Rev. Mother Marie Louise Demeester, Foundress of the Belgian Missionary Canonesses of St. Augustine, with an undaunted Zeal and strong faith in God, sent three of her valiant Missionaries Mothers Marie Henriette Nollet, Gabriela De Spiegeleer and Elisa to serve the downtrodden of the coastal village Valiyathope, Thiruvananthapuram. Their arrival in 1924 marked the foundation of St. Roch's Convent. Realizing the importance of  Education in bringing about social change, tireless efforts were made to teach children and empower women. In June 1925, the Missionaries who were affectionately called by the people of the locality as 'Mothers', obtained permission to start a Primary School for Girls and an English Middle School for Girls with Preparatory class and Form I.

The people of the locality experienced and believed that they could be healed from the contagious diseases through the intercession of St. Roch's. Respecting the belief and desire of the people the convent and schools were named after St. Roch's. In response to the felt need of having competent and committed teachers, the 'Mothers' started a Training School for Girls in 1935. They believed in the dictum "when we train a man, we form only an individual, but when we train a woman, we form a society".

This was the humble beginning of this pioneer, and one of the oldest Teacher Training Institutions in India. Students from different parts of the state of Travancore underwent training. As a mustard seed, the smallest of all the seeds grows up and becomes the biggest of all plants; it has grown up and is rendering yeoman service to humanity for the past seventy-five years.
