Many schools will receive huge increases next year in the form of these loadings, including the western Sydney schools Plumpton High, which will receive an additional $605,529, Cranebrook, which will receive $620,725 and Chester Hill, $853,767.

Peter Ezzy, principal of Plumpton High School, said the additional funding would be of ''huge benefit'', and gave him certainty for the years ahead. ''We're not used to getting this sort of money, we're always used to trying to do the best we can on a limited budget,'' he said.

But about 200 schools, many in low socio-economic areas and some that have received high levels of special program or equity funding this year, will receive slightly less in the form of loadings in 2014.

These include Mount Druitt Public School and Wiley Park Girls High School, which will each receive $50,000 less.

Department of Education and Communities director-general Michele Bruniges said the department had capped the maximum amount any school could lose at $50,000. ''As the money comes in, we know that the curve of Gonski funding increases, so depending on the data that we collect each year that funding shock won't be great in [2015] or [2016] as it was in [2014],'' she said.
