TESMUN is an academic simulation of the United Nations where students play the roles of delegates from different countries, as well as the people from the House of Representatives of Nepal. They attempt to resolve real-world problems with the policies and perspectives of their assigned countries. This TESMUN is a grand session of students where they research, inquire and debate. Like many universities, high schools, and non-profit organizations, The Excelsior School has also been organizing the Model United Nations' sessions to empower the students with the necessary skills for the 21st century.
