Under UK GDPR, and as Controller, you must have a lawful basis for processing personal data (and remember that anything you do with personal data – including storing it or deleting it – counts as processing). UK GDPR won’t make processing lawful that would otherwise be unlawful, but it can prevent you from doing something you might otherwise expect to be able to do, if you can’t identify an appropriate lawful basis that applies. These are set out in Article 6(1) of the legislation:
Processing shall be lawful only if and to the extent that at least one of the following applies:
Many people believe – incorrectly – that the lawful bases are set out hierarchically; that a Controller should start at the top of the list and work down until they find a lawful basis that applies. Often, this means that they rely on consent, but this may not be the best choice and, in fact, should not be used if the Controller would process the personal data whether the Data Subject wanted them to or not: it must be as easy to withdraw consent as it is to give it.
As an Education Provider, a Controller will often be required to comply with a legal obligation or be performing a task carried out in the public interest, and so these lawful bases should be considered first for regular and systematic processing of Pupil personal data.
Where an Education Provider is carrying out processing of Personal Data not linked to the performance of their tasks as a public authority – for example, the production of School Leaver hoodies – they may be able to rely upon their legitimate interests.
Only where the Data Subject has a genuine choice and where it can be freely given and withdrawn at any time should consent be relied upon as the lawful basis for processing of Personal Data.
