In the context of China's education reform, the education group emerges as a new form of school organization designed to equalize access to high-quality educational resources. While this increasingly popular mode of school running has achieved notable results in Beijing, Shanghai, and Hangzhou, among other cities, there are concerns about the problems it engenders, such as severe homogenization and poor group management. The purpose of this paper is to examine the causes, outcomes, and problems of education groups and to propose solutions to existing problems, as well as to provide references for future school alliance development.
