A student information system (SIS) is a software application designed to manage student data and academic records. It helps schools and educational institutions track information such as enrollment, grades, attendance, and schedules. By centralizing this data, SIS makes it easier for administrators, teachers, and students to access and manage important information. These systems often include features like online portals for students and parents, allowing them to view grades and communicate with teachers. Additionally, SIS can streamline administrative tasks, such as reporting and compliance, making it a vital tool for efficient school management.
