The United Nations International School (UNIS) is the school of the United Nations, and is a Pre-K-to-12th grade, coeducational, International Baccalaureate, college-preparatory day school. Founded in 1947 by a group of United Nations parents to provide an international education for their children, UNIS has grown into an internationally recognized educational institution. Today, UNIS has 1,450 students and is located in Manhattan. UNIS was one of the founding schools of the International Baccalaureate (IB) and was among those awarding the first diplomas. The comprehensive Pre K-12 curriculum prepares UNIS students for the IB, and the school’s internationally recognized academic standards enable our students to study in top colleges and universities in the United States and worldwide.

Our students represent 109 countries, and are offered far more than solid grounding in classic and contemporary academic discipline. The UNIS international education enables students to become cognizant of the differences among the world’s people and to work together for the benefit of humankind. 

Campus Information
