This study assesses and ascertains the relationship between university infrastructure and student satisfaction, emphasizing how facilities influence students' academic experiences and overall well-being. Using a convergent parallel mixed-methods approach, the research collected quantitative and qualitative data from over 1,600 students across 13 colleges in one state university in the City of Malolos, Bulacan, Philippines. The survey evaluated student satisfaction in five categories: library and learning resources, IT and digital services, student support services, health and wellness facilities, and recreational spaces. Findings revealed high satisfaction in areas like library cleanliness, student portals, medical services, and grievance handling procedures. However, notable deficiencies were identified in Wi-Fi reliability, digital resource accessibility, comfort room conditions, and canteen facilities. Thematic analysis of qualitative feedback echoed these concerns and highlighted additional needs for improved ventilation, lounge areas, and inclusive recreational spaces. ANOVA analysis showed significant differences in satisfaction based on college and year level, suggesting disparities in infrastructure quality and service delivery across colleges. Considering the strategic investment in infrastructure, particularly in digital services, sanitation, and inclusive spaces, it becomes pivotal for enhancing student satisfaction and academic outcomes. With this, effective improvement includes regular restroom maintenance, upgrading Wi-Fi infrastructure, expanding study and lounge areas, and ensuring standardized support services across colleges. These efforts are critical to creating a learning environment that supports student engagement, performance, and holistic development.
