— This research focuses on evaluating the software quality of five key information systems at Sacred Heart School–Ateneo de Cebu (SHS-AdC): Admissions, Grading, Finance, Human Resources, and Registrar. Utilizing the ISO/IEC 25010:2011 quality standard, the study examines critical attributes such as functional suitability, performance efficiency, compatibility, usability, reliability, and maintainability. A descriptive quantitative methodology was adopted, with surveys administered to 205 stakeholders, including faculty, non-teaching staff, and administrators. The results reveal that while the systems demonstrate moderate effectiveness in terms of functional suitability, they fall short in several other quality attributes. The Registrar and Human Resource systems were found to be particularly weak, especially in usability and reliability. In contrast, the Grading and Finance systems performed better but still presented challenges related to scalability, interoperability, and accessibility. These deficiencies significantly hinder operational efficiency and reduce overall user satisfaction. By systematically evaluating these systems using ISO/IEC 25010, the study provides a detailed understanding of their strengths and weaknesses. The findings offer valuable insights for guiding targeted improvements to enhance system quality and support the institution’s operational goals.
