Laboratory animal science is a supporting discipline for many fields such as life science, medicine and pharmacy. The level of employees from laboratory animal science is not only related to the standardized development of laboratory animal industry, but it also affects the scientific and technological innovation and industrial development of biomedicine and other fields and is involved in biosafety and social civilization. Therefore, the training and qualification system of employees in laboratory animal science is very important. We investigated the training processes of laboratory animal employees in Europe, the United States, Japan and China, including the standards, classification, grade, training content and level evaluation. The training system for laboratory animal technicians and doctors is relatively developed, while the training system of domestic laboratory animal managers needs to be established. However, there is a general lack of training and evaluation systems for laboratory animal researchers worldwide. Therefore, the establishment of an evaluation system suitable for the self-development of laboratory animal researchers is analyzed and suggested.
