The PREVENT duty is the duty in the Counter-Terrorism and Security Act 2015 on specifies authorities, in the exercise of their functions, to have due regard to the need to prevent people from being drawn into terrorism.
The government have recently launched a new website aimed at supporting parents in implementing the PREVENT Duty. There are some useful resources on the website including written advice and signposting to other organisations. For more information go to educateagainsthate.com
There are other good materials around these issues, like counter extremism videos, on the London Grid for Learning website http://counterextremism.lgfl.org.uk/
If you have any worries or questions relating to this and are worried about your child, please contact school, or phone 101 to speak to the Police who have specially trained PREVENT officers.
