Gartner defines student information system (SIS) software as a service (SaaS) as a core system of record for higher education institutions that serves as the central hub for storing, organizing and processing student academic and administrative activities. The SIS supports student, faculty and staff-facing functionality, including management of information assets, while also supporting back-end administrative functionality. SIS SaaS is delivered under a pay-for-use basis or as a subscription license model (with regular updates), where application support and infrastructure provisioning and management are the responsibility of the vendor.
