Many conferences simulate other IGOs including:
European Union
African Union
Organization of American States
The North Atlantic Treaty Organization or NATO
Arab League
Organisation of Islamic Cooperation
South Asian Association For Regional Co-Operation
Association of South East Asian Nations
International Atomic Energy AgencyA Model United Nations inTashkent, Uzbekistan
In addition, solely national organizations such as the United States National Security Council are often role played, with delegates role-playing specific people (e.g. the Secretary of State or the Secretary of Defense) rather than representing countries. This may be taken one step further, having the delegate represent merely the interests of his or her office, or role-play a specific holder of the office (e.g.Hillary Clinton). Such committees are typically "crisis committees;" that is to say, they do not begin with a fixed topic but rather are forced to deal with issues as they come up. A team of conference organizers (known as a crisis staff) develops a simulated event which acts as a catalyst for a crisis. The staff continually inform the committees of changing events on the ground, to which the committee must respond; in addition, individual delegates are typically allowed to take certain actions on their own, without committee approval, subject to the interpretation and agreement of the crisis staff. However, the correspondence between single-country and crisis committees are not perfect; for instance, the UN Security Council and some NATO bodies are typically run as crisis committees, and some national cabinets are fixed-topic committees.

Position papers
A position paper (sometimes known as a Policy Statement) is an essay that is written by participants of some models. It describes the detailed position of a certain country on a topic or issue that the writer will debate in his or her committee. Position papers are not always required, but certain conferences mandate that each delegate send his own before the opening. It is also known as the (Foreign) Policy Statement or (F)PS.[6]Format
Conferences have different format and styles for position papers. Nevertheless, UNA-USA established a format that has been adopted widely throughout the Model UN community. However, in Latin America the alternative TINK format, developed by of Argentina, is used. in Either way, most position papers consist of a heading with committee, topic, country and delegate information and body which explains in detail the position of the author's country. The position paper usually includes several pages outlining:
Background of the Topic
UN Involvement
Country's Positions
Possible Solution[edit]Purpose
Position papers should explain an issue from their country's point of view. It is also good practice that they include statistics about the issue that would support the cause they defend. The paper would also try to convince the other countries of the committee to their view of the issue. It would have ways to solve the situation.[7]
Many conferences require delegates to submit a copy of their position paper, as a means to ensure that the delegates research important topics and construct strong and well-informed positions on those subjects, yet presentation is still a valuable component.
