Pearson Client Data Impacted

August 20, 2019

The Pearson Clinical Assessment company recently informed Glen Ellyn School District 41 that they experienced a data security incident related to their AIMSweb 1.0 product by an unauthorized third party. AIMSweb 1.0 tracks student academic progress and we are one of 13,000 Pearson clients impacted by this incident. District 41 has used Pearson services for a number of years.

What happened

According to Pearson, the student data affected was limited to students’ first name, last name and - in some cases - date of birth. No test scores, performance data or other identifying student information was part of the data incident. The AIMSweb 1.0 platform does not contain Social Security numbers or student addresses.


What you can do

At this time, there is no evidence that the student data has been used. However, as a precaution, Pearson is offering free credit monitoring for one year to families who may have been affected by the data breach.


Pearson provided the following information about enrolling in credit monitoring:

  • If you are redeeming this for a minor, provide your minor’s information when prompted.


District 41 takes security of all student data very seriously. Pearson Clinical Assessment has worked with cybersecurity experts to evaluate the incident and assured us that changes have been implemented to prevent this from happening again with their product.
