- CDCES testing is available year-round through either PSI test centers or live remote proctoring-both administered by PSI under CBDCE oversight.
- The exam fee is $350 total, which includes a nonrefundable processing fee; budget accordingly before you register.
- You sit for 175 multiple-choice questions in 4 hours, but only 150 are scored-25 are unidentified pretest items.
- Domain 2 (Care and Education Interventions) carries 105 of the 150 scored questions-it alone represents the majority of your score.
Understanding Your Two Testing Options
When the Certification Board for Diabetes Care and Education (CBDCE) awards eligible candidates access to the CDCES exam, they face an immediate practical decision before a single study hour is logged: Where will you actually sit for the test? PSI, the testing provider contracted by CBDCE, offers two distinct pathways-a traditional brick-and-mortar test center and live remote proctoring (LRP) conducted from your own location. Neither option changes the content you're tested on, the 4-hour time limit, or the 175-question format. But the logistics, risks, and preparation rituals differ enough that your choice deserves deliberate thought.
This guide breaks down both formats in concrete terms, maps the exam's three domains against what you'll encounter on test day, and helps you make a format decision that fits your professional life-whether you're a registered dietitian, pharmacist, nurse, or another qualifying healthcare professional working toward your CDCES credential.
PSI Test Center: What to Expect
PSI operates a network of physical testing centers across the United States and internationally. Candidates who choose this route travel to a designated facility, check in with a proctor in person, and complete the exam on a PSI-managed workstation.
Day-of Logistics
- Arrival time: PSI typically asks candidates to arrive 15-30 minutes before their scheduled appointment. Late arrivals risk forfeiting their slot and their exam fee.
- Identification: Two forms of ID are standard. Your name must match exactly what appears in your CBDCE candidate account.
- Personal items: Phones, notes, food, and drinks are generally prohibited in the testing room. Lockers are provided at most centers.
- Workspace: You work on a PSI-configured computer. The testing interface is standardized-no surprises there if you've practiced on a similar platform beforehand.
Finding a Center Near You
Center availability varies by region. Urban candidates often have multiple options within a short drive; rural candidates may need to plan for travel and overnight accommodations. Because CDCES testing is available year-round, you have flexibility to choose a date that allows for a comfortable commute without compressing your study timeline.
Live Remote Proctoring: Setup and Requirements
Live remote proctoring lets you complete the CDCES exam from your home, office, or another private space-provided that space meets PSI's technical and environmental standards. A human proctor monitors you via webcam and screen share throughout the entire 4-hour session.
Technical Requirements You Must Verify in Advance
- A stable, high-speed internet connection (wired connections are strongly preferred over Wi-Fi)
- A functioning webcam and microphone-both must remain active for the duration of the exam
- A computer that meets PSI's operating system and browser specifications
- A clean, private room with no other people present and minimal background clutter
- Sufficient ambient lighting so the proctor can clearly see your face and immediate workspace
The Check-In Process
Remote candidates typically complete a pre-exam check-in that includes a 360-degree room scan, ID verification via webcam, and a system compatibility check. This process can add 15-30 minutes to your exam day that isn't counted against your 4-hour window-but it does mean you need to log in early and be prepared for a technical review before the clock starts.
Who Benefits Most from Remote Proctoring
Remote proctoring is a practical choice for candidates who live far from a PSI center, have caregiving obligations that make travel difficult, or simply perform better in their own physical environment. Nurses and diabetes educators with irregular shift schedules often find the scheduling flexibility of LRP particularly valuable, since year-round availability paired with at-home testing removes the logistical burden entirely.
Side-by-Side Comparison
| Factor | PSI Test Center | Live Remote Proctoring |
|---|---|---|
| Location | PSI facility; travel required | Your own private space |
| Technical setup responsibility | PSI manages all equipment | Candidate responsible for hardware, internet, environment |
| Scheduling flexibility | Subject to center availability | High; year-round with broader time slot options |
| Day-of interruption risk | Low; controlled environment | Higher; technical or environmental violations can halt exam |
| Exam content and format | Identical: 175 questions, 4 hours | Identical: 175 questions, 4 hours |
| ID and check-in process | In-person with staff | Remote webcam-based ID verification |
| Best for | Candidates near centers; anxiety about tech failures | Candidates far from centers; schedule-constrained professionals |
The CDCES Exam Structure You're Actually Tested On
Regardless of format, every candidate sits for the same exam: 175 multiple-choice questions delivered over 4 hours. Of those 175 questions, 150 are scored and 25 are unidentified pretest items. Pretest items are embedded throughout the exam-you will not know which questions count and which don't. This is by design. Treat every question as scored.
The passing score is set using the Angoff methodology and reported through CBDCE's scoring process. CBDCE does not publicly disclose a raw pass rate, so any figure you encounter elsewhere should be treated with skepticism. What the exam blueprint does tell you is exactly where the scored weight lives-and that information should drive every hour of preparation you invest. Visit our CDCES practice test platform to work through questions mapped to each domain.
Key Takeaway
The 25 pretest questions are invisible to you. Don't try to identify them-pace yourself as if all 175 questions are scored, which means roughly 1 minute and 22 seconds per question on average across the 4-hour window.
Domain Breakdown and Question Weights
The CDCES exam content outline was implemented on July 1, 2024, following a 2023 practice analysis that confirmed three official domains. Understanding what each domain covers-and how many scored questions it represents-is the most important structural knowledge a candidate can have.
Domain 1: Assessment (37 Scored Questions)
This domain tests your ability to gather and interpret patient data to inform diabetes care decisions. Think clinical assessment skills applied specifically to the diabetes population.
- Health history, physical examination findings, and laboratory data interpretation
- Psychosocial factors, health literacy, and cultural considerations
- Identifying barriers to self-management and care engagement
- Recognizing acute and chronic complications that affect care planning
Domain 2: Care and Education Interventions (105 Scored Questions)
This is the dominant domain-105 of the 150 scored questions come from here. It covers the full spectrum of diabetes self-management education and support (DSMES) delivery, behavior change, and clinical intervention knowledge.
- Nutrition therapy, meal planning frameworks, and macronutrient guidance for diabetes
- Physical activity counseling and exercise prescriptions tailored to glycemic management
- Medication management including insulin types, regimens, oral agents, and non-insulin injectables
- Blood glucose monitoring, CGM interpretation, and technology integration
- Behavior change strategies, motivational techniques, and self-efficacy support
- Sick day rules, hypoglycemia management, and prevention of acute complications
- Pregnancy and diabetes, including gestational diabetes management
- Special populations: older adults, pediatric patients, hospitalized patients
Domain 3: Standards and Practices (8 Scored Questions)
The smallest domain by question count, but not one to ignore. It covers the professional and operational framework of diabetes care and education practice.
- DSMES program accreditation standards and quality improvement
- Documentation, coding, and reimbursement considerations
- Scope of practice, professional ethics, and evidence-based practice standards
- ADA Standards of Medical Care and other authoritative clinical guidelines
The weighting here is not subtle. Domain 2 alone accounts for 70% of your scored questions. Any candidate who distributes study time evenly across all three domains is making a quantifiable strategic error. Domain 3's 8 questions are worth mastering-but not at the expense of deep competence in Care and Education Interventions.
Use our CDCES practice questions to drill Domain 2 scenarios until clinical reasoning around medications, CGM data, and behavior change becomes automatic under time pressure.
Registration, Fees, and Scheduling Mechanics
The CDCES exam fee is $350, which includes a nonrefundable processing fee. This is a single charge covering your entire application and exam authorization period-there is no separate scheduling fee when you book with PSI. However, because the processing component is nonrefundable, candidates who are not yet eligible should not register speculatively hoping to meet prerequisites later.
Prerequisites Before You Can Register
CBDCE requires all of the following before a candidate can sit:
- A current, active, unrestricted qualifying professional license, registration, or certification
- At least two years of professional practice in a relevant healthcare role
- At least 1,000 hours of diabetes care and education practice within the required eligibility window
- 15 continuing education hours in diabetes care and education
Once CBDCE verifies eligibility and issues exam authorization, PSI handles scheduling. Year-round testing availability means you can choose a date that fits your clinical schedule-especially valuable for nurses, pharmacists, and dietitians who work rotating shifts or have seasonal patient volume spikes.
Aligning Your Preparation to the Format You Choose
Your delivery format choice has a direct implication for how you structure your final preparation weeks-not just what you study, but how you practice the act of taking this specific exam.
If You're Testing at a PSI Center
Your primary cognitive task is building stamina for 4 hours of concentrated clinical reasoning in an unfamiliar physical space. Practice under timed, distraction-free conditions. Simulate the commute and check-in routine mentally. On the content side, your priority is Domain 2-specifically medication management and behavior change scenarios, which generate the highest question volume and require the most nuanced clinical reasoning.
If You're Using Live Remote Proctoring
Add a technical readiness layer to your prep. At least one week before your exam, run a full PSI system compatibility check in your intended testing space. Verify your webcam, microphone, and internet connection under realistic conditions. Then shift focus entirely back to content-especially the 105-question Domain 2 terrain.
Domain 1: Assessment Foundation
- Review lab interpretation: A1C, fasting glucose, lipid panels, kidney function markers
- Study psychosocial assessment frameworks specific to diabetes populations
- Begin timed practice sets of 20-25 questions to build exam pacing habits
Domain 2: Care and Education Interventions (Deep Work)
- Spend at least half of each study session on Domain 2 content-this reflects its 70% weight
- Drill insulin pharmacology: onset, peak, duration for all major types
- Practice CGM data interpretation scenarios and clinical response decisions
- Study MNT frameworks: carbohydrate counting, glycemic index, renal considerations
- Review behavior change models as applied to DSMES delivery
Domain 3 and Full Simulation
- Complete Domain 3 review: ADA Standards, accreditation requirements, documentation rules
- Take at least one full-length 175-question timed practice exam
- If using LRP: complete your technical environment check this week
- Review weak areas identified during practice sessions on CDCES Exam Prep
Professionals already working in diabetes education will find Domain 2 familiar in subject matter but potentially unfamiliar in exam format. Clinical experience helps with content recall, but the CDCES exam tests application and prioritization-not just memorization. Practicing with CDCES-specific multiple-choice questions is the most direct bridge between your clinical knowledge and exam performance.

Frequently Asked Questions
PSI does allow rescheduling, but policies on format changes and associated fees can vary. Contact PSI directly as soon as you know you need to change your format-waiting until the day before your exam risks forfeiting your $350 fee entirely. CBDCE's authorization period is time-limited, so confirm the rescheduling window in your authorization materials.
Exactly 150 questions are scored. The remaining 25 are pretest items being evaluated for future use. They are embedded randomly throughout the exam and are not labeled-you will not know which questions are scored and which aren't. Answer every question as if it counts.
Yes. Whether you test at a PSI center or via live remote proctoring, you receive the same 175 multiple-choice questions, the same 4-hour time limit, and are evaluated against the same three domains. The July 1, 2024 content outline governs all exams currently being delivered.
Domain 2: Care and Education Interventions is by far the largest, with 105 of the 150 scored questions. It covers the full scope of DSMES delivery-medications, nutrition therapy, glucose monitoring, behavior change, and special populations. Any serious preparation plan must prioritize this domain above all others.
PSI proctors follow specific protocols for technical interruptions. In many cases, a brief disconnection can be resolved and the exam resumed. However, repeated or extended outages may trigger a session termination. PSI recommends a wired internet connection over Wi-Fi specifically to reduce this risk. Review PSI's LRP technical requirements thoroughly before your exam date and run a system check well in advance.
