The United Nations International School of Hanoi is an international school in Hanoi, Vietnam. It is a private, non-profit organization founded in 1988 with the support of the United Nations Development Programme in Vietnam (UNDP) with the aim of providing an education to the children of UN staff and others. It is one of two UN schools in the world, with its sister school, United Nations International School, located in Manhattan and Queens, New York. It now caters to the children of diplomats, aid workers, businessmen, and other expatriates living and working in Hanoi. UNIS is regarded as of the most prestigious international schools in Asia. Classes range from pre-school to high school, and the IB Diploma is available to students in grade 11 and 12. As of May 2018, there were 1123 students with 66 nationalities speaking 44 different languages. The school maintains a 20% cap for any one nationality, which was put in place in order to maintain a truly international and culturally diverse atmosphere. There are teachers from 27 countries with 88% from the UK, USA, Australia, New Zealand, Ireland and Canada. Class sizes at UNIS Hanoi range from 16 to 22 students depending on the grade level with mostly 8 classes per grade level. History For many years, the school was housed in a small building attached to the Hanoi-Amsterdam campus (a local Vietnamese high school). In 1999, the campus was moved to the UN buildings in Van Phuc; in 2004 the school was finally moved to the long-awaited, custom-built campus located in a new area on the outskirts of Hanoi called Ciputra Hanoi Estate. In 2012, the school opened its sports center that included two full-sized covered basketball courts, weight/dance rooms, and several multipurpose classrooms. Along with the opening of the sports center, a new center for the arts was also opened that included among many facilities, including a new theater and a recording studio. When the school was founded in 1988, there were fewer than 10 students in the first class. Since the late 80s, the school has seen significant growth. Up until 1999, there was no 12th grade. The demographic has changed significantly in the past 5 years, as only a handful of Vietnamese children used to attend the school. UNIS now offers the full International Baccalaureate program, from the primary level to the Diploma Programme in high school—the first school to do
