2026 Lake County Schools: records error exposed about 47,000 student files
Data compromised
About 47,000 students: education records, individual educational plans (IEPs) and disability information. Social Security numbers and payment cards were not mentioned in the 10 November board reporting.
Technical writeup
Root cause
A parent filed a public-records request on 14 September 2026. On 23 October a district employee uploaded eight unredacted files instead of the redacted versions. The district first estimated about 1,800 records, then confirmed about 47,000, including files going back to the 2023 graduating class. On 3 November the district sued in Lake County circuit court to have the files deleted and to get a sworn statement. The district says one person holds the files. This was not a network intrusion.
