TESMUN is an academic simulation of the United Nations in which students act as delegates from various countries as well as representative members of Nepal's House of Representatives. They try to tackle real-world problems using the policies and viewpoints of their respective countries while acting as Nepali political leaders. TESMUN 2023 is a forum for students to investigate, enquire, and discuss. The Excelsior School, like many universities, high schools, and non-profit organizations, has organized Model United Nations sessions to empower students and offer them an interactive platform.
