AIMSweb data security breach

Dear Parents, Guardians and Staff,

Pearson Clinical Assessment notified Downers Grove Grade School District 58 today, Friday, August 9, 2019, regarding a data security incident related to their AIMSweb 1.0 product by an unauthorized third party. Our district is one of 13,000 Pearson clients affected by this incident, which occurred in November 2018. 

According to Pearson, the affected data was limited to the first name, last name and, in some cases, date of birth and email addresses of students, as well as the first name, last name and potentially the email addresses of staff. No test scores, performance data or other identifying student/staff information were part of the data incident. The data involved approximately 3,900 current District 58 students and an additional 1,300 former students who were enrolled between 2006-2019.

Although Pearson has provided no evidence that any data was misused, out of abundance of caution, our district wants to make you are aware of this incident.  Free credit monitoring service from Experian is available to any student who was enrolled in District 58 from 2006 to present. Pearson is providing this free service as a precautionary measure. Please see the below enrollment information:

If you have questions about the product please contact Experian’s customer care team at 866-883-3309 by January 31, 2020.  Be prepared to provide engagement number DB12466 as proof of eligibility for the identity restoration services by Experian.

As a school district, we take very seriously the security of all student, family and staff data. Only the most limited data is provided to vendors for required services. Contracts with outside vendors are closely vetted to ensure measures are in place at all times to safeguard that data. Pearson Clinical Assessment has worked with cyber security experts to evaluate the incident and assured us that changes have been implemented to prevent this from happening again with their product.

If you have questions, please contact Pearson Clinical Assessment at or District 58 Assistant Superintendent for Technology and Learning Dr. James Eichmiller at or 630-719-2768.
