New research says the most popular public high schools are highly segregated. Credit:Virginia Star The academics examined levels of segregation in the catchments of public high schools, which they categorised as "popular" (full with waiting lists), "balanced" or "rejected" (where places are available), and looked at whether school policies contribute to segregation. The paper found there was a "rather straightforward link between the affluence of a community and the desirability of a community's school". "It is generally accepted that most private schools are segregated across the lines of race and income but our study showed that public high schools are also highly segregated," Dr Rowe said. "Particular parts of the population can't access certain public high schools. The gap between the well-resourced schools and the less-resourced schools is growing, which is problematic for educational equity and access."

David Hope, the president of the Northern Sydney council of P&C associations, said: "In recent times the department have enforced boundaries much more strictly. It's better for kids to be in environments where there's a mixture of backgrounds and abilities and it's better for [cohesion]." Dr Rowe said if a parent wanted their child to attend a popular school, they would plan for it for many years and were often prepared to move neighbourhoods for a school. "In other countries, there is minimal difference between schools so parents send children to the nearest school. In Australia, parents perceive schools to be so different to each other that they will sell their house and relocate for what they perceive to be a better school. This behaviour is quite normalised," Dr Rowe said. The paper suggests that schools should make at least 10 per cent of places available to students from outside the schools' immediate catchment areas. Dr Rowe said: "As part of this, we need to implement blind selection processes for a proportion of places available in a school, rather than competitive access based on testing, academic or sporting merit".

But NSW Education Minister Rob Stokes said that children had a right to places at their local schools and that new school funding arrangements were accounting for inequality divides. "Public school enrolments tend to reflect the socio-economic status of their local community," he said. "The move to more needs-based funding includes an equity loading for socio-economic background." Mr Presland said Australian catchment "shopping" was driven partly by parents with "scant information" exaggerating perceived differences between schools but also Australia's school funding policy: "An unofficial motto in Finland is the best school is the closest school. In Finland they don't have private schools. No other country in the world does what we do in terms of funding private schools to the extent that we do". The paper says Australian education policy agenda "pushes and promotes parents to avoid low-performing schools, and be active and engaged in choosing the 'best' school," "For these reasons, the My School website was introduced in 2010, to enable parents to make more informed, calculated and rational choices, using the best available data."
