What Can a Vet Tech Do in Missouri?

Missouri's answer comes from two rules read together.

The 4.060 supervision table names four of our eleven benchmark tasks by supervision tier — anesthesia induction, anesthesia monitoring, euthanasia and rabies vaccination — and 3.050's prose adds a fifth, IV catheter placement, plus a general catch-all for other auxiliary tasks a veterinarian assigns under direct or indirect supervision.

That leaves six benchmark tasks the text does not name at all: intubation, dental extraction, suturing, radiographs, cystocentesis and dispensing.

For a technician or a practice manager, that means checking two rules before treating any task as covered, not one.

Immediate supervision means the veterinarian is in the immediate area and within audible and visual range of the patient and the person treating it.

Direct supervision means the veterinarian is on the premises and quickly and easily available.

Indirect supervision means the veterinarian need not be on the premises but has given instructions, the patient is not in a surgical plane of anesthesia, and the veterinarian is available for consultation at least daily.

The table's fourth designation, "Not Legal," is not a supervision tier at all — it means that personnel category may not perform the task regardless of who is supervising.

The prose rule bars a registered veterinary technician from surgery, diagnosis and prognosis, and prescribing, plus any other activity requiring a licensed veterinarian's knowledge, skill and training.

The supervision table confirms the same line: the RVT row reads "Not Legal" on the Surgery, Diagnosis, Prescribing-Controlled and Prescribing-Not Controlled columns, with no supervision level that unlocks any of them.

Those four hold at every tier, for both a registered technician and an unregistered assistant.

A registered technician may induce anesthesia and monitor it under direct supervision, the veterinarian on the premises and quickly available.

A footnote narrows induction to administering a pre-calculated dose rather than independently selecting one — the judgment call stays with the veterinarian even when the injection does not.

An unregistered assistant may not induce anesthesia at all, and may only help monitor it under the tighter immediate-supervision tier, the veterinarian in sight and hearing.

The supervision table's only dental column is "Routine Dental Prophylaxis," which reads direct supervision for the RVT row and immediate supervision for the unregistered assistant row — that is cleaning and polishing, not pulling a tooth.

Neither the table nor the 3.050 prose list names dental extraction by name at any supervision level.

This page leaves that cell "Not stated in the sources read" rather than reading the prophylaxis column, or the Surgery column's "Not Legal" mark, as an answer to a question the text does not address.

The supervision table marks the RVT row "Not Legal" on Surgery, and the prose rule reserves surgery to the veterinarian.

Neither source names suturing or skin closure specifically, at any supervision level, for either a registered technician or an unregistered assistant.

This page does not go further than that: it neither lists suturing as a permitted task nor states that it is barred by name.

A technician asked to close an incision in Missouri should raise the question with the Missouri Veterinary Medical Board rather than rely on a reading of the surgery bar.

Euthanasia is a named column: direct supervision for the RVT row, immediate supervision for the unregistered assistant row, so both roles may perform it at their respective tier.

Rabies vaccination runs the opposite way.

The "Administer Rabies/Brucellosis" column reads "Not Legal" for both the RVT row and the unregistered assistant row — a flat bar rather than a supervision requirement, so no degree of oversight makes it permitted for either role under this table.

An unregistered assistant is defined only by what they are not: any individual who is not a registered veterinary technician or licensed veterinarian and is employed by a licensed veterinarian.

The supervising veterinarian must determine competency and examine the patient before delegating to either an RVT or an assistant, the same duty either way.

On most tasks where both roles may work, the table moves the assistant to a tighter, more vet-proximate tier — anesthesia monitoring, euthanasia, off-facility patient care, vaccine/medication administration and routine dental prophylaxis all step down from the RVT's direct or indirect tier to the assistant's immediate tier.

One column breaks that pattern: patient care and treatment given at the facility reads indirect supervision for both the RVT row and the unregistered assistant row — the same tier for both.

The board's rule of professional conduct closes with the title rule: only an individual registered by the board may use the designation "RVT" with their name.

Missouri's own statute calls the credential a registration rather than a license, defining a registered veterinary technician by training and supervised function (RSMo §340.200(21)).

For a job seeker, a Missouri posting for a registered veterinary technician means the credentialed role, not any employee doing similar work.

The version of the supervision table this page summarizes was filed June 17, 2025 and took effect Feb. 28, 2026, superseding an amendment filed Sept. 18, 2024 that took effect April 30, 2025 — itself the first change to a table that had otherwise stood unchanged since April 30, 2008.

What substantively moved between the 2025 and 2026 versions was not established from the sources read for this page.

Treat the table summarized here as the version current as of September 2026, and confirm with the board that nothing has moved again before relying on a specific task cell.
