About the International Biology Olympiad: Cultivating Global Excellence in the Life Sciences

The International Biology Olympiad (IBO) is the premier global competition for pre-university students passionate about biology. Established in 1990 in Czechoslovakia, the IBO has grown to include over 75 participating countries across five continents, making it one of the most prestigious science competitions worldwide.

The IBO is organized by the International Biology Olympiad e.V., a nonprofit association registered in Germany. This organization coordinates the annual event, which is hosted by a different member country each year. The event comprises rigorous theoretical and practical exams designed to challenge and inspire the most gifted biology students.

The IBO’s mission is to identify, inspire, empower, and support the next generation of leaders in the life sciences. It aims to foster international cooperation, promote excellence in biological education, and encourage intercultural dialogue among young scientists.

Since its inception, the IBO has been instrumental in shaping the careers of many young biologists, providing them with a platform to showcase their talents and connect with peers and mentors from around the world.
