AIMSweb Data Breach

One of our third-party vendors, Pearson Education, recently informed the District that, in mid-March 2019, they discovered a data breach of their AIMSweb platform that occurred in or around November 2018 (AIMSweb is an assessment tool that helps teachers identify students who need additional academic support). The District last used AIMSweb in 2017.

Pearson has indicated that the specific data accessed for the District could potentially include:

  • Students’ first and last names
  • Students’ dates of birth
  • Teachers’ first and last names
  • Teachers’ Clayton email addresses


Pearson has indicated that no grade or assessment information was affected by this incident. It also did not involve Social Security numbers, credit card data, or other financial information, as AIMSweb does not store that type of information.

Pearson has informed the Ddistrict that they have completed a thorough investigation as to how and when the incident occurred and have taken appropriate steps to prevent such access from reoccurring.

You can read Pearson’s official communication about that incident here. While they do not have any evidence that any information has been misused, Pearson is providing affected individuals with the option to enroll in a complimentary one-year membership in Experian’s® IdentityWorksSM. Use this link for additional information on how to enroll in IdentityWorks.

The District takes data security very seriously and has communicated via email with those families and staff members impacted by this incident. If we receive any additional information from Pearson, we will provide that to you as well. If you have any questions about this incident, please feel free to contact Jeff Puls, the District's chief technology officer.
