Earliest eligible DOB1 August 2007
Latest eligible DOB31 July 2014

Recognised boardsCBSE, ICSE, State Boards, IB, IGCSE, NIOS and other recognised systems may apply if every other criterion is met
Both class and DOB must match. Being in an eligible class does not override the date-of-birth rule, and being within the DOB range does not override the class rule.

Citizenship and location

Passport, OCI and residence conditions

Indian-passport eligibility

The official criteria state that the student must be eligible to hold an Indian passport. Students and parents should use the official document—not assumptions about nationality—as the deciding reference.

OCI provision

OCI card holders are provisionally eligible through earlier stages, subject to the stated conditions and any future legal or government revision. The 2026 document says OCI students are not eligible to represent India at IMO, EGMO or APMO.

Residence or Indian school system

The student must have been residing and studying in India since 30 October 2024 or earlier, or have been studying in an Indian school system since that date.

Students studying abroad in an Indian school system

An otherwise eligible student studying abroad in an Indian school system must come to India to write IOQM and later Indian stages if qualified. The student is treated as enrolled from Delhi-NCR for the relevant selection criteria and bears the travel cost. Read the official PDF for the full wording.

Official rule takes precedence

OCI and overseas-study provisions can change following court or government directions. Check the current official eligibility PDF immediately before relying on these provisions.

Education status

Class XII and university restrictions

Class XII board timing

The student must not have qualified—or be scheduled to appear for—the Class XII board examination earlier than 30 October 2026. The official criteria expressly prohibit forfeiting a Class XII result to try to meet eligibility.

University start

The student must not have commenced, or be planning to commence, study at a university or equivalent institution by 1 June 2027.

INMO 2026 awardees

The official document gives eligible INMO 2026 awardees a direct route to INMO 2027 without qualifying again through IOQM 2026 and RMO 2026, provided the stated age, university and later-stage eligibility conditions are satisfied. This is a special pathway; the full official clause should be read before acting on it.

Boards and schooling

Home-schooling, open schooling and recognised boards

The official IOQM portal says students following home-schooling or open-schooling may appear if they satisfy every eligibility condition and submit appropriate supporting documents. It also lists students from CBSE, ICSE, State Boards, IB, IGCSE, NIOS and other recognised systems as eligible subject to the complete criteria.

A board name alone does not establish eligibility. Class, DOB, passport eligibility, residence or school-system history, Class XII status and university plans must all be checked.

Prepare evidence

Documents used to support eligibility

During individual enrollment, the official instructions required a recent photograph, proof of current school and proof of date of birth. Registration for the 2026 cycle is now closed, but registered students should keep these files and their original records available in case verification is requested.

Photograph

A recent JPG or PNG photograph, following the official size and recency requirements.

Current-school proof

School ID, school-stamped fee receipt, previous report card or another permitted document for home-schooling cases.

Date-of-birth proof

Aadhaar, birth certificate, passport or another document listed in the current official upload instructions.

Names and DOB should be consistent across the application and supporting documents. If the registration record contains an error, use the official portal or helpdesk rather than creating a second registration.

Before relying on eligibility

Seven-point self-check for families

  1. The student is in Class 8, 9, 10, 11 or 12.
  2. The DOB is from 1 August 2007 through 31 July 2014.
  3. The Indian-passport or provisional OCI condition is understood.
  4. The residence or Indian-school-system condition has been met since 30 October 2024.
  5. The Class XII board examination is not qualified or scheduled before 30 October 2026.
  6. University or equivalent study is not planned to begin by 1 June 2027.
  7. Supporting records are accurate and available.

Eligibility remains the student’s responsibility. The official document states that a student found ineligible at a later stage may be disqualified.

Current cycle

Registration status does not change eligibility rules

New IOQM 2026 enrollment closed after 27 July 2026. Eligibility explains who could enroll; it does not reopen the registration window. Students already enrolled should keep their confirmation and monitor the official portal for payment, correction, hall-ticket and examination notices.
