How to Apply for Maths Olympiad: Registration Steps for Classes 1 to 12

To apply for the maths olympiad, you usually register through your child’s school. The school coordinator hands out the registration form, collects the fee, and submits the entry to the exam body.

You cannot apply directly as an individual to the International Mathematical Olympiad (IMO), as participation is strictly by invitation for national teams selected through your country’s official mathematical organization.

The route is the same whether the student is in Class 1 or Class 12, and the main school based exams in India, the SOF International Mathematics Olympiad (IMO) and the SilverZone International Olympiad of Mathematics (iOM), both accept Classes 1 to 12.-

This guide covers how to apply for maths olympiad, who can apply at each stage, the step-by-the step registration process, fees, the current 2026-27 dates, and a sample letter you can send if your school is not a registered centre yet.

Which Maths Olympiads Accept Your Class

Entry is set by the class the student is currently enrolled in. These are the main options across the school years, with how each one takes applications.

Olympiad	Classes eligible	How to apply	2026-27 timing
SOF IMO	Classes 1 to 12, school registered with SOF	School only, no individual entry	Level 1 on 23 October, 26 November or 10 December 2026, Level 2 in February 2027 for Classes 3 to 12
SilverZone iOM	Classes 1 to 12	Normally through the school, using the SilverZone prospectus	Remaining dates 18 November and 7 December 2026
Math Kangaroo (USA)	Grades 1 to 12, kindergarten may sit the Grade 1 paper	Parent registers the student online	Contest on 18 March 2027
MOEMS	Grades 4 to 8, through a registered team	School or club coach registers the team	Five contests across the school year
MATHCOUNTS	Grades 6 to 8	School or chapter coordinator	Chapter round in February
AMC 8, 10, 12	AMC 8 up to Grade 8, AMC 10 up to Grade 10, AMC 12 up to Grade 12	Through a registered test centre or school	AMC 8 in January, AMC 10 and 12 in November
IOQM	Classes 8 to 12, the entry point to RMO and INMO	Student or school registers on the official portal	Exam in the autumn window
SilverZone Little Star	Nursery, LKG and UKG	Through the school	Announced per session

One correction worth making before you search further. The International Mathematical Olympiad that selects national teams is not an exam you apply for directly. In India the pathway runs through IOQM, then RMO and INMO, and only the top performers reach the training camp.

When most parents search for the maths olympiad, the exam they actually want is SOF IMO, SilverZone iOM or Math Kangaroo. The IMO exam eligibility criteria for Classes 1 to 12 page has the full class wise breakdown.

Maths Olympiad Age Limit and Class Eligibility

There is no fixed maths olympiad age limit. Eligibility is set by the class the student is enrolled in, not by date of birth, so a Class 1 entrant is usually 5 to 7 years old and a Class 12 entrant is usually 16 to 18.

The rules that do apply across every grade:

• Class based entry: a student sits the paper for the class they are currently studying in.
• No level skipping down: a student cannot register for a level below their actual grade, though sitting a higher level is allowed in some Kangaroo regions.
• Kindergarten entry: Math Kangaroo allows a kindergarten child to take the Grade 1 paper if the child can read and work independently.
• Second level cut off: SOF IMO has no Level 2 for Classes 1 and 2, so the second stage starts from Class 3.
• Upper age rules: the senior pathway exams such as IOQM and INMO apply age and class limits tied to school leaving year, since they feed a national team.
• School enrolment: SOF and SilverZone both require the student to be enrolled in a recognised school.

So an olympiad for a 6 year old is normal, and a maths olympiad for a 5 year old is possible through kindergarten entry at Grade 1 level or through SilverZone’s Little Star Olympiad for Nursery, LKG and UKG.

How to Apply for Maths Olympiad Step by Step

The school route is the same for SOF IMO and SilverZone iOM at every class level. Work through these steps in order, and start at least four to six weeks before the exam date you are aiming for.

Step 1: Confirm Which Olympiad Your School Conducts

Ask the class teacher or the olympiad coordinator which exams the school runs this session and on which date. Schools pick one date from the options the exam body offers, so the exam day depends on the school’s choice, not yours.

Step 2: Collect the Registration Form

Registered schools receive the prospectus and the student registration sheet directly from SOF or SilverZone. The coordinator distributes the forms, usually with an internal deadline that falls well before the official one.

Step 3: Fill In the Student Details

Enter the name, class, section and date of birth exactly as they appear in school records. Name and class errors are the most common reason an admit card or a certificate comes back wrong, and corrections after submission are slow.

Step 4: Pay the Registration Fee

Fees are paid to the school coordinator, not to the exam body. SOF lists a fee of around 170 rupees per student per olympiad for Indian schools in the 2026-27 session, and SilverZone iOM has been in a similar range. Confirm the exact amount with your school before paying, since the figure is revised between sessions.

Step 5: Wait for Confirmation and the Admit Card

The school compiles all entries and submits them together. Once the exam body processes the batch, roll numbers and admit cards come back to the school, which passes them to students. Ask the coordinator for a rough date so you are not chasing it the week of the exam.

Step 6: If the School Is Not Registered, Ask It to Register

Any school can become a registered examination centre, and there is no fee for the school to register itself. SOF asks for a minimum group of students from a school, and SilverZone mentions a similar minimum for the Mathematics Olympiad, so the coordinator usually needs a handful of interested families before going ahead. The sample letter below makes that request easy to send.

How to Register Without Going Through School

Several competitions accept entries straight from a parent or an older student, which is the way around an unregistered school.

• Math Kangaroo: open to Grades 1 to 12. Registration opened on 15 September 2026 for the 2027 contest, at 20 US dollars per student until 31 December 2026 and 35 US dollars from 1 January to 1 February 2027. The contest runs on 18 March 2027.
• AMC 8, 10 and 12: students sit the paper at a registered school or test centre, so find a centre that accepts outside candidates and register through it. See AMC registration for the current process.
• IOQM: senior students can register on the official portal without school sponsorship, which makes it the usual entry point for Classes 8 to 12.

For the Kangaroo route, pick the centre first, then complete the student details and pay. Our guide on Math Kangaroo registration walks through the form screen by screen, and the Math Kangaroo levels page shows what each grade’s paper looks like.

Sample Letter to Ask Your School to Register for the Maths Olympiad

Many parents need two things in writing: a request asking the school to register as an olympiad centre, and permission for the student to attend on exam day. Use this template for either, and change the exam name, class and date to match.

Subject: Request to register our class for the Maths Olympiad

Respected Principal,

I am the parent of [student’s name], a student of Class [X], Section [Y]. I would like to request that the school register as an examination centre for the [SOF IMO / SilverZone iOM] for the current session, so that interested students can participate.

I understand there is no fee for the school to register as a centre and that the exam is conducted within school premises. [Number] other parents have expressed interest. My child has my permission to attend the examination on the scheduled date and to be absent from regular classes for that period if required.

Please let me know the form, fee and deadline so that I can complete the formalities on time.

Thank you,
[Your name], [contact number], [date]

If the school is already registered and you only need permission to attend, keep the first paragraph and the permission line, and drop the request to register as a centre.

Key Dates for the 2026-27 Olympiad Season

Deadlines run roughly 30 days ahead of each exam date, and schools set their own internal cut off before that. These are the dates to work backwards from.

Exam	Exam date	Approximate registration cut off
SOF IMO Level 1, date 2	26 November 2026	Late October 2026
SOF IMO Level 1, date 3	10 December 2026	Early November 2026
SOF IMO Level 2, Classes 3 to 12	February 2027	No separate entry, qualification is automatic
SilverZone iOM, date 2	18 November 2026	19 October 2026
SilverZone iOM, date 3	7 December 2026	7 November 2026
Math Kangaroo 2027	18 March 2027	31 December 2026 for the regular fee

Level 2 needs no fresh application. The class wise top 5 percent from Level 1 are called forward automatically, and the SOF IMO Level 2 guide explains how that selection works.

What Each Class Is Tested On

The paper tracks the school syllabus for the class, with an extra reasoning section that school exams usually skip. The weighting shifts as the student moves up.

• Classes 1 to 3: counting and number sense, addition and subtraction, basic shapes, measurement, patterns and odd one out reasoning.
• Classes 4 to 5: fractions, factors and multiples, long division, area and perimeter, and multi step word problems.
• Classes 6 to 8: integers, ratio and proportion, algebraic expressions, geometry proofs at an introductory level, and data handling.
• Classes 9 to 10: polynomials, coordinate geometry, trigonometry, circles, surface area and volume, and probability.
• Classes 11 to 12: functions, sequences and series, permutations and combinations, calculus basics, and number theory in the senior pathway exams.

The IMO syllabus for Class 1 and the wider SOF IMO syllabus list topics section by section, and the SOF IMO exam pattern shows the marks split for each part at each level.

How to Prepare After You Apply

Preparation works best in short regular sessions rather than long weekend drills, at any age. Fifteen minutes a day for six weeks beats three hours the Sunday before.

• Start with the official sample paper: the SOF IMO sample paper shows the question style before the topics get harder.
• Practise daily on the app: the Gonit app has olympiad style practice across Grades 1 to 12, with step by step solutions. See best apps for SOF IMO preparation for how it compares to other options.
• Fix the fundamentals first: younger students should work through addition and subtraction for Class 1 or place value, while middle school students usually need long division and equivalent fractions solid before reasoning questions.
• Build problem solving separately: reasoning questions reward pattern spotting, so use the ideas in how to solve math olympiad problems and how to improve problem solving skills for IMO.
• Do one timed practice: a single full length mock in the final week teaches pacing without creating exam anxiety.

If you are still deciding between exam bodies, the SOF vs SilverZone comparison covers difficulty, awards and cost, and SOF IMO vs IOQM explains which one matters for a senior student aiming at the national pathway.

Common Mistakes When Applying

Most failed applications are admin problems, not ability problems. These are the ones that come up every session.

• Missing the school’s internal deadline: it is often two to three weeks ahead of the official one.
• Assuming direct registration is possible: SOF does not accept individual entries, so a parent cannot bypass an unregistered school.
• Registering for the wrong class: the paper is tied to the class the student is currently in.
• Waiting for the school to announce it: many coordinators only circulate forms if parents ask first.
• Applying for a level the student has outgrown: AMC 10 and AMC 12 have class and age ceilings, so check before paying.
• Treating the fee as the last step: the entry is not confirmed until the school submits the batch to the exam body.

FAQs

Conclusion

Applying for a maths olympiad is mostly an administrative job, and the students who miss out usually miss a deadline rather than a question. Decide which exam fits the class and the goal first. If the school already conducts SOF IMO or SilverZone iOM, speak to the coordinator and get the form this week. If it does not, send the request letter above, and register for Math Kangaroo or an AMC centre directly as a backup so the student still gets a competition this season.

Once the entry is confirmed, treat preparation as a daily habit rather than a project. Short sessions on sample questions, a weekly look at a reasoning topic, and one timed mock before the exam is enough at any grade. The result matters far less than the fact that the student sat a real paper and found parts of it interesting.
