IJSO is one of the 12 most prestigious scientific olympiads in the world recognized by UNESCO. Here, students show how well they understand three natural sciences: physics, chemistry, and biology. They show their skills and knowledge in team and individual competitions.
Therefore, if you love explosive chemical experiments, understand how the theory of evolution works and why the jokes about Schrödinger's cat are funny, IJSO is waiting for you!

To prove your knowledge of natural sciences at the international level! You will take part in team and individual competitions to compete for prizes with contestants from all over the world.
You will also meet inspired like-minded people and join the international scientific community.
The olympiad has been held since 2004. In 2022, IJSO will be held in Ukraine for the first time. So, get ready to be creative and compete for the championship together with participants from all over the world and also show them Kyiv landscapes with the Dnipro river view and local historical sights.

Anyone under the age of 15 as of December 31 of the competition year can take part in the olympiad. In other words, children born after January 1, 2007 can become participants of IJSO 2022.
You have to pass the All-Ukrainian national selection to participate. According to the results, the jury forms a team of 6 participants who will represent Ukraine at the international stage.

There are the following stages including the international IJSO.

To participate in the first stage of the national selection, fill in the registration form. Later, you will receive an email with a unique link to the online test and instructions on how to complete it. Important: you can only take the test once from a single device!

Then, you will take part in the boot camp. Here, you will listen to lectures on Chemistry, Biology, and Physics. You will also work on tests and problems and conduct experimental research individually and in a team. In short, you will prove yourself and find out if you are in the team of finalists who will represent Ukraine at the IJSO international stage.

All IJSO members receive certificates for participation.
Winners get medals: gold (approximately 10% of participants), silver (20%), and bronze (30%) ones.
Teams (up to 3 people) can compete for a gold, silver, or bronze medal.
The total winner with the highest overall score will receive a special prize.
Also, the special prize will be awarded to the participant who has the highest number of points for the theory part (tests + theory).
The country whose team received the highest number of points will receive the "Country winner" award.

Ukrainian teams prove that it's possible!
In 2019, when Ukraine first presented its team at the IJSO international stage, our students returned with 3 bronze medals. This is a great result for the first time.
