Competition Other


The "International Junior Science Olympiad" took place for the first time in 2004 in Jakarta, Indonesia. Since then, the 300 brightest minds in the natural sciences from 50 nations around the world have met every year in December to compete for gold, silver, and bronze, both individually and in teams. Since the competition was founded, more than 80 nations have participated in the IJSO by sending observers or teams of students. Currently, the IJSO has 48 Member States which regularly participate in the School Olympics.

The IJSO addresses pupils aged 15 and under. Across borders and cultures, the IJSO promotes the development of scientific competences and strengthens the international exchange of the next generation of young researchers at an early stage. Both theoretical knowledge in biology, chemistry, and physics, as well as skill in experimenting, are some of the demands. The IJSO is the youngest of the six science Olympiad organized by the IPN Leibniz Institute for the Education of Science and Mathematics. Every year, around 4,000 young people between the ages of 9 and 15 register for the four-stage task competition nationwide, which is funded by the Federal Ministry of Education and Research and the education authorities of the federal states.

Participation in the contest is free of charge. Costs for travel, accommodation, and meals for IJSO seminars are generally reimbursed within the framework of the guidelines of the BMBF.

Minimum Technical Skill Needed


In order to succeed in this selection competition, participants must have a comprehensive theoretical knowledge in biology, chemistry, and physics as well as skills for practical experiments.

Time Commitment

The amount of time dedicated to the competition tasks and projects (in addition to any possible preparatory work) is at the discretion of the participant. This is also subject to variability depending on the number of rounds that the entrant partakes in.

Application Deadline

The registration dates for the 2020 have closed. The pre-registration will start in January 2021 for the next contest.

Application Process Includes

Complete the tasks of the first round, register in the ScienceOlympiaden portal for the competition and submit your workouts to the date agreed with your subject teacher in Biology, Chemistry or Physics. Each of the parts of the tasks successfully processed receives a certificate of participation.

If you have been particularly successful in junior or mid-level science competitions in your state, you may be suggested to participate in the IJSO. You can then skip the task round and get started right away in the quiz round. You can not apply directly but must be proposed by the head of your school at your country representative.
