The Education Authority is making “positive progress” towards restoring access to the C2K system, following a cyber attack on Thursday.
The system, which is managed by Capita, provides all the IT and online resources for schools across Northern Ireland.
The attack has left thousands of GCSE and A-Level students unable to access revision materials over the Easter break.
In a statement released on Saturday, a spokesperson from the Education Authority said that staff had been working “around the clock to rapidly develop and test a safe and secure solution“.
“We have started to roll this out in schools, with initial priority given to post primary schools and pupils in exam years.

“Work will continue over the weekend and Easter period to restore access across the estate. Details of arrangements will be communicated to pupils by their school as soon as possible.
“We apologise for the unavoidable disruption, but would reassure users, this essential security measure was taken to maintain the integrity of the system and safety of all users.
On Thursday the EA had informed schools of a potential IT issue, and administered a password reset, logging students out of the system and unable to access revision material provided by their teachers.
The statement continued: “We will continue to keep schools, parents/carers and pupils updated via EA website Education Authority and our social media channels.”
