Software Requirements (2021-22 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.

Use only 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. 

For TestNav Apps (kiosk-mode available)

When necessary for some tests, TestNav apps can run in kiosk mode, which prevents students from accessing any other web pages or applications while testing.

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.
