Founded in 2013, the USAAAO started as a group of six high school students who were interested in astronomy and astrophysics. They had heard about the Physics and Chemistry Olympiads that currently existed to foster students’ interest in the sciences. When they learned that there was an international-level astronomy Olympiad, and that more surprisingly, the US did not participate, they wanted to change that. They came into contact with each other via email, and collaborated to form the USAAAO.
That year, they took the initiative of forming a team to represent the USA at the 7th International Olympiad on Astronomy and Astrophysics. Receiving two individual honorable mentions and 11th place in the team competition, they returned and began preparation to establish a national selection procedure for future teams.
