Successful simulations of United Nations meetings, whether at the local, national or international level, require a great deal of preparation.
The United Nations Office on Drugs and Crime website offers resources that can be accessed prior to and during a Model United Nations conference.
These resources are valuable for the organizers of these conferences and are especially useful when preparing study guides and reviewing position papers. They are also relevant for delegates representing the different Member States and for the teachers who are responsible for training the Model United Nations delegates.
The United Nations offers a variety of other sources, such as UN4MUN, developed by the Department of Public Information.
UN4MUN provides guidance on simulating the Security Council and the General Assembly. In the case of the General Assembly, it provides rules of procedure similar to those used in actual meetings, with a focus on consensus.
