THSMUN is one of the largest student-run high school MUN conferences in Southern California. We usually host around 1200 students from 30 different middle and high schools. We are one of the few high school conference to offer exclusive middle school committees, and we also host specialized committees every year, including a joint-crisis committee and a European debate style committee.

THSMUN is a one day conference for novice delegates and two-days for advanced. The top advanced delegates will be awarded a gavel in each committee, and advanced delegations are eligible for Small and Large School Delegation Awards at our closing ceremonies. Every year, our conference supports a fundraiser spearheaded by one of our senior capstone teams. Our conference and program promote collaboration and diplomacy over competition.
