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.
Registration: SilverZone published one registration cutoff covering every paper it runs: 31 August 2026, on the same page it headed "Tentative Examination Schedule." It was the earliest deadline on this site, and it fell weeks before the exam. Registration itself is through participating schools only, so the date was a deadline for your school, not for you: the school needed to have entered your child by then. SilverZone has published nothing since about late entries or an extension. If your school hasn't registered, ask your coordinator whether it made this date, or write to info@silverzone.org to check whether a late registration is still possible.
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. Four 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 the four.
