According to the introduction of the Ministry of Education, first-class universities are divided into two categories: A and B. It is hoped that through this way, first-class universities will be urged to speed up the reform and development of colleges and universities, and those listed as B will face up to the gap and catch up.
Among the six B universities, Northeastern University, Hunan University and Northwest A&F University were all on the "985" list before, while Xinjiang University, Yunnan University and Zhengzhou University were not 985 universities.
The Ministry of Education evaluates all kinds of universities every year, including education level (mainly lectures), teaching staff (doctoral supervisors, master supervisors, professors, national scientists), the number of international and national award-winning papers, the construction of libraries and collections, the establishment of colleges and departments, campus construction (including land occupation and beautification), hardware construction, etc. Invention patents, employment comparison, etc.
So there is a standard of class A, class B and class C in the evaluation. Class A is a national key school, followed by class B, and class C is a secondary college. Therefore, Class A is a national key university, which is superior to other schools in terms of knowledge learning, education level and good employment. Every year, the state announces the key disciplines of national colleges and universities. It's important to take an A-class school, but it's also important to take an examination of a country's key subjects.
