Singapore International School Mumbai, almost always shortened to SIS, is one of the international options families consider in the far north of the city, and it appears on our Mumbai city hub. It teaches a Singapore based curriculum in the primary years that moves into the Cambridge IGCSE and then the IB Diploma in the senior years, and it is unusual in Mumbai for offering boarding alongside day places. It sits in the mid to premium band of the city market.
This profile is an independent reference page. GlobalSchoolGuide does not accept payment for coverage, and SIS Mumbai appears here because it is a real school relocating families ask about, not because it paid to be listed. We researched the facts below from the school and public sources at the time of writing, and mark anything we could not confirm as not published.
At a glance
Curriculum and academics
SIS Mumbai runs a staged international pathway. The early and primary years follow a Singapore based curriculum, drawing on the IB Primary Years approach and a Reggio Emilia influence in the youngest classes, before a pre IGCSE stage in classes 7 and 8 prepares students for the Cambridge IGCSE in classes 9 and 10. The senior school then takes the two year IB Diploma Programme in classes 11 and 12, with its six subject groups, the extended essay, theory of knowledge and the creativity, activity and service strand.
The combination gives a recognised route from primary school to a globally accepted school leaving qualification, with the IGCSE as a broad middle stage and the IB Diploma as the final step into university. Families weighing the senior choice can read our IB curriculum guide to understand how the Diploma is structured, and the British curriculum guide for how the IGCSE works as the stage before it.

Singapore International School Mumbai fees
SIS Mumbai sits in the mid to premium band on our Mumbai international school fees guide, below the very top IB names in the city but a clear international commitment, with tuition rising through the school as the IGCSE and IB Diploma years carry the highest cost. Boarding, where a family chooses it, is charged on top of tuition. Treat published figures as bands rather than a quote and confirm the current schedule with the school, since tuition is revised every year.
Tuition is only part of the budget. Expect a one time admission charge payable when a place is taken, and a refundable deposit at some stages. Examination fees for the Cambridge IGCSE and the IB Diploma fall due in the relevant years and are billed separately, and boarding, transport, meals, uniform and trips add to the annual figure. Use the School Finder and compare tools to weigh the full cost of a day or boarding place against other shortlisted schools.
Admissions
SIS Mumbai follows the Indian academic year, and entry is possible at most stages from Kindergarten upward, subject to availability in the relevant class. The school asks for the standard documentation and a record of prior schooling, with an age appropriate interaction for younger children and assessments for older applicants joining the IGCSE or the Diploma. Families considering boarding should raise it early in the process, as places are limited.
Because the senior programmes are structured, IGCSE and Diploma entry are easier confirmed at the start of a stage than part way through, and mid year places cannot be relied upon. Families relocating to Mumbai should apply as early as possible, ask the admissions team directly about day and boarding availability in the specific class and confirm the timing of the IGCSE and Diploma intakes.
Location and who goes there
The campus sits in Dahisar in the far north of Mumbai, close to Mira Road on National Highway 8, on a site of around eight acres with sports fields, a swimming pool, laboratories and boarding houses. The northern location places it within reach of the western suburbs and the growing residential belt north of the city, and the boarding option extends its catchment well beyond Mumbai to families placing a child from elsewhere in India or overseas.
The intake mixes local families in the northern suburbs and Mira Bhayandar with boarding students from further afield and some expatriate households drawn by the Singapore linked curriculum and the rare offer of boarding in the city.
