Abstract. This study evaluates the sustainability initiatives at San Pablo Colleges and their correlation with perceived institutional effectiveness using the Triple Bottom Line model. It examines economic, social, and environmental sustainability, governance, and continuous improvement through a descriptive-correlational quantitative design. Data were collected from 129 college stakeholders via a validated survey, with composite means computed for each sustainability domain. Findings indicate that social sustainability is the institution’s strongest area, emphasizing inclusivity and equity, while governance and leadership also score positively, reflecting effective decision-making. However, environmental sustainability received the lowest rating, highlighting opportunities for improvement in ecological practices. Institutional effectiveness, particularly stakeholder satisfaction with customer service, registered a high composite mean. Correlation analysis (r = 0.87) revealed a strong positive relationship between sustainability efforts and perceived institutional success. The study recommends enhancing environmental initiatives, increasing stakeholder engagement, and expanding sustainability training to align institutional practices with global standards. By fostering a culture of continuous improvement, San Pablo Colleges can strengthen its commitment to sustainability and institutional excellence.
