Founded in 1995, the British Informatics Olympiad (BIO) aims to encourage students to take an active interest in information technology, and to allow them to meet and exchange ideas, through a challenging competition in computer programming.

The BIO information pack gives a quick link to find out more about the BIO. Many other countries run competitions like the BIO, including the All Ireland Programming Olympiad (AIPO) for students in Northern Ireland and the Irish Republic.
