What is the CDE/CDCES exam and who administers it?

The Certified Diabetes Care and Education Specialist (CDCES), formerly called Certified Diabetes Educator (CDE), is a credential administered by the Certification Board for Diabetes Care and Education (CBDCE). It validates expertise in diabetes self-management education and support for healthcare professionals working with people who have diabetes or prediabetes.

What is the format of the CDCES exam?

The CDCES exam is a computer-based, multiple-choice test delivered at Pearson VUE testing centers across the United States. Candidates have four hours to complete it, and each question has four answer options with only one correct response. The test is proctored and closed-book.

How many questions are on the CDCES exam?

The CDCES exam contains 200 multiple-choice questions, of which 175 are scored and 25 are unscored pretest items used for future exam development. Candidates cannot distinguish scored from unscored questions, so every item should be answered carefully within the four-hour window.

What is the passing score for the CDCES exam?

CBDCE uses a scaled scoring system with a passing scaled score of 425 out of a possible 600. The raw number of correct answers needed varies by exam form based on difficulty, but roughly 70 percent correct is typically required. Results are provided immediately after testing.

What topics are covered on the CDCES exam?

The exam blueprint covers five domains: assessment, intervention, disease management, professional practice, and program or population management. Content spans pathophysiology, medications, nutrition, physical activity, monitoring, psychosocial issues, acute and chronic complications, and behavior change strategies across type 1, type 2, and gestational diabetes.

What are the eligibility requirements to sit for the CDCES exam?

Candidates need an active, unrestricted U.S. professional license or registration in a qualifying discipline, a minimum of two years of professional practice, and at least 1,000 hours of diabetes care and education experience within the prior five years, with 40 percent earned in the most recent year. Fifteen hours of continuing education in diabetes are also required.

How do you register for the CDCES exam?

Applicants submit an online application through the CBDCE website at cbdce.org, pay the examination fee (currently 350 dollars for the initial attempt), and receive an Authorization to Test email once approved. Candidates then schedule their test appointment directly with Pearson VUE within a 90-day eligibility window.

What are the best preparation tips for the CDCES exam?

Start with the official CBDCE Examination Handbook and content outline, then study ADA Standards of Care and the ADCES Core Concepts curriculum. Use practice tests to identify weak domains, review medication classes and insulin regimens thoroughly, and focus on applying knowledge to patient scenarios rather than memorizing facts.

Candidates have four hours to complete the CDCES certification exam. (Verified Oct 21, 2026 against Certification Board for Diabetes Care and Education.)

Sample Certified Diabetes Educator Test Practice Questions

Try these questions from our free Certified Diabetes Educator Test practice tests. The correct answer and an explanation follow each question.

A diabetes educator is helping a patient interpret their CGM glucose variability. A coefficient of variation (CV) above what threshold is considered high glycemic variability?
- A. 18%
- B. 26%
- C. 36%
- D. 45%

Answer: C. 36%

A CV above 36% is generally considered high glycemic variability and is associated with increased hypoglycemia risk regardless of mean glucose.

What is the ADA-recommended blood pressure target for most adults with diabetes and hypertension?

A. <120/80 mmHg
B. <130/80 mmHg
C. <140/90 mmHg
D. <150/90 mmHg

Answer: B. <130/80 mmHg

The ADA recommends a blood pressure target of <130/80 mmHg for most adults with diabetes and hypertension to reduce cardiovascular risk.

Peer support in diabetes education is effective primarily because it:

A. Replaces the need for professional diabetes education
B. Provides lived-experience modeling and reduces feelings of isolation
C. Offers medically supervised group therapy
D. Guarantees improved glycemic outcomes

Answer: B. Provides lived-experience modeling and reduces feelings of isolation

Peers with shared experiences normalize the challenges of living with diabetes and serve as credible role models, which Social Cognitive Theory identifies as vicarious learning.

A patient using a CGM notices persistent signal loss alerts. Which troubleshooting step should the educator recommend first?

A. Replace the transmitter immediately
B. Check that the receiver or smartphone is within 20 feet of the sensor
C. Recalibrate with a fingerstick glucose
