About the IEO exam
How the exam works
Mode: Offline, objective multiple-choice paper held in school during school hours; each exam date has its own paper. · Levels: Level 1: Classes 1-12, held in the student's own school. Level 2: Classes 3-12 only; qualifiers are the class-wise top 5% internationally, the top 25 per zone per class, and school class toppers (where at least 10 students of that class sat the exam and the topper scored at least 50%). Level 1 questions are about 60% from the current class syllabus and 40% from the previous class; the Achievers Section and all of Level 2 use the current class syllabus only. · Duration: 60 minutes · Questions: Level 1: Classes 1-4 have 35 questions (Word and Structure Knowledge 15, Reading 10, Spoken and Written Expression 5, Achievers 5). Classes 5-12 have 50 (Word and Structure Knowledge 30, Reading 10, Spoken and Written Expression 5, Achievers 5). Level 2: Classes 3-4 have Word and Structure Knowledge 20 + Reading 10 + Achievers 5; Classes 5-12 have Word and Structure Knowledge 35 + Reading 10 + Achievers 5. · Marking: 1 mark per question except the Achievers Section: 2 marks each for Classes 1-4 (40 marks in total) and 3 marks each for Classes 5-12 (60 marks in total). SOF's published pattern does not mention negative marking. · Language: English
How to register
Only through the child's school: the school registers with SOF and sends the student forms, usually at least 30 days before its chosen exam date. Individual registrations are not accepted. Fee: Rs 170 per student per Olympiad incl. GST (India, Bhutan, Nepal), and schools may collect up to Rs 30 extra; US$11 elsewhere.
When it happens
Next Level 1 school dates: 17 November 2026. Earlier dates (30 September and 27 October 2026) have passed. Each school chooses one date; a future exam date does not mean registration is still open. SOF asks schools to submit registrations at least 30 days before their selected date. Level 2 is for qualifying Classes 3–12 only; SOF plans to announce the exact date by December 2026 and provisionally indicates the second or third Sunday of February 2027. This is tentative, not a confirmed exam date. Results are normally available within about 8 weeks. Status checked 1 November 2026; times are IST.
