The extent of the secrecy surrounding decisions about academies has been laid bare by a Tes analysis highlighting the volume of information kept from the public.
Only 3 per cent of the documentation relating to one cycle of headteacher board (HTBs) meetings in October and November last year was published.
The eight HTBs across England advise and challenge regional schools commissioners (RSCs), whose powers include turning schools into academies and deciding who runs them.
During this cycle, the HTBs received 1,016 pages of documents, but only 32 pages of minutes were published.
And even when Tes obtained the full set of papers using the Freedom of Information Act, they were heavily censored, with most of the information blacked out in 295 pages.
