The implementation of academic information systems plays an important role in improving educational administration. One such system is e-Rapor, which supports student assessment, report card generation, and academic data management. However, challenges related to system quality, information quality, and user satisfaction may affect its effectiveness. This study aims to examine the effects of System Quality and Information Quality on User Satisfaction, as well as the effect of User Satisfaction on the Effectiveness of Academic Management in the implementation of e-Rapor at Pasundan Jatinangor Vocational High School. A quantitative survey was conducted involving teachers, homeroom teachers, the e-Rapor operator, and the vice principal for curriculum. Data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results indicate that System Quality and Information Quality significantly influence User Satisfaction, with Information Quality having the strongest effect. In addition, User Satisfaction significantly improves the Effectiveness of Academic Management. The novelty of this study lies in extending the DeLone and McLean Information Systems Success Model by operationalizing Net Benefit as Effectiveness of Academic Management, providing a more context-specific framework for evaluating educational information systems in vocational schools.
