In school administration, DEO stands for District Education Officer — the government official responsible for administering and supervising schools across a district, including recognition, inspections and implementation of education schemes. The exact title and powers vary by state. (In data-entry contexts the same letters can mean Data Entry Operator, which is a different role.)
In Indian schools
Inspections and official reporting go more smoothly when a school can produce accurate enrolment, attendance and staff records on demand. RaivatEdu keeps that information current in one system, so responding to the district office is not a scramble through spreadsheets.
