IMO vs NTSE vs Other Maths Olympiads in India: A Parent's Map

"Which olympiad should my child write?" is a fair question with a confusing answer, because India has a lot of them — some run by schools, some by private organisations, some by the government, and one that leads all the way to an international team.

Here is a plain map of the main ones, who they suit, and how they connect.

The two families

Broadly, competitions split into two kinds:

School-registered olympiads — run by private organisations, conducted inside your child's school, multiple-choice, open to almost everyone. These are the ones most Indian children encounter.

Selection-track olympiads — a national pipeline that eventually selects India's team for the international competition. Far more difficult, subjective answers, and starting from higher classes.

Confusing the two causes most of the disappointment we see. They are different things with different purposes.

School-registered olympiads

These are conducted at school, usually in one or two levels, and are open from Class 1 upwards.

Who they suit: almost any child from Class 3 upwards who enjoys maths. They are a good first competition because the format is familiar and the pressure is low.

What they are not: a route to the international team. That is a separate track.

NTSE and scholarship exams

The National Talent Search Examination is a government scholarship exam, not a maths olympiad — but families often group it with them.

• Written in Class 10
• Two papers: mental ability and scholastic aptitude, so maths is only part of it
• Two stages: state level, then national
• Leads to a scholarship, not a competition team

Who it suits: strong all-round students in Class 10. Preparation overlaps heavily with olympiad reasoning work, which is one reason earlier olympiad practice pays off later.

The selection track to the international olympiad

This is the serious pipeline, and it starts later than most parents expect.

1. First stage — a screening test, typically from Class 8 upwards
2. Second stage — a longer, subjective paper requiring written proofs
3. Training camp — a residential camp for those selected
4. International team — a handful of students represent India

The key difference: from the second stage onwards, answers are written arguments, not multiple choice. A child must prove why something is true, not merely find it.

Who it suits: students from Class 8 or 9 who genuinely enjoy hard problems and are willing to spend serious time on them.

How they connect

Think of it as a ladder, not a set of alternatives:

• Classes 3–5 — school olympiads for exposure and confidence
• Classes 6–8 — school olympiads plus deliberate work on reasoning and number theory
• Class 8+ — the selection track becomes possible for keen students
• Class 10 — NTSE, drawing on the same reasoning skills

A child who does school olympiads from Class 3 arrives at Class 8 with exactly the habits the harder track needs. One who starts at Class 8 cold usually finds it a shock.

Choosing for your child

Ask three questions:

1. Does my child enjoy puzzles, or only school maths? Enjoying puzzles points towards olympiads. Being good at school maths alone does not necessarily.

2. What is the goal? Confidence and exposure → school olympiads. Scholarship → NTSE. Genuine competition → the selection track.

3. How much time is realistic? Two hours a week suits school olympiads. The selection track needs considerably more, and it should be the child's own choice, not the parent's.

Our guide to preparing for a maths olympiad covers the practical week-by-week side, and how competitions build confidence covers the part that matters more than any medal.

Frequently asked questions

Do we register directly or through school? School-registered olympiads go through the school. If your school does not participate, ask — many will register if a few parents request it.

Is there an entry fee? School olympiads usually charge a modest fee per subject. NTSE and the selection track have their own arrangements through the school or state.

Can a Class 5 child attempt the international selection track? No. That track starts around Class 8. Younger children should build foundations through school olympiads.

Does olympiad rank matter for school admission? Rarely in any formal sense. The real value is the skill and confidence built, not the certificate.

My child scored poorly in their first olympiad. Should they continue? Almost always yes. First attempts are about learning the format. Improvement between the first and second attempt is usually the largest jump a child makes.

Preparation that matches the paper

Our Maths Olympiad course covers Grades 3 to 8 — the syllabus questions, the reasoning section, and the number-theory ideas that school does not teach.
