The school was built to serve the interests of the Anglo-Indian Community and the children of military personnel and government pensioners.
R. Posnett, an Anglican clergyman, was sent to look after the spiritual interests of the Europeans and the Anglo Indians in the Cantonment area.
In the morning it was used as a school for children; in the afternoon as a library and a reading room and on Sundays for public worship.
When the CSI came into being in 1947 the school and church came under the jurisdiction of the erstwhile Mysore Diocese and the property was transferred to the CSITA.
The school's motto is "Nil Desperandum, Semper Fidendum" which is Latin for "Never despair, always have faith".
