"This work will continue over the coming days, as we move to stand the system back up in all schools as soon as possible.

"Thank you for your patience and understanding.

"We will continue to provide updates on our social media channels and via the EA website www.eani.org.uk which includes an FAQs section in relation to this cyber security incident,” the EA said in a statement on Easter Sunday.

This follows confirmation on Good Friday that it had been the target of a cyber attack.

The EA said: “As soon as we became aware of the incident, the system managers, Capita, took immediate steps to contain the issue and begin a full investigation.”

It said it was not clear if personal data had been compromised but that it was taking the matter ‘very seriously’ and engaging with the Information Commissioner's Office.

A full password reset was carried out as a critical security measure.

The attack has caused disruption to pupils preparing for examinations.

“We understand and sincerely apologise for the impact on staff and pupils; particularly pupils who may be preparing for exams or completing coursework during the Easter period,” the EA said.
