Stockholm International School (SIS), formerly known as the Anglo-American School of Stockholm, is an international school located in Stockholm founded in 1951. The school teaches a International Baccalaureate education to primary, middle, and high school students. SIS has two sites: the Primary School is housed on Johannesgatan next to in the centre of Stockholm. The Middle and Upper Schools of SIS are housed in Norra Latin on Drottninggatan.
As of 2026, the head of the school MarÃÂa (Marisa) Isabel León passed away. David Osler has been appointed as interim director.
Gisela Dietze founded the English School, which initially, in 1951 occupied a campus on DjurgÃÂ¥rden. The school had 58 students from 15 countries by the end of that year. The school was renamed to Anglo-American School of Stockholm in 1964 and then to International School of Stockholm in 1978. The student body numbered 288 by 1967, when SIS moved to its current location on Johannesgatan. The International School of Stockholm sought to have the International Baccalaureate Programme implemented at the school in 2000 and the first IB students started at the school in 2001. In 2004, the school changed its name to Stockholm International School.
