Abstract

This study evaluates the success of a university enrollment web portal through a predictive modeling approach that integrates the Unified Theory of Acceptance and Use of Technology (UTAUT) and the DeLone and McLean Information Systems Success Model (ISSM). Although higher education institutions increasingly deploy digital portals to support academic services, technical availability alone does not ensure user satisfaction, sustained use, or perceived institutional benefits. This study therefore examined the factors influencing user satisfaction, continuance intention, and net benefits in the context of the NEMSU enrollment portal. A mixed-methods design was employed, with quantitative data gathered from 176 students, faculty, and staff and analyzed using Structural Equation Modeling through WarpPLS 8.0. Qualitative inputs were used to contextualize users’ experiences and support the interpretation of the quantitative findings. The results showed that system quality did not significantly influence user satisfaction, whereas information quality and service quality were strong predictors. User satisfaction significantly influenced continuance intention, while facilitating conditions and self-efficacy emerged as important drivers of sustained portal use. Mediation analysis further confirmed that continuance intention mediated the relationship between user satisfaction and net benefits. The findings suggest that university ICT administrators should prioritize accurate and timely enrollment information, responsive support services, reliable facilitating conditions, and user training to strengthen self-efficacy. The study contributes to the predictive validation of a hybrid UTAUT-ISSM model and provides practical guidance for improving sustainability, continuance adoption, and success of user-centered portals in higher education.
