The WHO Family of International Classifications (WHO-FIC) Network was established in 1970 to promote the implementation, use, maintenance, and updating of the WHO reference classifications. It includes all designated WHO Collaborating Centres (as well as those under designation), such as the German Collaborating Centre. Since the ICF Research Branch is a partner within the German Collaborating Centre, it is considered a part of the WHO-FIC Network. The WHO-FIC Network is governed by an Advisory Council and supported by a small executive group. Since 1970, the WHO-FIC Network has established 4 committees and 3 reference groups.
