The United World College in Mostar (UWC Mostar) is one of 18 schools and colleges around the world in the UWC (United World Colleges) movement. UWC is a global educational movement with the mission to make education a force to unite people, nations and cultures for peace and a sustainable future. The UWC movement was founded in 1962 with the opening of UWC Atlantic College, and now spans 18 schools and colleges across four continents, as well as 155 UWC National Committees who help to select students from their country. The majority of schools and colleges admit students exclusively for the last two years of school in order to complete the internationally recognised IB Diploma programme. A number of schools and colleges also offer a Foundation IB year to help students prepare for the rigorous pre-university course that is the IB Diploma, and several offer opportunities for students as young as 3 to experience an education focused on fostering peace and international understanding.
