Funding analysis prepared for the NSW Teachers Federation shows the NSW Government has been underfunding its own government schools, Catholic Schools NSW (CSNSW) said today.

The study - by education analyst Adam Rorris - concludes that the NSW government school system this year received $470 million less from the NSW Government than is needed to meet the state's share of the Schooling Resource Standard (SRS), the benchmark used to fund every student in Australia.

“This shortfall follows the so-called Gonski funding agreement signed by the NSW Government with then-Prime Minister Julia Gillard in 2013,” CSNSW Chief Executive Dallas McInerney said.

“The NSW Education Minister at the time was Adrian Piccoli - now with the University of NSW’s Gonski Institute for Education.

“During Mr Piccoli’s tenure as Minister, funding growth for NSW public schools slowed to 6.8% over three years while the Federal Government increased its contribution by 16.4% over the same period.
