St. CHARLES HIGH SCHOOL is a Religious Unaided Minority Institution as envisaged under Art. 30 (1) of the Indian Constitution. This institution was established in 1996 by the Sisters of St. Charles Borromeo. It caters to the education primarily of the Catholic community, yet from the very beginning the school has been open to all communities irrespective of caste or creed. The School is managed by the Allard Educational Society, Bangalore, registered under the Mysore Societies registration Act No. 17 of 1960.

The Congregation of the Sisters of St. Charles Borromeo was founded in 1684 by Fr. Adrien Bresy, Parish Priest of Wez ( Diocese of Tournai, Belgium ) to impart Christian education to the poor children of his parish.  The year 1684, the foundation year of the Sisters of St. Charles coincided with the death centenary of St. Charles Borromeo.  Therefore, Fr. Adrien Bresy pointed to St. Charles Borromeo, the illustrious cardinal of Milan, who had inspired him and whom he admitted, who had the same ideals and the same spirit as he who followed the hard and narrow way to reach the heights of sanctity, as the patron of the new born congregation.  He wished that the Sisters would follow his footsteps, live up to his ideals and be guided by his way of life.
