TGT stands for Trained Graduate Teacher — a teacher qualified with a graduate degree plus a teaching qualification such as a B.Ed, who usually takes the middle and secondary grades, around Classes 6 to 10. The role sits below PGT (Post Graduate Teacher) and above PRT (Primary Teacher) in the common school hierarchy. The split mainly reflects which grades and subjects a teacher is assigned.
In Indian schools
TGT, PGT and PRT are staff roles a school assigns, each linked to the batches and periods that teacher takes. RaivatEdu models staff with role-based access enforced in the database, so each account is scoped to what that role needs.
