Pearson reports data breach to districts across country

Oxford, Mississippi (January 10, 2020) — Oxford School District recently learned of a data security incident involving the AIMSweb 1.0 platform, a student assessment tool owned by Pearson Clinical Assessment.

According to information provided by Pearson, this unauthorized access occurred in November 2018 and Pearson support staff identified the breach in March 2019. In total, approximately 13,000 districts across multiple states were affected by this data breach. Pearson reportedly began notifying affected schools and districts in July 2019, however, OSD did not learn of the incident until much later.

Pearson technical support reported the compromised OSD data includes both student and staff records. The student information included first name, last name, and ID number. The staff information included first name, last name, and email address. At this time, there is no evidence, according to Pearson support staff, that this compromised data has been misused.

Oxford School District is committed to the protection of student and employee data, and will continue to work to improve data handling and storage procedures. In response to this incident, Pearson deactivated the AIMSweb 1.0 platform, and continues to investigate and work with law enforcement. All OSD data will be deleted from the AIMSweb 1.0 platform when Pearson is legally permitted to do so.

Again, there is no evidence that the information described above has been misused, however, Pearson is offering complimentary credit monitoring from Experian for one year for affected individuals as a precautionary measure.

Additional questions should be directed to Pearson at 866-883-3309 or email as district personnel cannot provide any additional information.
