Steering Committee
The IBO Steering Committee is the executive board of the international IBO Association. It manages the daily affairs of the association and represents the IBO legally. It also oversees the operations of the yearly IBO Competition, enacts its rules and guidelines and aides the host in their preparations. The Steering Committee members illustrate the diversity of this worldwide competition.
