Pearson Data Security Incident - Frequently Asked Questions (FAQs)


Exactly what happened?

The Clark County School District (CCSD) became aware that one of its vendors, Pearson Clinical Assessment, had suffered a data security incident in an older version of their AIMSweb system, AIMSweb 1.0.

An unauthorized third party gained access to a set of data related to the AIMSweb 1.0 platform.

Whose information was accessed?

This incident may have impacted up to approximately 560,000 students enrolled at CCSD between 2008 and 2019, and a smaller number of staff members.

When did this happen?

Pearson believes this incident occurred on or around November 2018. The CCSD Technology Division became aware of this incident on Wednesday, July 31, 2019 and proactively reached out to Pearson immediately. Confirmation was received that our district was impacted on Thursday, August 1, 2019.

Why are we being notified now?

Although it is not clear whether your student’s directory information was affected by the security incident, or that any data was misused, out of an abundance of caution and in order to ensure transparency to our families, CCSD issued the notification.

It is common for an incident like this to not be discovered for many months. Public disclosure may also be delayed while law enforcement conducts investigations into the incident.

What information was potentially accessed?

The student data that may have been affected by the security breach was limited to students’ first names, last names, and in some instances, dates of birth.

A smaller number of staff members’ names and email addresses were also exposed, but in most cases the contact information is outdated.

No other data was part of the security incident; it was limited only to the above mentioned directory information.

What should I do if my children were enrolled during the school years impacted by this event?

  • Every person must carefully consider their own course of action in all matters of privacy
