WATCH: What is GDPR?
A spokeswoman for the Information Commissioner's Office (ICO) said that it had engaged with the DfE about its processing of pupil data in the past "and continues to do so".

"We understand that the DfE is reviewing its processing of pupil data as part of its GDPR preparations. And the ICO will continue to engage with the DfE on this."
