Best IB Schools in Mumbai

Mumbai has the deepest IB DP market in India and one of the deepest in Asia. Around fifteen IB World Schools sit inside the city. The 2024 global IB DP average was 30.32. Mumbai's top tier finishes between 34 and the high 30s, with DAIS consistently in the global top 10.

The city is also where the Cambridge and IB sectors overlap. Several schools run IGCSE in the middle years and finish on IB DP at 18. A handful (Aditya Birla, Garodia, Podar) keep A-Levels as a parallel sixth-form option. ASB in BKC is the main American-anchored IB option.

Fees stretch across a wide range. ASB sits at the top by some distance, around USD 37,000 at senior level. Most strong IB schools land between USD 8,000 and USD 22,000 for the DP years. DAIS, despite its global standing, publishes one of the lower senior-year fees of the top tier; admissions, not fees, are the constraint.

The top tier

Dhirubhai Ambani International School

Bandra Kurla Complex. Ages 4 to 18. ICSE plus IGCSE plus IB DP. CIS and NEASC accredited. Around 2,800 pupils. Founded 2003.

Dhirubhai Ambani International School is the headline IB DP school in India. The 2025 cohort placed 9th worldwide for IB DP results, with perfect 45-point scores recurring year on year. The school runs ICSE alongside IGCSE in the middle years before consolidating on IB DP at sixth form.

Admissions are the most competitive in Mumbai and heavily assessed; sibling priority and entry-point cohorts (typically nursery and senior school entry) dominate. Published senior-year fees sit well below ASB and Aditya Birla. The waiting list, not the price tag, shapes the experience.

Cathedral and John Connon School

Fort, South Mumbai. Ages 3 to 18. ICSE plus ISC plus IB DP, with AP electives. CIS-accredited. Founded 1860. Around 1,200 pupils.

Cathedral and John Connon is the oldest school in this group by more than a century and one of the most reputationally entrenched in Mumbai. Senior school splits: some students finish on ISC, others on IB DP. The DP cohort averaged 38.4 in 2025 and 38.48 in 2022, a band held across at least four cohorts. AP electives sit alongside DP for US-bound students. Primary is ICSE rather than Cambridge. The Fort location is prized for prestige and hard for families based north of Lower Parel.

Ecole Mondiale World School

Juhu, Western Suburbs. Ages 3 to 18. Full IB continuum (PYP, MYP, DP) plus A-Levels. CIS and NEASC accredited. Around 600 pupils. Founded 2004.

Ecole Mondiale is the strongest full-continuum IB option in the western suburbs. The 2024 DP cohort averaged 38 points, with *52% A/A at A-Level** the same year. Dual CIS and NEASC accreditation. The school is small by Mumbai standards: tight pastoral access, narrower HL breadth than Oberoi or DAIS. Juhu works for Bandra, Khar, Andheri and Versova; less practical from South Mumbai or the eastern suburbs.

BD Somani International School

Cuffe Parade, South Mumbai. Ages 5 to 18. IGCSE plus IB DP. CIS-accredited. Around 600 pupils. Founded 2006.

BD Somani is the South Mumbai DP school with the tightest IGCSE-to-DP pipeline. Published IB DP average 36.30, *IGCSE A/A rate 63.2%**. The DP intake is small; the cohort feels closer to a sixth-form college than a large school, and HL combinations narrow accordingly. Cuffe Parade location, settled British-trained headship.

Strong mid-tier

Credible IB schools with published DP averages above the global mean and consistent IGCSE results. The gap from the top tier is real but narrower than the price suggests.

Oberoi International School

Goregaon East (and a JVLR campus). Ages 3 to 18. Full IB continuum. CIS and NEASC accredited. Around 2,900 pupils.

Oberoi International is the largest IB-only school in Mumbai and a strong source of university scholarship offers. DP 2025 average 35.5 against a global average of 30.58. USD 8.1M in university scholarships awarded to the 2025 cohort. PYP through DP runs across two campuses (Goregaon East and JVLR). Cohort size lifts HL breadth and athletic depth. Scale means a different feel from a small school like BD Somani or Ascend.

Jamnabai Narsee International School

Vile Parle, Western Suburbs. Ages 3 to 18. Full IB continuum plus IGCSE plus A-Levels. CIS-accredited. Around 1,500 pupils. Founded 1971.

Jamnabai Narsee International sits next to the larger Jamnabai Narsee School and runs the IB stream. DP 2025 average 34, with the highest score 45/45 and an average grade of 5.29 across 100 students. Cambridge IGCSE and A-Levels run alongside, giving families a multi-track senior school. The international stream shares a campus footprint with the much larger Indian-curriculum sister school, which shapes the day-to-day feel.

JBCN International School (Parel)

Parel, Central Mumbai. Ages 3 to 18. Full IB continuum plus Cambridge plus IGCSE. CIS-accredited. Around 700 pupils.

JBCN Parel is the strongest of the JBCN campuses and runs a clean PYP-to-DP pathway. EducationWorld ranked it No. 1 to 2 in Mumbai and No. 2 nationally in 2025. 100% IGCSE pass rate, USD 13M+ in university scholarships for the Class of 2025. Parel is commutable from both South Mumbai and the western suburbs. The chain runs other campuses in Borivali and Oshiwara; Parel is the DP flagship.

Singapore International School Mumbai

Dahisar East. Ages 3 to 18. Full IB continuum plus IGCSE. CIS-accredited. Around 600 pupils.

Singapore International School Mumbai is one of the few credible IB schools serving the far northern and western suburbs. CCLP placed it 9th nationally in 2025-26. PYP runs into MYP and DP; IGCSE sits alongside DP at senior level. Dahisar works for families based in Mira Road, Borivali and the northern suburbs, less so from BKC or South Mumbai.

Bombay International School

Babulnath, South Mumbai. Ages 3 to 18. PYP plus Cambridge plus IGCSE plus IB DP. Around 450 pupils. Founded 1962.

Bombay International School is the oldest international school in the city and one of the smallest in this group. CCLP 2025 placed it 8th in India. PYP runs in the lower school, Cambridge in the middle years, then IGCSE feeds IB DP. Small cohorts give close pastoral knowledge; HL subject breadth is narrower than at the larger schools.

Ascend International School

Bandra Kurla Complex. Ages 3 to 18. Full IB continuum. Around 400 pupils. Founded 2011.

Ascend International is the smallest of the BKC IB schools and runs a pure PYP-to-DP continuum. Cfore ranked it jointly 2nd among day co-ed international schools in India. No published CIS or NEASC accreditation, which is a gap to raise at admissions. BKC location, smaller cohort, younger institutional history (founded 2011); the academic signal so far is positive.

American School of Bombay

Bandra Kurla Complex. Ages 3 to 18. American Common Core plus IB DP plus PYP. CIS-accredited. Around 1,300 pupils. Founded 1981.

American School of Bombay (ASB) is the highest-fee school in the city by a clear margin and the main option for families who want an American-curriculum-into-IB-DP pathway. IB DP 2024 average 34, highest individual score 41, average subject score 5.34. Around 80% of grade-12 students sat the full Diploma; the rest took DP courses without the full Diploma, which is normal in American-curriculum IB schools and shifts the meaning of the cohort average. ASB is the most internationally diverse IB school in the city and the only one anchored on an American pre-DP design.

Best for full IB continuum (PYP plus MYP plus DP)

Eight Mumbai schools run PYP, MYP and DP in-house. Continuity matters less for academic outcome than for school experience: a student joining the DP from a non-IB middle school does not arrive at a disadvantage, as the Cathedral and DAIS pathways prove. It matters more for pedagogical consistency and family ease (no transition at 11 or 16).

The continuum schools, ranked by published DP results:

1. Ecole Mondiale: DP avg 38 (2024), Juhu, full continuum plus A-Levels.
2. Oberoi International: DP avg 35.5 (2025), Goregaon East and JVLR.
3. Jamnabai Narsee International: DP avg 34 (2025), Vile Parle.
4. JBCN Parel: top of EducationWorld rankings in 2025, DP figures not published.
5. Ascend International: ranked nationally by Cfore, DP figures not published.
6. Singapore International School Mumbai: full continuum, DP averages not published.
7. Kanakia International: full continuum, reported a 45/45 perfect score in 2023.
8. NES International: full continuum, 100% DP pass rate reported but cohort averages not published.

DAIS, BD Somani and Cathedral are excluded here: each runs ICSE or IGCSE in the lower or middle years rather than PYP or MYP.

The four IB programmes

Mumbai's IB sector is concentrated in two of the four IB programmes: the Primary Years Programme (PYP, ages 3 to 12) and the Diploma Programme (DP, ages 16 to 18). The Middle Years Programme (MYP) exists in continuum schools but competes with Cambridge IGCSE, which most parents prefer through 16. The Career-related Programme (CP) is rare; only Podar offers it.

The DP itself is the same six-subject plus core structure wherever it is taught:

• Six subjects across the six IB subject groups, with three at Higher Level (240 hours each) and three at Standard Level (150 hours each).
• The Diploma core: Theory of Knowledge (TOK), the Extended Essay (a 4,000-word independent research piece), and CAS (Creativity, Activity, Service).
• Subjects scored 1 to 7. Up to 3 bonus points for TOK and Extended Essay together. Maximum 45 points; 24 points is the pass threshold with conditions.

The 2024 global IB DP average was 30.32 points. Strong Indian IB schools finish well above this: DAIS in the 40s at the top of its cohort, Cathedral and Ecole Mondiale in the high 30s, Oberoi and BD Somani mid-to-high 30s. Indian DP cohorts skew high partly through admissions selection, partly through cultural emphasis on exam preparation.

PYP and MYP quality varies more between schools than the DP does. The DP is heavily externally examined; PYP and MYP rely on internal assessment against IB criteria, and the strength of the programme depends on teacher capacity and leadership at the specific school.

CIS (Council of International Schools) appears at most of the schools above and signals governance, safeguarding and learning audit rather than ranking. NEASC sometimes sits alongside CIS at the strongest schools (DAIS, Ecole Mondiale, Oberoi). For context, see accreditations explained and what is CIS accreditation.

How to choose between them

Five questions narrow the field faster than rankings.

Continuum or split pathway? A full PYP-MYP-DP continuum keeps the same pedagogy from age 3 to 18. A split pathway (Cambridge or ICSE in the lower school, IB DP at sixth form) is academically equivalent if the school is strong. Cathedral and DAIS prove the split model can produce top DP results.

HL subject availability. The DP requires three Higher Level subjects from three different groups. Smaller cohorts narrow HL options, especially in sciences. Oberoi, DAIS and ASB carry the broadest HL menus; BD Somani, Ascend and Bombay International narrow accordingly.

Where the family lives. Mumbai traffic shapes school choice more than fees do. South Mumbai schools (Cathedral, BD Somani, Bombay International, Hill Spring) work from Cuffe Parade to Worli. BKC schools (DAIS, ASB, Ascend) cover Bandra and BKC. Western suburbs schools (Ecole Mondiale, Jamnabai Narsee, Podar, Oberoi Goregaon) cover Juhu, Andheri, Vile Parle and Santacruz. Singapore International at Dahisar and Oberoi JVLR cover the northern suburbs.

Published results versus marketing. DAIS, Cathedral, Ecole Mondiale, BD Somani, Jamnabai Narsee, Oberoi and ASB publish detailed cohort averages. Several do not. An absence of published results is not proof of weak performance, but it shifts the burden onto admissions conversations. See IB results in Mumbai for the ranking by published DP averages.

Sixth-form pathway flexibility. Aditya Birla, Garodia and Podar finish on both A-Levels and IB DP, preserving the option to switch at 16. Pure IB DP schools (Oberoi, Ecole Mondiale, Ascend, JBCN Parel) commit the family to DP from MYP onward.

FAQs

Which Mumbai school has the highest IB DP average? Dhirubhai Ambani International School (DAIS) in BKC. The 2025 cohort placed in the global top 10 for IB DP results, with reported cohort averages in the 40s. Cathedral and John Connon (38.4 in 2025) and Ecole Mondiale (38 in 2024) sit in the next band.

What does it cost to send a child through IB DP in Mumbai? Senior-year fees range from around INR 6.5 lakh at Podar to INR 31 lakh at the American School of Bombay. Most strong IB schools fall between INR 8 lakh and INR 18 lakh per year at DP level, which is roughly USD 9,500 to 22,000 at 2026 rates. Add registration, capital fees and exam fees on top.

Is the IB harder than ICSE or CBSE? Different rather than harder. The DP demands six subjects plus TOK, the Extended Essay and CAS, so the workload is broader. ICSE and CBSE narrow earlier and rely more on memorisation in the final years. Top DAIS or Cathedral students perform strongly in either system; the question is structural fit, not difficulty.

Do Indian universities accept the IB Diploma? Yes. Indian universities including Delhi University, Ashoka, Symbiosis, FLAME and the IITs (via the JEE) accept IB Diploma scores, usually with a conversion table to percentage. Some Indian universities convert generously, others less so. Most IB DP students from Mumbai apply abroad (UK, US, Canada, Singapore, Australia) where the Diploma is recognised at face value.

Which IB schools in Mumbai offer the full PYP plus MYP plus DP continuum? Ecole Mondiale, Oberoi International, Jamnabai Narsee, JBCN Parel, Ascend International, Singapore International School Mumbai, Kanakia International and NES International. The other strong DP schools (DAIS, Cathedral, BD Somani) run ICSE or Cambridge in the lower or middle years.

Is a continuum school better than a Cambridge-into-IB DP school? Not necessarily. The Diploma cohort at Cathedral and the Diploma cohort at DAIS both consistently outperform most continuum schools in Mumbai despite running ICSE and IGCSE earlier. A strong DP programme does not require PYP or MYP underneath it. What matters is whether the pre-DP design (whatever the label) builds the independence and breadth the DP demands.
