Using an empirical approach, this research investigates the effectiveness of an e-government system in the public education sector from the viewpoint of the schools management. The e-gov system implemented by educational authority is our target system. The updated DeLone and McLean IS success model’s six constructs—information quality, system quality, service quality, intention to use and usage, user satisfaction, and net benefits—was used to evaluate the educational solution’s performance as an information system. In order to measure the constructs implied by the model, a survey based on a likert scaled questionnaire was employed as research technique in this work. The empirical evaluation was carried out using exploratory, confirmatory factor analysis, and structural equation modelling. It was discovered that the research model was dependable and valid. The findings contribute to a deeper comprehension of the main success dimensions and how they interact by extending our grasp of the constructs used to gauge the e-gov system’s effectiveness. We talked about the ramifications of our work. Applied as well is the DeLone and McLean IS success model. On the other hand, data quantity and the usage of other methodologies analysis are regarded as the model validation’s flaws to some extent.
