American College of Veterinary Pathologists (ACVP): How to Become Board-Certified

ACVP certifies veterinarians in veterinary anatomic pathology and veterinary clinical pathology, the two specialties AVMA lists under the college, and the certifying process is a two-phase examination whose credential is Diplomate of the ACVP, in veterinary anatomic or clinical pathology.

Phase II is taken in a single discipline: a candidate trains and tests in veterinary anatomic pathology or in veterinary clinical pathology.

AVMA counts 3,347 active ACVP Diplomates as of December 31, 2025, listing 2,642 under anatomic pathology and 705 under clinical pathology.

Those two figures add up exactly to the college total, so AVMA's table is a complete split of the field, with anatomic pathology the larger side by AVMA's own count.

ACVP's stated prerequisite is the veterinary degree itself: candidates must hold a veterinary degree from a North American AVMA-accredited college or an international AVMA-listed veterinary college.

The training requirements after that are measured in months of veterinary pathology training.

The first gate is 12 months of in-person veterinary pathology training, completed before the Phase I Examination date.

The Phase II gate sits deeper: 36 months of training on the Standard Route, or 48 months on the Alternate Route, completed before the Phase II Examination date.

Both gates run to examination dates, so the count that matters is training completed by the exam itself, and the route a candidate trains under sets the Phase II threshold at 36 or 48 months.

Planning starts with knowing which route the training follows.

ACVP describes two routes beyond the Standard Route's 36-month path to Phase II.

The Alternate Route is the longer one: 48 months of veterinary pathology training against the Standard Route's 36, for the same Phase II eligibility.

Dual certification is the route for a Diplomate certified in one discipline who seeks certification in the other: a minimum of 12 full-time months, at the equivalent of 40 hours per week, under the mentorship of a Diplomate certified in the discipline sought.

The two suit different candidates — the Alternate Route changes the length of the run to the first certification, while dual certification is the second discipline's own requirement, built on mentorship in exactly that discipline.

The certifying process runs in two phases, and the numbers are specific.

Phase I is a 2-hour examination of 100 multiple-choice questions, which may include image-based identification questions; the 12-month training gate stands in front of it.

Phase II is a one-day, 7.5-hour examination with two breaks totaling 45 minutes, composed of 300 multiple-choice questions administered in 3 sections of 100 questions each, taken in either veterinary anatomic pathology or veterinary clinical pathology.

After certification, the credential carries a maintenance obligation: all ACVP-boarded Diplomates certified in 2016 or later must meet minimum Maintenance of Certification (MOC) standards over a 10-year period.

Read together, the commitment is training counted in months, a two-examination sequence, and maintenance that continues past the exam.

The sources on file speak to the employment side only at the edges.

ACVP's candidate handbook names academia, diagnostics and industry as the employment sectors of the Diplomates who write and assemble its examinations — the college selects those writers based on experience, expertise, areas of interest, and employment sector.

AVMA's table counts 3,347 active Diplomates as of December 31, 2025, listed as 2,642 under anatomic pathology and 705 under clinical pathology.

For reading a veterinary pathology job listing, the point is that the credential is discipline-specific: Phase II is taken in anatomic or clinical pathology, so a listing that asks for certification in one discipline is asking for that discipline's credential.
