This research examined alumni involvement as institutional stakeholders at Tarlac State University (TSU), including their participation in governance, decision-making, policy and program formulation, and project implementation. Since they provide financial donations, mentorship, and strategic counsel that shape institutional growth, alumni are widely recognized as significant donors to higher education institutions worldwide. Although there has been widespread informal alumni engagement in the Philippine setting thus far, the desire to include alumni in governance should be suitably institutionalized. A descriptive quantitative research approach was used for the study, and 381 TSU alumni were polled between 2000 and 2025 using a stratified random sample technique to ensure that alumni from all colleges participated. Alumni organizations were found to be successful models of accountability, transparency, governance, and alignment with the institution’s objectives. Due to their frequent consultation in decision-making, alumni have a comparatively moderate amount of impact. Their participation in the creation of policies and programs, which included outreach initiatives, board test preparation, career mentoring, and scholarships, was highly regarded. Alumni participation in development-focused projects was substantial, particularly in the areas of infrastructure, legal aid, and extension services. The degree of involvement varied greatly throughout the colleges, with the College of Public Administration and Governance and the School of Law having the highest levels of interest. Little formal procedures, uneven presence among universities, and a lack of an advanced feedback structure were among the hurdles encountered in an attempt to overcome these unfavorable outcomes. The study concludes that alumni can have a significant impact on TSU governance and recommends formalizing sustainable and participative engagement strategies to strengthen alumni’s influence on university life.
