IB Results in Mumbai

Mumbai has the deepest IB DP market in India, with roughly twenty-two IB World Schools running the Diploma inside the city. The 2024 global IB DP average was 30.32. Every Mumbai DP school that publishes a cohort number sits above the global mean, often by five points or more.

Dhirubhai Ambani International School (DAIS) in Bandra Kurla Complex is the standout. The 2025 cohort placed 9th globally for IB DP results. Perfect 45-point scores recur year after year, and the cohort average sits in the low 40s in years where the school publishes one. DAIS is the only Indian school routinely inside the global IB top ten.

Below DAIS, Mumbai splits into a publishing tier and a non-publishing tier. The first group puts cohort averages, pass rates and highest scores on the website. The second offers the Diploma but does not publish the numbers.

Ranked by published DP average

The schools below publish a cohort average for at least one recent year. Where a school publishes multiple years, the most recent average is shown. DAIS publishes a global ranking rather than an average, so it sits at the top as a separate entry.

Global average for context: 30.32 points (2024). Cohort sizes vary widely; smaller cohorts move the average more than teaching quality usually does.

A few notes on what the table does and does not show. DAIS publishes a global ranking and individual top scores but not a cohort average in the same format as the others. Treat the global-top-ten placement as the headline. Cathedral's 38.48 figure is from 2022; the 2025 cohort came in at 38.38, so the band is stable rather than a one-off. BD Somani's 36.30 is from 2021, the most recent figure on the school's own publishing record. Edubridge publishes a 2024 average of 36 but on a smaller cohort than the others in this band.

How to read these numbers

A DP cohort average reduces a whole year group to one figure. Three things distort that figure more than teaching quality does.

Cohort size. A 36 from 100 students means something different from a 36 from 12 students. Jamnabai Narsee's 34 (2025) sits on 100 students. BD Somani's 36.30 sits on a much smaller intake. Both are honest; they are not directly comparable.

Entry selection. Schools that filter students before the Diploma post higher averages. DAIS, Cathedral and BD Somani assess heavily before granting a Diploma seat. Schools with open DP access carry weaker performers and post correspondingly lower means. A school producing 34 on a non-selective intake is doing more work than a school producing 38 on a filtered one.

Full Diploma versus DP courses. ASB reports around 80% of grade-12 students sat the full Diploma in its most recent published cohort. The rest took DP courses without the full Diploma, normal in American-curriculum IB schools. The published average reflects the full-Diploma group, not the year group, so it is not strictly comparable to a school where every grade-12 student sits the full Diploma.

Schools with no public DP results

The schools below run the IB DP but do not publish a cohort average. The Diploma exists; the headline number does not.

• Ascend International School (BKC). Cfore ranked jointly 2nd among day co-ed international schools in India. Cohort numbers are not on the public site.
• Singapore International School Mumbai (Dahisar). CCLP placed it 9th nationally in 2025-26.
• Bombay International School (Babulnath). CCLP 8th in India 2025.
• JBCN Parel. EducationWorld No. 1-2 Mumbai 2025; USD 13M+ in university scholarships for the Class of 2025. No published cohort average.
• Kanakia International School. Reported a 45/45 in the 2023 cohort but no full cohort average.
• Podar International School. 100% DP pass rate for 18+ consecutive years, but no published cohort mean.
• NES International School. 100% DP and IGCSE pass rates with World and Country Toppers reported; year-by-year averages not published.
• Hill Spring International (South Mumbai). DP plus Cambridge; no cohort average.
• Hiranandani Foundation School. ICSE results detailed; DP averages not published.
• Mainadevi Bajaj International. IGCSE results detailed; no DP cohort average.
• DSB International School (Cumballa Hill). German-English DP school; no public cohort average.

An absence of a published cohort average is not evidence of weak performance. Several of these schools rank highly in third-party tables (EducationWorld, CCLP, Cfore, Times) where the methodology weights more than DP results. It does shift the burden of proof onto the admissions visit.

A reasonable question at the open day: "What was last year's DP cohort average, the highest score, and the cohort size?" The first two have been the same questions for thirty years. The third tells you whether the average is a reliable signal.

FAQs

Which Mumbai school has the highest IB DP average? Dhirubhai Ambani International School in BKC. The 2025 cohort placed 9th globally for IB DP results, with cohort averages reported in the low 40s in years where the school publishes one. Cathedral and John Connon (38.38 in 2025) and Ecole Mondiale (38 in 2024) sit in the next band.

What is a good IB DP average? The 2024 global average was 30.32 points. Any school averaging 33 or above is performing meaningfully above the global mean. Mumbai's publishing schools all sit at 34 or above, which puts them in the upper tier internationally.

Why do some Mumbai IB schools not publish results? There is no IB requirement to publish. Schools with strong, stable cohort averages tend to publish; schools with smaller cohorts or open-access DP intake more often share results privately during admissions. The absence is information, not proof of weakness.

Are Mumbai IB scores comparable to scores in Singapore or Dubai? Yes. The DP is the same global exam. Mumbai's top tier (DAIS in the low 40s, Cathedral and Ecole Mondiale in the high 30s, Oberoi mid-30s) sits in the same band as Singapore's strongest IB schools (UWCSEA Dover 36.7, Tanglin Trust 39.6). Dubai's top IB schools cluster around 36 to 38. The benchmark is the global average of 30.32.

What about IB schools that finish on A-Levels or AP as well? Cathedral runs AP electives alongside the DP. Aditya Birla and Podar offer A-Levels in parallel. ASB students take AP through grade 11 before consolidating on the IB DP. A school's published DP average usually reflects only the students who sat the full Diploma, so the cohort behind the number can be a subset of the year group.
