UNIS–UN is held annually in the United Nations General Assembly Hall, giving students the unique opportunity to engage with peers from around the world on complex global issues. This two-day conference is entirely organized by the UNIS–UN Committee, composed of approximately 100 Tutorial House students. Since 1977, the conference has challenged participants to think critically, collaborate across diverse perspectives, and navigate the complexities of running a large-scale international event.  

UNIS–UN also welcomes UN leaders and global experts to share their knowledge and insights, offering students experiences rarely available elsewhere. Each year, the conference centers on a single guiding theme of global importance, bringing together students from five continents representing UNIS and other invited schools.
