On the day the school began, 36 girls joined the boarding house and started their studies. In 1903, the construction of a new school building was completed. In 1906, the school came under government regulations and began receiving grants.
In the same year of its establishment, Sri. Poonkuzhi Ramavaryar of Thrissur joined the school as a teacher, earning the distinction of being the first graduate teacher of the institution. He was also the first Headmaster of this school.
With emphasis on the sacred goal of education — to shape global citizens who believe in tolerance, fraternity, equality, and peace — the Headmasters who served here until 1926 were Sri. Poonkuzhi Ramavaryar, Sri. Kongad Achuthan Nair, and Sri. C.P. Vaidyanath Iyer.
They were followed by a dedicated line of Headmistresses: Sr. Ludwica, Sr. Beatrice, Sr. Mary Bernard, Sr. Mary Teresita, Sr. Margaret Mary, Sr. Seela, Sr. Domitilla, Sr. Moses, Sr. Caritas, Sr. Alexandriya, Sr. Gentil, Sr. Piyusha, Mrs. V.J. Lilly, Mrs. Annie M.V., Sr. Lisjo, Sr. Anna Antony, Sr. Stella Rose, Sr. Agnes, and Sr. Jitha Paul. Through their professional excellence, modern outlook, and insightful leadership, the 125-year-long journey of the school stands radiant and memorable, and is remembered with deep gratitude.
Mrs. M.P. Anithacher, who upheld the institution’s noble tradition and led it to greater heights of success, received the National Award for Best Teacher in 2002.
Through continuous efforts rooted in prayer, hard work, and dedication, students of this institution receive life training year after year. The present Headmistress is Sr. Sibiya Theresa.
St. Mary’s actively engages in all areas essential for the holistic development of students. The school promotes excellence in arts, sports, literature, and science, and is actively involved in Guides, Red Cross, Karate, KCSL, DCL, Social Service, and various other co-curricular activities.
