| <p>The International Olympiad on Astronomy and Astrophysics (IOAA) strives to provide an inclusive atmosphere that encourages the free expression and exchange of scientific ideas. The IOAA is committed to prevent any unpleasant incidents that may occur during the events of the Olympiad itself, at International Board Meetings (IBM), during IOAA related discussions, and in general in any activity of its scientific bodies in which the IOAA has or shares responsibility. This includes any social activities and informal gatherings attached to the above mentioned events. </p>
