PUBLIC schools are not getting their fair share of federal schools funding because of an ''unfair and dysfunctional'' funding model inherited from the Howard government, according to a report to be released today.

The report, by Jim McMorrow, a former senior public servant and policy adviser and honorary associate professor at the University of Sydney, was commissioned by the Australian Education Union.

It will place further pressure on the Federal Government to scrap the controversial socio-economic status (SES) funding model introduced by the Howard government in 2001.

But Education Minister Julia Gillard and independent schools said the report was misleading because it ignored the contribution made by state and territory governments, which provide the bulk of funding for government schools.

The report, to be released at the union's national conference in Melbourne this morning, acknowledges the Federal Government has provided unprecedented levels of Commonwealth funding to all schools - including government ones.
