The International Biology Olympiad (IBO) is an annual global competition designed for high school students who excel in biology. Participants are selected based on their performance in their respective National Biology Olympiads, with each country typically sending four students and two team leaders to represent their delegation.

The competition evaluates participants' theoretical knowledge and practical skills across a wide range of biological disciplines. Tasks include problem-solving, experimental design, and hands-on biological experiments. The goal is to challenge and inspire young biologists while fostering international collaboration and cultural exchange among students from over 70 countries.

The IBO promotes excellence in biological sciences and encourages students to pursue careers in science. The competition also serves as a platform to unite young talents in a spirit of friendship and academic growth​.
