International Olympiad on Astronomy and Astrophysics

The International Olympiad on Astronomy and Astrophysics (IOAA) is an annual astronomy and astrophysics competition for high school students, aimed to promote the growing interest in astronomy and related STEM subjects. It is one of the international science olympiads, and was founded from a dissidence inside the International Astronomy Olympiad, in order to increase the scope of the organization.

The IOAA consists of a theoretical exam, a data analysis exam, and an observational exam. A separate team competition is also included, where international teams are formed by randomly selecting members from different countries. The results of the team competition do not affect the individual results.
