The International Biology Olympiad (IBO) is the world’s leading biology competition for high school students, held each year in a different host country. The inaugural event took place in 1989 in former Czechoslovakia (now Czech Republic), with participants from six nations. Since then, the IBO has grown significantly, now involving 78 countries across five continents. Participants are assessed on their ability to solve complex biological problems and perform practical laboratory tasks. A strong passion for biology, along with creativity, innovation, and determination, is essential.
