What is Model United Nations?
Model United Nations (often abbreviated MUN or Model UN) is an academic simulation of United Nations bodies. Students take the role of country delegates on UN committees and work through structured debate to negotiate and pass resolutions on real international issues. The format dates to the 1920s — predecessor Model League of Nations programs ran at Harvard, Princeton, and Oxford — and has expanded into a global circuit of competitions and educational programs reaching hundreds of thousands of students each year.
MUN is deliberately distinct from real UN proceedings. Conferences compress timelines (real treaty negotiation takes years; a MUN topic resolves in days), simplify rules of procedure for pedagogical clarity, and add competitive scoring that real diplomatic bodies don't use. But the substantive work — researching a country's foreign policy, building coalitions, drafting binding language, anticipating procedural challenges — closely mirrors the work career diplomats actually do.
Today, the largest MUN conferences in the United States draw 3,000+ delegates. International events like WorldMUN rotate cities annually and attract delegates from 50+ countries. The educational research literature on MUN consistently finds gains in public-speaking confidence, civic knowledge, and policy literacy — particularly for students who participate over multiple seasons.
How a MUN conference works
A standard MUN conference runs across two to four days. Delegates arrive with country assignments and prepared position papers — short documents (usually one to two pages) that summarize the country's position on the committee's topics, the country's history of relevant action, and the country's proposed solutions.
Conference flow proceeds through formal rules of procedure (commonly UNA-USA, THIMUN, or a custom variant). Each committee opens with a speakers list — short opening speeches from each delegation — then moves through moderated caucuses (structured topical debate) and unmoderated caucuses (open negotiation among delegates) to build working papers, then draft resolutions. Resolutions go through amendment and a final vote. Strong committees pass at least one substantive resolution.
Throughout the conference, the dais — the chair, vice-chair, and rapporteur — score delegates on substantive contribution, procedural fluency, diplomatic conduct, and resolution authorship. Awards are typically given for Best Delegate, Outstanding Delegate, Honorable Mention, and Verbal Commendation. Many delegates also pursue awards-portfolio strategies (cultivating reputation, mentoring weaker delegations, sponsoring multiple draft resolutions) that compound across multi-year MUN careers.
The roles in Model UN
Three core roles structure every MUN conference: delegates, dais (chairs), and secretariat. A fourth — crisis staff — appears in crisis-format committees.
Delegates
Delegates represent an assigned country (or, in crisis, an assigned individual) on a committee. Their job is to faithfully represent the country's foreign-policy position, negotiate with other delegations to advance that position, draft resolution language, and contribute to procedural and substantive debate. Strong delegates research deeply, speak frequently and well, build coalitions, and write clear treaty-style language.
Chairs and the dais
Chairs (also called moderators or directors) run committees. The dais — chair, vice-chair, rapporteur — enforces rules of procedure, manages the speakers list, calls motions to a vote, and scores delegates. Chairs also write the background guide before the conference and often co-design topic-specific crisis updates during the committee.
Secretariat
The secretariat runs the conference itself. The Secretary-General leads overall vision and operations; Under-Secretaries-General oversee committees, training, crisis, logistics, and outreach; Directors run specific committees. At university conferences, the secretariat is typically a year-long appointment for students who have served as chairs in previous years.
Crisis staff
Crisis committees add a crisis director and crisis staff who manage real-time crisis updates: drafting news bulletins, responding to delegate notes, generating cabinet-level NPC responses, and escalating or de-escalating the crisis arc to maintain pace and stakes. Crisis staff is one of the most demanding MUN roles and a common path to secretariat positions.
Major MUN conferences
The competitive MUN landscape is dominated by a circuit of well-established conferences. Each has its own scoring norms, procedural variant, and culture, and the strongest MUN programs structure their season around several circuit conferences plus regional events.
In the United States, the headline conferences include Harvard Model UN (HMUN), the National High School Model UN (NHSMUN), the North American Invitational Model UN (NAIMUN, hosted by Georgetown), the Berkeley Model UN (BMUN), Princeton Model UN (PMUNC), Yale Model UN (YMUN), Stanford Model UN (SMUNC), and Boston University's BosMUN. World Model UN (WorldMUN), hosted by Harvard but rotating internationally, draws a global field. Beyond the elite circuit, hundreds of regional and high-school-hosted conferences serve more local audiences.
Internationally, The Hague International Model UN (THIMUN) defines the procedural standard for much of Europe and Asia, and large national conferences (Russian MUN, Indonesian MUN, Italian MUN, Spanish MUN) anchor regional circuits. Each major conference publishes detailed background guides; serious delegates and chairs treat the strongest of these as the authoritative committee-prep documents.
Skills Model UN teaches
MUN is unusual among extracurriculars in how directly it teaches durable career skills. Public speaking is the most obvious — delegates give dozens of structured speeches per conference under time pressure. Writing is a close second: position papers, working papers, draft resolutions, and crisis directives all require concise, formal, treaty-style writing.
Beyond the visible skills, MUN teaches research literacy (specifically, how to find and synthesize primary-source documents like UN resolutions, treaty text, and government statements), procedural fluency (rules of order generalize across professional contexts), and stakeholder-aware negotiation. The MUN-alumni base spans law, foreign service, journalism, consulting, NGO leadership, and elected office at notably above-average rates.
Recent education research on MUN (compiled in journals like the Journal of Political Science Education and the International Studies Perspectives) consistently finds significant gains in policy literacy, civic engagement, and academic confidence — particularly for students who participate over multiple years and across multiple committee types.
How to prepare for a MUN conference
Preparation for a strong MUN performance proceeds in roughly five phases. First, read the background guide — usually written by your committee's chair — thoroughly. It frames the topic, surfaces the procedural expectations, and signals what the chair will reward. Second, research your assigned country's foreign-policy position from primary sources: UN voting record, ministry statements, treaty obligations, and bloc affiliations.
Third, write the position paper. Most conferences require 1–2 pages covering background, country position, and proposed solutions, with primary-source citations. Fourth, prepare a 60–90 second opening speech that establishes your country's position and signals coalition openness. Fifth, learn the rules of procedure your conference uses well enough to use procedural motions strategically — not just to follow them.
Model Diplomat is built to compress all five phases. The country profiles cover foreign-policy positions and primary-source citations; the AI Search lets you research any topic with cited answers; the Position Paper Helper structures the paper to standard MUN format; the Debate Simulations let you practice against AI that argues real country positions.
