One school, fourteen years, three programmes.

Children join at Pre-KG and most stay until the Diploma. The programme changes twice on the way and the fee steps up with it; the campus, the house and usually the class never change. Grade 12 is small on purpose — we cap the Diploma at sixty.

average Diploma points across 58 candidates. Four scored 43 or more. Forty-one are studying outside India, seventeen of them in Chennai, Vellore and Bengaluru.

Four houses, four rivers, one line.

Every child is sorted on the first day of Pre-KG and stays until Grade 12, siblings together. The house colour is the shirt, the boat and the notebook. The course of each river is drawn across its own colour below, in the order the four rivers run down Tamil Nadu — Palar dashed, because for most of its length it runs under the sand.

“We are a small school by choice. Nine students to a teacher means the teacher knows which one has not eaten breakfast, and eleven acres on a river means there is always somewhere to walk it off.”
