The Home Office (for police forces nationwide) Counter Terrorism Police Headquarters (for Prevent), Department of Health and Social Care (for all healthcare providers) and Ministry of Housing, Communities and Local Government (for all local authorities regarding their social care functions) should issue a nationwide reminder to all agencies considering the risk that children pose to others of the importance of respecting the insight offered by the child’s school if they raise concern about the severity of risk that the child poses to others. As was the case with AR at The Acorns School, teachers will often spend more time observing the child (and their interaction with peers) than is available to other professionals. Warnings from teachers and/or schools with particular expertise (including but not limited to Pupil Referral Units) should be given particular weight.
