What St. Mary's ICSE, ISC & International School Mumbai does

St. Mary's ICSE, ISC & International School Mumbai is a 161-year-old Jesuit educational institution founded in 1864, located on Sardar Balwant Singh Dhody Marg in Mazagaon, South Mumbai. Managed by The Bombay St. Mary's Society Trust and affiliated with the Council for the Indian School Certificate Examination (CISCE), the school operates as a non-profit serving boys from Jr.KG through Class 10 under the ICSE curriculum, with a higher-secondary ISC wing (Commerce and Science streams) opened in 2020, and a newly introduced Co-educational International Wing affiliated to the IGCSE Curriculum launched in 2025 for Classes 1 and 3 with planned extension to Jr.KG and Class 2. The institution is governed by Jesuit leadership under Director Fr. Yohan Alphonso S.J. and Principal Elias Coelho.

The school's product portfolio combines core academic curricula with distinctive enrichment programs: the C4 Programme (Conscience, Competence, Commitment, Compassion) for character development; the Irobokid robotics curriculum with iProto (robot building, sensors) and iCode (SCRATCH graphical programming) levels; international student exchanges with partner schools in France (Lycee Jean Paul II, St. Gilduin High School Combourg) and Nepal (St. Xavier's Godavari); and the student-organized Immaculata inter-school festival attracting 18+ schools. The school maintains an active digital presence through its website, social media channels, and the myclassboard mobile application for fee payment and parent communication.

Revenue is generated exclusively through recurring annual tuition fees and one-time admission fees, with payments processed via the myclassboard.com platform. The school follows a direct-to-consumer go-to-market approach via an online admissions portal with designated enrollment windows (typically November-December for the following academic year). Distribution is entirely through the single Mazagaon campus serving Mumbai-area families. Notable outcomes include consistent top ICSE board examination rankings, MSSA football championship wins, and CISCE Zone-A tournament participation. The school is consistently ranked among India's top 10 schools (Education World 2020) and top 50 in Mumbai (Times School Survey 2020).
