This paper introduces the ParSU Web Portal for Online AACCUP Accreditation (ParSU-WebPOA), a web-based system developed at Partido State University (ParSU) to enhance the accreditation process of the Accrediting Agency of Chartered Colleges and Universities in the Philippines (AACCUP), Inc. Crafted through a descriptive developmental approach to research, the study focuses on web design, development, and evaluation. By utilizing cloud storage services, ParSU-WebPOA centralizes access to AACCUP survey instrument documents while granting document owners control over viewing and downloading permissions. Designed as a generic system for State Universities and Colleges (SUCs) lacking a dedicated web system, this standardized solution offers value to educational institutions seeking an efficient and user-friendly online accreditation platform. Regarding system evaluation, the study employed the Technology Acceptance Model (TAM) to evaluate user perceptions. The results indicate a strong consensus on the system's usefulness and ease of use, with anticipated improvements in job performance, productivity, and effectiveness. However, these results are limited to Partido State University. Given the system's potential utility for other SUCs, the study suggests conducting simultaneous testing with users from diverse institutions to gather their feedback and integrate the findings into future enhancements. Nevertheless, the results presented in this study can already serve as an indicator of the potential success of the system's implementation, benefiting both educational institutions and the AACCUP accrediting body.
