The UK’s independent authority set up to uphold information rights in the public interest, promoting openness by public bodies and data privacy for individuals.

The ICO has been made aware of a data breach involving the Capita SIMS system that has affected a number of schools who use their services. We understand that Capita have added messages to the system to update schools and to help them identify if their data has been involved.

Schools should establish if they have been affected by the breach and if so assess which pupils’ data have been affected and how.

Under the GPDR, which came into force on 25 May 2018, controllers have an obligation to report data security breaches to the ICO unless there is unlikely to be a risk to individuals. Before 25 May 2018 there was no legal obligation to report to the ICO.

If your school has been affected by the Capita SIMS incident and you have enough information to establish that there may be a risk to your pupils or parents, you should report the breach to the ICO. If we need further information we will be in contact with you.

You should consider how your pupils or parents may be affected by the breach. If you think there is a high risk to their rights and freedoms, you need to tell them about the breach without delay. You should tell them about any steps you are taking to mitigate the effects of the breach and provide them with advice on what to do to protect themselves.


Take our self-assessment to determine whether your school needs to report to the ICO.
