Launching the government's revised code of practice on council/school relations, Ms Morris said: 'Paperwork can get in the way of teaching and preparing for lessons. We are cutting out unnecessary form-filling and I am calling on local authorities to do the same.
'Some are sending too many pieces of paper to schools. Too many repeatedly ask schools for the same information.'
The communications standard in the revised code commits councils to stamping out duplication.
Ms Morris said: 'Some authorities are already well ahead of the field, and this communications standard will lend our support for their actions. But for many authorities, meeting the standard will be a challenge. We will offer our support through examples of good practice on our website and we will ask Ofsted to monitor the implementation of the standard on the ground.'
