USA Biology Olympiad

As the premiere biology competition for high school students in the United States, the USA Biology Olympiad (USABO) enriches the life science education of nearly 10,000 talented students annually. It provides the motivation, curricular resources, and skills training to take them beyond their classroom experience to the level of international competitiveness.

After two rounds of challenging exams, twenty Finalists are invited to a residential training program where they learn advanced biological concepts and exacting lab skills at the USABO National Finals. Ultimately, four students earn the right as Team USA to represent the USA at the International Biology Olympiad (IBO), a worldwide competition involving student teams from over sixty countries.
