No, veterinary assistants are not licensed professionals in any state in the US. In fact, no state requires any level of education or training for veterinary assistants. This is an entry-level position in a veterinary facility and training is usually done on-the-job. There are courses offered at high schools and many "institutes of higher learning" to certify veterinary assistants but the quality of the education/training may vary greatly. This is because many programs are taught by instructors who have no veterinary medical background. If a person wishes to take a course or courses in veterinary assisting, choosing a program that is taught by a veterinary professional, approved by a veterinary medical association or offered by a college that also offers an American Veterinary Medical Association accredited veterinary technology program would be a good idea. Veterinary assistant courses are basic vocational training courses will not prepare you to sit for the credentialing exams to become a veterinary technician in any state. Certification of veterinary assistants is also no legally recognized in any state.

No state in the US has educational or training requirements for a veterinary assistant. This is an entry-level position for veterinary staff and training is generally done on the job. There are some schools that offer veterinary assisting programs and "certify" their students however many of these are not overseen by an veterinary professionals or professional organizations and are often taught by people with no education or experience in the veterinary field. For people interested in enrolling in a veterinary assisting program, a wise choice would be to select programs offered by colleges that also offer an American Veterinary Medical Association accredited veterinary technology program or a veterinary assisting program that has been designed or approved by a veterinary professional association.
