To do a good job of school ideological and political work and ideology work in the Internet era, it is especially important to integrate the organic integration of Civic and Political teaching and student management. This paper takes H city as an example and establishes an evaluation index system for student management and informationalization of ideological and political teaching. After normalizing and quantifying the indicators, the entropy weight method is used to solve the weights of the indicators, and the coupling coordination degree model is established to judge the integration level of the two informatizations. To investigate the integration factors of the two, the gray correlation coefficient and the degree of correlation between the indicators are derived using the gray correlation method. The results show that the average annual growth rate of the integrated development level between the two is 4.42% and 8.15% during 2011-2020, and the coupling degree is higher on the whole, with an average of 0.8994, and the coupling degree of coordination is also on the trend of increasing year by year. The gray correlation between the two is high, in which the correlation between the working mechanism of cooperative education in the informatization of the work of Civic Teaching and the quality of practice indicators and student management reaches 0.7806 and 0.7876. To diversify, it is necessary to develop the integration of student management and Civic Teaching based on the research in this paper.
