Richard Cobbe was appointed chaplain to the British East India Company's Factory in Bombay.

In 1718, he founded a small school where twelve poor boys were given free housing, clothing, food, and education.

The school, which had one teacher, was located in a building not far from the present-day Cathedral of St. Thomas in Fort, Mumbai.

Archdeacon George Barnes, also with the East India Company, realised that the original school could not possibly meet the needs of hundreds of children it then looked after.

At the other end of the school stands a fourteen-storey building which houses the kindergarten classes, and staff quarters, along with the woodwork room.

In between the two buildings lie a hall (used for morning assembly and school functions), a tennis lawn, a basketball court, and a children's playground.

The students are divided among four houses, and compete through the year in extracurricular activities: Students called Prefects are appointed by the school to perform duties like monitoring classes when there is no teacher in the class or being involved in flag hoisting during Independence Day.

Boys, up to the 7th grade, wear white shorts, white half-sleeved shirts, school belt, black shoes, and the school tie (which is dark bottle green with a thin yellow stripes running diagonally).

The college boys wear a deep green full pant and a shirt which has a yellow coloured logo of the school on the pocket.

Some of the faculty live on campus, in apartments located in a building which also house the kindergarten school classes.

As part of their House duties, teachers oversee the selection and training of students for participation in inter-house activities.
