As of August 2021, the national qualification system for veterinary nurses started being implemented in Korea. The first national qualification test produced certified veterinary nurses in February 2022. Veterinary nurses assist veterinarians in treating and caring for companion animals. This study investigated improvement suggestions for the current qualification system by pinpointing what was missing in this institution and analyzing exemplary cases in other countries regarding naming for veterinary nurses, national qualification systems and expertise levels, job responsibilities, and the work coverage in veterinary nurses. Under a constantly improving national qualification system, veterinary nurses can be leading professionals for pet animals’ health and well-being and contribute to better veterinary service as long as veterinarians collaborate with veterinary nurses who take on more responsibility in collaborative efforts.
