In July Pearson began notifying 13,000 school districts and universities that its AIMSweb product was breached in November 2018. Pearson discovered the breach in March. We're keeping a running list of Illinois school districts known to be affected by the breach below.

The breach included AIMSweb 1.0 accounts going back to 2001 (and possibly longer) and included students' names, emails and some birth dates and student ID numbers. In some districts teacher and staff info was also breached. Here's one of the notification letters Pearson sent to school districts.

Chicago civil rights law firm Loevy & Loevy has filed a class action suit against Pearson for this breach. If your child was affected, and you'd like to get in touch with the attorneys, you can email [email protected]. You can read the full legal complaint here.

In addition, according to the Chicago Tribune, "anyone interested in obtaining more information or wanting to set up free credit report monitoring should go to or call Pearson at 866-883-3309."
