DAIS Mumbai’s IB Track Record: Is the Hype Backed by Numbers?

For the May 2027 session, DAIS reported an average of 40.8 points, its highest ever, against a global average of 30.88. Of the 105 students, 104 were Diploma candidates. The school’s results page also lists: dais

• 13 perfect scores of 45, and 16 students on 44 dais
• 77 students (75%) at 40 points or more, and 91 students at 36 or more dais
• 28% of the class in the top 1% of IB candidates worldwide dais
• 87% of Higher Level papers graded 7 or 6 dais

India’s national average was 32.78 in 2027, so DAIS sits about 8 points above the country. careers360

The seven-year mean is about 40.1, and no year fell below 39.4. Details worth knowing:

• 2021: 73% of students scored 40 or above and the average was 41.1. DAIS’s own yearbook notes that the 2021 IB Diploma examinations were cancelled by the boards, so treat this year as an outlier. daisdais
• 2023: The average was 39.4 against 30.24 worldwide and 31.95 for India. 57% of students scored 40 or above, versus about 8.55% worldwide. dais
• 2025: All 110 Diploma candidates were awarded the Diploma, a 100% pass rate against a global 81.26%. dais

The ranking, read precisely

DAIS ranked ninth among IBDP schools worldwide in the 2027 Education Advisers UK rankings, the only Indian school in the global top 10. Two details add context: businesstoday

• The eighth-ranked school scored 41.0 and the tenth scored 40.7, so the margins at the top are very thin. businesstoday
• DAIS has the largest cohort among the top 10, which makes a ~40.8 average harder to sustain. businesstoday

Three takeaways:

1. Pathways is the only other IB-focused school on your list with a published IB figure. TrueMaths states its 2025 IB DP average was 33.54. That is about 5.9 points below DAIS’s 39.4 for the same year. It also cites a global average of 30.32, which is the 2024 figure. The 2025 global average was 30.58. Doing the comparison against the correct figure, Pathways is still about 3 points above the world, but DAIS is about 8.8 above. truemathsibo
2. Doon, Mayo and Rishi Valley don’t publish IB averages on the pages provided. Only Doon offers the IB Diploma, and only as an alternative to ISC. An IB-score comparison with them isn’t possible.
3. Fees differ with the model. DAIS is a day school, while Doon, Mayo and Rishi Valley are boarding schools. Some TrueMaths fee figures are also internally inconsistent: Mayo’s header shows ₹10.53 lakh but its fee table shows ₹11.52 lakh and its FAQ shows ₹6,84,300. Confirm all fees with each school directly.

What the numbers don’t tell you

1. Selective intake. The TrueMaths DAIS page says the school prioritises academic performance, and admission is extremely competitive. High results partly reflect who gets in, not only what the school adds. truemaths
2. Self-reported data. The global averages DAIS compares against are independently verifiable. The 2026 figure matches the 30.88 reported by TES. The school-level numbers come from DAIS itself. tes
3. Small-cohort swings. Perfect scores fell from 11 in 2023 to 5 in 2025, then rebounded to 13. With about 105 students, small changes move the headline numbers.
4. Loose claims online. The TrueMaths DAIS page says DAIS is among the top 20 IB schools worldwide. That is consistent with older DAIS brochures, but the 2026 rank is ninth. The same page also lists the school’s application fee as both ₹5,000 and ₹8,000, and its header labels the board “CBSE” although the affiliations listed are ICSE, IGCSE and IB. truemaths
