According to the Model United Nations Institute, Model United Nations, also known as Model UN or MUN, is an extra-curricular activity in which students typically role play delegates to the United Nations and simulate UN committees. Thousands of middle school, high school, and college students across the country and around the world participate in Model United Nations, which involves substantial researching, public speaking, debating, and writing skills, as well as critical thinking, teamwork, and leadership abilities.
