Graduate education is located at the top of national education, enrollment is the beginning of the top, which has always been the high ground for universities to compete for high-quality students. Recommended exemption students have absolute autonomy to choose, and universities may not hinder or restrict them for any reason or in any way. They can usually get the olive branch of multiple schools at the same time, and eventually choose the best, and go to the most desired school hall, but this will inevitably cause a lot of waste of the university’s indicators. In addition to the limitations of discipline strength, geographical location, economic development and other problems, the number and quality of public health and preventive medicine postgraduate enrollment in western China are even less dominant. By reviewing the development context of graduate recommendation exemption system, this paper clarifies the current situation of the public health and preventive medicine promotion and exemption enrollment in western China, and formulates a series of effective recommended enrollment measures such as expanding publicity channels, improving the ratio of reexamination, and optimizing the selection process, so as to provide references for all enrollment units to improve the quantity and quality of the promotion and exemption enrollment.
