SOF Olympiad Exam Dates 2026-27
The table above is based on the official 1st Level Exams 2026-27 schedule published by SOF.
Important Note on SOF Exam Dates
SOF has clearly mentioned that a school can conduct an Olympiad on only one selected date from the official options. Since different dates have different question papers, students should check the final exam date with their school coordinator instead of assuming that all schools follow the same date.
SOF Eligibility Criteria 2026-27
The SOF eligibility criteria 2026-27 depend on the Olympiad selected by the student. The official SOF exam schedule clearly mentions the class range for each exam, and registrations are accepted through schools. SOF also states that students should confirm the exact exam date with their school because each Olympiad is conducted on 2 or 3 dates with different question papers.
Who Can Apply for SOF Olympiad Exams?
Students can apply for the SOF Olympiad exams according to their class eligibility for each subject exam. The official 2026-27 schedule shows the following class-wise eligibility:
SOF Level 1 and Level 2 Structure
SOF does not follow the same exam structure for every Olympiad. According to the official 2026-27 schedule, SOF IEO, SOF ISO, and SOF IMO will have a Level 2 exam for students of Classes 3 to 12. The same official note also confirms that SOF ISSO, SOF IGKO, SOF ICO, SOF IHO, and SOF ICSO are single-level exams.
Which Students are Eligible for SOF Level 2?
For the 2026-27 cycle, only students from Classes 3 to 12 can appear for Level 2 of SOF IEO, SOF ISO, and SOF IMO. Students of Classes 1 and 2 can still appear for these Olympiads at Level 1, but the official note limits Level 2 to Classes 3 to 12 only.
Single-Level SOF Exams
Some SOF Olympiads are conducted only once and do not have Level 2. The official SOF schedule lists ISSO, IGKO, ICO, IHO, and ICSO as single-level exams. In addition, the official ISSO FAQ page specifically states that SOF ISSO is a single-level exam and that students of Classes 3 to 10 are eligible, with no minimum marks criterion mentioned there.
Important Eligibility Note
The official student information page makes it clear that SOF registrations are accepted through schools, not through an open individual process on the main exam page. So, even if a student is eligible by class, the final participation happens through the school’s registration process.
SOF Registration Process and Exam Fee 2026-27
The SOF registration process is school-based. SOF’s online registration pages for 2026–27 clearly state that the form is for schools only, SOF does not accept individual participation, and students must register through their respective schools. The official exam schedule also says schools may send registrations 30 days before the chosen exam date.
How to Apply for SOF Exam
Students cannot apply directly on the SOF portal as individual candidates. The school completes the registration, forwards student details, and submits the payment to SOF through the official school registration system. SOF’s 2026–27 school registration pages and school registration form download page both repeat that the registration forms are meant for schools only.
Step-by-Step SOF Registration Process
Here is the cleanest way to explain the process on the page:
Check if your school is participating in SOF Olympiads.
Choose the Olympiad you want to appear for based on your class and subject.
Confirm the exam date selected by your school from the official SOF schedule.
Submit your details to the school before the registration deadline.
School sends the registration and payment to SOF through the official school registration system.
Can Students Register Individually for SOF Exam?
No. SOF’s official 2026–27 registration pages say that individual registrations are not accepted and that students may register through their schools only. Subject-specific SOF pages such as ICSO and ISO also repeat the same rule.
SOF Exam Fee 2026-27
For schools in India, Bhutan, and Nepal, SOF’s official registration fee is ₹170 per student per Olympiad, inclusive of GST. SOF also says schools may charge up to ₹30 extra per student towards honorarium for the in-charge, teacher support, and related expenses. Students with major physical disabilities and Indian students whose parent was martyred during defence operations are exempt from the registration fee.
SOF Fee for Students Outside India
For schools outside India, Bhutan, and Nepal, the official SOF registration fee is US$11 per student per Olympiad, and an additional US$1 per student may be charged for related expenses.
Is There Any Fee for a School to Become an SOF Exam Centre?
SOF’s participation pages for Olympiads such as IMO, IGKO, and ISO state that no fee is required from the institution to become a registered examination centre. Those pages also note that the school must register students through the official process.
SOF Exam Pattern 2026-27
The SOF exam pattern 2026-27 varies by Olympiad and by class, but the overall structure is quite consistent. On the official SOF pattern page, most Olympiads show 35 questions for 40 marks for lower classes and 50 questions for 60 marks for higher classes. The section names change by subject, but the paper usually includes a subject-focused section along with an Achievers Section.
SOF Exam Duration
SOF sample papers and syllabus pages show that the exam duration is 1 hour. This appears consistently across classes and major Olympiads in the official material.
SOF Exam Mode
SOF provides a sample OMR sheet for practice, and its official answer-key pages ask students to match the answers they marked on their OMR sheets. That means students should expect an OMR-based answer format in the exam.
General SOF Pattern Overview
This broad pattern is reflected in official SOF pages for exams such as IMO, ISO, and IEO.
SOF Exam Pattern for Major Olympiads
These section-wise details come directly from SOF’s official pattern and marking scheme pages.
SOF Pattern for Other Olympiads
The official SOF pattern page shows this same lower-class and higher-class split across the other Olympiads as well.
SOF Marking Scheme
The SOF marking scheme depends on the class and section. For lower classes, the Achievers Section usually carries 2 marks per question, while for higher classes it commonly carries 3 marks per question. The remaining sections are generally 1 mark per question. This structure is visible across official pattern pages and sample papers.
SOF Results, Answer Key, Awards and Rank Details
The SOF results are published on the official SOF results portal. SOF states that results are generally declared about 6 weeks after the completion of the last leg of the exam. The official student information page also says the results are emailed to schools, sent by SMS to students whose phone numbers are filled in on the OMR sheet, and uploaded on the SOF website.
How to Check SOF Results
Students can check their result through the official SOF result portal using their exam details. The official results page presents it as the place to view final SOF Olympiad results online. SOF also separately confirms that schools receive results by email and students may receive SMS updates if their mobile number is provided on the OMR sheet.
When Will SOF Results Be Declared?
The safest and most accurate way to write this section is:
SOF results are generally declared around 6 weeks after the completion of the last leg of the exam.
That exact timeline appears on the official SOF student information page.
SOF Answer Key
SOF publishes official answer keys and cut-off details on its website. The currently available official page is for 2025-26, where SOF says that answer keys for various Olympiads are shared so students can match the answers marked on their OMR sheets with the correct answers. For your page, it is best to avoid writing that the 2026-27 answer key is out unless SOF publishes that specific page later.
SOF Awards and Recognition
SOF provides awards, scholarships, medals, certificates, and recognitions based on school rank, zonal rank, and international rank. The official awards page says that for the Olympiads conducted during 2025-26, the total value of awards, scholarships, and felicitations was over ₹24 crores, and the same page explains the award structure for the 2026-27 exams.
Level 1 Awards
At Level 1, all participating students receive a Certificate of Participation and a Student Progress Report. The official awards page also says that Gold Medal of Distinction and Certificate of Distinction are awarded to the top 25 zonal rank holders per class per exam across the 26 zones. School-level Gold Medals of Excellence are also awarded based on the number of registrations in a class.
Final Level Awards for IEO, ISO and IMO
For SOF IEO, SOF ISO, and SOF IMO, the official awards page says that for Classes 3 to 12, the International and Zonal topper awards are based on Level 2. The same page lists the Top 5 International Awards for 2026-27 for these exams, with cash awards of ₹50,000, ₹25,000, ₹10,000, ₹7,500, and ₹5,000 for ranks 1 to 5 respectively.
Awards for Single-Level SOF Exams
For IGKO, ICSO, ICO, IHO, and ISSO, SOF says that all classes are considered for International and Zonal topper awards at Level 1, because these are single-level exams. SOF also states that class topper awards are provided at Level 1.
Student Progress Report
Each student is provided with a Student Progress Report (SPR). The official SOF FAQ explains that the SPR shows the student’s strong and weak areas and gives a performance comparison at school, city, zonal, and international level. It also includes an analysis of the student’s past-year performance.
SOF Rank Details and Tie-Breaking
SOF ranks students based on the marks obtained. The official ranking page shows the section-wise priority order used for different Olympiads and explains the 2nd-level ranking criteria. If students score the same total marks in Level 2, SOF determines rank using:
marks in higher-priority sections in Level 2,
total marks in Level 1,
and then marks in higher-priority sections in Level 1.
Additional SOF Scholarships
Apart from Olympiad rank-based awards, SOF also runs separate scholarship schemes. For 2026-27, the official site lists:
SOF Academic Excellence Scholarship (AES), where 260 winners are selected and each winner receives a trophy, ₹5,000 scholarship, and a citation.
SOF Girl Child Scholarship Scheme (GCSS), under which up to 300 girls from economically weaker sections can receive ₹5,000 each for one academic year.
