As of September 16, 2026, Colorado is the only US state with an enacted veterinary professional associate (VPA) framework, and no one has yet registered to practice as a VPA anywhere.
The scope boundaries are already fixed in statute: a credentialed veterinary technician may not diagnose, prognose, prescribe, or perform surgery; a Colorado VPA may perform only what a supervising veterinarian delegates within their advanced education and experience; a licensed DVM holds all four reserved acts outright.
This page compares the three in statutory text.
The three scopes, in Colorado's own comparison table
Colorado's official voter guide published the clearest side-by-side any government body has produced: Table 1 of the 2023–2024 Colorado Legislative Blue Book, which set the regulated provider categories — veterinary technician, veterinary technician specialist, Doctor of Veterinary Medicine, and the proposed veterinary professional associate — against each other on degree requirements and scope of practice.
Its wording is reproduced verbatim below, cell for cell, transposed so each provider category reads as a row.
| Provider category | Degree requirements | Scope of practice |
|---|---|---|
| Veterinary Technician (current law) | Either an associate's or bachelor's degree in veterinary technology. | Provides support to licensed veterinarians, including performing dental procedures, advanced nursing care, animal health education, and treating minor medical conditions. |
| Veterinary Technician Specialist (current law) | Either an associate's or bachelor's degree in veterinary technology, and three to five years of clinical experience and training. | Performs the same tasks as a veterinary technician, as well as specialized support including emergency medicine and surgical assistance. |
| Doctor of Veterinary Medicine (current law) | Advanced doctorate degree and clinical experience. | Performs all levels of care including diagnosis, prognosis, prescribing medications, and conducting surgery. Responsible for the supervision of all veterinary care. |
| Veterinary Professional Associate (under Prop 129) | Master's degree in veterinary clinical care. Additional qualifications and training may be determined by the state board. | May perform tasks that are within the individual's advanced education and training. Full scope of practice may be determined by the state board. |
Two caveats keep this table honest.
First, it is Colorado's framing, published for the November 5, 2024 ballot — no other state has enacted any VPA category, and as of the September 16, 2026 verification of this page Colorado is still the only jurisdiction with an enacted framework.
Second, the table predates HB25-1285, signed May 30, 2025 and effective January 1, 2026, which supplied the operative supervision mechanics the ballot language left open — so read the degree and scope entries as the state's official comparison, and read the supervision rules from the statutes below, not from this table.
The technician's boundary: four reserved acts, fixed in every state
The credentialed technician's scope line is a statutory negative list, and it is the same in every state: a technician may not diagnose, prognose, prescribe, or perform surgery.
Those four acts are reserved to the licensed veterinarian in every state practice act, they cannot be delegated to any technician at any credential level — including a Veterinary Technician Specialist — and no amount of floor experience moves them.
Everything below that line is state-dependent: which supervision level attaches to anesthesia induction, suturing an existing incision, dental extractions, euthanasia, radiographs, and whether a credential is required to work at all.
That task-by-task variation is its own body of law — the staff-side walkthrough is in what a vet tech can't do, and the supervision vocabulary states apply to those tasks is in the supervision-levels guide.
The structural point matters for the rest of this comparison.
The technician's boundary is written down: whatever a state permits below the four reserved acts, the line itself is fixed text, and it does not change from patient to patient or from supervisor to supervisor.
The VPA's boundary: defined by delegation, not a task list
Colorado's statutes define the VPA's scope by two ideas no technician scope language uses: delegated authority and a master's-level education.
The definition, C.R.S. 12-315-104(21.7): a veterinary professional associate "MEANS AN INDIVIDUAL WHO HOLDS A MASTER'S DEGREE IN VETERINARY CLINICAL CARE, OR THE EQUIVALENT," with qualifications the board may add.
Registration is mandatory, not optional: "COMMENCING JANUARY 1, 2026, AN INDIVIDUAL WHO PRACTICES AS A VETERINARY PROFESSIONAL ASSOCIATE IN THIS STATE MUST BE REGISTERED BY THE BOARD" (C.R.S. 12-315-203.7(3)).
On and after that date only a registered individual may use the titles "Veterinary Professional Associate" or "Registered Veterinary Professional Associate" or the initials VPA or RVPA, and practicing as a VPA without active registration is a class 2 misdemeanor (C.R.S. 12-315-210).
The practice authorization is deliberately relational rather than enumerative.
C.R.S. 12-315-105(1)(r) carves a VPA out of the practice-of-medicine prohibition only for veterinary medicine that is "(I) WITHIN THE VETERINARY PROFESSIONAL ASSOCIATE'S ADVANCED EDUCATION AND EXPERIENCE; AND (II) PERFORMED WHILE UNDER THE SUPERVISION OF A LICENSED VETERINARIAN WHO IS RESPONSIBLE FOR THE VETERINARY PROFESSIONAL ASSOCIATE'S PERFORMANCE."
The delegation clause then narrows that again, one supervisor and one VPA at a time: a VPA "SHALL PERFORM ONLY THOSE DUTIES OR ACTIONS DELEGATED BY THE LICENSED, SUPERVISING VETERINARIAN FOR WHICH THE VETERINARY PROFESSIONAL ASSOCIATE HAS THE NECESSARY TRAINING AND EXPERIENCE, AS DETERMINED BY THE SUPERVISING VETERINARIAN" (C.R.S. 12-315-209.7, effective January 1, 2026).
No statute enumerates a single VPA task.
The scope is whatever a specific supervising veterinarian has determined a specific registered VPA is trained and experienced to do — which is a different kind of boundary from the technician's, and the subject of the section after next.
Nothing on this page is evergreen
The guardrails HB25-1285 added around VPA practice
House Bill 25-1285 — signed May 30, 2025, effective January 1, 2026 — supplies the supervision mechanics the ballot initiative left open, and each provision bounds the scope from the outside:
- Supervision defaults to immediate or direct, by a licensed veterinarian responsible for the VPA's performance (C.R.S. 12-315-105.5(5)(a)(III)-(IV))
- Indirect supervision is earned, never default — it requires clinical benchmarks including a specified number of supervised hours the board has not yet set (12-315-105.5(9))
- Telesupervision of a VPA practicing veterinary medicine is not permitted
- One supervising veterinarian may supervise no more than three VPAs practicing at any one time (12-315-105.5(3.5)(d))
- Supervising vet and VPA must be at the same veterinary premises while the VPA practices, unless the indirect-supervision benchmarks are met (12-315-105.5(3.5)(c))
- A written supervisory agreement is required, kept on file at both parties' places of business, covering training verification, the three-VPA cap, species, and dates (12-315-203.7(6))
- The VPA must identify themself to the client both visually and verbally as a veterinary professional associate, and employers must disclose that a VPA is providing the care (HB25-1285)
- An employer may not require a veterinarian to supervise a VPA as a condition of continued employment (12-315-121(3)(b))
Read together, the guardrails answer the question the scope language leaves open.
The boundary is not only what a VPA knows — it is where the work happens, under whose eyes, and on whose written agreement.
A role whose scope is delegated case by case, whose off-premises practice is gated on hour thresholds that were still unwritten at verification, and whose supervision cannot happen remotely has a practical scope that was, as of September 16, 2026, narrower than its statutory envelope.
What stays with the DVM under the same statutes
The DVM row of the comparison table is unchanged by all of this: the licensed veterinarian performs all levels of care — diagnosis, prognosis, prescribing, surgery — and is responsible for supervising all veterinary care.
What the VPA statutes add is a precise restatement of where the veterinarian's exclusivity survives delegation.
The veterinarian-client-patient relationship must be established by the licensed veterinarian before any task — including VPA tasks — is delegated, which means a VPA cannot originate a VCPR (C.R.S. 12-315-105.5(2)).
Prescribing shows the same shape: Colorado's definition of "prescriber" for electronic controlled-substance prescribing includes "A VETERINARIAN LICENSED PURSUANT TO ARTICLE 315" and does not list the VPA (C.R.S. 12-30-109(4)) — the clearest statutory evidence in the record that VPAs hold no independent prescribing authority.
And the delegation clause cuts against the supervisor, not the VPA: delegating duties beyond a VPA's training violates C.R.S. 12-315-112(1)(ee), and the supervising veterinarian may be liable for the VPA's negligence.
The four reserved acts themselves were not re-allocated by Proposition 129 or HB25-1285.
What the framework changes is who may perform delegated work beneath them — and AVMA's opposition, below, is precisely the argument that a delegation-defined scope will drift into reserved territory.
The acts themselves are covered in what only a veterinarian can do, and the VCPR's separate state and federal layers in the VCPR and telemedicine guide.
Why the VPA's scope is harder to pin down than either of the others
Set the three boundary styles side by side and the structural difference is the finding.
The technician's line is a fixed statutory negative list — four named prohibitions, identical in every state.
The DVM's line is a fixed grant — all four reserved acts plus everything not reserved to the license.
The VPA's line is neither: it is a formula (advanced education and experience), applied by an individual supervisor (the delegation determination), to a registrant class that had no members at verification, under rulemaking that was still incomplete.
This is not a neutral observation — it is the contested ground.
The Blue Book's official "Argument Against" states it directly: "The measure's education and training requirements are vague and do not differentiate veterinary professional associates from existing veterinary care professionals." The table's own VPA row — "Full scope of practice may be determined by the state board" — is not a list anyone can read in advance, and that openness is what opponents mean by vague.
The defense is that delegation-defined scope is how veterinary teams already work: a supervising veterinarian making a per-person, per-task competency determination is the delegation duty every practice act already imposes, now applied to a master's-level registrant.
Both readings describe the same statutory text.
In practice, what a given VPA may do on a given day resolves to the written supervisory agreement — not to any published task list.
What the disagreement is really about: who draws the scope line
Strip the organized positions down to scope and the dispute is a single question: is the line between the veterinarian's reserved acts and everyone else drawn by statute or by delegation?
AVMA's opposition holds that a delegation-defined scope will drift into reserved territory — diagnose, prognose, prescribe, operate — which is why it opposes mid-level authorization in principle; CVMA and NAVTA object from the same direction, NAVTA proposing an expanded credentialed-technician pathway instead.
The other side answers that delegation is already how veterinary teams work lawfully, and a master's-level registrant merely formalizes the competency determination every practice act already requires of supervising veterinarians.
Both cases in each organization's own words — AVMA's 2023 pet-owner survey, CVMA's competence-assessment objection, NAVTA's March 12, 2026 statement, AAVSB's split position on the credentialing exam, and the workforce numbers each side campaigns on — are carried in full, with citations, on the case for and against the mid-level practitioner.
This page stays with what the statutes fix; the politics are that page's territory.
Where else this exists
As of September 16, 2026: Colorado is the only US jurisdiction with an enacted VPA framework, and no one has yet been registered to practice as a VPA anywhere — the national credentialing exam was still in development.
Outside Colorado, the degree itself confers nothing: CSU's own program page tells applicants that "the scope of practice of the VPA will be defined by each state's veterinary practice act."
The one other genuine legislative front has been Florida, whose 2026 bill cleared every Senate committee before dying on the calendar — the closest any state has come, and not law.
The full dated tracker, with both sessions' bill history and the committee tallies, is carried on the case for and against the mid-level practitioner.
Nothing on either page is evergreen: "only Colorado" is a statement about September 16, 2026, not about next year.
What this means if you're plotting a career around it
Nobody holds this role yet.
The national credentialing exam was still in development at verification, DORA's own licensing guide (February 2025) states registrations "may not be obtained until sometime in late 2026," and the only degree pathway has not graduated a cohort.
Treat the VPA as a statutorily defined, presently unstaffed role: real law, no incumbents.
One degree pathway exists anywhere.
Colorado State University's Master of Science in Veterinary Clinical Care runs five semesters — three online and synchronous, a fourth with 416 hours of in-person campus training, and a fifth as a 540-hour clinical internship with an approved community shelter or practice.
Applications opened February 3, 2026, with CSU expecting to admit 20 to 30 students.
Admission requires a bachelor's degree, a 3.0 GPA, prerequisite coursework, and 150 hours of verifiable veterinary experience — a credentialed-technician background is not required.
The program is small-animal and shelter focused, and CSU publishes no program tuition; the only figure in the record is AVMA's calculation against CSU's 2024-25 graduate rates — $34,430 in-state and $77,151 out-of-state for the earlier 65-credit-hour draft of the curriculum — an estimate keyed to a credit count that may not match the launched program.
The technician bridge is narrower than headlines suggest.
HB25-1285 lets the board count a registered veterinary technician specialist's training toward the VPA education requirement — but must still require that specialist to pass the same national credentialing examination as everyone else (C.R.S. 12-315-201(4)).
No automatic conversion exists.
For credentialed technicians, the advancement pathway that exists today, in every state, is the specialist route — how to become a VTS — alongside NAVTA's proposed progressive technician education.
What the role would mean for technicians day to day — pay, the specialist bridge, NAVTA's plan in full — is its own page: what the mid-level role would mean for technicians.
For veterinarians, the framework changes the supervision and liability surface, not the license: the four acts on your license are where they were, and open veterinarian roles look, for now, exactly as they did before Proposition 129 passed.
This page compares statutory text for career-planning purposes and is not legal or veterinary advice. Scope, supervision, and registration rules are set by each state's veterinary board and were changing as of the September 16, 2026 verification — confirm current requirements with the Colorado State Board of Veterinary Medicine or your own state board before acting on them.
