Model United Nations, also known as Model UN or MUN, is an extra-curricular activity in which students typically role-play delegates at the United Nations and simulate UN committees.
MUN involves and teaches researching, public speaking, debating, and writing skills, in addition to developing the participant’s critical thinking, teamwork, and leadership abilities. The delegates of such conferences are placed in various committees found at the real UN and they are assigned countries (or in special situations or committees – political figures or other organizations), where they are supposed to represent members of that body.
Before an MUN conference, delegates are expected to conduct research on the subjects that are meant to be touched upon and formulate a position in alignment with their assigned country’s external and internal policies. Then, they are expected to debate with fellow delegates in order to find solutions to the problems that they are faced with, in real time.

Delegates are expected to work within formal and informal types of debating to come to a collective conclusion at the end of the conference, and write a resolution that shall be presented in the General Assembly. Resolutions are the basis of all debate. They are considered the final results of conversations, writings, and negotiations. Resolutions must go through a draft, approval by the chairs, and consequent debate and modification.

As for the dress code, nearly all Model UN conferences require delegates to wear Western business attire (WBA), as dressing professionally is an important way to show respect for the nation, organization, or individual one is representing, as well as for the rest of one’s committee.
