Such schools are typically operated by an independently elected school council or board of governors and range broadly in the type of school-education provided and the socio-economics of the school community served. Some independent schools are run by religious institutes; others have no religious affiliation and are driven by a national philosophy (such as international schools), pedogogical philosophy (such as Waldorf-Steiner schools), or specific needs (such as special schools). As of 2018[update], including independent schools run by Catholic religious institutes, of the 9,477 schools in Australia 1,140 schools (12 percent) are in the independent sector.
