What age is a parent/guardian/teacher email address required and why?

As detailed in our Privacy Policy, learners who are 13 and under should only use iDEA if they have confirmed that their parent, guardian, carer or teacher has granted them permission to access iDEA. To confirm they've had permission, they will need to provide the name and email address of their parent, guardian, carer or teacher. They will be prompted to enter the parent/guardian/carer/teacher email address after they have signed up and before they start doing iDEA Badges.
