In an era marked by rapid technological progress and social shifts, the pursuit of sustainable development has become an urgent necessity for the global community. Within the framework of the global agenda, universities have begun to play a key role, using their profound influence on the younger generation and the academic sphere as a whole to form a culture deeply rooted in the principles of sustainable development. In general, alumni associations serve as crucial channels bridging the gap between the academic world and society. It is for this reason that the authors have set out to assess the effectiveness of alumni associations through the perspective of two different generations of graduates: young graduates and representatives from the earliest cohorts. Using a qualitative research approach, which includes in-depth interviews and expert evaluations, this study aims to assess the key criteria for an effective alumni association. The resulting data, supported by mathematical analysis and stakeholder theory, not only shed light on the success criteria for alumni associations but also offer practical recommendations for enhancing their contribution to sustainable development. The research conducted within the context of a Kazakhstani university provides valuable insights and practical strategies for integrating sustainable development into the economic and managerial structure of the academic sphere, setting a precedent for universities worldwide.
