USA Biology Olympiad (USABO)

Email CEE Icon

As the premiere biology competition for high school students in the United States since it began in 2002, 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, 20 Finalists are invited to a residential training program at the USABO National Finals, soon to be held at the University of California San Diego and most recently hosted by Marymount University. The students participate in 10 days of biology instruction inclusive of laboratory training and conceptual understanding followed by two days of testing. Ultimately, four students earn the right to advance as Team USA at the International Biology Olympiad (IBO), a worldwide competition involving student teams from over sixty countries.

Since CEE began administering the USABO, every member of "Team USA" has medaled at the IBO. All four members of the Team USA in years 2004, 2007, 2008, 2009, 2011, 2012, 2013, 2015, and 2017 were awarded gold medals. Individual Team USA members achieved the coveted Number 1 student position in the world in 2011 and 2013. Team USA has achieved the world No. 1 ranking in 2011, 2013, 2015, and 2017. In 2017, Team USA attained four gold medals at the IBO at Warwick University in Coventry, United Kingdom.
