DACVS Cheat Sheet 2026: One-Page Review of Must-Know Facts

What This Credential Actually Is

This cheat sheet covers the Diplomate, American College of Veterinary Surgeons credential, specifically its Phase I Surgical Knowledge Examination administered by the American College of Veterinary Surgeons (ACVS). Phase I is one requirement on the road to DACVS. Passing it does not, by itself, award the Diplomate title. If you want the broader definition first, see What Is DACVS? or What Does DACVS Stand For?.

The examination retains two forms: small animal and large animal. Small Animal covers domestic canine, feline and non-species-specific content. Large Animal covers equine, food animal, small ruminant, camelid and non-species-specific content. Choose your form deliberately and study the blueprint for that form only, because the knowledge-area weights differ between the two.

Exam Format at a Glance

Note that the seven hours is the published examination period, not a separately inferred appointment length. Because you cannot go back to part one once the break begins, treat the end of part one as a hard commit. Use any remaining time in that part to revisit flagged items before you leave it.

Questions are single-best-answer, so several options may look plausible. The skill being tested is choosing the most defensible answer from fundamentals, not recalling an obscure fact. For a realistic read on difficulty, see How Hard Is the DACVS Exam?.

The Four Official Disciplines

The blueprint organizes content into four main disciplines. These are official examination disciplines, not preparation-curriculum headings, and the blueprint does not print aggregate percentages for them. Weights are published only at the knowledge-area level, separately for each animal form. For a fuller walk-through, read DACVS Exam Domains: Complete Guide to All 4 Content Areas.

Small-Animal Knowledge-Area Weights

These are the published small-animal weights. The entries total 98% as printed; do not rescale them or try to derive discipline-level percentages.

Large-Animal Knowledge-Area Weights

The large-animal entries total 100% as printed. Again, these weights belong to knowledge areas, not to the four disciplines as a whole.

What Phase I Does and Does Not Test

Phase I addresses surgical fundamentals and basic science. According to the current Examination FAQ, clinical diseases and their specific treatment are excluded. This is the single most useful scoping fact for avoiding wasted study time: you are preparing for science, pharmacology, anesthesia and technique, not for disease-by-disease case management.

Equally important, do not substitute Phase II material for Phase I preparation. The journal-review and specific surgical-procedure requirements of Phase II belong to a different examination and should not drive your Phase I outline. Build your plan from the published Phase I blueprint and the Phase I Examination Reading List, and cross-check with the Examination FAQ. For a structured approach, see the DACVS Study Guide: How to Pass on Your First Attempt.

2027 Fee, Dates and Registration Mechanics

Note the gap between the registration deadline and the payment deadline: registering by October 30 does not mean payment is due then. The payment date is January 8, 2027. Confirm every figure against the 2027 Phase I Surgical Knowledge Examination Information Pamphlet (September 2026) before acting, since ACVS publishes the authoritative logistics. For scheduling planning, see DACVS Exam Dates: Testing Windows, Deadlines & Scheduling, and for the wider financial picture, DACVS Certification Cost: Complete Pricing Breakdown.

Test-Day Rules That Trip Candidates Up

• No aids of any kind. Information aids, books, notes and phones are prohibited.
• Stay on site. Candidates remain at the test center during breaks and cannot access phones, notes or study materials.
• The clock matters. The scheduled break of up to one hour stops the clock; unscheduled breaks do not.
• One-way door. After the break you cannot return to the first part.
• Scratch work. Laminated note paper is provided, so practice working problems without relying on your own materials.

Eligibility and the Residency Clock

To sit Phase I you must be an ACVS resident in good standing, without applicable probation or sanctions, with an adviser attestation and your own training/study-readiness attestation submitted in CERT. Residents may sit at any time during residency, optimally in the second year, and must pass within six years of starting residency.

Entry to the training pathway requires veterinary qualification and a twelve-month rotating internship or equivalent experience. Full DACVS certification additionally requires:

• Completion of at least a three-year/156-week approved residency, including 110 weeks of surgical training
• An accepted scientific publication
• Approved credentials
• Passing both Phase I and Phase II

Those full-credential items are not prerequisites to sitting Phase I during residency. For a deeper look, see DACVS Requirements: Eligibility, Prerequisites & How to Qualify, and for the training side, DACVS Training.

Scoring, Results and Unknowns

The passing standard is criterion-referenced, set by experts and equated across years. It cannot be raised after the examination. Results are ordinarily released in four to six weeks.

Two things have not been verified, and you should be wary of anyone who claims otherwise: a fixed numerical pass mark, and a current issuer-wide Phase I pass rate. A published 2017-2021 small-animal residency-program survey exists, but it is historical research rather than a current cohort rate. The honest framing is that the standard is competence-based and not a published percentage. See DACVS Passing Score: Exactly What You Need to Pass and DACVS Pass Rate: What the Data Shows for how to interpret what is and is not known.

After Certification: Maintenance Basics

Maintenance applies to the full Diplomate credential after certification is complete, not to Phase I itself. For Diplomates certified in 2016 or later, the initial certificate expires on the sixth December 31 after the examination, and subsequent cycles last five years.

• Maintenance of Certification (MOC) requires 100 qualifying activity points.
• At least 70 of those points must fall within your certified animal specialty (small animal surgery or large animal surgery).
• You must maintain good standing and submit through CERT by November 1 of the expiry year.
• The current MOC page specifies no submission fee.

Sequencing Your Prep by Domain

Rather than generic scheduling, tie your order of study to the blueprint. Start with Basic Science, since Anatomy, Physiology and Pathobiology together make up the biggest block of both forms, and later domains lean on that vocabulary. Then layer Pharmacology and Anesthesia, which reinforce each other through shared drug classes. Finish with Surgical Methods, where tissue handling, healing, aseptic technique and implants are best consolidated alongside timed practice.

Use the DACVS practice tests to rehearse single-best-answer reasoning, and revisit weak knowledge areas against the blueprint weights. You can also start a timed practice session to build stamina for the seven-hour format.
