- The issuer's September 2025 reference file lists exactly 12 major knowledge domains and publishes no percentage weights.
- Posted costs: USD 50 application and exam, USD 125 certification fee after passing, then USD 50 annual dues.
- The posted exam date is June 8, 2027; the application deadline of October 5, 2026 has already passed.
What This Cheat Sheet Covers (and What It Doesn't)
This page condenses the verified, issuer-sourced facts about the Diplomate of the ACVPM - Epidemiology Certification into a single reviewable layout. The certifying body is the American College of Veterinary Preventive Medicine (ACVPM), through its Epidemiology Specialty (ACVPM-ES), and the specialty Examination Committee establishes the certifying examination.
One distinction matters before anything else: this is a subsequent specialty certification for people who already hold ACVPM diplomate status. It is separate from the initial ACVPM board examination and that exam's Epidemiology and Biostatistics section. Study material, timing, fees, and pass-rate claims for the main board do not transfer to the specialty. If you want the broader orientation first, start with What Is DACVPM (Epidemiology)? or the overview at DACVPM (Epidemiology) Certification.

The current September 2025 reference file supersedes the older October 2024 "Major Knowledge Areas" document, which grouped the content differently. Do not merge the two lists to create extra domains; the current list of 12 is the one to study against.
Eligibility at a Glance
Eligibility is built around demonstrated epidemiology experience, not just ACVPM standing. The key elements:
- Standing: ACVPM diplomate in good standing.
- Experience: at least two years of epidemiology experience within the five years before application, including qualifying epidemiology-focused residency or graduate study.
- Competency evidence: normally coauthorship of a peer-reviewed scientific article within five years.
- Accepted alternatives: 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.
- References: at least three letters, dated within one year of application, from ACVPM diplomates or other epidemiologists. When training counts toward your experience, at least one referee must have been responsible for a significant portion of that training.
Fees, Dates, and the Posted Exam Cycle
| Charge or Milestone | Amount / Date | When It Applies |
|---|---|---|
| Application and examination (combined) | USD 50 | At application |
| Certification fee | USD 125 | After passing |
| Annual specialty dues | USD 50 | Annually thereafter |
| Application deadline | October 5, 2026 | Already past on the verification date |
| Examination | June 8, 2027 | Posted exam date |
Two cautions. First, the issuer's indexed page still describes the application period as open, but its explicit deadline of October 5, 2026 is the date to rely on; no extension should be assumed. Second, the application portal requires ACVPM diplomate access, so confirm current status and any updates directly with the college. For a cost-by-cost discussion, see DACVPM (Epidemiology) Certification Cost 2026, and for scheduling detail see DACVPM (Epidemiology) Exam Dates 2026.
The 12 Official Knowledge Domains
These are the issuer's major examination knowledge domains, reproduced here by name. They are exam content areas, not editorial allocations, and no weights are published, so avoid any resource that claims to tell you "X percent of the exam is Domain Y."

- 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

- Infectious Disease Epidemiology/Modeling
- Biostatistics
A deeper domain-by-domain walkthrough is available in DACVPM (Epidemiology) Exam Domains 2026: Complete Guide to All 12 Content Areas.
Must-Know Formulas and Concepts by Domain
Because the credential is for existing diplomates, expect the specialty to probe interpretation and application rather than rote definitions. The points below are standard epidemiologic content tied to each official domain; they are not a claim about specific exam questions.
Causality
Be able to reason from association to causal inference and defend the reasoning.
- Bradford Hill considerations and their limits as a checklist
- Counterfactual and component-cause thinking (sufficient and necessary causes)
- Temporality as the one essential criterion
Measuring Disease Frequency
Distinguish the measures cleanly and know when each is appropriate.
- Prevalence versus incidence (cumulative incidence and incidence rate)
- Person-time denominators and the prevalence-incidence-duration relationship
- Crude, specific, and standardized (direct and indirect) rates
Measures of Association
Calculate, then interpret in context.
- Risk ratio, rate ratio, odds ratio, and when the odds ratio approximates the risk ratio
- Risk difference, attributable fraction, population attributable fraction, number needed to treat
- Check your arithmetic: public sources show answer keys with inconsistent odds-ratio results, so always recompute
Data Acquisition, Organization, and Presentation
Know how data are collected, structured, and displayed responsibly.
- Data sources, coding, and quality checks
- Choosing graphs and tables that match the data type (epidemic curves, histograms, maps)
- Spotting misleading presentation
Epidemiologic Study Designs
Match question to design and name each design's characteristic biases.
- Cross-sectional, case-control, cohort, and experimental designs, including clinical trials
- Strengths, weaknesses, and appropriate measures of association for each
- Sampling approaches and sample-size reasoning
Risk Analysis
Understand the structured framework used for animal-health and public-health decisions.
- Components of risk assessment, risk management, and risk communication
- Qualitative versus quantitative assessment and the role of uncertainty
Error and Confounding
This is where design and analysis meet.
- Random versus systematic error; selection, information, and confounding bias
- Effect modification versus confounding
- Control strategies: restriction, matching, stratification, multivariable adjustment
Conceptual Understanding, Interpretation/Application of Diagnostic Tests
Move fluidly between test characteristics and decisions.
- Sensitivity, specificity, predictive values, and likelihood ratios
- How prevalence changes predictive values
- Serial versus parallel interpretation and herd-level versus individual-level testing
Epidemiologic Surveillance
Know the purpose, design, and evaluation of surveillance systems.
- Passive versus active surveillance; sentinel and syndromic approaches
- Attributes for evaluation: sensitivity, timeliness, representativeness
- Detecting aberrations against a baseline
Outbreak Investigation
Think in the order a field investigation actually unfolds.
- Confirming the outbreak, defining cases, and descriptive epidemiology by time, place, and animal or person
- Hypothesis generation, analytic study selection, and control measures
- Reading an epidemic curve to infer source type and incubation
Infectious Disease Epidemiology/Modeling
Be fluent with transmission concepts and basic model logic.
- Basic and effective reproduction numbers and what drives them
- Compartmental model structure and herd-immunity reasoning
- Incubation, latent, and infectious periods; modes of transmission
Biostatistics
Interpret output as a working epidemiologist would.
- Confidence intervals versus p-values; power and sample size
- Regression families (linear, logistic, Poisson, survival) and their assumptions
- Choosing and critiquing tests for the data type
Critical Appraisal: The Skill Behind the Reference List
The current reference document recommends the latest available editions of listed books and critical appraisal of recent peer-reviewed epidemiologic research across the knowledge domains. It also states that its suggested books, journals, and online resources are non-exhaustive. In practice, that means the list is a starting point, not a boundary.
Key Takeaway
Practice reading one recent epidemiologic paper per domain and writing down its design, main bias threats, measure of association, and what you would change. Appraisal across all 12 domains is explicitly part of the issuer's recommendation, so it deserves dedicated study time rather than leftover hours.
A workable appraisal routine for each paper: identify the question and design, check how exposure and outcome were measured, look for confounding and selection problems, recompute at least one measure from the reported counts, and decide whether the conclusion follows from the data. This habit trains several domains at once, especially Error and Confounding, Measures of Association, and Biostatistics. For a full plan, see the DACVPM (Epidemiology) Study Guide.
Sequencing the Domains in a Study Calendar
Since no weights are published, sequence by dependency rather than by assumed importance. Foundational measurement and association concepts feed nearly everything else, so they come first.
Foundations
- Measuring Disease Frequency and Measures of Association: recompute every formula by hand
- Causality: connect each concept to a real study you have read
Design, Bias, and Tools
- Epidemiologic Study Designs, then Error and Confounding while designs are fresh
- Data Acquisition, Organization, and Presentation alongside Biostatistics
- Diagnostic tests: work prevalence-shift problems until automatic
Applied Domains
- Surveillance, Outbreak Investigation, and Infectious Disease Modeling as integrated scenarios
- Risk Analysis as a framework applied to those scenarios
- Full-domain appraisal practice using recent papers

After Passing: Fees, Dues, and Recertification
- Certification fee: USD 125 once you pass.
- Annual specialty dues: USD 50 per year thereafter.
- Emeritus status: the bylaws exempt emeritus diplomates from annual fees.
- Recertification: diplomates subject to recertification follow a ten-year cycle from initial specialty certification under Maintenance of Certification guidelines.
The governing document is the bylaws for the ACVPM Epidemiology Specialty, amended October 2025. For career context, who employs diplomates and how occupations are paid, see DACVPM (Epidemiology) Jobs and the salary guide. Keep in mind that available salary data generally describes occupations such as veterinary epidemiologist rather than this specific credential, so credential-specific earnings claims should be treated cautiously. The broader value question is covered in Is the DACVPM (Epidemiology) Certification Worth It?.
What Is Not Published (Don't Guess)
No current exact-specialty public candidate instructions were verified for the following, so they are deliberately omitted here:
- Number of exam questions
- Exam duration
- Numeric passing score
- Cohort pass rate
Any site stating these as fact for the specialty is either importing main-board information or making an unvalidated claim. Likewise, marketplace listings that promise "actual exam" questions, "verified" answers, or guaranteed passing are unvalidated. Where you need the topic discussed qualitatively, see DACVPM (Epidemiology) Passing Score and DACVPM (Epidemiology) Pass Rate, and confirm any specifics directly with the ACVPM.
FAQ
Only ACVPM diplomates in good standing may apply. They must also show at least two years of epidemiology experience within the five years before application, typically with coauthorship of a peer-reviewed article within five years, plus at least three dated reference letters.
The posted amounts are USD 50 for the combined application and examination, USD 125 for the certification fee after passing, and USD 50 in annual specialty dues thereafter. Emeritus diplomates are exempt from annual fees under the bylaws.
The posted exam date is June 8, 2027. The posted application deadline was October 5, 2026, which had already passed on the verification date, and no extension should be assumed. Check with the ACVPM for the next cycle.
No. The issuer's September 2025 reference file lists 12 major knowledge domains but assigns no percentages, so any resource quoting weights is not reflecting official data.
No. The specialty is a subsequent certification for existing ACVPM diplomates and is separate from the initial board examination and its Epidemiology and Biostatistics section. Format, timing, fees, and pass-rate information for the main board should not be applied to the specialty.
