"Nor have we told schools to remove disclaimers as described," Ms Cleaver said.
She said the inclusion of a disclaimer did not make a charter non-compliant. "In cases where a disclaimer statement has been included, the ministry will work with schools to ensure the charter is implemented," she said.
Mr Stevens and Mr Ferris said they were upset the ministry had tried to bully them and then denied it. "It almost discredits us again," Mr Stevens said. "It's like saying, 'You're imagining it, it didn't happen'. It did happen," he said.
"I don't really know what to say because I cannot believe that we're being treated this way by a group that we're supposed to be working with."
Mr Stevens said the school board of trustees would meet to discuss whether to remove the disclaimer from the charter. "My board's in a quandary. I've got a couple who want to take it out and I've got a couple who want to leave it in."
Mr Stevens said the Government had no problem riding rough-shod over schools because it had a strong majority in Parliament.
"When a government's got a majority that they've got, they can do what they please. It's a bit scary really.
"You'd expect when something as far reaching as National Standards are being brought into education, that the sector involved will be spoken to and consulted with but that's not even happening."
