CDCES study guide: three domains and where answers slip
This CDCES study guide works through CBDCE's content outline one domain per section: what the domain covers, the mistakes that lose marks there, and 8 worked questions at the end. Care and Education Interventions alone accounts for 105 items out of 150, which is why its section is the longest.
The current blueprint is the Examination Content Outline effective July 1, 2024, based on the 2023 practice analysis. CBDCE's PDF of it still has 2019 in its file name; the document inside is the 2024 edition. As of November 2026, CBDCE keeps the 2024 outline until a new practice analysis is completed.
Each form has 150 scored items in three domains of very unequal size, so study time should follow the counts below rather than the order of a textbook.

5.3%
Domain I: Assessment, 37 items
This domain is the work that comes before any teaching. The outline divides it into physical and psychosocial status (history, a diabetes-focused exam, labs, mental health and the social conditions a person lives in), self-management behaviors and knowledge (eating, activity, medication taking, monitoring, device use, risk reduction, problem solving), and learning: goals, readiness, preferred ways of learning, and literacy, numeracy and digital skills.
In the scenarios on this site, this domain usually asks what to ask, or which finding matters most. The best choice is the one that uncovers the obstacle this person has, which is often practical: cost, schedule, eyesight, a job that makes lows dangerous.
Reacting to the number alone
Our scenarios often pair a result with a sentence from the person. That sentence often carries the answer, because it is where cost, culture, fear or a home situation shows up. A choice that responds only to the number, without the context the stem gave, is usually a distractor.

Domain II: Care and Education Interventions, 105 items
About 70% of the scored exam falls in this domain, most of it in one subdomain: person-centered education on self-care behaviors. That subdomain alone outweighs the other two domains combined. Its list reads like a curriculum: nutrition, physical activity, medications, monitoring, acute and chronic complications, problem solving, and living with diabetes from childhood to old age, pregnancy included. The rest of the domain covers the disease process and approach to treatment, an education plan built with the person and the team, and evaluation, documentation and follow-up.
The outline treats medication from the educator's side. You need the classes, how each is taken and stored, which ones raise the risk of lows, and what changes before surgery or during illness. Choosing a drug is the prescriber's decision, and in our scenarios a choice in which the educator alters a regimen without a protocol is not the answer.
The monitoring strand covers reading a CGM report as well as a meter: time in range, time below range and the ambulatory glucose profile, along with when a fingerstick is still needed.
GMI is an estimate, not a lab A1C
The glucose management indicator is calculated from average CGM glucose. It often differs from a laboratory A1C drawn over the same months, and that gap is expected. A choice that treats the difference as a device fault or a lab error misreads the report.
Illness does not mean stopping insulin
When a person who uses insulin is sick and eating little, the right answer is rarely to stop it. Basal insulin continues, glucose and ketones are checked more often, fluids matter, and the plan says when to call the team. Options that skip insulin "until eating again" are built to look careful.

Domain III: Standards and Practices, 8 items
The smallest domain, about 5.3% of the scored exam, is about the rules programs work under rather than one person's care: the National Standards for Diabetes Self-Management Education and Support (DSMES), the standards of the National Diabetes Prevention Program, practice guidance from ADA, AACE and the Endocrine Society, population health, team-based care, advocacy, prevention, and disparities in care.
The National Standards are short enough to read in full, and with so few items in the domain, a careful read of them is the cheapest preparation on the outline.
DSMES and the DPP serve different people
The National DPP is a lifestyle program for people at risk of type 2 diabetes, prediabetes included; DSMES is education and support for people living with diagnosed diabetes. A distractor may offer the right program to the wrong person.
Which guidelines the exam follows
Under the handbook, national guidelines released as effective immediately can be tested right away, while other advances wait at least a year. Study from material that matches the current ADA Standards of Care rather than an older edition.
Beyond this page, the outline PDF and the candidate handbook are worth reading in full, and the handbook includes sample questions. Professional associations and publishers sell review guides; none of them is a CBDCE document. CBDCE requires no course, though it lists some preparation programs it has reviewed (CRPPs).

Worked questions across the three domains
8 questions0 done · 0 agree with the key
Assessment · 24.7%Question 1 of 8
A 35-year-old with type 1 diabetes collected a urine albumin-to-creatinine ratio (UACR) the morning after an intense training session; the result is 45 mg/g. Previous results were normal. What is the MOST appropriate next step?
Choose a letter. The key opens with a short note under each of the choices.
One high value taken right after hard training cannot establish albuminuria, which requires persistence across repeat samples.
BAdvise a protein intake of 0.6 g/kg/dayCheck
Nothing justifies protein restriction on one doubtful sample, and for non-dialysis kidney disease ADA sets about 0.8 g/kg/day as the limit, not a lower figure.
CStop all exercise until the UACR normalizesCheck
Stopping exercise is the wrong response: the rise is a short-lived effect of exertion, not kidney harm from training, and giving up activity does not settle the result.
DRepeat UACR after a day without hard exerciseCheck
Strenuous exercise in the previous 24 hours can raise albumin excretion for a short time, so the sample is repeated under usual conditions; albuminuria is confirmed only when two of three samples over 3–6 months are high.
Assessment · 24.7%Question 2 of 8
A 52-year-old with type 1 diabetes for 30 years reports that lows are now found mostly by CGM alarms rather than by symptoms. Which assessment question BEST screens for impaired hypoglycemia awareness?
AHow many lows have you treated this week?Check
A count of treated lows measures frequency, and lows that go unfelt may never be counted, so the number cannot screen for lost awareness.
BAt what reading do you start to feel low?Check
Impaired awareness means warning symptoms appear only at low levels, often below about 54 mg/dL, or not at all. The reading at which a person first notices a low is the idea behind validated screens such as the Clarke questionnaire.
CWhat do you usually use to treat a low?Check
This checks treatment knowledge once a low is found; it does not show whether warning symptoms still arrive in time.
DDo you keep glucagon at home and at work?Check
Glucagon access belongs in a safety review, but owning a kit tells nothing about whether the person still senses a low coming.
Assessment · 24.7%Question 3 of 8
A 36-year-old with type 1 diabetes for 15 years using insulin pens reports random highs after meals and unexpected lows over the past 2 months. Food records confirm accurate carbohydrate counting, and there are no missed doses or changes in activity. They report no nausea, early fullness, or bowel changes, and their weight is stable. Which assessment should the diabetes care and education specialist prioritize?
ARefer for a gastric emptying studyCheck
Gastroparesis can mismatch food and insulin timing, but without nausea or early fullness an invasive test comes well after a simple site exam.
BScreen for celiac disease with tTG-IgACheck
Celiac disease is more common in type 1 diabetes, yet with stable weight and no bowel symptoms a lab screen does not come before a bedside check of the sites where the insulin goes in.
CInspect and palpate the injection sitesCheck
Fifteen years of pen injections often leave lipohypertrophy, firm rubbery tissue that absorbs insulin erratically and produces this mix of highs and lows. Looking and feeling for it is quick and comes first.
DIncrease the basal insulin dose by 10%Check
This is a dose change rather than an assessment, and more basal insulin would deepen the unexpected lows before their cause is known.
Interventions · 70%Question 4 of 8
A 34-year-old with type 1 diabetes has an A1C of 6.2% and 88% time in range. They say they check their CGM constantly, feel exhausted by it, and add, "I can't ever take a day off." What should the educator do FIRST?
AAsk about the emotional burden of self-managementCheck
Exhaustion and "never a day off" point to diabetes distress, which can sit alongside excellent numbers. Exploring that burden comes before any change to the plan.
BPraise the results and encourage more of the sameCheck
Praise for the numbers brushes past the exhaustion just described and pushes the person to keep up an effort they say they cannot sustain.
CSuggest loosening the glucose targetsCheck
Changing targets before understanding the distress assumes the goal itself is the problem; any target change is a shared decision that follows the assessment.
DRecommend switching to automated insulin deliveryCheck
Recommending automated insulin delivery may lighten the work later, but switching devices first skips the conversation about what is wearing this person down.
Interventions · 70%Question 5 of 8
An adult with type 1 diabetes is learning carbohydrate counting using standard servings. Lunch is 1 cup of cooked pasta, 1 small apple, and 1 cup of fat-free milk. About how many grams of carbohydrate does this meal contain?
A57 gCheck
57 g comes from counting the cup of pasta as only 30 g, an underestimate that would leave the meal bolus too small.
B60 gCheck
60 g leaves out the milk; milk is often filed as a protein food, but its lactose counts toward the meal's carbohydrate.
C72 gCheck
At 15 g per carbohydrate serving, 1 cup of cooked pasta is about 45 g (one-third cup per serving), the small apple 15 g, and a cup of fat-free milk about 12 g, for roughly 72 g.
D87 gCheck
87 g counts the pasta as 60 g, four servings instead of three, so the bolus would be too large.
Interventions · 70%Question 6 of 8
A person with type 1 diabetes and unstable housing asks to start an insulin pump. Their insurance has lapsed twice in the past year. Which initial step BEST balances access to technology with safety?
ADeny the request until housing is stableCheck
Denying the request until housing is stable withholds pump therapy because of social circumstances instead of planning for safety.
BStart the pump now; plan supplies laterCheck
Starting now and planning supplies later sets up an interrupted pump with no long-acting insulin on board, a path to DKA within hours.
COffer a pump once the A1C is below 7%Check
Making the pump wait for an A1C below 7% treats eligibility as something earned, and people with higher A1C often gain the most from the device.
DPlan steady supplies and an injection backupCheck
A pump stops working without sets, reservoirs, and insulin. Securing a supply route and teaching a pen or syringe fallback lets the person use the technology without risking DKA when coverage lapses.
Standards · 5.3%Question 7 of 8
A Medicare beneficiary began initial DSMT on March 15. By July 1 they had completed a 1-hour individual assessment and 5 hours of group classes. They have no documented barrier to group learning. On November 1 of the same year, what remains of their initial DSMT benefit?
A4 hours, delivered in group sessionsCheck
Initial DSMT covers up to 10 hours in a continuous 12-month period, 9 of them in group sessions. After the assessment hour and 5 group hours, 4 hours remain, delivered in group sessions, and November is still inside 12 months of the March start.
B3 hours of group plus 1 hour individualCheck
Splitting the rest into 3 group hours plus 1 individual hour assumes an individual hour is still left; it was spent on the assessment, and more would need a documented barrier or a specific order.
C4 hours, individual or group as they chooseCheck
Four hours is the right count, but letting the person choose individual sessions is not: the remaining initial hours are delivered in a group unless a barrier to group learning is documented, and none is.
D5 hours, delivered in group sessionsCheck
5 hours would be left only if the assessment hour did not count, but it is part of the 10-hour initial benefit.
Standards · 5.3%Question 8 of 8
During an accreditation review, a surveyor finds that participants' records end with the final class: goals were set and outcomes measured, but nothing documents what happens next. Which element required by the 2022 National Standards for DSMES is missing?
AA repeat A1C drawn at the final classCheck
Outcomes were already measured, and one more lab value at the last class leaves follow-up support just as undocumented.
BA plan for ongoing self-management supportCheck
The National Standards expect each participant to leave with a personalized plan for continued support after the program, because gains from education fade without follow-up.
CA certificate of completion for each personCheck
A certificate only marks attendance and is not a standards element; it sets out no next steps.
DA satisfaction survey completed at the last classCheck
A satisfaction survey records how the class felt to participants; it documents nothing about the support the person will get afterward.
The outline gives nutrition no separate count. It is one strand of the self-care subdomain in Care and Education Interventions, next to activity, medications, monitoring and complications. If you come from dietetics, the medication and device strands will probably need more of your time than food.
Do I need the ADCES review guide to pass?
No. CBDCE requires no review course or book. It recognizes some preparation programs it has reviewed, but none is required. What is tested is set by the content outline; the handbook explains it, and the ADA Standards of Care are one of the practice standards it names.
The outline PDF says 2019. Is it out of date?
No. Only the file name carries the old year; the document is the outline effective July 1, 2024, which every form is built from today.
