Which Olympiad is best for a Class 1 or Class 2 child?

Start with one Olympiad in the subject your child enjoys most. Maths (IMO) is the most popular first choice. Class 1 and 2 children take Level 1 only, so treat it as a fun first exam, not a race.

Can parents register their child for an Olympiad directly?

For SOF Olympiads, no. Registration goes through the school's Olympiad coordinator. If your school doesn't take part, ask whether a nearby school can host your child. Other organisers have their own rules, so check with them.

Is there negative marking in Olympiads for Classes 1–5?

There is no negative marking in SOF Level 1 papers, so children should attempt every question.

Do Olympiad marks count towards school marks?

No. Olympiads are separate competitions. They don't affect school marks or report cards.

SOF, Silverzone, Unified Council or Hindustan Olympiad: which should we choose?

Choose by subject and by what your school offers, not by the organiser. All of them test the school syllabus plus reasoning, so the same preparation works for each.

Olympiad Exams for Classes 1–5 in India: IMO, NSO, IEO and More, Explained

Which Olympiads can a Class 1–5 child take, how does registration work, and what do the exams actually test? A plain-English guide for parents.

If your child's school has sent home an Olympiad registration form, you are probably wondering which exams are worth it, what they test, and how much preparation a 7- or 9-year-old really needs. This guide covers the Olympiads most primary-school children in India take, and how to prepare without turning it into extra tuition.

What is an Olympiad, for a primary-school child?

School Olympiads are subject competitions held in schools across India. The best known are run by the Science Olympiad Foundation (SOF). They are not board exams and they do not affect school marks. Their value is the kind of thinking they reward: reading a question carefully, spotting patterns, and applying a concept to a situation the child hasn't seen before.

The main SOF Olympiads for Classes 1–5

IMO (International Mathematics Olympiad): maths and logical reasoning.
NSO (National Science Olympiad): science and logical reasoning. Some SOF pages now list it as ISO.
IEO (International English Olympiad): grammar, vocabulary, reading and spoken/written English.
NCO (National Cyber Olympiad): computers and logical reasoning.
IGKO (International General Knowledge Olympiad): general knowledge and current affairs.

Every one of these has a reasoning or "Achievers" component, which is why logical reasoning practice pays off across all of them.

Other Olympiads your school may offer

SOF is the biggest organiser, but many schools also run Olympiads from other organisers. Preparation is the same for all of them: the school syllabus plus logical reasoning.

Silverzone Olympiads: maths, science, English and more, for Classes 1–12. Top performers in Level 1 can qualify for Level 2.
Unified Council: best known for NSTSE (science and maths), plus English and computer Olympiads, for Classes 1–12.
Hindustan Olympiad: run by the Hindustan newspaper group in Uttar Pradesh, Uttarakhand, Bihar and Jharkhand, for Classes 1–12. Classes 1–10 cover maths, science, English, GK and logical reasoning.

Dates, fees and patterns differ by organiser and change every year, so check with your school's coordinator or the organiser's own website.

How registration works

SOF Olympiads are registered through schools, not by individual parents. Your school's Olympiad coordinator collects names and fees and picks one exam date from the options SOF offers. If your school doesn't take part, ask the coordinator whether a nearby school can host your child.

2026-27 Level 1 dates

Schools choose one date per exam from SOF's published options:

IEO: 30 September, 27 October or 17 November 2026
IMO: 23 October, 26 November or 10 December 2026
NSO / ISO: 30 October, 19 November or 3 December 2026

So for many children, the IMO and NSO exams are still 3 to 6 weeks away. Check your school's chosen date and work backwards.

Level 1 and Level 2

Level 1 is the school-based round everyone takes. For Classes 3 and above, top performers qualify for a Level 2 round, usually held around February. Classes 1 and 2 take Level 1 only.

What the papers look like

Level 1 papers are multiple-choice, pen-and-paper, and 60 minutes long, with no negative marking. Classes 1–4 typically answer 35 questions and Class 5 answers 50. The last section, the Achievers Section, carries more marks per question and has harder, multi-step problems.

Which Olympiad should my child take?

Start with one. For a first Olympiad, pick the subject your child enjoys most. A good first experience matters more than the number of exams.
Maths and science are the most popular pair. IMO and NSO share the reasoning section, so preparing for one helps with the other.
Don't stack four exams in one month for a Class 1 or 2 child. Little and often beats cramming.
SOF or another organiser? Choose by subject and by what your school offers. The organiser matters far less than steady practice.

How to prepare at home (without making it a chore)

10–15 minutes a day of mixed practice is better than a long weekend session.
Talk through the wrong answers. Ask "why did you pick that?" The reasoning behind a mistake tells you more than the score.
Do one timed paper a week in the last month, so 60 minutes doesn't feel long on exam day.
Read the question twice. Most Olympiad mistakes at this age come from misreading, not from not knowing.
