Thousands of teaching assistant jobs should be cut to help claw back millions of pounds wasted running schools, according to an internal Government report.
The analysis by former WH Smith chief executive Richard Handover said: "Financial efficiency... is not seen as a core responsibility of management at any level."
He suggested that 40,000 teaching assistant posts should be slashed.
According to the BBC Politics Show, the report cites an example of one primary school spending £50,000 on three toilets when it should have cost a tenth of that amount.
Another forked out £35,000 for a photocopier which would normally have cost £1,000.
Schools minister Vernon Coaker told the programme that these were "isolated" examples and insisted that teaching assistant jobs would not be cut.
He said: "The report suggested to us a number of things that we can do to tackle inefficiency, to bring good value for money."
Mr Coaker went on: "I think what the taxpayer will be pleased about is the investment that we've made in schools and they will be pleased to see that we plan to continue that investment."
Brian Strutton, National Officer of the GMB Union said suggesting the job cuts was "scaremongering, ill informed and out of date".
"The report on which this story is based does not properly recognise the work of teaching assistants and its conclusions are largely discredited," he said. "There is other strong evidence of the valuable role support staff play in our schools."
