South Australian Liberal leader Steven Marshall signed up to a dud deal for South Australian students, says Australian Greens spokesperson for Schools Senator Penny Wright.

"Steven Marshall has abandoned SA schools and is seriously risking the economic future of this state," Senator Wright said.

"Investing in our students is the best investment we can make for South Australia.

The Abbott Government's independent public schools system will create a hodgepodge of different schooling systems all around the country, Australian Greens spokesperson for schools Senator Penny Wright said today.

Questions asked by Senator Wright in estimates hearings last night revealed each state and territory will be able to decide their own application criteria for independent public schools and develop their own levels of autonomy.

The Abbott Government will spend $300,000 in rushing a review of the national curriculum before implementation is complete, paying reviewers Kevin Donnelly and Ken Wiltshire $429 each per day.

Questions asked by Australian Greens spokesperson for Schools Senator Wright in estimates hearings today revealed the full costs of the review.

"This review is nothing more than an ideological exercise by the Minister based on his own paranoia about a "left wing bias" in schools," Senator Wright said.

During Senate Estimates, Senator Wright asks questions relating to deductible gift recipient status and its availability to government schools. 

Senator WRIGHT: I am interested to know a bit more about what process of review may have occurred or did occur before the decision was made to cut funding to trade training centres. Are you aware of any review process? You have said it was done in the context of MYEFO. We know it was actually an election promise. Are you aware of any review that was done by the decision makers?

Ms Paul : My evidence was comprehensive that it was a clear election commitment and then that was followed up through the normal budget process which led into MYEFO.

Boosting teacher salaries and improving professional support must be the focus of the Abbott Government's review of teacher training, says Australian Greens spokesperson for Schools, Senator Penny Wright.

Senator Wright said she was concerned the review panel was instead a way to point the figure at teachers and shift the focus from the Government's poor policies.

"First Christopher Pyne blamed the curriculum for sliding education standards. Now he's blaming the teachers," Senator Wright said.
