DEPARTMENT OF HEALTH
(Veterinary Board of Governors)
[Filed March 6, 2026, 8:24 a.m., effective April 6, 2026]
Effective Date of Rule: Thirty-one days after filing.
Purpose: Veterinary technicians and unregistered assistants; supervision and delegation of animal health care tasks from licensed veterinarians. The veterinary board of governors (board) is adopting amendments to animal health care tasks in WAC 246-935-050 to align Washington state with industry standards. The adopted amendments designate the animal health care tasks that may be delegated to veterinary technicians and unregistered assistants and the level of supervision that is required for each task. For readability purposes, the board has reformatted the rule to list individual tasks and the required level of supervision in a categorized table format.
The board is also adopting a new definition for "general anesthesia" and is updating the current definition of "immediate supervision" as related to unregistered assistants in WAC 246-935-010. These updates are consistent with and clarify amendments made to the animal health care tasks rule.
Finally, the board is adopting updates in subsection WAC 246-935-040 (2)(b) to strengthen the intent of the rule and move the language to the beginning of the section. The amendment clarifies the responsibilities of the supervising veterinarian in relation to the delegation of animal health tasks to veterinary technicians and unregistered assistants.
