THE school reforms proposed by the Federal Government bear little relationship to David Gonski's original reform recommendations, the Independent Education Union said on Friday.
Concerns that the reforms that remain on the table for just over a week were raised four days after new Education Minister Bill Shorten was sworn in on Monday.
The former union leader is now facing heated criticism over how far the reforms have strayed from Mr Gonski's original proposal.
Chief among the union's concerns were that the proposed models did not actually include the costing of delivering learning needs in remote or small schools or to indigenous students or those from a non-English speaking background.
Union federal secretary Chris Watt said the model currently on the table was "a long way short of Gonski's $6.5 billion per year", despite the additional funding on offer.
Mr Watt said there remained much to be concerned about, including the long-term increases pushed out to "three governments from now", to risks around the flexibility for reallocation of funds already promised.
"While an additional $15 billion would be welcomed by schools and their communities over the period to 2019, the amount is not revolutionary and the allocation model is looking increasingly political rather than transparent and robust," he said.
"The IEU is concerned about threats to members' wages and conditions in the next couple of years, and many critical issues remaining unresolved."
It came as Mr Shorten told ABC Radio he expected to still complete negotiations with all remaining states territories within the week left.
He said he remained open to talks with different jurisdiction, but would not commit to extra funding allocations for any state or school sector.
