At the National Model United Nations simulation conference, each participating college or university represents a member state of the United Nations or a nongovernmental organization (NGO). The students represent their country or NGO in simulated committees and organizations and develop resolutions and reports. The participants need to function as diplomats who can state their position and attempt to have it generally accepted while at the same time being open to compromise. The point is to safeguard the interest of the country or to represent the NGOs. The conference concludes with voting in the General Assembly or the Economic and Social Council on selected resolutions.

The National Model United Nations will be held in a Marriott Hotel in New York City. Some meetings will take place in the Headquarters of the United Nations. The conference language is English. Students from any department of Freie Universität are eligible to apply.

The project area Model UN/Model EU in the working division under Professor Philip Kunig of the Department of Law organizes Freie Universität's annual participation in the National Model United Nations. The preparation takes place during the winter semester in a weekly four-hour interdisciplinary workshop (Wed. + Thur., 4-6 p.m.).
