Colorado assigns each veterinary-technician task a minimum supervision tier by rule, but anesthesia induction and intubation are not named anywhere — though an unlisted task still falls under the rule's catch-all, delegable at the veterinarian's discretion.
A registered technician may perform single-root dental extractions, suture an existing incision, take diagnostic images, and collect urine samples under direct or indirect supervision, at minimum, and rabies-vaccine delegation is addressed by training rather than by credential.
For anyone who is not a registered technician, Colorado's general clause defaults to direct or immediate supervision, though a narrow rule-based exception opens indirect supervision for shelter-animal work.

Three, statutorily defined: direct supervision (the veterinarian readily available on the premises and able to supervise the task), immediate supervision (the veterinarian physically in the immediate area, within audible or visual range), and indirect supervision (the veterinarian off the premises but having given written or verbal instructions and staying reachable).
4 CCR 727-1, Rule 1.7(B)(4) names three categories that may not be delegated to a technician, specialist, or other qualified personnel: diagnosing, prognosing, prescribing, and performing surgery; tasks legally restricted to licensed veterinarians by state or federal law or regulation; and any task that, in the veterinarian's own judgment, requires their direct involvement to ensure patient safety.

Colorado's board was required to adopt rules naming which tasks a veterinarian may delegate to a veterinary technician or veterinary technician specialist, and the minimum supervision tier for each.
The result is three tiered lists — immediate, direct at minimum, and indirect at minimum — rather than a single delegation standard left entirely to a veterinarian's judgment.
For a technician weighing a Colorado job, the question is answerable by finding the task in the statute or the board's rule and reading the tier; for a practice manager writing a delegation policy, the statute and rule can be quoted directly.
“A licensed veterinarian may delegate the following tasks to a veterinary technician or veterinary technician specialist who is under at least direct supervision by the licensed veterinarian”
Direct supervision means the veterinarian is readily available on the premises where the patient is being treated and able to supervise the delegated task.
Immediate supervision is stricter: the veterinarian must be physically in the immediate area, within audible or visual range of the patient and the person performing the task.
Indirect supervision is the loosest tier — the veterinarian need not be on the premises at all, so long as written or verbal instructions have been given and the veterinarian stays readily available for communication.
Colorado's task lists set each tier as a minimum, so a veterinarian may always choose closer supervision than the rule requires, but never less.
“Direct supervision means the supervising licensed veterinarian is readily available on the premises where the patient is being treated and is able to supervise the tasks that have been delegated to an individual.”
The statute itself is written as a list of what may be delegated rather than a list of what is reserved, but the board's implementing rule states the restrictions directly. 4 CCR 727-1, Rule 1.7(B)(4) bars delegating three categories to a technician, specialist, or other qualified personnel: diagnosing, prognosing, prescribing, and performing surgery; any task legally restricted to licensed veterinarians by state or federal law or regulation; and any task that, in the veterinarian's own judgment, requires their direct involvement to ensure patient safety.
The rule separately excludes the use of surgical lasers from the indirect-tier therapeutic-laser grant.
“The following tasks cannot be delegated to VTS, RVT, or other qualified personnel: a. Diagnosing, prognosing, prescribing, and performing surgery. b. Tasks legally restricted to licensed veterinarians by state or federal laws or regulations. c. Any task that, in the veterinarian's judgment, requires their direct involvement to ensure patient safety.”
Colorado's task-tier lists do not name anesthesia induction, endotracheal intubation, or anesthesia maintenance anywhere — not in the statute's task lists, and not in 4 CCR 727-1's full task lists, which restate them, read in full.
That is not the same as the rule going unaddressed for tasks it doesn't enumerate: 4 CCR 727-1, Rule 1.7(C)(3) states that "tasks that are not listed below may be delegated at an appropriate level of supervision as determined by the licensed veterinarian," subject to the Rule 1.7(B)(4) restrictions.
Separately, the indirect-supervision list grants general vital-sign monitoring — an electrocardiogram, blood pressure, and carbon dioxide and blood oxygen saturation — which is not itself an anesthesia-specific permission.
“Various tasks that a veterinarian may choose to delegate under immediate, direct, and indirect supervision are summarized below and a table is provided. Tasks that are not listed below may be delegated at an appropriate level of supervision as determined by the licensed veterinarian.”
Under a minimum of direct supervision, a technician may perform dental procedures including, at a minimum, calculus, soft-deposit, plaque and stain removal, smoothing, filing and polishing teeth, single-root extractions that do not require sectioning the tooth or bone, and suturing a gingival incision — a non-exhaustive list, not a ceiling.
The actual limit on heavier extraction work is 4 CCR 727-1, Rule 1.7(B)(4)(a)'s bar on delegating "performing surgery," which reserves a sectioned-tooth or bone-resectioning extraction to the veterinarian.
“Single root extractions that do not require sectioning of the tooth or sectioning of the bone”
Colorado's direct-supervision-minimum list names suturing, stapling, or gluing an existing surgical skin incision as a delegable technician task, alongside suturing a gingival incision.
That is narrower than a general suturing permission: it covers closing an incision the veterinarian has already made, not performing surgery or creating a new one.
Colorado does separately address surgical assistance: "assisting in surgical procedures" is itself a named task, delegable under a minimum of immediate supervision.
Performing surgery itself is reserved to the veterinarian, under 4 CCR 727-1, Rule 1.7(B)(4)(a)'s restriction on delegating "diagnosing, prognosing, prescribing, and performing surgery."
“Suturing, stapling, or gluing an existing surgical skin incision”
Colorado's implementing rule does not grant a technician a standalone permission to euthanize.
Euthanasia is item six within a longer, indirect-supervision-minimum "Emergency patient care" list: the administration of a drug, a controlled substance, or parenteral fluids to manage and control pain, prevent further injury, prevent or control shock, or prevent the suffering of an animal, "up to and including euthanasia." Rabies vaccination has its own dedicated provision, separate from the general biological-immunological-agents grant: a veterinarian may delegate administering the vaccine to a person under direct supervision who has rabies-vaccine training, or under indirect supervision if that person is working on behalf of an animal shelter and has the same training.
The signing veterinarian must identify the administering person on the certificate.
“the administration of a drug, a controlled substance, or parenteral fluids to manage and control pain, prevent further injury, prevent or control shock, or prevent the suffering of an animal, up to and including euthanasia”
Colorado writes no task-specific list for an assistant or other unlicensed staff member.
Instead, a general clause lets a veterinarian delegate a task to an individual who is not a veterinary technician or specialist, if the veterinarian determines the task is within that individual's training and experience and the individual works under direct or immediate supervision.
The one express carve-out is "treatment of minor medical conditions," which the rule prohibits delegating to a non-technician.
That default is not the whole picture: Rule 1.7(C)(6) opens indirect supervision for shelter-property animals if the statutory shelter conditions are met, Rule 1.7(C)(7) sets a separate livestock route conditioned on a VCPR and written or verbal instructions, and Rule 1.7(C)(8)(b) opens indirect supervision for shelter rabies-vaccine work.
A technician may work under indirect supervision on several tasks by default; an assistant needs one of these narrower routes to do the same outside those settings.
“a licensed veterinarian may delegate a task to an individual who is not a veterinary technician or veterinary technician specialist if the veterinarian determines that the task is within the individual's training and experience and the individual is under the veterinarian's direct or immediate supervision”
Colorado protects the title separately from the task lists: only a person registered with the Colorado State Board of Veterinary Medicine may use the title "veterinary technician," "registered veterinary technician," or the initials "VT" or "RVT." An assistant performing delegated work under the general clause is not entitled to any of those titles, regardless of experience.
For a job seeker, a Colorado posting for a "veterinary technician" or "RVT" means the registered role, tied to Colorado's registration requirement.
“On and after January 1, 2024, only an individual who is registered pursuant to section 12-315-203 may use the title "veterinary technician" or "registered veterinary technician" or the initials "VT" or "RVT".”
The delegation and task-tier framework in § 12-315-105.5 is effective January 1, 2026, added by 2022 legislation and amended in 2024.
The 2025 legislature amended the section again through HB25-1285, effective January 1, 2026: that bill built out a delegation framework for a new role, the veterinary professional associate, created by a 2024 ballot measure, and it left the technician and other-qualified-personnel task provisions this page describes unchanged.
The board's implementing rule, 4 CCR 727-1, carries a currently effective version dated May 30, 2026, published May 10, 2026.
Among the states in this series, Colorado's framework is one of the most recently overhauled, so a technician, assistant, or practice manager relying on this page should also check the board's rule directly for any amendment made after that date.
This page describes Colorado’s own text — Colo. Rev. Stat. § 12-315-105.5 (delegation to and supervision of veterinary technicians), implemented by 4 CCR 727-1, the Colorado State Board of Veterinary Medicine's veterinarian and veterinary technician rules. as read for this series, current as of September 2026. It does not cover how to earn the credential, what a particular employer’s protocols require, or how the board would decide a specific complaint.
A practice may always be stricter than the rule. Where the text names a task, this page says who may do it and under what supervision; where it does not, this page says so and stops. Confirm the current rule with the board before you perform, delegate or refuse a task on the strength of it.
Colorado's task-tier statute and its implementing rule do not name anesthesia induction, endotracheal intubation, or anesthesia maintenance anywhere — absent from 4 CCR 727-1's full task lists, which restate the statute's.
That silence is not the last word: the rule's catch-all lets a veterinarian delegate any unlisted task "at an appropriate level of supervision as determined by the licensed veterinarian" (4 CCR 727-1, Rule 1.7(C)(3)), subject to the diagnosing/prescribing/surgery restrictions.
The rule does separately grant general vital-sign monitoring (an electrocardiogram, blood pressure, and carbon dioxide and blood oxygen saturation) at a minimum of indirect supervision, but that is not an anesthesia-specific permission.
Confirm the current rule with the Colorado State Board of Veterinary Medicine before relying on this.
Yes, within the rule's non-exhaustive dental list: a single-root extraction that does not require sectioning the tooth or bone, under a minimum of direct supervision — the veterinarian readily available on the premises (§ 12-315-105.5(4)(b)(I)(C)).
The list reads "including, at a minimum," so it names a floor, not a ceiling; the actual limit on heavier extraction work is 4 CCR 727-1, Rule 1.7(B)(4)(a)'s bar on delegating "performing surgery." Check the current rule with the Colorado State Board of Veterinary Medicine.
Yes, within a narrow grant: suturing, stapling, or gluing an existing surgical skin incision, and suturing a gingival incision, are both delegable under a minimum of direct supervision (§ 12-315-105.5(4)(b)(I)(D), (III)).
That covers closing an incision the veterinarian already made — it is not a general surgery permission.
Confirm the current rule with the Colorado State Board of Veterinary Medicine.
Colorado writes no task-specific list for an assistant.
A veterinarian may delegate a task to a non-technician under direct or immediate supervision by default, if it is within that person's training and experience (§ 12-315-105.5(7)).
That default is not absolute: the rule opens indirect supervision for shelter-property animals if the statutory shelter conditions are met (4 CCR 727-1, Rule 1.7(C)(6)), a separate livestock route conditioned on a VCPR and written or verbal instructions (Rule 1.7(C)(7)), and shelter rabies-vaccine work.
The one express exception from the general clause is "treatment of minor medical conditions," reserved to a technician or specialist.
Confirm current requirements with the Colorado State Board of Veterinary Medicine.
There is no standalone "may euthanize" task in Colorado's rule.
Euthanasia is item six within a longer "Emergency patient care" list: at a minimum of indirect supervision, a technician may administer a drug, controlled substance, or parenteral fluids to manage pain, prevent injury or shock, or prevent suffering, "up to and including euthanasia" (4 CCR 727-1, Rule 1.7(C)(3)(c)(21)).
That emergency-care list is how a technician reaches euthanasia in Colorado.
