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.
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.

SOF IMO vs SilverZone iOM: which should your Class 6 child take?
SOF IMO and SilverZone iOM both test Class 6 maths, but the exam pattern, syllabus split, and scoring are different enough to matter. Here is a side-by-side comparison to help you choose — or why most families end up doing both.
SOF and SilverZone registration last dates 2026-27, explained for parents
Four school-route registration dates fall between 23 and 30 September 2026: if your school picks those sittings, SOF’s 30-day rule gives 23 September for a 23 October IMO, 27 September for a 27 October IEO and 30 September for a 30 October ISO, and SilverZone publishes 30 September 2026 for every paper. None of them is a form a parent fills in. Here is what each date means, what to ask the school, and where to go if the school is not entering your child.
