The Jerome School District canceled school for all students on Monday in the wake of a cyberattack over the weekend.

The district’s technology team and cybersecurity experts are “working around the clock to address this situation,” Superintendent Brent Johnson wrote in a message to families. Closing school on Monday will give the team time to restore, verify and reinforce the network infrastructure.

“Because of proactive security measures already in place, we were able to quickly isolate the disruption,” he wrote.

According to the district, student devices and data remain secure. The statement did not mention if staff data was compromised.

“Out of an abundance of caution, staff devices are undergoing thorough security clearance and maintenance before being brought back online,” Johnson wrote.

The district will provide more information “as soon as it becomes available” regarding the school schedule for the rest of the week.

Jerome, along with many other school districts in Idaho and around the country, was impacted by a December 2024 cyberattack on PowerSchool, a cloud-based data company.

In January 2025, the district released a statement confirming that “all current and previous JSD student and staff data was accessed” in the Powerschool breach.
