What is the NAVLE? A guide for internationally trained veterinarians
The NAVLE (North American Veterinary Licensing Examination) is the licensing examination administered by the International Council for Veterinary Assessment (ICVA), and it is required to practise veterinary medicine in both the United States and Canada. It does not matter which university you attended. Every veterinarian, domestic or international, has to pass it.
What the exam actually looks like
The NAVLE is 360 clinically relevant multiple-choice questions, delivered in English by computer at Prometric testing centres. It covers general clinical practice: small animal, large animal, public health and pharmacology among other areas.
It is offered in three windows a year, which typically fall in autumn (roughly mid-October to mid-November), spring (March) and summer (July into August). Those windows matter more than most candidates expect. Miss one and you are usually waiting months for the next, so the window you target should be the fixed point you plan everything else around.
Who can sit it directly
This is where your university matters.
If you graduated from a school accredited by the AVMA Council on Education, you qualify to sit the NAVLE directly. Every veterinary school in Canada is accredited. UNAM's FMVZ in Mexico held AVMA accreditation from 2011 to 2025, so graduates from those cohorts have the same direct route.
If your school is not on that list, eligibility runs through an equivalency programme, either the ECFVG or the PAVE. Worth knowing precisely: the ICVA's requirement is that you are enrolled in one of those programmes, not that you have finished it. Candidates routinely misread this as needing full certification before they can test, and lose a testing window to the misunderstanding. Confirm your own status against the ICVA's current eligibility rules rather than against advice from a forum.
What the pass rates actually look like
Be prepared for a demanding examination in technical English, and know that it has been getting harder to pass.
The ICVA publishes an ultimate performance passing rate for senior students from AVMA-accredited schools. That figure has fallen steadily: 95 percent in 2019-20, 92 percent in 2020-21, 90 percent in 2021-22, and 86 percent in 2022-23, according to ICVA annual reporting. Candidate volume rose sharply over the same period, from 7,019 candidates in the 2021-22 cycle to 8,230 in 2022-23, an increase of about 17 percent.
Two honest caveats on those numbers. They describe senior students at accredited schools, not international candidates, and the ICVA does not publish a separate headline pass rate for internationally trained examinees. So treat the trend as a signal about the examination's difficulty, not as a prediction of your own odds.
What that trend does tell you is that casual preparation is a bad bet. The difference between passing and not passing is usually structured preparation: a serious study plan, question banks, timed practice examinations, and guidance from people who have already sat it.
If you do not pass the first time
Failing the NAVLE is common enough that it should not end your plans, and the attempt rules recently became considerably more forgiving.
Since the March 2026 testing window, the ICVA grants every candidate five new opportunities to sit the NAVLE regardless of their prior testing history, and attempts made before December 2025 do not count against that allowance. In practice this means candidates who had previously exhausted their attempts under the old rules were given a clean slate.
Plan for the possibility anyway. Build your timeline around the assumption that you might need a second window, because a candidate who has budgeted for that is in a far better negotiating position than one whose visa timing depended on passing first time.
Where it fits in the whole path
The NAVLE is the longest single step in the process, which is exactly why it should be the first one you start rather than the one you leave until the visa is sorted.
After it come state licensure, a job offer, and the TN visa if you are a Canadian or Mexican citizen. Taken together, the path from a signed offer to your first shift typically runs 2-3 months, and the biggest variable within that is when your NAVLE window falls and whether you need ECFVG or PAVE first.
One detail worth knowing before you plan around a specific state: some states, New York among them, issue a limited permit that lets a qualified veterinarian work under supervision while full licensure is completed. That does not replace the NAVLE, but it can change when you start earning.
At VetBridge USA we support candidates through that preparation with tutors and mentor veterinarians who have been through the process themselves, and we coordinate the rest of it: licensure, visa and placement with a US clinic. The pathway itself is well established and has been for years.
