Oslo Waldorf School (Norwegian: Rudolf Steinerskolen i Oslo) is a Waldorf school located in the Hovseter area in the Vestre Aker district of West End Oslo, Norway. It is an integrated primary, middle and high school with around 550 pupils. Founded in 1926, it is one of the oldest Waldorf schools worldwide. It is generally regarded as one of the most prestigious schools in Norway and many of its alumni have been noted in the arts, politics and other areas of society. The school is an independent non-profit foundation governed by a board consisting of representatives of the teachers and parents, and it is a member of the Norwegian Association of Waldorf Schools.
In November 1921, two years after the first Waldorf School was founded in Stuttgart, Austrian philosopher Rudolf Steiner held two lectures on education at the Norwegian Nobel Institute in Oslo (then named Christiania), and the plan to establish a Waldorf school in Oslo was conceived. Among those involved was Bokken Lasson, who also became one of the first teachers when the school was established in 1926. The school was originally located in Oscars gate in the Frogner district. As of 1932, the school had 102 pupils. Due to financial difficulties, the school had to close in 1936. Vult Simon and Gulle Brun however continued to operate a small Waldorf school in their home at Makrellbekken. In the autumn of 1945 the school was reestablished, and was located in a barracks in Frogner Park. In 1949, the school moved to Smestad, and in 1962, it moved to Hovseter, where it is still located. Its building complex has been successively extended over the years in different architectural styles.
Prior to 1961, the school received no public funding, and was funded entirely by tuition and gifts as well as by idealistic teachers who worked for relatively little pay. The school became entitled to regular public funding under the Private School Act of 1970. Originally a primary school and later also a middle school, the first high school class was established in 1978.
