St John's High School is a school in Bangalore, Karnataka, India. It is one of the oldest schools in the city. The school is managed by a duly constituted Board of Management. The Chairman of the Board is the Bishop of the Karnataka Central Diocese of the Church of South India. The Members of the Board are drawn from the fields of finance, education, administration, social services etc.
The school's motto is "Nil Desperandum, Semper Fidendum" which is Latin for "Never despair, always have faith". St. John’s had some outstanding music teachers, among who was Ms Fewkes, who could pound out heavenly music on the piano. Her rendering of the School song in the early to mid sixties was a treat for the ears and soul.
St John’s was a co-educational Middle School (until 9th Std) till 1962 - being a feeder school to Bishop Cottons Boys/ Girls School. As a High School it limped along until Dec 1965 when the 3rd batch of High School students took the A.I.S.S.C exams (10th standard). When the results were announced, Peter Selvarajan their school topper obtained the First Rank in Karnataka ahead of the best students from the other English medium schools: Bishop Cottons, Baldwins, Clarence, St. Germain, Francis Xavier, and his photograph came out in the Bangalore Deccan Herald news paper. He was also awarded the National Merit Scholarship by the Govt. of India the following year. The school received a flood of congratulatory letters and applications for admission. The School was thus established among the leading English medium schools of Bangalore.
