As one of the International Science Olympiads under the United Nations Educational, Scientific and Cultural Organization, the IOI aims at promoting coding education and nurturing students’ computational thinking and problem-solving skills.

Since 1997, the EDB and the Hong Kong Association for Computer Education have jointly organised the Hong Kong Olympiad in Informatics (HKOI). Outstanding winners from HKOI are selected as Hong Kong representatives every year to enter the IOI. They are required to attend a series of training programmes to better prepare for the international competition. As a tradition of passing the torch, many of the trainers are previous contestants of the IOI.
