Y-MUN is divided into several committees that vary in size and topic area. Student participants who are elected in advance lead each committee as Officers. Students in each committee are required to complete certain documents in order to best prepare for the conference.

The committees are:

General Assembly (GA)

The GA is the largest committee, in which students are expected to discuss and adopt resolutions dealing with a variety of international issues. These students also serve as the nation’s ambassador and represent the country at all formal hearings and events. In some cases, resolutions adopted by the General Assembly Subcommittees may be heard by the General Assembly and vice versa.

General Assembly Subcommittees

Students are expected to discuss and adopt resolutions for action dealing with international issues based on the title of their specific committee. Each committee is about 50 to 60 students in size. The Secretary General may recommend the resolutions from these twelve committees for consideration before the General Assembly. There are twelve G.A. Committees:

o Political & Security Committee A & B
o Council for Economic Advancement A & B
o Social, Humanitarian, & Cultural Committee A, B & C
o Environment & Technology Committee A & B
o Legal Committee A & B
o World Health Organization


A BLOC is a group of countries that come together to work toward a common goal, typically to promote economic, social, political, military, and cultural cooperation. Most BLOCs are formed by region, and countries are often in more than one BLOC. The view of a particular nation must always take precedence over a BLOCs’ views, unless the country feels it will receive some benefit from its continued adherence to a BLOCs’ views.

o Middle Eastern and North African Summit
o Asian Summit
o African Summit
o European Summit
o Pan-American Summit

Security Council

Students will react to and develop resolutions to world situations. Some of the topics are provided prior to the conference, while other emergency situations will be presented during the conference.

Historical Security Committee (HSC)

Similar to the Security Council, but the simulation will be a reenactment of a specific period in history.

Nation Building Committee (NBC)

Students will develop a comprehensive plan for the development of a nation at a specific time in history. Students will be assigned to represent the interests of the various nations and interested parties involved with the creation of the new state.

International Criminal Court (ICC)

Students will present and judge four cases dealing with alleged crimes committed by historical world figures. Students are expected to research each historical figure and determine for themselves their guilt or innocence. Student participants will present one case and deliberate the other three.

International Court of Justice (ICJ)

Students will present and judge four cases dealing with international incidents between nations. Cases are based on historical precedent. Student participants will present one case and deliberate the other three cases. Justices of the Court will elect one person of the committee at the Conference to serve as the Chief Excellency of the International Court of Justice for the following year.


This group of students engages in a variety of digital media to document happenings of the conference, educate about world events, and serve as an underlying connective force between all delegates. Space is highly limited, and students are encouraged to already possess existing skills (e.g., photography, video editing) in order to join.
