Veterinarian Licensure Requirements in Colorado

Colorado's rule requires each applicant to have successfully completed the North American Veterinary Licensing Examination administered by the International Council for Veterinary Assessment after November of 2000 — a date cutoff that places the current rule in the post-2000 exam era.

Colorado's own rule text does not restate a passing score, so the operative standard is the one the exam administrator sets; confirm the current score requirement with the Board before you schedule.

The NAVLE is also only one input: every applicant must separately demonstrate current clinical competency, and a NAVLE passed within one year of the application date is one of the ways to satisfy that requirement.

Colorado does not administer a pass/fail examination on state veterinary law.

The state-specific layer instead arrives as a continuing education obligation: every renewal period must include two hours of jurisprudence on the Colorado Veterinary Practice Act.

For a new applicant that changes the sequencing — there is no jurisprudence test to schedule before licensure, but the Practice Act requirement is waiting inside your first renewal cycle, so it is worth reading the Act before your first renewal rather than after it.

An applicant graduating from an AVMA-accredited school submits an official transcript or a dean's letter confirming the DVM degree.

A graduate of a non-approved school instead submits an ECFVG or PAVE certificate in lieu of transcripts — both programs are named in the rule, and they are run by different bodies: ECFVG is the AVMA's program, PAVE the AAVSB's.

Every applicant must also demonstrate current clinical competency through at least one pathway: three of the last five years in active licensed clinical practice (postgraduate training, residencies, internships and research are evaluated case by case), a DVM or an ECFVG/PAVE certificate earned within the last twelve months, three of the last five years teaching in an AVMA-accredited program or serving as a military veterinarian, a NAVLE passed within the last year, or a Board pre-approved competency evaluation by an AVMA-accredited institution completed within the last year.

A relocating veterinarian will usually travel the three-of-five-years practice route; a long-dormant license is the scenario that needs planning.

An endorsement applicant certifies they hold no revoked, suspended, restricted or conditional license — and are not facing pending disciplinary action — in another state or territory of the United States or through the federal government, and verifies through the licensing state that they meet the same education and NAVLE requirements as exam applicants.

The current-clinical-competency pathways apply to endorsement applicants too, so endorsement is not a paperwork-only shortcut: a relocating veterinarian who has been continuously practicing clears it through the practice-years route, while one returning from a long break may need the NAVLE-within-a-year or Board-approved evaluation route.

Colorado's board is also mid-rulemaking (an August 24, 2026 stakeholder meeting) to implement HB 26-1198, which speeds the process by which a veterinarian is licensed by endorsement — check the board's site for where those rules stand before you file.

Licenses renew biennially, and each active licensee completes 32 hours of continuing education per two-year renewal period, which must include 2 hours of jurisprudence on the Colorado Veterinary Practice Act, at least 1 hour of substance-use-prevention training (the statutorily specified topics cover veterinary opioid prescribing, recognition of human substance use disorder, use of the prescription drug-monitoring program, and referral to treatment), and 2 hours of supervision training covering delegation to veterinary technicians, technician specialists, veterinary professional associates and other staff.

RACE-approved courses are automatically accepted, and up to 16 hours per period may come from non-biomedical topics such as leadership, personnel management, client relations, communication, and practice and personal wellness.

The first cycle is prorated: no continuing education is required if the renewal date falls during the year of original Colorado licensure, and 16 hours are required if it falls the following year.

The only temporary license the sources show is for military spouses: a person duly licensed in good standing in another state or U.S. territory, and the spouse of a service member stationed in Colorado on military orders, may obtain a temporary license on proof under penalty of perjury of that active license and of no act that would be grounds for discipline under the Practice Act.

It is valid for three years from issuance, may not be renewed, and the Board waives the application fee.

No general relief or locum tenens permit appears in the sources read, so a relief veterinarian covering short stints in Colorado needs a full license — by examination or endorsement — and should build that processing time into any relief contract.

Where the standard competency pathways don't fit, the Board may apply alternatives: practice under a probationary or otherwise restricted license for a specified period, successful completion of Board-approved courses, or any other professional standard or measure of continued competency the Board determines, including species-specific examinations.

For a relocating veterinarian whose recent work sits in one species area, a species-specific exam can be worth raising with the Board directly — and note that any proposed Board-approved evaluation must be submitted for pre-approval before it is begun.

Ask the Board which measures it will accept for your situation before relying on one.
