IB Diploma Programme in the context of "International Baccalaureate"

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.

St Leonards School is a co-educational private boarding and day school for pupils aged 4–19 in St Andrews, Fife, Scotland. Founded in 1877 as St Andrews School for Girls Company, it adopted the St Leonards name upon moving to its current premises, the site formerly occupied by the University of St Andrews’ St Leonard's College, in 1883.

The school emerged from the St Andrews Ladies' Educational Association which was established in 1868. One of the school's founders was Lewis Campbell, chairman of the college council for many years and a Classics professor at St Andrews University who advocated for higher education for women. Consequently, from its earliest days, the college's senior students were encouraged to prepare to matriculate and enjoyed close links with various courses offered at the University of St Andrews; in 1892, the Fifeshire Journal asked its readers: "Who is to enjoy the proud distinction of being the first matriculated girl-student of St Andrews?" St Leonards remained an all-girls school until 1999, upon which it became fully co-educational. As an IB World School, St Leonards offers the International Baccalaureate's Primary Years, Middle Years, Career-related and Diploma programmes alongside the English-system GCSE/IGCSE. It is one of only two schools in Scotland to teach an IB curriculum throughout.
