Ad hoc Groups

An ad hoc Group is convened at the initiative of the Director General to provide expert advice on a topic as defined by the Terms of Reference. The ad hoc Group reports are considered by the relevant Specialist Commission or Director General. An ad hoc Group usually comprises six internationally recognised experts and take into consideration geographical representation and gender balance.

Nomination of experts

Delegates may nominate experts for specific ad hoc Groups, in particular for those that are in the planning phase not yet formally established. Delegates are also invited to consult the Commission’s work plan to identify potential upcoming area of work. Delegates may send the name(s) of the expert(s) via email to [email protected]. However, experts must submit their relevant information by filling out this form. This information will be considered but does not guarantee that the expert will be selected. It will assist WOAH in establishing a database of internationally recognised experts.


Ad hoc Group reports

Ad hoc Group reports published since 2016 can be accessed from the menu on the top of this page. To access reports prior to July 2016, please refer to reports of the relevant WOAH Specialist Commission available here.
