The International Science Olympiad


This is an annual science competition for secondary school students across the globe. It has been on for decades. The aim of the ISO are to promote a career in science from around the world and to compare the various teaching systems of each country. Over 100 countries in the world participate in this interesting science competition. Another interesting thing about ISO is that, you get to compete with your peer from different races in the world, you interact with people of different cultures and tribes and make new friends, exciting isn’t it?

In several countries, achieving a high ranking in any ISO guarantees access to a university of your choice. Nigeria and other African country participate in this big competition event as well.

There are 13 International Science Olympiads to date. They include

The International Mathematical Olympiad

The International Physics Olympiad

The International Chemistry Olympiad

The International Olympiad in Informatics

The International Biology Olympiad

The International Philosophy Olympiad

The International Astronomy Olympiad

The International Geography Olympiad

The International Linguistics Olympiad

The International Junior Science Olympiad

The International Olympiad on Astronomy and Astrophysics

The International Earth Science Olympiad

To participate in any of these International Olympiads, you would have to qualify in your country (National level). The body responsible for organizing the National Olympiads in Nigeria is the National Mathematics Centres (NMC). The NMC selects 4 – 5 successful students across the 36 states in Nigeria for each category and sponsor them to the competition.

Nigeria presently participate in 5 categories of the International Science Olympiad. These categories include

The International Mathematics Olympiad

The International Physics Olympiad

The International Chemistry Olympiad

The International Biology Olympiad and

The International Olympiad in Informatics.
