The International Junior Science Olympiad (IJSO) is an annual individual and team competition in the Natural Sciences for students who are under sixteen years old on 31st December of the competition year. IJSO has been established in recognition of the significance of the Natural Sciences in the general education of young people and in all aspects of their lives. It is a purely educational event.
The academic competitions of the IJSO include challenging tests in topics of science, both as theory questions and practical tasks. The tests are designed to address students' understanding of concepts, and their ability to apply concepts to the situations described in the tests.
