Stockholm International School, gy

One of the few truly international schools in the Stockholm area. Offers education entirely in english and generally intended for the children of expatriates and diplomats, resulting in the majority of students being international. High quality teachers, keeps to the standard of most major international schools of the world. When I went here 2011-2012, the secondary school was located in a nearby office building, but we still had several classes in the main building. Both buildings are located downtown and are not particularly suitable as school buildings, in particular for younger children I imagine, as there is little outdoor property and no connected PE facilities. Nonetheless you won't find a school of this quality anywhere else in Stockholm.
