The Olympiad was founded from a dissidence inside the International Astronomy Olympiad, in order to increase the scope of the organization.

The subsequent annual meetings were held in Indonesia (2008), Iran (2009), China (2010), Poland (2011), Brazil (2012), Greece (2013), Romania (2014), Indonesia (2015), India (2016), Thailand (2017) and China (2018).[2] The 13th IOAA was held in Keszthely & Heviz, Hungary.[3]
