The International Olympiad on Astronomy and Astrophysics is regulated by the Statutes, which all participants must agree to abide by. The Statutes may (and have been) modified by majority vote of the International Board, to respond to changing circumstances and to better serve the aims of the IOAA.

The current version of the statutes, which is binding for the 5th IOAA, is available for download below. All team leaders, and especially the leaders of new teams, are strongly encouraged to read them before attending the IOAA.
