Chrome Mobile Devices

This topic describes how to configure Chromebook devices for online testing.

Device

Disabling Auto Updates

A user may want to disable auto updates during the LEA’s or test site’s selected testing window to avoid unknown issues that may be introduced by future operating system updates (although versions of Chrome are presumed to be supported). For example, if CAI supports up to Chrome OS version 91, and version 91 is installed on students’ Chromebooks, a user can prevent auto updates to any later version. (Alternatively, a user can allow auto updates to a specific version supported by CAI; for details, refer to the next subtopic, Limiting Chrome OS Updates to a Specific Version for Managed Chrome Devices.)

To disable auto updates for Chrome OS:

  1. Display the Device Settings page by following the procedure in any of the topics on the Manage updates on Chrome OS devices web page. The steps in that procedure assume that the Chromebooks are managed through the admin console.
  2. From the Device updates list, select Block updates.
  3. Select [Save].

Limiting Updates to a Specific Version for Managed Chrome Devices

CAI has tested the operational software being used (such as the Test Administrator Interface) and the practice and training tests up to version 91 of the Chrome OS; a user may want to prevent a Chromebook from auto-updating beyond that version. (Alternatively, a user can disable auto updates entirely; for details, refer to the subtopic Installing the SecureTestBrowser Kiosk App on Managed Chromebooks.)

To limit Chrome OS updates to a specific version:

  1. Display the Device Settings page by following the procedure in any of the topics on the Manage updates on Chrome OS devices web page. The steps in that procedure assume that the Chromebooks are managed through the admin console.
  2. From the Device updates list, select Allow updates.
  3. From the Restrict Google Chrome version to at most list, select the required Chrome OS version.
  4. Select [Save ].

Secure Browser

This topic contains instructions for installing SecureTestBrowser, the secure browser app for Chrome OS, as a kiosk application.

Installation

Installing the SecureTestBrowser Kiosk App on Managed Chromebooks

These instructions are for installing the SecureTestBrowser secure browser as a kiosk app on domain-managed Chromebook devices. The steps in this procedure assume that the Chromebooks are already managed through the admin console.

Chromebooks manufactured in 2017 or later must have an Enterprise or Education license to run in kiosk mode, which is necessary to run the secure browser.

  1. Set up a free Google Apps for Education account and enroll all managed Chromebooks.
  2. As the Chromebook administrator, access the Sign in web page to log on to the Admin console.
  3. When the Google Admin console opens, select [Devices], which is indicated in figure 1.
