Student Information System (SIS), noun. Software that stores and manages the cumulative student record — demographics, enrollment, attendance, grades, and transcripts — and serves as the official system of record for a school, district, college, or university. Distinct from broader school management or education ERP platforms, which add finance, HR, library, and operations modules around the SIS.
glossaryPage.howItWorksTitle
An SIS is organized around the student record as its root entity. Each student row anchors related child records: enrollments (course or class registrations), attendance events, grades and assessments, family and contact data, and uploaded documents such as immunization forms or transcripts. Access is role-based — a registrar can edit demographics, a teacher can only update grades for their own sections, a parent sees only their child. Reporting exports feed state and federal compliance pipelines (in the US, EDFacts and state SIS files). Integration with a Learning Management System happens through education-data standards such as SIF (Schools Interoperability Framework), Ed-Fi, and IMS Global OneRoster, which sync rosters, course codes, and grade passback automatically.
glossaryPage.whySchoolsTitle
The term "student information system" emerged in the 1980s when mainframe and minicomputer registrars (PeopleSoft Campus Solutions, Banner) replaced paper card files. The 2000s SaaS wave (PowerSchool, Infinite Campus, Ellucian) moved the SIS to web-based, multi-tenant hosting. Adoption is mandatory in most jurisdictions because regulators require it. In the United States, FERPA defines the student educational record and mandates auditable access controls; in the European Union, GDPR adds consent and right-to-erasure requirements. Most US states require electronic SIS exports for funding, accountability, and graduation reporting under the federal Common Education Data Standards (CEDS) maintained by the National Center for Education Statistics (NCES). An SIS is therefore not an optional convenience — it is the institutional system of record.
glossaryPage.keyFeaturesTitle
- Cumulative student record — single root entity holding demographics, identifiers, and history across years
- Enrollment and scheduling — course registration, section assignment, and academic calendar tracking
- Attendance — daily and period-level attendance with codes for excused, tardy, and unexcused absences
- Gradebook and transcripts — assessment entry, grading scales, GPA calculation, and official transcript output
- Parent and student portal — role-based read access to grades, attendance, and contact information
- State and federal reporting — exports conforming to CEDS, EDFacts, and state-specific SIS file formats

What is the difference between an SIS, an SMS, and an SIS-LMS integration?
An SIS (student information system) is narrow: it owns the student record and academic history. An SMS (school management system) is broader and bundles the SIS with fees, HR, library, transport, and hostel modules. An SIS-LMS integration is the data pipe between the SIS (system of record) and an LMS (Moodle, Canvas, Blackboard) that delivers courses — usually exchanged over the IMS Global OneRoster or Ed-Fi standard.
What does it mean for an SIS to be the "system of record"?
System of record means the SIS holds the authoritative version of a data element — if the SIS and any other system disagree on a student's birth date, enrollment status, or final grade, the SIS value wins. Under FERPA, the educational record stored in the SIS is also the legally protected record subject to parental access and amendment rights.
Which data standards do SIS platforms support?
The three dominant K-12 interoperability standards are SIF (Schools Interoperability Framework, the oldest), Ed-Fi (an open data standard maintained by the Ed-Fi Alliance and widely adopted by US state education agencies), and IMS Global OneRoster (focused on roster and grade passback between SIS and LMS). Higher-education systems also use IMS LTI and the PESC XML transcript standard.
Does the same SIS work for a 500-student school and a 50,000-student district?
Generally no. A 500-student private school can run a lightweight SIS module inside an open-source ERP such as OpenEduCat and meet every operational need. A 50,000-student district needs multi-school hierarchy, state-reporting connectors certified by the state education agency, single sign-on with district identity providers, and a service-level agreement covering peak enrollment windows — typically PowerSchool, Infinite Campus, Skyward, or a hosted Ed-Fi-certified platform.
