Organized and run directly by the Department of General Culture of the United Nations through the national Collegiate Conference Association (NCCA inc.), the NMUN is undoubtedly the greatest simulation of multilateral diplomatic process in the world.

Founded in 1923, at the same time of the creation of the League of Nations, which later in 1946 became the United Nations, the National Model United Nations each year witnesses the gathering together of more than 3,000 students from every corner of the planet at the Headquarters of the United Nations in New York.
The New York model is extremely educational from both a didactic and personal experience point of view.
The model is structured in several parts:

The "Opening Ceremony" which takes place in the Hall of the UN General Assembly during which the delegates attending the Conference are received. The "Guest Speaker Programme", during which each commission meets the world international diplomacy representatives in order to discuss topics related to the subjects included on the Commission agenda. The "Mission Briefing" is the meeting with the diplomatic delegation of the country represented at the concerning office of the UN permanent mission. The "Plenary Session", during which there is a presentation and formal voting of the resolutions and reports in the General Assembly and ECOSOC premises at the UN. The "Closing Ceremony" is the official closing followed by an awards ceremony.
