The beginnings of Carmel School go back to the 1940s. In the year 1946 the Government espoused the policy of divulging education in the regional language. Some parents in the locality of St. Ann’s were desirous of getting English education for their children and in reality it was a collection of tuition classes conducted under the direction of Sister Leonilla A.C. in a small building on the campus known as the ‘Garden House’. As this ‘English School’ gained in popularity the Management decided to open an English Medium School in 1951 calling it Carmel English School.

In 1964 it was acknowledged by the Education Department and got the official approval for Std.I to VII and 12 years later the recognition was made permanent. With the winds of change and the desire of the parents to have the CBSE Syllabus NOC was procured from the State Government to change over to CBSE in August 2014 and in July 2015 the School obtained Affiliation up to Secondary Level, from the Central Board of Secondary Education, New Delhi.
