Dhirubhai Ambani International School

In Brief

If academic pedigree and IB results are your primary filter, DAIS is in a class of its own in Mumbai - the 9th best IB school in the world in 2025. If your child is in the younger years or on the ICSE track, the fee-to-result ratio is worth scrutinising before committing.

DAIS sits at the top of Mumbai's international school landscape by one clear measure: IB results. Ranked 9th globally for IB Diploma performance in 2025 - the only Indian school in the world top 10 - it draws families from across the city and from relocating corporate households who want a credential that travels. The multi-curriculum structure (ICSE, IGCSE, IB Diploma) means children can enter at any stage without switching schools.

The BKC campus is purpose-built and well-resourced: labs, drama studios, sports facilities, and a strong co-curricular programme through Round Square membership. Teacher quality at the senior end is generally regarded as strong, with consistent IB subject outcomes. The school's alumni placement record at Ivy League and top Asian universities is well documented on their site.

The catch is the fee structure's steep jump at Grade 8. ICSE fees stay modest at around INR 1.85 lakh, but IGCSE leaps to INR 5.9 lakh and IB Diploma hits INR 9.65 lakh - roughly US$116K at current rates, making it one of Mumbai's most expensive schools at the senior end. Some families also find the culture fairly pressured and competitive; worth asking how the school handles students who are strong but not Oxbridge-bound.
