Washington's scope rule is a set of task tables: one tier column for the licensed veterinary technician (LVT), one for the unregistered assistant.
An LVT induces, intubates, maintains anesthesia, sutures and performs euthanasia under direct supervision; single-root extractions sit at immediate; cystocentesis, radiographs and IV catheters at indirect.
An assistant may maintain anesthesia and monitor a patient under immediate supervision, take radiographs and place IV catheters under direct — and is prohibited from inducing, intubating, closing wounds or performing euthanasia.
Rabies biologics are direct-tier work for both, certificates required.

At a glance
A veterinary technician license issued under RCW 18.92 and WAC 246-935 by the Washington Veterinary Board of Governors through the Department of Health; the holder is commonly styled an LVT.
Four per task — immediate, direct, indirect, prohibited — set in separate columns for the LVT and the unregistered assistant (WAC 246-935-050); WAC 246-935-010 defines each tier, and unlisted delegated tasks default to indirect supervision (050(2)).
Surgery except as the tables outline; diagnosis and prognosis; prescribing drugs, medication or appliances; and initiation of treatment without prior veterinary instruction except under emergency animal care (WAC 246-935-050(1)).
RCW 18.92.015(11) ties the title to licensure, and WAC 246-935-050's opening line bars anyone else from advertising as a trained or licensed veterinary technician; the chapter's penalty clause does not name the title as a separate offense.
Both rules shown effective April 6, 2026 (current version) — WSR 26-07-008, filed March 6, 2026, a recent re-issue of the task tables.

Washington's board did not leave delegation to a general judgment clause.
WAC 246-935-050 tables specific animal health care tasks in a grid — a column each for the licensed veterinary technician and the unregistered assistant, every cell reading immediate, direct, indirect or prohibited.
Subsection (2) then supplies the default: tasks not specifically listed or otherwise restricted may be performed by either person, when the veterinarian delegates them, under indirect supervision.
The veterinarian's delegation is a condition of the default, not something the tables do themselves.
A task the tables name is governed by its stated tier, so a practice policy should quote the row rather than lean on the default for work the tables already tier.
“may be performed by a licensed veterinary technician or unregistered assistant under the indirect supervision of a veterinarian”
The chapter defines its own tiers in WAC 246-935-010: direct supervision means the supervisor is on the premises and quickly and easily available, with the patient examined as practice requires; immediate supervision means the supervisor stays in audible and visual range of the patient and the person treating it, and immediate supervision of an unregistered assistant requires consultation and instruction from the supervisor; indirect supervision means the supervisor is off the premises working from written or oral instructions — and, notably, that the animal patient is not anesthetized.
The tables nonetheless tier the LVT's monitoring of a sedated or anesthetized patient at indirect supervision; how those two provisions fit together is a question for the board rather than something this page resolves.
A supervisor, per the definitions section, is either a veterinarian or a licensed veterinary technician.
Subsection (1) opens the rule with a prohibited list naming both the LVT and the unregistered assistant: surgery except as outlined below, diagnosis and prognosis, prescribing drugs, medication or appliances, and initiation of treatment without prior instruction by a veterinarian except as outlined under emergency animal care.
The "except as outlined below" language ties surgery back to the task tables — the closure and extraction rows are that outline.
Emergency animal care is the second door: under subsection (4), in an emergency both an LVT and an assistant may render life-saving aid at indirect supervision, with pharmacologic agents and parenteral fluids only after communication with a veterinarian, and nothing in that table bars basic first aid in the absence of a veterinarian or LVT.
Complex or surgical dental extractions stay reserved to the veterinarian, which is why the extraction row reaches only single-root teeth.
“Licensed veterinary technicians and unregistered assistants are prohibited from performing the following activities: (a) Surgery except as outlined below; (b) Diagnosis and prognosis; (c) Prescribing drugs, medication or appliances; (d) Initiation of treatment without prior instruction by a veterinarian except as outlined under emergency animal care.”
Table A puts induction, intubation and maintenance of anesthesia all at direct supervision for the LVT — the supervisor on the premises and quickly and easily available.
The unregistered assistant is prohibited from inducing and intubating, but maintenance is not barred: the assistant may maintain anesthesia under immediate supervision, with the table noting that it requires supervisor consultation.
Monitoring a sedated or anesthetized patient is its own row — indirect for the LVT, immediate for the assistant.
The chapter's definitions add that immediate supervision of an assistant always carries consultation and instruction from the supervisor, so the maintenance row's note restates the general rule.
The dental extraction row sets a mechanical test — single-root extractions, canine teeth excluded, that do not require sectioning of the tooth or sectioning of the bone or an incision of the gingiva — and tiers it at immediate supervision for the LVT, the tightest tier the tables give the technician, and prohibited outright for the assistant.
Dental prophy runs the other way: indirect for the LVT, immediate for the assistant.
Floating teeth is direct-tier LVT work, prohibited for the assistant.
Anything beyond the extraction row's limits falls to the veterinarian under the subsection (1) surgery reservation.
Washington's table answers the suturing question on its face: closure, including suturing of prepared skin wound or gingival incision, is a direct-supervision task for the LVT and prohibited to the unregistered assistant.
The same table separates closure from removal — taking out sutures, drain tubes and staples is indirect work for the LVT and direct work for the assistant, as is removal of exposed foreign bodies.
Casts, splints and slings are direct-tier for the LVT, prohibited for the assistant.
The surgery reservation in subsection (1) reads "except as outlined below," and closure of a prepared wound is one of the outlines the tables draw.
Table E places euthanasia in the LVT's direct column and prohibits it outright for the unregistered assistant — the assistant may maintain an anesthetic plane and monitor the patient, but the euthanasia row is not theirs.
Vaccines run through two tables: Table F tiers vaccines other than rabies and the subsection (8) diseases at indirect for the LVT and direct for the assistant, with the veterinarian's verification signature on an appropriate certificate; Table G tiers veterinary biologics for rabies — and the diseases listed in WAC 16-42-026(1) — at direct supervision for both.
Subsection (5) sets the rabies certificate's required contents, down to the veterinarian's signature.
Table K separately bars the assistant from controlled-substance work and keeps the LVT's own packaging, preparation, administration or delivery of controlled substances at indirect supervision (see also WAC 246-935-420).
Subsection (3) lets the assistant work under a licensed veterinarian or a licensed veterinary technician.
WAC 246-935-040 then adds the cascading rule: when an LVT supervises an assistant on a specified health care task, the LVT must be under the same degree of veterinary supervision as if performing the task.
The supervising veterinarian delegates only to someone qualified, competent, educated, trained and able, examines the patient before delegating, keeps every diagnosis and treatment decision, and may limit how many assistants work under indirect supervision.
On the tables, the assistant's prohibited rows include induction and intubation, casts and closure, extractions and floating teeth, centesis, euthanasia, urinary catheter placement, arterial and central venous catheters, blood administration and controlled substances; the immediate-tier rows include maintenance of anesthesia, monitoring, dental prophy, fine needle aspirates, intra-testicular blocks and IV injections in uncatheterized veins.
Dispensing pharmaceuticals requires registration as a veterinary medication clerk under ch. 246-937 WAC.
“the licensed veterinary technician must be under the same degree of supervision by the veterinarian”
RCW 18.92.015(11) defines "veterinary technician" as a person licensed by the board, and WAC 246-935-050's opening line bars any individual other than a licensed veterinary technician from advertising or offering services in a manner calculated to lead others to believe they are a trained or licensed veterinary technician.
What the chapter does not do is separately criminalize unlicensed use of the title — the general penalty clause reaches unlicensed practice of veterinary medicine, not the title as such.
Practically: a Washington posting for a veterinary technician means the licensed role, and the protection behind it is regulatory rather than a named criminal offense.
“No individual, other than a licensed veterinary technician, may advertise or offer their services in a manner calculated to lead others to believe that they are a trained or licensed veterinary technician”
Both rules this page rests on — the task tables in WAC 246-935-050 and the supervising-veterinarian duties in WAC 246-935-040 — were re-issued together as WSR 26-07-008, filed March 6, 2026, effective April 6, 2026, replacing the tables that had stood since February 2016.
Every tier quoted here describes that current version, so re-check the chapter if you are reading this well after publication.
One recent change sits outside scope entirely: the Washington State Jurisprudence Examination was removed from initial licensing requirements effective July 28, 2025 — a credentialing change, not a scope change, and it alters no tier on this page.
The tables run well past the rows quoted above.
Table E also tiers diagnostics — blood pressure, cytology and basic hematology, ECG, fecal and urine analysis, skin scraping and CO2/O2 saturation, all indirect for the LVT and direct for the assistant — plus urinary catheter placement and nasogastric or orogastric tube placement, both assistant-prohibited.
Table H adds arterial and central venous catheters and blood administration (direct-tier LVT work, prohibited for the assistant) alongside plain IV catheter placement; Table I covers venipuncture and Table J ophthalmic testing, both indirect for the LVT and direct for the assistant; Table K covers enema, ear flush, massage, noninvasive CPR, controlled substances and ear tipping.
Emergency animal care under subsection (4) is indirect-tier work for both.
On imaging, the tables tier the acquisition of diagnostic images but contain no radiation-operator-permit provision; any such requirement would live outside WAC 246-935-050.

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.
Yes — under direct supervision.
Table A puts induction of anesthesia, intubation and maintenance of anesthesia all at direct supervision for the LVT: the supervisor on the premises and quickly and easily available (WAC 246-935-050, Table A).
The unregistered assistant is prohibited from inducing and intubating but may maintain anesthesia under immediate supervision, which for an assistant requires supervisor consultation and instruction.
Confirm the current table with the Washington board before scheduling anesthesia duties.
Only some, and at the tightest tier.
Table D allows the LVT single-root extractions — except canine teeth — under immediate supervision, and only where the extraction does not require sectioning of the tooth, sectioning of the bone, or incision of the gingiva (WAC 246-935-050, Table D).
Complex or surgical extractions are reserved to the veterinarian, and the assistant is prohibited from the extraction row.
Dental prophy is indirect-tier LVT work and immediate-tier assistant work.
Verify the current rule with the Washington board.
Yes.
Washington's table names closure — "suturing of prepared skin wound or gingival incision" — as a direct-supervision task for the LVT, and prohibits it for the unregistered assistant (WAC 246-935-050, Table B).
Removing sutures, drain tubes and staples is a separate row: indirect supervision for the LVT, direct for the assistant.
Surgery itself stays reserved except as the tables outline.
Confirm the current text with the Washington board.
Yes — under direct supervision, with the veterinarian on the premises.
Table E places euthanasia in the LVT's direct column and prohibits it outright for the unregistered assistant (WAC 246-935-050, Table E).
The assistant's animal-care list is wide, but it ends before this row: no inducing, intubating, closing wounds or performing euthanasia.
Ask the Washington board about any euthanasia protocol that does not fit the table's tiers.
A defined, tiered list.
Under immediate supervision an assistant may maintain anesthesia (with supervisor consultation), monitor a sedated or anesthetized patient, perform dental prophy and fine needle aspirates, and give intra-testicular blocks and IV injections in uncatheterized veins; under direct supervision, take diagnostic images, place IV catheters, remove sutures, give IM/SC injections and microchips, and administer vaccines — including rabies biologics — with the required certificates.
The assistant is prohibited from inducing, intubating, extracting teeth, centesis, euthanasia and controlled substances.
