Parent fit
Families comparing STBS against other ICSE schools in Kolkata usually weigh three things: how the school handles the transition between primary and senior school, the strength of the co-curricular calendar, and how transparent the admissions team is during the enquiry. If you're choosing between State board and ICSE for the long-term exit, factor in the colleges your child is most likely to apply to — that decision often settles the board question more cleanly than a side-by-side feature comparison. Use the Compare tool on the platform to stack STBS against one or two finalists on board, fees, facilities and parent ratings before booking the campus visit round.
