AIMsWEB Data Breach

District 109 would like to make our community aware of an incident involving one of our educational systems partners.

On July 31, 2019, education software and data systems provider Pearson announced that a system-wide data breach had occurred through its AIMSweb 1.0 software. The breach, which affected approximately 13,000 of its school and university clients, occurred in November 2018 and involved unauthorized access to first names, last names, dates of birth, and email addresses of AIMSweb users. Pearson representatives say they learned of the breech in March 2019 and they have no evidence that the compromised data has been misused. The company has worked with cybersecurity experts to fix the vulnerability in their software moving forward.

Pearson informed us that some District 109 students enrolled between 2004 and 2016 have had their information compromised as a result of the breach, specifically student names and dates of birth. No other information was compromised. The district no longer uses AIMsWeb and no current students were affected.

We take seriously our obligation to protect the personal identifying information of our students, faculty and families. We maintain a high standard of internal digital security and we limit the data we provide to vendors to only what is essentially required to fulfill a critical function. 

Should you have any questions, please contact Assistant Superintendent of Teaching, Learning, and Innovation, Scott Schwartz at
