The Highline School District class action settlement received preliminary approval from the court on December 19, 2025 and covers approximately 94,102 individuals residing in the United States who received a notice from the district that their private information may have been implicated in the September 2024 data breach.

The court-approved website for the Highline School District data breach settlement can be found at HSDDataIncident.com/.

According to the website, Highline settlement class members who submit a timely, valid claim form and provide documented proof of out-of-pocket losses are able to receive a one-time cash payment of up to $5,000. Per the agreement, these losses must have been incurred between the time of the breach and submission of the claim form. Covered losses include those related to fraud or identity theft, credit monitoring, bank fees, or other miscellaneous expenses, such as mileage or postage, that have not previously been reimbursed by a third party.

In the event that attorneys’ fees, settlement administration costs, lead plaintiff service awards, and compensation for class members exceed $650,000, the settlement agreement explains that payments to class members may be subject to a prorated decrease.  

Highline settlement class members may elect to receive their payouts via check or electronic payment. The agreement states that all checks must be cashed within 90 days of issuance before they expire.

The Highline School District class action lawsuit alleged that the district failed to implement reasonable data security measures to protect the private information stored on its systems, leading to a targeted cyberattack on or around September 7, 2024. Per court documents, data associated with current and former students and employees of Highline that may have been compromised during the breach included names, addresses, dates of birth, Social Security numbers, driver’s license numbers, financial account information, employment information, digital signatures, medical information, health insurance information, student records/demographic information and grades.
