Education experts have slammed the government for spinning a report last month into city academies.
The report from PricewaterhouseCoopers (PwC) into 11 academies gave a mixed picture of thir success.
But the government’s response took “the most favourable view possible”, The Education Network (Ten) said.
The Ten study says the academies scheme is so expensive — at an expected £5 billlion — that it is “essential” for the government to evaluate it properly.
The organisation, which advises local authorities, called for “a far more open and honest approach to the presentation of information”.
The Department for Education and Skills said the PwC evaluation showed three quarters of pupils felt behaviour was better at their academy than its predecessor.
But Ten says the figures were inaccurate and misleading.
“In fact, PwC reports that 69 percent of pupils disagreed with the statement that ‘my behaviour is worse now than before I came to this academy’, which is not the same thing at all,” it said.
Ten also said apparent parental endorsement, based on ten academies, relied on a survey conducted before some had even opened.
