Do you have to have a 2 year degree to be vet tech?

Yes, most states require that you have a 2-year degree in veterinary technology and have passed at least the Veterinary Technician National Exam and often a state exam in order to work as a veterinary technician.

To find out the requirements for the state in which you live, you should contact your state veterinary technician association or whatever group in your state credentials (licenses, registers or certifies) veterinary technicians.
