In the context of the ongoing expansion and democratization of tertiary education, the nurturing function of university student communities has attracted growing attention. This paper examines and synthesizes the synergistic effects of ideological and political education in higher education student communities in terms of character inculcation, value leadership, and demonstration and motivation. In order to achieve a more comprehensive and in-depth understanding of the synergy between ideological and political education and the all-in-one student community service platform, a set of evaluation index indicators is established, utilizing the refined hierarchical weighting approach for weighting purposes, and appraised through a multi-level fuzzy assessment framework. The results indicate that the universities under investigation exhibit adequate coordination between ideological and political education and the all-in-one student community service platform, with a comprehensive evaluation score of 3.74, and the scores of character inculcation, value leadership, and demonstration and motivation are all above 3.5, and statistically significant variations were observed across the dimensions of students’ gender, grade, and specialization (p < 0.05), specifically, the evaluations of male students, first year students, and science and engineering undergraduates register higher average scores. From character inculcation to value leadership to modeling and motivation, the pedagogical mission of the all-in-one student community service platform in colleges and universities permeates every key node of students’ growth.
