St. Germain High School was founded in January 1944 by Late. Rev. Thomas Pothacamury,  the then Archbishop of Bangalore. The school was named after Rev. Fr. Germain, a much loved French Priest, who was on the staff of St. Joseph’s High School, which incidentally had also been housed in the same premises till it was shifted to the Museum Road.
The school is a private, unaided, minority educational institution, administered by the Archdiocesan Board of Education of Bangalore.

The academic year of the School was from January to December. In 1978 it was changed to June to April to fall in line with the rest of the country.

Being an Anglo-Indian School, it has a number of staff and students from this community. However, admission is open to Children from all religions and communities without discrimination.

The school prepares students for the Indian Certificate of Secondary Education (ICSE). Imparting value-based education is one of its main objectives.

The school motto is  “Ad Augusta Per Angusta : Triumph Through Trials”.
The School is situated on top of the  St. John’s Hill with Coles Park on one side and  St. Francis Xavier’s Cathedral on the other. The main entrance to the School was from St John’s Church Road and through the playground. This gate was closed and the main entrance shifted to Promenade Road in 1976 so that the games field is made use of, fully.

It is the only Anglo-Indian School maintained by the Board and is affiliated to the Council for the Indian School Certificate Examination. New Delhi.
