Data breach delays start of Sumner County school year

One Middle Tennessee school district is delaying the start of the school year due to a data breach in its computer network.

School officials in Sumner County discovered the breach in its computer network earlier this week and subsequently revised the district calendar so the problem could be resolved before students return to class.

New student registration was originally scheduled to open July 22 but has been postponed to Aug. 4 and 5. The first day of school was pushed back to Aug. 10.

Sumner County Schools Superintendent Scott Langford sent a letter to families, which included the following:

Dear Parents,

We wanted to share some information about an occurrence that will impact the start of our school year.

On July 20, 2026, Sumner County Schools became aware of unauthorized access into our network. We promptly notified local and federal law enforcement and the Department of Education and engaged third-party forensic specialists to investigate and respond to this matter. Please understand that our team is diligently working around the clock to minimize the impact to schools and overall operations.

The Superintendent shared this message on the district’s Facebook page and parents swarmed the comments section expressing concerns about their personal data being exposed. Some parents noted that they have already registered their children despite the announcement saying registration was delayed until the first week of August. They’re concerned that their personal information might have been exposed during the breach.

Sumner County Schools did not respond to WPLN’s request for comment.

Here’s what are other midstate school districts told WPLN News they are doing to prevent similar threats.

• Metro Nashville Public Schools: “We continually evaluate our security posture and regularly implement enhancements based on evolving threats, industry best practices, and guidance from cybersecurity partners.”
• Cheatham County Schools: “We already have a cybersecurity company in place that continuously monitors our network and systems to help identify and prevent suspicious activity.”
• Rutherford County Schools: “We have robust safeguards in place.”
