The Montessori School was founded by Mrs W. M. Duyker-de-Vries in 1962 and is the oldest Montessori School in Australia. It is the first Montessori school in Western Australia to include a Secondary school for students from 12 to 18 years and the first Montessori School in the world to offer the International Baccalaureate (IB) Diploma course, an internationally recognised university entrance qualification. Our school is located in Kingsley, in Perth's northern suburbs. It enjoys a scenic bushland setting, on top of a hill, overlooking Lake Goollelal. Initially the school catered for pre-primary children only, with a primary section being added in 1965 and secondary in 1972. The Montessori School became an International Baccalaureate (IB) school in 1993.
