The International Olympics on Astronomy and Astrophysics (IOAA) are one of 12 International Science Olympiads. Founded by five countries (Thailand, Indonesia, Iran, China, Poland), this first edition was held in Thailand in 2007.
The main goal of the IOAA is to promote a growing interest in astronomy and related STEM subjects, particularly through general education for young people, and to enhance the development of international contacts across different countries in promoting astronomy and astrophysics in schools. Through events like IOAA, brighter high school students are expected to become keen to study astronomy at the university level and become the next generation of astronomy and astrophysics experts.
