Technical Bulletin


Published: May 20, 2022

What is happening?

Versions recommended in this bulletin apply only for the duration of the 2021-2022 school year.

Some districts running TestNav on Chrome OS 96 and 97 recently reported that while attempting to access math equation items, students unexpectedly experienced either the TestNav page fading to white and then black, or TestNav freezing and exiting the student to the sign-in page. 

Upon investigation, Pearson discovered a bug in these Chrome OS versions and reported it to Google, and Google applied a patch only to Chrome OS 96 LTS (long-term support) to fix the issue. Google will not be updating Chrome OS 97.

What does this mean?

Students on devices running Chrome OS 96 and 97 might see an interruption in testing while navigating through the test.

To avoid issues, Pearson recommends updating:

  • Chrome OS 96 to Chrome OS 96 LTS.
  • Chrome OS 97 to Chrome OS 98 (at a minimum).

What do I need to do (and how do I do it)?

Before a testing session, update Chrome OS devices running versions 96 or 97 to at least version 96 LTS or 98 (at a minimum). Then, have students sign in to test.

If a student experiences this behavior while testing on Chrome OS 96 or 97:

  1. Shut down the device.
  2. Restart the device and update it to Chrome OS 96 LTS or 98 (at a minimum)
  3. Resume the student's test and have the student sign in again.
