Trade-offs
- !Premium fees (up to USD 35,020 in 2023-2024) put it out of reach for most local families
- !No IB Middle Years Programme - the middle-school curriculum is the school's own US-aligned model, not MYP
- !Day school only, with no boarding option for relocating or regional families
- !No published government inspection band, so external quality signals rely on accreditation alone
- !No official published fee schedule, so families cannot verify costs from the school directly
- !No explicit official statement of the language of instruction (English is inferred from delivery and EAL provision)
- !Day-only with no boarding option, limiting access for non-Mumbai or overseas families
- !Curriculum history includes a Cambridge phase for middle grades, which can cause confusion about current provision
