The German School of Oslo is a German-language school in Oslo, Norway, and is led by Oliver Schaefer. It is located in Sporveisgata 20 at Bislett, and was opened in 1980. In the beginning, the school was located in the basement of the German Protestant Community of Oslo in Eilert Sundts gate 37, before it moved to Majorstuen School. In 1998, the DSO moved from Majorstuen to the disused Hegdehaugen Upper Secondary School, where it has been ever since.
