The DfE has launched new guidance which states that from September 2013, schools will be banned from using pupils' biometric data without first obtaining parental consent. Pupils will also be allowed to refuse to participate in any biometric data system used in their school. 

Schools minister Nick Gibb said the guidance was being isued because 'children’s biometric data was sensitive personal information and parents must have the right to prevent its use by schools and colleges'. 

The guidance is currently under consultation for 'clarity' ahead of its final publication later this year. The consultation will close on 3 August.

Schools may use biometric data systems to remove the need for pupils to carry cash and to speed up procedures such as registration. Education lawyers from Browne Jacobson Solicitors explain what to do if parental consent is withheld (published 2008).
