Top 10 International Schools in Mumbai

Mumbai's international sector is small in count and concentrated in quality. Around fifteen IB World Schools sit in the city; the top five take most of the parent attention and most of the published results. Beneath them sits a credible mid-tier producing strong IGCSE and DP cohorts without the headline fees.

This is a ranked top 10, built from published IB DP averages, IGCSE outcomes, CIS or NEASC accreditation, longevity, and recurring family signal. Fuller neighbourhood and commute detail sits in the Best international schools in Mumbai pillar.

The ranking

1. Dhirubhai Ambani International School

Dhirubhai Ambani International School at Bandra Kurla Complex is the headline school in India. The 2025 IB DP cohort placed 9th worldwide. ICSE and IGCSE run in middle school; sixth form consolidates on IB DP.

Around 2,800 students, ages 4 to 18. CIS and NEASC accredited. Published fees stretch from INR 1.7 lakh in the lower years to INR 10.2 lakh at senior level, with full-package senior fees reportedly reaching INR 97 lakh for some corporate-relocation contracts. Admissions are the most selective in Mumbai.

2. Oberoi International School

Oberoi International School in Goregaon East runs the full IB continuum across two campuses. The 2025 DP average was 35.5 against a global average of 30.58, and the Class of 2025 reported USD 8.1 million in university scholarships.

Around 2,906 students from 29 nationalities, ages 3 to 18. CIS and NEASC accredited. Senior-year fees of INR 5.6 to 8.9 lakh (about USD 7,000 to 11,000) make it the strongest value play among Mumbai's top schools. The Goregaon East location is practical for Juhu, Andheri West, and Malad; less so for South Mumbai.

3. American School of Bombay

American School of Bombay in BKC is the natural landing point for US corporate and diplomatic families. Founded 1981. Full IB continuum plus American-track elements, CIS accredited, around 1,300 students.

The 2024 IB DP average was 34, top score 41, mean subject score 5.34. Fees run INR 17.7 to 31 lakh (roughly USD 21,000 to 37,000), the highest senior-year band in the city. Calendar, sports, and pastoral culture follow the American international-school model; transitions from American schools elsewhere in Asia are smooth.

4. JBCN International School (Parel)

JBCN International School (Parel) was placed No. 2 in India and No. 1-2 in Mumbai by EducationWorld 2025. The Class of 2025 reported over USD 13 million in university scholarships. 100% IGCSE pass rate in 2025.

Around 700 students, ages 3 to 18. IB PYP, Cambridge IGCSE, IB DP. CIS accredited. Fees run INR 80,000 to 7.8 lakh, well below DAIS and ASB for comparable curriculum scope. Parel sits in central-south Mumbai; the Bandra-Worli Sea Link makes it accessible from the western suburbs.

5. Aditya Birla World Academy

Aditya Birla World Academy in Tardeo, South Mumbai, is No. 1 in the Times School Survey for international-curriculum schools in Mumbai. Cambridge Primary, IGCSE, and both A-Levels and IB DP at sixth form. CIS accredited.

Around 800 pupils, ages 2 to 18. 1:8 teacher-to-student ratio. Fees INR 8.4 to 18.4 lakh (about USD 10,000 to 22,000). The A-Level offering distinguishes it. Mumbai is overwhelmingly an IB DP city at senior level; ABWA is one of the few credible A-Level finishers in the international sector.

6. Cathedral and John Connon School

Cathedral and John Connon School in Fort is the school parents most often name by reputation alone. Founded 1860. ICSE primary, IGCSE plus IB DP at senior, with AP electives.

The 2025 IB DP average was 38.4, a pattern that has held across multiple cohorts. CIS accredited. Fees INR 2 to 6.7 lakh (roughly USD 2,500 to 8,000), unusually low for the results. The primary spine is ICSE rather than Cambridge, which matters for families planning a future move to a Cambridge-stream school abroad.

7. BD Somani International School

BD Somani International School in Cuffe Parade, South Mumbai, is the strongest South Mumbai pick on results. IGCSE plus IB DP. The most recent published IB DP average was 36.3 with an *IGCSE A/A rate of 63.2%**.

Around 600 students, ages 5 to 18. CIS accredited. Fees INR 5.6 to 12.6 lakh (about USD 7,000 to 15,000). The head is British-trained and the university-counselling reputation is strong. BD Somani finishes on IB DP only; an A-Level finish sits at Aditya Birla or Garodia.

8. Ecole Mondiale World School

Ecole Mondiale World School in Juhu was Mumbai's first full IB continuum school, founded 2004. PYP, MYP, and DP from Nursery to Grade 12.

Around 600 students, ages 3 to 18. CIS and NEASC accredited. Most recent published IB DP average 38. Fees INR 6.9 to 10.9 lakh (about USD 8,000 to 13,000), inclusive of textbooks, uniforms, and pool access. Juhu is one of the most sought-after residential areas for international families; the school sits inside that catchment.

9. Singapore International School Mumbai

Singapore International School Mumbai is one of the few credible Cambridge-plus-IB schools serving the far northern suburbs. CCLP ranked it 9th nationally in 2025-26.

Around 600 students, ages 3 to 18. Cambridge IGCSE plus IB DP, CIS accredited. Fees INR 6 to 8 lakh (about USD 7,000 to 10,000). The location works for Dahisar, Borivali, and the far western suburbs; it is impractical from BKC or South Mumbai on a daily commute.

10. Ascend International School

Ascend International School in BKC is deliberately small, around 400 students across PYP, MYP, and DP. Ranked jointly 2nd nationally by Cfore among day co-educational international schools in India.

Ages 3 to 18. Fees roughly INR 8 to 10 lakh (about USD 10,000 to 12,000). At 400 students across 14 year groups, class sizes are small and the school knows its families well. Facilities and extracurricular breadth are narrower than at the 2,000-plus-student schools. The BKC location overlaps directly with the corporate-package circuit.

How this list was built

The ten schools clear four filters.

Published results. Each school publishes either an IB DP average above the global mean (currently 30.58) or a strong IGCSE A*/A profile, or both. Press-release lines without an underlying number were not enough.

Accreditation. Nine of the ten hold CIS; four also hold NEASC. CIS does not certify teaching quality; it certifies the school has submitted to external review of governance, safeguarding, and learning. In a market where websites lean on awards, that is the cleaner signal.

Longevity. Schools that have run a senior cohort for several years sit ahead of newer entrants on similar results. A single strong cohort is not yet a pattern.

Recurring family signal. Where public data is similar, the tiebreaker is which schools come up repeatedly when Mumbai families describe the realistic shortlist.

Two exclusions matter. Hill Spring International and Bombay International publish credible work but with thinner sixth-form data. JBCN's other Mumbai campuses (Borivali, Oshiwara) run the same group academic culture; Parel is the strongest of the set.

How to use this list

A ranked list orders a shortlist; it does not pick the school. Three filters cut the ten down quickly.

Where you live. Mumbai traffic punishes a long school run more than fees do. From BKC, Bandra, or Andheri: DAIS, ASB, Ascend, Oberoi, Ecole Mondiale. From South Mumbai: Cathedral, BD Somani, Aditya Birla, JBCN Parel. From the far northern suburbs: Singapore International. Oberoi sits awkwardly for South Mumbai but is the strongest non-DAIS option from the western suburbs.

Fee bracket. DAIS at full package and ASB at senior level sit at the top. Oberoi, Cathedral, JBCN Parel, and Singapore International deliver strong outcomes at roughly half the fee or less. BD Somani, Ecole Mondiale, Aditya Birla, and Ascend cluster in the mid-band. Mumbai does not require top-tier fees for a genuinely good international education.

Curriculum. IB DP is the dominant senior qualification across the list. Aditya Birla is the strongest A-Level option among the ten. ASB carries the only meaningful American-curriculum infrastructure. Cathedral runs AP electives alongside IB DP and ISC. Families committed to a non-IB exit should narrow to that handful early.

FAQs

Which is the single best international school in Mumbai?

Dhirubhai Ambani International School at BKC, on IB DP results. The 2025 cohort placed 9th worldwide, the only Indian school in the global top ten. On a per-rupee basis, Oberoi International School is the strongest value play: DP average 35.5 in 2025 at roughly a quarter of ASB's senior-year fees.

Are these all IB schools?

Mostly. Nine of the ten run IB DP at senior level. Cathedral also offers AP electives. Aditya Birla runs both Cambridge A-Levels and IB DP at sixth form. ASB carries American-curriculum infrastructure alongside its IB programme. Pure Cambridge A-Level finishers are covered in the Best British schools in Mumbai brief.

How much do the top schools in Mumbai cost?

Senior-year fees range from about INR 6 lakh to INR 31 lakh (roughly USD 7,000 to 37,000). DAIS sits inside the lower published band on a base contract; full corporate-package fees can run materially higher. ASB sits at the top. Oberoi, JBCN Parel, and Cathedral all publish senior-year fees below INR 8 lakh with strong DP results.

How early should families apply?

For DAIS and Oberoi, early contact is sensible. Both have more applicants than places at popular entry years; families on confirmed relocation packages sometimes make contact before the move is finalised. For the rest, three to six months before a target start date is generally workable. Spaces at the top schools should not be assumed to be available on arrival.

What is missing from this list?

Two categories. Newer schools with strong early signal but only one or two senior cohorts on the board, including parts of the JBCN, Garodia, and Podar groups. Specialist schools for SEN, Francophone, Japanese, German, and other national-curriculum families. The pillar and the BKC area guide cover the wider field.
