United World College of the Atlantic (UWC Atlantic), commonly known by its former name Atlantic College, is an independent boarding school in Llantwit Major in Wales. Founded in 1962, it was the first of the United World Colleges and was among the first educational institutions in the world to follow an international curriculum. It helped create the International Baccalaureate Diploma Programme in the 1960s.
It is attended by approximately 350 students from more than 90 countries, with students including refugees and victims of war, members of persecuted communities, and members of royal families and political dynasties from around the world. The majority of its students are selected internationally through their National Committees which facilitate nationwide selection processes across the world in over 120 countries, and help fund student education through partial or full scholarships. Over 65% of students who apply through these national committees receive some form of scholarship or financial aid awards.
