It comes as at least one school in the North has warned parents it would have a particular focus on preparing for the National Assessment Program Literacy and Numeracy testing once children return after the Easter break.

President Terry Polglase said with a little over a month until the testing of year 3, 5, 7 and 9 students gets under way from May 15 to 17, it was an opportune time for the country to evaluate ``the pros and cons of the high stakes testing''.

Mr Polglase said reports over the weekend demonstrate the opposing views of Prime Minister Julia Gillard and opposition education spokesman Christopher Pyne and it raised questions about the value of the testing.

And especially if the opposition was to come to power after the next federal election.

``We need a united position as schools, departments and governments are allocating considerable time and resources to preparing for May testing,'' Mr Polglase said.

``The curriculum is being limited and the time taken by schools to prepare for this one test cannot be justified on educational grounds.''

Save Our Schools national convenor Trevor Cobbold said NAPLAN had caused schools around the country to undergo a ``testing barrage'' in term 1 to ensure they got good results on the MySchool website.

Mr Cobbold said some schools were spending as much as 150 hours preparing for the tests at the expense of other subjects.

``Test scores do not equal education,'' he said.

It comes following a visit last month to the University of Tasmania by internationally renowned education expert Professor David Berliner who said NAPLAN had ruined the US and would do the same in Australia if it continued.
