PowerSchool will begin sending notifications to affected people in the next two weeks, per a department update posted Wednesday afternoon.

The updates follow a virtual call Tuesday evening between the PowerSchool CEO and school leaders.

PowerSchool provides the statewide student information system to North Carolina and thousands of schools globally. It contains data on teachers, as well. The state will shift to Infinite Campus for the service July 1, a decision made in November 2023 — well before the hack — in response to state legislative requirements to modernize the system.

PowerSchool has said the hack was isolated to two tables that mostly contain personal information, such as contact, limited medical and limited grade information. North Carolina officials have said they don’t believe medical information was compromised in the state.

The California-based company has spent weeks trying to identify all of the data accessed by hackers in December and who exactly is affected. It's unclear how many people had data breached — and what that data was — in North Carolina. WRAL News reached out to PowerSchool with several questions. The company declined to answer many of them and reiterated the plan to provide affected people with two years of credit monitoring.

A PowerSchool spokesperson said the company was "unable to comment on regional impact" when asked how many North Carolina teachers and students had any data breached, not just social security numbers.

The company did say that the impact varies across customers because customers have different requirements and can modify the types of information available.

The breach occurred on PowerSchool’s end when a contractor’s account was compromised and affected the company’s customers worldwide.

Last week, DPI said all schools in North Carolina that have ever used PowerSchool were affected by the breach “to some degree.” Current and past students and teachers had data in the system.

The company plans to offer two years of free credit monitoring via Experian to individuals’ whose personal data was exposed.
