The Labour Party has released correspondence from school boards of trustees to Education Minister Anne Tolley which show nearly all fault or oppose national standards.
The Government has developed standards in literacy and numeracy which primary school children will be measured against.
Labour's education spokesperson Trevor Mallard obtained the e-mails and letters under the Official Information Act.
Mr Mallard says out of 51 items of correspondence to Mrs Tolley, one is neutral, one is supportive and 49 range from concerned to scathing.
Mrs Tolley said in Parliament on Thursday she knows from attending the annual conference of the school trustees associations that they are supportive of the standards.
However, Mr Mallard says Mrs Tolley is living on another planet and the more the boards get to know about the standards, the less supportive they are.
