UDISE+
Unified District Information System for Education Plus — the national system where every school in India submits school-level and student-level data each year.
UDISE+ collects data on schools, enrolment, teachers and infrastructure, and student-level profiles. Schools typically update student data each year through the portal, including details such as gender, date of birth, social category, mother tongue and disability type for children with special needs. The PEN (Permanent Education Number) is generated through UDISE+.
Because there is no public API, school software prepares and checks the data and produces files in the portal's layout.
