Model United Nations is one of the most widespread academic activities for secondary students worldwide. Students are assigned a country, debate a real issue in a simulated UN committee, and work toward a draft resolution that must survive a vote. Unlike competitive debate, success depends less on persuading a judge than on articulating a national position clearly while building coalitions and producing documents that can actually pass.
Two tiers of conference matter most to Irvine families. The first is NHSMUN, run by the nonprofit IMUNA each March in New York City. NHSMUN 2027 offers two identical sessions - March 12-15 and March 17-20 - with schools choosing one and some committees meeting at United Nations Headquarters. It is known for academic depth, detailed background guides and position paper feedback. Schools register delegations of up to 50 students at $145 early (through August 31, 2026), $155 regular (September 1 to October 31) or $185 late, plus a $95 school fee and $95 per country or role requested. Early registration opens May 14, 2026.
The second tier is California’s large university conferences, led by BMUN at UC Berkeley - founded in 1952 as the world’s first MUN simulation. Its 75th session runs March 5-7, 2027 for over two thousand high school students, with countries assigned first-come, first-served and an adult advisor required.
Newcomers should start locally, learn parliamentary procedure, then attempt BMUN before travelling cross-country.
