Australian independent schools differ from those in the United States as the Australian Government provides funding to all schools including independent schools using a 'needs-based' funding model. This model was based on a Socio-Economic Status (SES) score, derived by selecting a sample of parents' addresses and mapping these to various household income and education data points collected from the national census conducted every five years. In 2013, after release of the (first) Gonski Report, the funding formula was changed to compute individual school funding compared to a School Resourcing Standard (SRS).
