IBO is an association of national biology competitions from countries and regions.
IBO members are either countries or regions. We have grown from just 6 countries in 1990 to currently 75 members.
A Delegation of a country or region consists of 1-4 competitors (students) selected by their National Biology Olympiad and at least two Members of the jury.
Registration of a country must be made by the Country Coordinator. To check who are the Country Coordinator please check:
