The SOF Olympiad exam dates for 2026-27 have been announced for the International Mathematics Olympiad (IMO), International English Olympiad (IEO) and International Science Olympiad (ISO).
For students planning to participate this academic year, knowing the examination schedule early makes it easier to create a structured preparation plan, practise regularly and avoid last-minute pressure.
Science Olympiad Foundation provides multiple dates for each Olympiad. Participating schools can select one of the available dates according to their academic calendar. Students and parents should therefore confirm the final examination date with their respective school.
Students preparing for Maths, Science or English Olympiads can also explore VaaGa Academy's online Olympiad classes for Classes 2–8 for structured preparation, live learning and regular practice.
The SOF International English Olympiad (IEO) is designed to assess students' understanding and application of English language skills.
For the 2026-27 academic session, the three Level 1 examination dates are:
30 September 2026, 27 October 2026 and 17 November 2026.
A participating school may select any one of these dates. Students do not individually choose their examination date.
IEO preparation generally involves vocabulary, grammar, reading comprehension, sentence structure and the practical application of English.
Students should not limit their preparation to memorising grammar rules. Regular reading, vocabulary development and Olympiad-style question practice can help develop greater accuracy and confidence.
Younger learners beginning their preparation can explore VaaGa Academy's Class 2 English Olympiad program, while higher-grade students can use the same class-wise programme structure for focused preparation.
The SOF International Mathematics Olympiad (IMO) evaluates mathematical knowledge as well as logical reasoning and problem-solving ability.
SOF has announced the following Level 1 examination dates for the 2026-27 session:
23 October 2026, 26 November 2026 and 10 December 2026.
The participating school selects one of these dates to conduct the examination.
For Maths Olympiad preparation, students should focus on understanding concepts instead of relying only on formulas and memorised methods.
Regular preparation can include:
Students in Class 5, for example, can explore the Class 5 Maths Olympiad program for structured learning, personalised guidance and regular assessments.
The same principle applies to every grade: build the fundamentals first and gradually introduce more challenging Olympiad-level problems.
The SOF science competition is now known as the International Science Olympiad (ISO).
The Level 1 Science Olympiad exam dates for 2026-27 are:
30 October 2026, 19 November 2026 and 3 December 2026.
Schools can select any one of these dates for conducting the examination.
Science Olympiad preparation requires more than memorising definitions from textbooks. Students are often expected to understand scientific concepts and apply them to different situations.
Preparation should therefore include conceptual learning, observation, logical reasoning and regular practice with application-based questions.
Students starting at a younger age can explore VaaGa Academy's Class 2 Science Olympiad classes.
For older students, programmes such as the Class 5 Science Olympiad and Class 7 Science Olympiad can support class-specific preparation.
Students normally participate in SOF Olympiads through their schools.
According to the official 2026-27 schedule, schools may submit registrations up to 30 days before the examination date they select. Students cannot individually select a different exam date once their school has finalised its schedule.
However, parents should not wait until the official deadline.
Schools may have their own earlier deadline for collecting student details, consent and registration fees. It is therefore advisable to contact the school well in advance.
No. The participating school selects the examination date.
For example, SOF IMO is available on 23 October, 26 November and 10 December 2026. A school chooses one of these dates and students registered through that school appear for the examination accordingly.
SOF also states that separate question papers are used for different dates and a change of examination date is not permitted after selection.
Parents should confirm the exact date with their child's school before finalising the preparation schedule.
Yes.
SOF has stated that IMO, IEO and ISO will have Level 2 examinations for qualifying students from Classes 3 to 12 during the 2026-27 session.
The exact Level 2 examination date has not yet been announced. SOF currently indicates that it is expected to be held on the second or third Sunday of February 2027, with the final date expected to be announced by December 2026.
Students who qualify for Level 2 should therefore continue practising after their Level 1 examination rather than stopping their preparation entirely.
There is no single preparation schedule suitable for every child.
A student who already has strong concepts may require less preparation time than someone encountering Olympiad-style questions for the first time.
However, consistent preparation over several weeks is generally more effective than intensive last-minute study.
Students should concentrate on understanding the syllabus, strengthening weak concepts and becoming familiar with Olympiad-style questions.
This is a good stage to increase practice, solve more challenging questions and begin working within time limits.
Preparation can gradually shift towards mock tests, revision, time management and analysing mistakes.
VaaGa Academy's Olympiad programmes combine live interactive learning, personalised attention and regular assessments, helping students follow a more structured preparation process rather than relying entirely on last-minute practice.
Knowing mathematical formulas, grammar rules or scientific concepts is only one part of Olympiad preparation.
Students also need to know how to apply that knowledge under examination conditions.
Mock tests can help students learn to:
The objective should not simply be to complete more tests. Students should review their mistakes after every assessment and understand why an answer was incorrect.
For Maths preparation, students can combine mock-test practice with programmes such as VaaGa's Class 5 Maths Olympiad classes to strengthen both conceptual understanding and problem-solving ability.
For parents who want to save the important dates:
SOF IEO:
30 September 2026
27 October 2026
17 November 2026
SOF IMO:
23 October 2026
26 November 2026
10 December 2026
SOF International Science Olympiad (ISO):
30 October 2026
19 November 2026
3 December 2026
Students should remember that these are the dates provided by SOF, while the actual exam date applicable to an individual student depends on the date selected by their school.
SOF IMO Level 1 will be conducted on 23 October, 26 November and 10 December 2026. Participating schools select one of these dates.
The IEO Level 1 examination dates are 30 September, 27 October and 17 November 2026.
The SOF International Science Olympiad is scheduled for 30 October, 19 November and 3 December 2026.
The participating school selects one of the available examination dates provided by SOF.
SOF participation is generally processed through participating schools. Students should contact their school regarding registration and the selected examination date.
Yes. SOF has announced Level 2 examinations for qualifying students in Classes 3–12 for IEO, IMO and ISO. The examination is tentatively expected in February 2027.
Knowing the SOF Olympiad exam dates 2026-27 is the first step. The next step is creating a preparation plan that gives students enough time to understand concepts, practise Olympiad-style questions and improve through regular assessments.
VaaGa Academy provides online Olympiad preparation for Classes 2–8 across Maths, Science and English, with live interactive classes, experienced tutors, personalised guidance and structured practice.
Rather than waiting until the examination is close, students can begin steadily and build the confidence needed to approach Olympiad questions effectively.
