Approximately 1,250 Bakersfield City School District employees' personal information was accidentally exposed last week in a data breach, the district said on Tuesday.

BCSD officials confirmed a report containing personal information was inadvertently uploaded as an attachment within documents for a school board meeting.

The district said it was notified on Thursday, Nov. 9 that the report was uploaded, and it was online for about three hours until it was taken down.

District officials notified employees on Monday, Nov. 13 after contacting legal counsel and the Kern County Superintendent. Staff members that were affected included some certificated employees and substitutes.

BCSD said it is working to protect any employee information that may have been compromised, including offering credit monitoring services to anyone involved.
