- The DACVCP requires passing both Phase I (200 multiple-choice questions) and Phase II (ten written and mixed-format question groups worth 200 points).
- The published 2026 administration was remote via ExamSoft: Phase I on May 19, Phase II on June 30.
- Domains 1-22 come from a December 2021 Phase I blueprint; Domains 23-26 are Phase II's four subject categories.
- Phase II requires two peer-reviewed papers accepted or published by February 1 of the examination year.
The Two-Phase Reality of the ACVCP Pathway
Preparing for the Diplomate, American College of Veterinary Clinical Pharmacology credential is unlike preparing for most professional exams. There is no single sitting, no consumer-facing question bank, and no commercially published outline you can simply memorize. The American College of Veterinary Clinical Pharmacology (ACVCP) administers a two-phase process, and a first-attempt pass depends on understanding how the two phases differ in what they reward.
Phase I is a 200-question multiple-choice examination anchored in the foundational science of veterinary clinical pharmacology and the pharmacology of organ systems and drug classes. Phase II is a different animal: ten question groups that combine written responses, multiple choice, fill-in-the-blank and extended matching, scored out of 200 points. Phase I tests whether you hold the knowledge. Phase II tests whether you can apply it, defend it in writing and reason through experimental design, therapeutics and regulation.
If you are still orienting yourself to the credential itself, our explainers on what DACVCP is and DACVCP requirements and eligibility cover the basics. This guide assumes you are in or approaching an approved residency and want to turn that training into a passing result.
Exam Format, Delivery and Logistics
Knowing the mechanics removes avoidable stress. The published 2026 cycle ran as follows, and while those dates have passed, the format is the best available guide to what to expect. A 2027 schedule was not verified at the time of writing, so confirm current dates directly with the ACVCP; our DACVCP exam dates and deadlines guide tracks scheduling details.
| Feature | Phase I | Phase II |
|---|---|---|
| 2026 date | May 19 | June 30 |
| Delivery | Remote, ExamSoft | Remote, ExamSoft |
| Content | 200 multiple-choice questions | Ten question groups worth 200 points |
| Question styles | Multiple choice | Written response, multiple choice, fill-in-the-blank, extended matching |
| Sessions | Two sessions of 100 questions | Two sessions of 100 points each |
| Ordinary schedule | 08:00-12:00 and 14:00-18:00 local time | Eight active hours |
Two details deserve emphasis. First, Phase II's 200 points are not 200 questions. A single written-response group can carry substantial weight, so time allocation within each session matters more than a simple per-question pace. Second, the eight active hours of each phase exclude the break, meaning the endurance demand is real: you are reasoning at a high level across two four-hour blocks.
Candidates provide their own compatible Windows or Mac laptop running Examplify with administrator privileges. The encrypted exam is downloaded in advance and unlocked with a proctor password. Once in examination mode, the software blocks internet access, files and other applications. The ACVCP offers advance practice examinations specifically so candidates can rehearse the software and become familiar with question structure. Use them early, not the night before.
Reading the Blueprint Honestly
The single most important thing to understand about DACVCP content is how the 26 domain headings are sourced, because it shapes how you should use them.
- Domains 1-22 are the headings from the Suggested Blueprint for the Phase I examination, last revised December 2021. They are dated preparation-curriculum topics, not a verified current or exhaustive exam outline.
- Domains 23-26 are the four examination subject categories listed on the current Phase II Examination page. The ACVCP does not publish category percentages there.
- The count of 26 is simply a count of these supplied headings. It is not an official combined exam-domain count.
Equally important: no domain weights are published in the sources used here, so this guide does not assign percentages. A separately indexed Phase II blueprint from December 2021 contains historical question allocations, but those should not be treated as current weighting, particularly because the present Phase II format is ten groups worth 200 points. For a deeper walk through each heading, see our complete guide to all 26 DACVCP content areas.
Core Pharmacology Science: Domains 1-9
The first nine headings form the scientific spine of the discipline. Every later organ-system question assumes fluency here, so treat these as non-negotiable foundations rather than a warm-up.
Domains 1-2: Physiochemical Characteristics and Pharmacodynamics
The blueprint spells it "Physiochemical," and the first heading concerns active pharmaceutical ingredients. Expect to reason from molecular properties to behavior in the body.
- Ionization, pKa, lipophilicity and solubility, and how they predict absorption and distribution
- Receptor theory, agonism and antagonism, potency versus efficacy, and dose-response relationships
- Mechanisms of drug action that explain why a drug works in one species and fails in another
Domains 3-5: Drug Movement, Pharmacokinetics and Modifying Factors
This cluster is where quantitative skill is rewarded. Drug movement (membrane transport, transporters, barriers) feeds directly into pharmacokinetic modeling.
- Compartmental and noncompartmental analysis, clearance, volume of distribution, half-life and bioavailability
- Metabolism and excretion, including interspecies differences that make extrapolation hazardous
- Factors impacting movement or response: age, disease, genetics, breed, drug interactions and formulation
Domains 6-9: Routes, Dosing Forms, Adverse Events and Therapeutic Failure
These headings connect pharmacology to practice and to Phase II-style reasoning.
- Route-specific absorption and the trade-offs between oral, parenteral, topical and other routes
- Dosing forms and relevant drug delivery devices, including how formulation changes performance
- Adverse event mechanisms, recognition and mitigation
- Causes for therapeutic failure: wrong dose, poor bioavailability, resistance, interactions, compliance and misdiagnosis
A practical note: Domains 4 and 24 (Pharmacokinetics and Therapeutic Drug Monitoring) overlap conceptually. Candidates who build strong pharmacokinetic fundamentals for Phase I carry that investment straight into Phase II, so this is the best return on early study hours. If you want a sense of how demanding this material feels, see how hard the DACVCP exam is.
Organ Systems and Drug Classes: Domains 10-22
The middle thirteen headings shift from principles to applications. Here the volume of material is the challenge: a clinical pharmacologist is expected to speak authoritatively about drugs across every body system and therapeutic class.
Domains 10-16: Organ-System Pharmacology
Systems covered are Nervous System, Renal, Cardiovascular, Gastrointestinal, Reproduction, Endocrine, and General and special senses.
- Anesthetic, analgesic, sedative and anticonvulsant pharmacology within the nervous system
- Diuretics and renal handling of drugs, including dose adjustment in renal impairment
- Antiarrhythmics, vasodilators and inotropes in the cardiovascular domain
- Antiemetics, gastroprotectants, motility agents and the gut's role in oral drug absorption
- Reproductive hormones and their species-specific uses and risks
- Endocrine therapeutics, from diabetes management to thyroid and adrenal disease
- Ophthalmic and otic drug delivery as the typical "special senses" topics
Domains 17-22: Therapeutic Classes
These headings cover Control of inflammation/immunomodulation, Anticancer drugs, Fluid therapy, Anti-infectives, Botanical/Herbals, and Disinfectants/antiseptics.
- NSAID, corticosteroid and immunomodulator mechanisms, selectivity and toxicity
- Cytotoxic and targeted anticancer agents, including resistance and safety considerations
- Crystalloids, colloids and electrolyte therapy, with attention to physiology-driven choices
- Antimicrobial classes, pharmacokinetic/pharmacodynamic targets, resistance and stewardship
- Botanical and herbal products, where evidence quality and regulatory status vary widely
- Disinfectant and antiseptic chemistry, spectrum of activity and appropriate use
Key Takeaway
Anti-infectives and organ-system drugs reward comparison thinking. Build side-by-side tables within each class, covering mechanism, species differences, key adverse effects and dosing adjustments, rather than memorizing drugs one at a time.
Phase II Subject Categories: Domains 23-26
The current Phase II Examination page lists four subject categories: Therapeutics, Pharmacokinetics and Therapeutic Drug Monitoring, Experimental Design, Statistics and Analytical Methods, and Regulatory Pharmacology. These carry the Phase II philosophy. You are no longer just recalling facts; you are being asked to behave like a Diplomate.
Domain 23: Therapeutics
Expect case-driven reasoning that integrates the mechanistic knowledge from Phase I into patient-level decisions.
- Selecting, dosing and adjusting therapy for a specific patient and species
- Weighing evidence, risk and alternatives, and justifying the choice in writing
Domain 24: Pharmacokinetics and Therapeutic Drug Monitoring
Phase II pushes beyond textbook definitions into interpretation and calculation.
- Designing and interpreting sampling strategies and monitoring plans
- Using measured concentrations to refine dosing regimens
Domain 25: Experimental Design, Statistics and Analytical Methods
This is where the peer-reviewed publication requirement becomes relevant. Candidates who have genuinely authored research tend to have an advantage here.
- Study design, controls, bias and sample-size reasoning
- Appropriate statistical tests and critical appraisal of published work
- Analytical method validation and assay performance
Domain 26: Regulatory Pharmacology
A distinctive feature of the specialty. Study how drugs move from development to approval and use in veterinary medicine.
- Approval pathways, labeling and extralabel considerations
- Compounding, residues and food-animal implications as they arise in practice
Because the sources do not publish current percentages for these four categories, avoid over-investing in any one on the assumption that it is "heavier." Balanced preparation is safer than a guess.
Fees, Deadlines and Eligibility Mechanics
The administrative path has its own failure points. Missing a deadline or a credential requirement can cost a year, so treat these as seriously as the science. Our DACVCP certification cost breakdown expands on the figures below.
| Item | Published 2026-cycle amount |
|---|---|
| Phase I application | USD 75 |
| Phase I examination | USD 200 |
| Phase II credentials review | USD 250 |
| Phase II examination | USD 300 |
Retakes require the respective examination fee. The general fee page allows refunds only for extenuating circumstances accepted by the Board, while the phase pages describe examination fees as nonrefundable, so budget on the assumption that fees are not recoverable. The Becoming a Resident page separately describes USD 75 as a first-year candidate registration fee; the public pages do not make clear whether this is the same as, or additional to, the Phase I application charge, so confirm with the ACVCP before budgeting.
Phase I Eligibility
Applicants must be legally qualified to practice veterinary medicine and enrolled in, or have completed, approved ACVCP residency training. The application requires two references.
Phase II Credentials
Phase II requires completed approved training, a Phase I pass, approved credentials, course documentation and transcripts, and two peer-reviewed papers accepted or published by February 1 of the examination year. At least one paper must be original veterinary clinical pharmacology research; the other may be original research or an eligible evidence-based systematic review or meta-analysis. First authorship is required on at least one paper. Neither paper may have been used for another specialty board, and publication must not predate the beginning of training by more than two years.
Applications are ordinarily due October 1 before the examination year, with intent to sit due February 1. The currently dated checklist covers October 1, 2025 and February 1, 2026. Full details are in our DACVCP requirements guide.
On the question of what comes after certification, the ACVCP has a Maintenance of Certification committee that administers recertification. Historical bylaws from June 2018 describe periodic review of maintenance records, but their current applicability is unverified, and no current renewal hours, fees or interval should be assumed. Check with the college for the live requirements.
A Domain-Driven Sequencing Plan
Because Phase I and Phase II reward different skills, sequence your preparation around the content rather than around a generic calendar. The outline below ties each block to specific domains and explains the logic. Adjust the pacing to your residency and publication timeline.
Foundations first (Domains 1-5)
- Rebuild physicochemical and pharmacodynamic fundamentals before anything else
- Work pharmacokinetic problems by hand; this skill compounds into Domain 24
- Take an ACVCP practice examination to learn the software and question structure
Delivery and failure modes (Domains 6-9)
- Connect routes and dosing forms to bioavailability and device considerations
- Catalog adverse event mechanisms and causes of therapeutic failure by drug class
Organ systems (Domains 10-16)
- Study one system at a time, building comparison tables across species
- Pair each drug group with its key adverse effects and dose adjustments
Therapeutic classes (Domains 17-22)
- Prioritize anti-infectives and anticancer drugs, which carry the densest detail
- Do not skip botanicals and disinfectants; they are easy points for those who prepare
Phase II reasoning (Domains 23-26)
- Practice written answers under time pressure, since the format includes written responses
- Review your own published work critically for experimental design and statistics
- Read regulatory material on approval, labeling and extralabel use
Spaced review fits naturally here: revisit Domains 1-5 in every later block, because pharmacokinetic and pharmacodynamic reasoning underlies nearly every organ-system and Phase II question. Use our DACVCP cheat sheet for quick-reference review as the exam approaches.
Software Rehearsal and Exam-Day Readiness
Remote delivery shifts some risks from travel and testing centers to your own equipment and environment. Reduce those risks deliberately.
- Verify your laptop meets the Examplify compatibility requirements and that you have administrator privileges well before exam week.
- Download the encrypted exam as soon as it is available, since the proctor password is only released at the appropriate time.
- Use the practice examinations to confirm everything works, including how question types display.
- Plan the break in the middle of each day: eight active hours demand stamina, so eat, rest and reset between sessions.
- Manage Phase II time by group, not by guesswork, because written-response groups can carry significant points.
When you are ready to test yourself on realistic question styles, our practice test platform offers timed practice you can build into your final weeks. For context on outcomes, see what we can and cannot say in our DACVCP pass rate analysis and passing score guide: a fixed numerical pass mark and a current pass rate were not verified, since passing points are recommended by the Examination Committee and ad hoc reviewers for Board approval.
Frequently Asked Questions
Yes. The complete credential requires both phases. Phase I is a 200-question multiple-choice exam, and Phase II is a ten-group examination worth 200 points. A Phase I pass is also a prerequisite for the Phase II credentials review.
Not exactly. Domains 1-22 come from a December 2021 Phase I preparation blueprint, and Domains 23-26 are the four Phase II subject categories. No current percentages are published, so treat them as a study framework and confirm against current ACVCP materials.
A fixed numerical pass mark was not verified. Passing points are recommended by the Examination Committee and ad hoc reviewers for Board approval. See our DACVCP passing score guide for what is and is not known.
Both phases must be passed within a five-year eligibility period starting with the first eligible examination year after Phase I approval. The issuer's example is approval in December 2025 permitting examinations from 2026 to 2030.
That depends on your career goals, since the specialty is small and highly specialized. Our DACVCP ROI analysis and salary guide discuss the trade-offs qualitatively, without invented figures.
