Two weeks ago, The Guardian revealed how the Department for Education is monitoring the social media activity of some of the country’s leading education experts. Now evidence has emerged that the monitoring is much more widespread, covering even the lowest paid members of staff.

Ordinary teaching and support staff said this weekend that they were “gobsmacked” and angry after discovering that the department had files on them. Many outraged educators have rushed to submit subject access requests [SARs] compelling the DfE to release any information it holds under their name, after discovering there were files up to 60 pages long about their tweets and comments challenging government policy or the schools inspectorate, Ofsted.
