The three Set dates are the school route — the school picks one set and the child sits the paper with the class. The two slot dates are the individual online route a family can take without the school, and they are different dates, not alternatives to the same sitting. Indian Talent Olympiad publishes the online dates as tentative, stating that "the final exam schedule will be updated 20 days prior". Once a set or slot is selected it cannot be changed.
Registration: Through the school, registration closes on three published dates: 31 August 2026 for Set A, 10 October 2026 for Set B and 10 November 2026 for Set C. The school collects ₹175 per student per subject, remitting ₹150 to ITO and keeping ₹25 for organising costs. Directly, without the school, individual online registration for Classes 1 to 10 closes 30 October 2026 for slot 1, at ₹500 per subject — one of only four direct routes across the bodies we cover, alongside CREST, Unified Council's NSTSE and Humming Bird. The 31 August school cutoff is the earliest registration deadline of the season across every paper we track, and the later individual date does not extend it.
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 for NSTSE (₹350 direct against ₹150 via school), 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.

Exam pattern
How the ITO-S paper is structured
| Section | Questions | Marks per question | Section total |
|---|---|---|---|
| Section 1 — Subjective (syllabus) | 35 | 1 | 35 |
| Section 2 — Logical Reasoning | 10 | 1 | 10 |
| Section 3 — Higher Order Thinking (HOTs) | 5 | 1 | 5 |
| Total | 50 questions | — | 50 marks · 65 minutes |
All 50 questions carry one mark, including the five Higher Order Thinking questions, so the paper is not weighted toward its harder end. Section 2's ten reasoning questions are a fifth of the marks and come from no science book — series completion, coding-decoding, blood relations, direction sense, Venn diagrams, mirror and water images, figure matrices, ranking, and cubes and dice. Indian Talent Olympiad does not publish a current-class versus previous-class split.

Indian Talent Olympiad publishes thirteen Class 6 science chapters: Physical Quantities Of Measurement, Motion, Light, Electric Circuits, Magnetism, Living Organism And Its Classification, Substances In Daily Use, The Cell, Movement In Living Beings, Food And Nutrition, Compound And Mixtures, Changes Around Us and Classification Of Materials. Four of those thirteen have no chapter in the 2026-27 Curiosity book at all: light, electric circuits, the cell, and changes around us in the reversible-versus-irreversible sense. Two of the four are physics, and the cell is an entire biology unit that now sits in Class 8. A Class 6 child revising only Curiosity has prepared for nine of the thirteen. It runs the other way too — Curiosity now teaches temperature, the states of water, natural resources and the solar system, none of which appear on ITO's Class 6 list. This is the second body in two days whose published Class 6 science syllabus predates the current book: CREST's list has the same shape. The mapping in the table above is ours rather than ITO's, since the body publishes topic names with no map to the new book.
