It is not illegal to take photographs of children in school, but photographs and video images of pupils and staff are classed as personal data under the terms of the Data Protection Act 1998.
Increasingly, technology is making it easier for pictures and images to be used inappropriately as printed material or on the web.
It is important that pictures/images of children taken by parents/carers are done so in a way that reflects the protective ethos of the school and that parent/carers are aware of their responsibilities in this matter.
Pictures/images of children in school should not be displayed on websites, in publications or in public places; this includes all forms of social media.
If you are found to be using images inappropriately, you could be prosecuted by the ICO
(Information Commissioners Office) and risk a fine of up to £500,000.
