- The September 2025 reference file lists 12 knowledge domains and publishes no percentage weights.
- Posted fees: USD 50 for application and exam combined, USD 125 certification after passing, USD 50 annual dues.
- The posted exam date is June 8, 2027; the October 5, 2026 application deadline has already passed.
What This Exam Actually Is (and Isn't)
The Diplomate of the ACVPM - Epidemiology Certification is a subsequent specialty credential offered by the American College of Veterinary Preventive Medicine through its Epidemiology Specialty (ACVPM-ES). The specialty Examination Committee establishes the certifying examination. It is open to people who already hold ACVPM diplomate status, which makes it a second-tier certification layered on top of the base board.
That distinction matters for how you study. Much of what turns up when you search for ACVPM epidemiology preparation material is aimed at the main board examination, where epidemiology and biostatistics is one section among several. A flashcard deck titled "ACVPM epidemiology and biostats" almost certainly targets that main-board section, not the specialty. The specialty draws its scope from its own knowledge-domain document, and you should treat that document as your single source of truth for what is in bounds.
Eligibility, Fees, and the Application Packet
Because the specialty is restricted to existing diplomates, the application is as much a portfolio review as a registration. The issuer's posted requirements include the following:
- Standing: You must be an ACVPM diplomate in good standing.
- Experience: At least two years of epidemiology experience within the five years before you apply. Qualifying epidemiology-focused residency or graduate study can count toward this.
- Competency evidence: Normally, coauthorship of a peer-reviewed scientific article within five years. Alternatives considered include a manuscript submitted within the 12 months before the application deadline (with submission confirmation and abstract), or a major authored or coauthored epidemiologic report documenting substantial analysis and preparation.
- Reference letters: At least three, dated within one year of application, from ACVPM diplomates or other epidemiologists. If training counts toward your experience, at least one referee must have been responsible for a significant portion of that training.
The application portal requires ACVPM diplomate access, so you will see its exact forms only once you log in. For a fuller walk-through of each requirement, read DACVPM (Epidemiology) Requirements.
| Cost item | Posted amount | When it applies |
|---|---|---|
| Application and examination (combined) | USD 50 | At application |
| Certification fee | USD 125 | After passing |
| Annual specialty dues | USD 50 | Each year thereafter |
The posted fees are modest compared with many credentialing exams, so the real cost sits in preparation time and the effort of assembling your evidence. A full breakdown lives in DACVPM (Epidemiology) Certification Cost.
The Posted Exam Cycle and What It Means for Planning
The issuer's page posts an examination date of June 8, 2027, with an application deadline of October 5, 2026. As of the verification date, that deadline had already passed. One wrinkle: the indexed page text still described the application period as open, but the explicit deadline is the figure to rely on, and no extension should be assumed.
Practically, this means the 2026 application window is closed for new candidates, and anyone starting now is realistically planning for a future cycle. That is not bad news for your preparation. It gives you a long runway to do three things in parallel:
- Strengthen your competency evidence, for example by getting a manuscript submitted or finalizing a qualifying report.
- Line up reference letters from appropriate diplomates or epidemiologists, remembering that letters must be dated within one year of application.
- Work through the knowledge domains methodically instead of cramming.
Always confirm current dates directly with the issuer, since schedules can change. Our exam dates guide tracks what is posted.
The 12 Official Knowledge Domains
The current reference file, updated September 2025, lists twelve major examination knowledge domains. It publishes no percentage weights, so we do not assign any here. Treat all twelve as fair game and resist the temptation to guess which ones are "worth more."
- Causality
- Measuring Disease Frequency
- Measures of Association
- Data Acquisition, Organization, and Presentation
- Epidemiologic Study Designs
- Risk Analysis
- Error and Confounding
- Conceptual Understanding, Interpretation/Application of Diagnostic Tests
- Epidemiologic Surveillance
- Outbreak Investigation
- Infectious Disease Epidemiology/Modeling
- Biostatistics
Grouping the Domains Into Study Blocks
Twelve domains is a lot to hold in your head. These groupings are an editorial study aid, not issuer categories, but they reflect how the topics build on one another.
Foundations: Causality; Measuring Disease Frequency; Measures of Association
These three domains underpin everything else. Expect to move fluently between incidence, prevalence, and the ratio and difference measures that compare them.
- Distinguish incidence risk from incidence rate, and know when each is appropriate.
- Calculate and interpret risk ratios, rate ratios, odds ratios, attributable fractions, and the population-level versions of each.
- Be ready to defend a causal claim using formal criteria and counterfactual reasoning, not just a correlation.
Design and Validity: Study Designs; Error and Confounding; Data Acquisition, Organization, and Presentation
This block is where critical appraisal lives. A candidate should be able to read a methods section and say what could go wrong.
- Match question to design: cohort, case-control, cross-sectional, ecological, and trial designs each carry characteristic strengths and biases.
- Separate random error from systematic error; identify selection bias, information bias, and confounding, and know how design and analysis address each.
- Choose appropriate ways to organize and present data, and spot misleading displays.
Detection and Response: Diagnostic Tests; Surveillance; Outbreak Investigation
These domains cover applied veterinary public health work.
- Sensitivity, specificity, predictive values, likelihood ratios, and how prevalence shifts predictive values, including interpretation of tests used in series or parallel.
- Surveillance system design and evaluation, including how sensitivity and representativeness of a system affect what you conclude.
- Stepwise outbreak investigation: confirming the outbreak, case definitions, descriptive epidemiology, hypothesis generation and testing, and control measures.
Quantitative Synthesis: Risk Analysis; Infectious Disease Epidemiology/Modeling; Biostatistics
The most calculation-heavy block, and the one where you should practice by hand.
- Risk analysis frameworks and how uncertainty is characterized and communicated.
- Transmission concepts and the logic of compartmental and other infectious disease models.
- Core biostatistics: estimation, hypothesis testing, confidence intervals, and regression approaches appropriate to epidemiologic data.
Working the Reference List and Critical Appraisal
The reference document recommends using the latest available editions of its listed books and critically appraising recent peer-reviewed epidemiologic research across the knowledge domains. It also states that its suggested books, journals, and online resources are explicitly non-exhaustive. Read that as a signal: the exam expects you to reason like a working epidemiologist, not to recite one textbook.
A productive appraisal habit is to pick a recent veterinary or One Health epidemiology paper and interrogate it against several domains at once:
- Design: What design was used, and was it the right one for the question?
- Measurement: How was disease frequency defined and measured, and what measure of association was reported?
- Validity: Where could selection bias, misclassification, or confounding creep in, and did the authors handle it?
- Diagnostics: If a test defined case status, what do its sensitivity and specificity imply for the estimates?
- Inference: Do the conclusions support a causal interpretation, or only an association?
Do this for papers spanning the surveillance, outbreak, modeling, and risk-analysis domains too, not just the classic study-design topics. Because the specialty draws on a candidate's applied epidemiology experience, your own authored work and reports are also useful practice material: re-read them as a reviewer would.
Building Diplomate-Level Practice Questions
Public preparation material for this specific specialty is sparse. Several marketplace listings use the specialty's title, but visible previews include elementary recall questions, and at least one adjacent listing showed an inconsistent odds-ratio answer. Seller claims about "actual exam" content, "verified" answers, or guaranteed passing cannot be validated. Do not rely on them, and check every calculation yourself.
A better approach is to write or source questions that mirror the level of reasoning a diplomate should have:
- Calculation with interpretation: Compute a measure of association from a 2x2 table, then state what it does and does not tell you given the study design.
- Bias identification: Describe a study scenario and ask which bias is most likely and in which direction it shifts the estimate.
- Test interpretation: Give sensitivity, specificity, and prevalence, and require the predictive values, then ask how the answer changes in a different population.
- Applied judgment: Present an outbreak line list or surveillance summary and ask for the next investigative step.
Key Takeaway
If you can only explain an answer by recalling a definition, the question is too easy. Practice items should force you to compute, justify the method, and state the assumption you are relying on. For general practice resources, visit our main practice test site, and keep the base ACVPM and the specialty clearly separate in your mind.
A Domain-Sequenced Study Calendar
Because the application deadline for the posted cycle has passed, you likely have more than a few weeks. The sequence below is organized by domain dependency, so each block makes the next easier. Stretch each phase to fit your own timeline.
Foundations first
- Causality, Measuring Disease Frequency, and Measures of Association, because every later domain assumes fluency here.
- Rebuild 2x2 table calculations by hand until they are automatic.
Design and validity
- Epidemiologic Study Designs, Error and Confounding, and Data Acquisition, Organization, and Presentation.
- Appraise two or three recent papers per week against the design and bias checklist above.
Detection and response
- Diagnostic Tests, Epidemiologic Surveillance, and Outbreak Investigation.
- Work predictive-value problems across different prevalence levels and walk through outbreak steps on case scenarios.
Quantitative synthesis
- Risk Analysis, Infectious Disease Epidemiology/Modeling, and Biostatistics.
- Schedule these later because they lean on every earlier domain, but give them the most hands-on problem time.
Integration
- Mixed-domain sets and full-paper appraisals that cross several domains at once.
- Revisit your weakest domain, using the newest reference file as your checklist.

What Is Not Public (and How to Handle It)
Be candid with yourself about what cannot be verified. No current exact-specialty public candidate instructions were found establishing the number of questions, the exam duration, a numeric passing score, or a cohort pass rate. We therefore do not state any of these, and you should be skeptical of any vendor that does. Our pages on pass rate and passing score explain what can and cannot be said, and the difficulty guide discusses how to judge preparation without those numbers.
After You Pass: Fees, Dues, and Recertification
Passing triggers a USD 125 certification fee, followed by USD 50 annual specialty dues. Under the bylaws (amended October 2025), diplomates subject to recertification follow a ten-year cycle from initial specialty certification under Maintenance of Certification guidelines, and emeritus diplomates are exempt from annual fees.
Because the specialty builds on base ACVPM status, think of it as signaling advanced epidemiologic competence within preventive medicine. If you are weighing the investment, our analysis of whether the certification is worth it and the salary guide separate credential-specific evidence from occupation-wide data, since specialty-specific earnings figures are not published.
Frequently Asked Questions
No. The Epidemiology Specialty is a separate, subsequent certification for existing ACVPM diplomates. The main board exam has its own format, fees, and an epidemiology and biostatistics section that should not be confused with the specialty.
The September 2025 reference file lists 12 major knowledge domains, from Causality through Biostatistics. No percentage weights are published, so plan to prepare across all of them.
The posted amounts are USD 50 for application and examination combined, USD 125 for certification after passing, and USD 50 in annual specialty dues thereafter.
The posted exam date is June 8, 2027, and the posted application deadline was October 5, 2026, which has passed. Confirm any future cycle directly with the issuer rather than assuming an extension.
Normally coauthorship of a peer-reviewed article within five years. A manuscript submitted within the prior 12 months or a major epidemiologic report documenting substantial analysis can be considered alternatives, along with at least three dated reference letters.
Work the twelve domains deliberately, appraise real research, and verify every calculation yourself. For broader study resources, return to the practice test hub or revisit the full study guide as your preparation progresses.
