gram do carbohydrates, protein, fat, and alcohol provide?

Accepted Answer

Carbohydrate 4, protein 4, fat 9, and alcohol 7 calories per gram. Fat is the most energy-dense, which is why high-fat foods raise calorie totals quickly - useful for calorie calculation questions.

Question 27

What is nutrition screening and how does it differ from a full nutrition assessment?

Accepted Answer

Screening is a quick process to identify residents at nutritional risk; assessment is the in-depth evaluation that follows for those flagged. A CDM typically performs screening and refers at-risk individuals to the dietitian.

Question 28

What are the four steps of the Nutrition Care Process (NCP)?

Accepted Answer

Nutrition assessment, nutrition diagnosis, nutrition intervention, and nutrition monitoring and evaluation. It is a standardized framework that gives dietetics professionals a consistent way to deliver and document care.

Question 29

What is a therapeutic (modified) diet?

Accepted Answer

A diet altered in texture, consistency, or nutrient content to treat a medical condition - for example, a 2-gram sodium diet for heart failure. It must be ordered by a physician or authorized provider.

Question 30

What is the purpose of a mechanical soft or pureed diet, and who typically needs it?

Accepted Answer

It modifies food texture for people with chewing or swallowing difficulty (dysphagia) or poor dentition, reducing choking and aspiration risk while still meeting nutrient needs. The level is matched to the person's swallowing ability.

Question 31

What is the difference between enteral and parenteral nutrition?

Accepted Answer

Enteral nutrition delivers formula into a functioning GI tract via a feeding tube; parenteral nutrition delivers nutrients directly into the bloodstream (IV) when the gut cannot be used. "If the gut works, use it" favors enteral feeding.

Question 32

What is a clear liquid diet used for, and why is it not nutritionally complete?

Accepted Answer

It provides fluids and some energy from transparent liquids (broth, gelatin, clear juice) before procedures or to rest the GI tract. It lacks adequate protein, calories, and most nutrients, so it is meant only for short-term use.

Question 33

Why is dehydration a major nutritional concern in long-term care, and what are warning signs?

Accepted Answer

Older adults have a blunted thirst response and may limit fluids, raising the risk of confusion, UTIs, and falls. Signs include dark urine, dry mouth, decreased intake, and sudden weakness - CDMs help monitor and encourage fluids.

Question 34

What is unintended weight loss and why is it a clinical red flag?

Accepted Answer

Weight loss not planned by the resident, often signaling poor intake, illness, or dysphagia. Significant unintended loss (such as 5% in one month) triggers nutrition intervention and is a focus of regulatory survey scrutiny.

Question 35

What is a nutrient-dense food, and how does it differ from an energy-dense food?

Accepted Answer

Nutrient-dense foods supply many nutrients relative to calories (for example, vegetables, lean protein); energy-dense foods are high in calories per gram, often from added fat or sugar. Nutrient density matters most for at-risk eaters with small appetites.

Question 36

What is the role of fortification in foodservice nutrition?

Accepted Answer

Adding nutrients or calories to ordinary foods - such as adding protein powder or extra fat to mashed potatoes - to boost intake for residents who eat small volumes. It increases nutrition without increasing serving size.

Question 37

What is the difference between recruitment and selection in staffing?

Accepted Answer

Recruitment is attracting a pool of qualified applicants; selection is choosing the best candidate from that pool through screening, interviewing, and reference checks. Strong recruitment makes effective selection possible.

Question 38

What is the difference between orientation and ongoing training?

Accepted Answer

Orientation introduces a new employee to the organization, job, and policies in the first days; ongoing training builds and refreshes skills over time. Both are required, but they serve different points in the employee's tenure.

Question 39

What is a job description and how does it differ from a job specification?

Accepted Answer

A job description lists the duties and responsibilities of a position; a job specification lists the qualifications (skills, education, experience) a person needs to perform it. Together they guide hiring, training, and evaluation.

Question 40

What is progressive discipline?

Accepted Answer

A stepwise corrective approach that escalates - typically verbal warning, written warning, suspension, then termination - giving the employee a chance to improve. It promotes fairness and documents the process if termination becomes necessary.

Question 41

What is the difference between training and coaching as a supervisor?

Accepted Answer

Training teaches new knowledge or skills, usually in a structured group setting; coaching is individualized, ongoing feedback to improve a specific employee's performance. Coaching reinforces and personalizes what training introduced.

Question 42

Why are master and daily work schedules both used in a dietary department?

Accepted Answer

The master schedule sets a recurring staffing pattern that ensures shifts are covered consistently; the daily schedule adjusts for absences, census changes, and special needs. The master schedule provides stability; the daily schedule provides flexibility.

Question 43

What is the difference between formal and informal communication in a department?

Accepted Answer

Formal communication follows official channels (memos, policies, the chain of command); informal communication is the unofficial "grapevine" among staff. Effective managers use formal channels for decisions while staying aware of the informal network.

Question 44

What is the value of an in-service training session in foodservice?

Accepted Answer

A short, on-site education session (for example, on handwashing or new equipment) that updates staff skills and reinforces compliance. In-services document ongoing training and are commonly reviewed during regulatory surveys.

Question 45

What is the difference between an operating budget and a capital budget?

Accepted Answer

An operating budget covers day-to-day recurring costs (food, labor, supplies); a capital budget covers major long-term purchases such as a new oven or walk-in cooler. They are planned and approved separately.

Question 46

What is food cost percentage and how is it calculated?

Accepted Answer

The share of revenue spent on food: cost of food sold divided by food sales, times 100. It is a core control metric - a rising percentage signals waste, theft, over-portioning, or pricing problems.

Question 47

What is the difference between a fixed cost and a variable cost?

Accepted Answer

Fixed costs stay the same regardless of meals served (rent, salaried staff); variable costs rise and fall with volume (food, disposables, hourly labor). Distinguishing them is essential for budgeting and break-even analysis.

Question 48

What are competitive bids and how do they support cost control in purchasing?

Accepted Answer

Requesting quoted prices from multiple approved vendors for the same specifications, then selecting the best value. Bidding controls cost, ensures fair vendor treatment, and is often required for large or public-sector purchases.

Question 49

What is a purchase specification, and why does it precede purchasing decisions?

Accepted Answer

A detailed, written description of an item's required quality, size, grade, and packaging. Specs ensure vendors quote on identical products so bids are comparable and deliveries meet the operation's standards.

Question 50

Why must a dietary department maintain survey-ready documentation and follow CMS regulations?

Accepted Answer

Federally certified facilities must meet CMS Conditions of Participation; surveyors review records such as temperature logs, sanitation checks, therapeutic diet orders, and training. Continuous, accurate documentation - not last-minute cramming - keeps the department compliant and avoids citations.
