Model United Nations (also Model UN or MUN) is similar to the United Nations in which students participate as delegates to various UN Committees. Participants research and formulate political positions based on the actual policies of the countries they represent. The committees usually consist of the six committees of the General Assembly. The participants range from middle school students to graduate school students. Model United Nations involves researching, public speaking, debating, and writing, often along with critical thinking, teamwork, and leadership skills.

Perhaps the most important aspect of Model UN is to help students gain a knowledge of international affairs and promote international peace and cooperation amid a time of political turmoil in certain regions of the world:

"If the United Nations once admits that international disputes can be settled by using force, then we will have destroyed the foundation of the organization and our best hope of establishing a world order."

-Dwight D. Eisenhower
