DACVO Pass Rate 2026: What the Data Shows

What the Published Numbers Say

Pass-rate searches for the Diplomate, American College of Veterinary Ophthalmologists (DACVO) credential tend to return vague claims. The real answer comes from one place: the annual credentialing reports published by the American Board of Veterinary Ophthalmology (ABVO), which administers certification examinations for the American College of Veterinary Ophthalmologists (ACVO). This article sticks to what those reports actually state and flags what they do not.

The most recent report, the ABVO Annual Credentialing Report - Fall 2026 (dated October 1, 2026), reports that 21 candidates completed certification among 49 who participated in some portion of the examination. That is a combined completion rate of 42.9%. Split by experience, first-time candidates completed at 50% and repeat candidates at 33.3%.

If you want the broader picture of how those numbers relate to difficulty, see our companion piece How Hard Is the DACVO Exam? Complete Difficulty Guide 2026, and for the cut-score mechanics, DACVO Passing Score 2026: Exactly What You Need to Pass.

Fall 2025 vs. Fall 2026: Two Reports, Two Pictures

The prior year's report, the ABVO Annual Credentialing Report - Fall 2025 (October 10, 2025), is retained here as historical evidence. It published a combined rate of 63.8%, with first-time candidates at 61.8% and repeat candidates at 66.7%. It also broke results out by component.

Two cautions apply. First, the Fall 2025 overall denominator does not reconcile to a clean integer pass count, so those percentages should be read as reported historical figures, not rebuilt into candidate counts. Second, the Fall 2026 MC row contains an inconsistent pairing of candidate count and percentage, so no component pass count should be reconstructed from it. The Fall 2025 component rates are useful context, but they are not a substitute for 2026 component results.

Why a Completion Rate Is Not a Part Pass Rate

The difference between a part pass rate and a completion rate explains why the 2025 component percentages (all in the high 70s to low 80s) sit alongside a combined rate of 63.8%. A candidate can pass three of four parts and still not be counted as having completed certification. Because all four assessed parts must be passed, small shortfalls in individual parts compound at the whole-credential level.

Candidates are also not limited to a single sitting for everything. Only unsuccessful parts are repeated, which is why the "repeat candidate" category exists in the reports at all. For the full eligibility timeline around repeat attempts, see DACVO Requirements 2026: Eligibility, Prerequisites & How to Qualify.

The Four Gates: Where Candidates Actually Fail

The March 3, 2026 ABVO Policies and Procedures identify four assessed parts. Understanding the format of each tells you why different kinds of preparation matter.

The 2025 component rates suggest IR (78.7%) and extraocular surgery (77.8%) were the two parts with the lowest reported rates that year, while MC (82.6%) and intraocular (83.3%) were slightly higher. Differences of a few points on small cohorts are not strong evidence that one part is inherently harder, so treat that ordering as a hint rather than a rule.

Reading the MC Blueprint Against the Data

The Exam Specification Blueprint (the linked file is named ACVO blueprint 2020, with no newer printed revision date) organizes the 250 MC questions by species. These are examination blueprint headings, not a preparation curriculum, and the percentages apply only to the MC section, not to the whole certification.

Within canine, feline and equine content, the blueprint nests regions (Adnexa, Anterior Segment, Posterior Segment), subdivisions (Cornea, Iris/CB, Glaucoma, Lens), and tasks (Examination, Assessment, Treatment Planning). Those within-species anatomical percentages must not be treated as whole-examination weights. For a domain-by-domain walkthrough, see DACVO Exam Domains 2026: Complete Guide to All 5 Content Areas.

Who Is Actually in the Denominator

Candidates reach the examination only after meeting demanding prerequisites under the March 3, 2026 Policies and Procedures: a veterinary degree, licensure in good standing or an applicable institutional exemption, at least 12 months of full-time clinical practice before residency, and an approved residency of at least 36 months. That residency must include 104 weeks (520 days) of clinical ophthalmology training, with at least 80% under direct supervision. Training also includes 12 hours of histopathology annually and two hours of literature review monthly.

This matters for interpreting the pass data. The people sitting the examination are not a general population; they are residency-trained veterinarians who have already been screened through logs, evaluations and Supervising Diplomate documentation. A completion rate of 42.9% among that pre-selected group is a statement about the exam's rigor, not about the general ability of the candidates. Our DACVO Training overview and DACVO Study Guide 2026: How to Pass on Your First Attempt cover how residents typically structure that preparation.

There is also a limit on how long a candidate has to complete the process. Section 5.11 of the policies gives five consecutive examination offerings after residency completion, while the credentials section describes five consecutive years. That wording difference is retained in the source documents, so confirm the current interpretation with ABVO before relying on either phrasing in your planning.

What the Data Cannot Tell You

The reports are valuable, but they leave several questions open. Being explicit about these gaps is more useful than guessing.

• No stable multi-year trend. The 63.8% (Fall 2025) and 42.9% (Fall 2026) figures come from different cohorts of modest size. With 49 participating candidates in the latest cycle, a swing of a few people moves the percentage substantially. Do not read the difference as a permanent decline.
• No reconstructed component counts for 2026. The MC row in the Fall 2026 report has an inconsistent candidate-count and percentage pairing, so it is not used to derive a part-level pass count.
• No cut score disclosure. MC and IR passing points are set using Angoff and Hofstee procedures, which means they are criterion-based and not a fixed percent-correct. The practical rubrics state a passing point of 70. Details are explained in DACVO Passing Score 2026.
• No reason codes for failure. The published figures do not say why candidates did not complete: content gaps, time management, surgical technique, or logistics.
• No guidance on fee changes. The Fall 2026 report announces fee restructuring beginning in 2027, so the 2026 fees remain explicitly 2026 figures.

Using the Data to Plan Your Attempt

The data supports a few concrete planning conclusions without overstating them.

Treat each part as its own project

Because only failed parts are repeated, each of the four assessed parts deserves distinct preparation. Written parts (IR and MC) are delivered through ExamSoft/Examplify at candidate-selected, approved remote locations with local in-person proctors, so you need a compatible laptop and should complete the software practice examination, which is explicitly not representative of examination content. The practicals are hands-on in Gainesville and depend on rehearsed technique with your own instruments.

Weigh the first-attempt advantage

In the Fall 2026 report, first-time candidates (50%) outperformed repeat candidates (33.3%). In Fall 2025 the pattern was reversed (61.8% first-time vs. 66.7% repeat). The sign flips between years, which is a good reminder not to over-interpret small cohorts. The practical takeaway is modest: arrive prepared for all four parts at your first sitting rather than planning around a retake.

One short, DACVO-specific sequencing idea

If you must sequence your last months, anchor the schedule to the exam's structure rather than to generic habits:

Factor in cost and long-term value

Published 2026 fees were USD 750 per assessed part, USD 3,000 for all four, plus a separate USD 100 Certifying Examination Application fee (the Provisional Resident Application is a separate USD 150 charge). Because failed parts must be retaken, a partial pass changes your total spend, which is one more reason the part-by-part framing matters.

Remember what comes after

Maintenance of certification is mandatory for Diplomates first certified in 2015 or later, requiring at least 300 approved, verifiable MOC credits every five years and professional good standing. Credits span education, scholarship, service and rounds and must not be equated with 300 CE contact hours. Earlier Diplomates may participate voluntarily. The Fall 2026 report describes a future attestation-and-audit process, with details still being finalized.
