Software Requirements (2025-26 School Year)
Annually, Pearson updates support requirements based on the TestNav System Requirement Policy. Districts should use this policy to determine annual purchasing needs and prepare devices. See Upcoming Support Changes below this section for more info on coming changes.
| Tip |
|---|
Use supported operating systems as they appear on this page. Attempting to use an unsupported or beta version of an OS can result in TestNav error, as well as security issues during high-stakes tests. Pearson tests all beta and newly released OS versions to ensure functionality and security with TestNav BEFORE support is added in the tables below. We understand many of our customers are automatically downloading Chrome OS versions as soon as they become available. Due to Chrome OS frequent release cycles, Pearson continually tests beta versions of Chrome OS to efficiently add support. Any concerns with early testing will be communicated via a Technical Bulletin. We do not recommend betas to be used for interim or summative testing. See Beta Testing In-Progress section below for betas currently being tested. |

Upcoming Support Changes
Pearson aligns support requirements with changing technologies. See the TestNav System Requirement Policy for details.
When operating system updates are released, Pearson first tests a beta version and reports bugs to developers. When the final version is publicly released, Pearson also tests this version to ensure TestNav compatibility before supporting it. When hardware or software deprecates, Pearson drops support for it.
Pearson pushes major TestNav upgrades twice a year—in summer and in winter. See TestNav App Updates for more information.
