The Science Olympiad Foundation (SOF) is an educational foundation and a non-profit organisation based in New Delhi, India which promotes science, mathematics, introductory computer education and English language skills amongst school children in India.

It organizes six Olympiads annually, namely the National Cyber Olympiad (NCO), the National Science Olympiad (NSO), the International Mathematics Olympiad (IMO), the International English Olympiad (IEO), International General Knowledge Olympiad (IGKO) and the International Company Secretaries Olympiad(ICSO). In 2016, there was an olympiad, the International Sports Knowledge Olympiad (ISKO), but its place has been taken by IGKO.

The NCO, NSO and IMO are conducted in two levels. But the IEO, IGKO, NCO and ICSO are 1-level examinations. However, the website insists that IEO now also has an "international level." IEO was a single-level exam. From the year 2017–18, IEO has become a two-level exam.

Eligibility and Pattern

Students from class I to XII can participate. There is a different exam paper for each class. The question paper consists of 50 multiple choice questions, to be answered in one hour. Five questions that are part of the 'Achievers' section' carry 3 marks each whereas the remaining questions carry one mark each. Students are required to mark their answers on an OMR sheet. Results are announced for every student and it includes the student's overall rank, state rank, school rank, percentile score, etc. From among 200000 students that participate in each of these Olympiads every year, the top 500 students, top 10 students in each state, as well as school toppers from schools having a participation of more than 10 students in the exam, are selected for the second level. SOF also generates a performance report for all participating schools, as well as awards teachers and principals whose pupils excelled in the exam. Three school toppers who got more than 50% means 30 out of 60 or more than 30 marks get medals {gold, silver, bronze } and are selected for the second level of the examination.
