St. Mary's High School - Mazgaon

St. Mary's School was founded in 1864 by members of the Society of Jesus (Jesuits), a Roman Catholic religious order founded by St. Ignatius of Loyola in 1540. The school is located adjacent to St. Anne's Church which was established in 1860. The school began as a Catholic school of education and a military orphanage. Later it opened to the Catholic populace in general, which led to expansion and to the construction of the building that now houses the senior school, whose foundation stone was laid by Lord Linlithgow, the Viceroy of India from 1936 to 1943.[4] At present, the school has four Gothic-style buildings and is divided into Senior School (grades 5 and above) and Junior School (grades 4 and below). The school offers various sports facilities to the students, which include a gymnasium, basketball arena, and two grass turfed football grounds.

In 1933, St. Mary's High School SSC was carved out of the main St. Mary's School – which at the tie offered the British General Certicate of Education to offer students the opportunity to focus on completion of the Secondary School Certificate.[5] St. Mary's switched to the ICSE Indian Certificate of Secondary Education curriculum in the year 1958 – thereby, becoming one of the early adopters of the system.[6] The school re-commenced offering the Indian School Certificate diploma (equivalent to the Cambridge A-Level) in 2021.
