The Department for Education's push for all schools to become academies is being looked at by regulators following concerns raised by the National Education Union (NEU).
The union had called in the Office for Statistics Regulation (OSR) to investigate evidence used by the government to reach its decision to bring in a fully trust-led school system.
In backing many of the union’s concerns around transparency and the quality of data used, the regulator has now written to the DfE’s chief data officer and chief statistician Neil McIvor asking for more clarity.
