This research focuses on efforts to develop a web-based school management information system aimed at improving the efficiency of education administration. In today's digital era, many educational institutions still face various obstacles in managing data and information effectively, both in academic, financial, and reporting aspects. Reliance on manual systems in the administrative process causes delays in data processing, decreases the level of information accuracy, and limits transparency in education governance. Therefore, information technology-based innovations are needed that can integrate all education management processes more quickly, accurately and efficiently. This study used the Systematic Literature Review (SLR) approach to examine various previous research results related to the development of web-based school management information systems. Through this approach, researchers identified, selected, and analyzed literature that met the criteria of academic relevance and validity. Data from various sources were then thematically analyzed to find common patterns, benefits, and challenges in the application of web-based systems in the educational environment. The results show that the implementation of a web-based school management information system can significantly improve the efficiency and effectiveness of education administration. The system plays an important role in integrating data management of students, teachers, finances and reporting automatically, while supporting transparency, speed of access and accuracy of information. However, this research still has limitations in the number of sources and the relatively narrow scope of the study. Therefore, further research with an empirical approach and a broader field study is needed to strengthen the findings. Overall, the results confirm that web-based school management information systems have great potential to realize modern, transparent and sustainable education governance.
