As the premiere biology competition for high school students in the United States, the USA Biology Olympiad (USABO) enriches the life sciences 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 Purdue University. Ultimately, four students earn the right to represent the USA at the International Biology Olympiad (IBO), a worldwide competition involving student teams from roughly sixty countries.

Since CEE began administering the USABO, every member of "Team USA" has medaled at the IBO. All four members of the teams from 2004, 2007, 2008, 2009, 2011, and 2012 were awarded gold medals. In 2011, Team USA achieved the coveted Number 1 position in the world—a first for the USABO.

2013 School and Student Registrations are now closed.
