Extended data:

The "Nine Schools Alliance" has opened up a new situation of talent training and played a demonstration and leading role in talent training in China. After the establishment of the alliance, "exchange students" will be extended to domestic universities, that is, undergraduates from the alliance universities want to take a course in another alliance university.

As long as he applies to the academic affairs office of the other university, the other university will consider replying to his application according to factors such as the number of students. If the application is successful, students can go to another university to study. After completing the credits, he will return to his original university, which will recognize his course scores and credits.

The alliance will promote teachers. For example, if a course in a university is not well taught, many students will apply for the best teachers in this course in nine universities, which will bring pressure to the teachers who teach this course and promote their improvement.

In addition, according to the "Nine Schools Alliance" agreement, each school encourages its own students to apply for graduate students from other universities in the alliance, and also encourages graduate students to pursue doctoral degrees from other universities in the alliance, which has a certain effect on solving the phenomenon of "inbreeding" in colleges and universities to some extent.
