International Olympiad of Mathematics (iOM) Class 6: syllabus, dates and exam pattern (2026–27)

Everything you need in one place — the exact NCERT chapters this paper tests, its published exam dates, the registration window, and the full marking scheme. Updated for the 2026–27 session.

Last verified against SilverZone Foundation's own site on 18 August 2026. Exam dates re-checked on 24 August 2026.

SilverZone publishes these under the heading "Tentative Examination Schedule for the year 2026-27" — they are the body's own dates, but SilverZone has not marked them final, so treat them as indicative until your school confirms. SOF's dates, by contrast, are published as confirmed. One inconsistency worth knowing about: the schedule lists three dates, while the iOM page itself still describes a two-date structure ("the school may opt from the two dates suggested"). Ask your coordinator which of the published dates your school has actually opted for.

SilverZone also lists an online-mode sitting of iOM on 26 December 2026, under the same 30 September 2026 registration cutoff. It was added to SilverZone's own exam-date data on 11 September 2026; the dates above are its offline sittings.

Registration: SilverZone published one registration cutoff covering every paper it runs: 30 September 2026, on the same page it headed "Tentative Examination Schedule." SilverZone moved this date: its own exam-date endpoint returned 31 August 2026 on every read from 18 August to 1 September 2026 and 30 September 2026 from 2 September, with no announcement anywhere on its site. It falls weeks before the exam. Registration itself is through participating schools only, so the date is a deadline for your school, not for you: the school has to enter your child by then. Ask your coordinator now, or write to info@silverzone.org.

Free — deadline calendar

The deadline is set by your school, not by you

Most parents find the exam date and assume they have until then. The registration window closes long before it, and for some papers it has already started closing. Here is how it actually works.

  • Your school registers your child and your school picks which of the 2–3 dates the class sits. The family does not choose.
  • For SOF papers, registrations must reach SOF exactly 30 days before that chosen date — and once the school has chosen, the date cannot be changed.
  • Most bodies register through the school. These do not have to: CREST (online, no published cutoff), Unified Council — directly for NSTSE itself at ₹350 against ₹150 through a school, and on three online sittings, NSTSE-Online, UIMO-Online and UIEO-Online, at ₹354 each including GST — Indian Talent Olympiad on its individual online route (its own later dates — Slot 1 closes 30 October), and Humming Bird (online, ₹150 a subject, no published cutoff — its two dates are picked as you register). CREST is the simplest of them. SilverZone also runs an individual registration form alongside its default school route; which papers it offers we have not been able to confirm.

Closing next

  • SOF IEO (English) — if your school picks 27 October 2026

    Registrations must reach SOF by 27 September 2026

  • SilverZone Foundation — Every SilverZone paper

    Registration closes 30 September 2026

    The body publishes this date but has not marked it final — confirm with your school before treating it as fixed.

    Registrations must reach SOF by 30 September 2026

  • Indian Talent Olympiad (ITO) — School route — Set B

Frequently asked questions

Same Class 6 NCERT maths syllabus, different exam shape: iOM has fewer, higher-value questions (35 questions, 100 marks, 40 minutes) versus IMO's 50 questions in 60 minutes, and iOM's Scholar's Zone section carries more weight per question than IMO's Achievers section.
