A president controls the flow of the debate to encourage the active participation from delegates. Presidents must know the chairing procedures as they are the leaders of their committee. They are required to write two chair reports, while assigning the remaining two chair reports to each deputy president.
A deputy president assists the president in running the forum. There are two deputy presidents for each committee, and they are expected to be familiar with the chairing procedures to chair during the MUN conference. They also need to write one chair report on a topic assigned by their president.
