Chromebooks and Chromebases

Use the latest version of the Chrome browser. Remember to disable pop-up blockers.

The SecureTestBrowser kiosk application must be installed on Google devices for students to access the secure browser. Students can no longer test on Chromebooks manufactured in 2017 or later without an Enterprise or Education license. Google no longer allows users without these licenses to set up kiosk mode, which is necessary to run the secure browser.

To launch these devices in kiosk mode, they must be configured to be managed through the school's Google Admin Console. Further details on how to do this can be found on the Google support page.

CAI only supports versions of Chrome OS™ released on the Google stable channel. For a full list of supported Chromebooks, see support.google.com/chrome/a/answer/6220366.

We recommend disabling auto-updates or limiting auto-updates to a version used successfully before testing begins. This will prevent updates that pose a potential risk to student testing. It's safer to wait until CAI reviews new versions and lists them as supported.

Auto-update settings are configured in the Google admin console.

Chrome OS includes a feature called tablet mode, which offers a touchscreen environment for supported Chromebooks and for Chrome OS tablets. CAI doesn't support the use of tablet mode for testing but does support touchscreen features on Chromebooks.
