The USA Biology Olympiad (USABO) is a national competition sponsored by the Center for Excellence in Education. Each year, twenty National Finalists gather at a nationally recognized institution for a two-week training camp. From the program's inception through 2009, the camp was held at George Mason University; as of 2010, the camp is instead held at Purdue University. At the end of the two weeks, four people are selected to represent America at the International Biology Olympiad.
USABO finalists are selected in two rounds of tests. The open exam is a short, multiple-choice exam open to all high school students. Competitors in roughly the top five percent move on to a semifinal exam. This second exam consists of another short multiple-choice section, followed by a short answer/matching section. The twenty highest scorers move on to the USABO finals. After the two-week training camp, the finalists undergo a day of practical examinations and a day of theoretical testing similar, in some respects, to the semifinal examination; however, the finals exam is far more comprehensive.
