A Chromebook extension for LockDown Browser is available for exams delivered in Canvas, Blackboard Learn, D2L Brightspace, Schoology and Moodle.  This solution is for student-owned and also managed devices.

The Server Profile Setting
The LockDown Browser for Chromebook setting is enabled by default for all Respondus Server profiles. This profile-level setting can be disabled, if desired, and doing so will prohibit Chromebooks from being used for any exam that requires LockDown Browser.
 
Once you enable LockDown Browser to be used for a quiz, the LockDown Browser for Chromebook quiz-level setting is also automatically enabled....just like how it's done with LockDown Browser for Windows and Mac.

Important: You must use the LockDown Browser Dashboard tool to enable the LockDown Browser setting for the quiz. Any other method is unsupported, and will result in errors occurring when students attempt the exam via their Chromebook.

Installing the Chromebook Extension
To install the new extension to a student-owned Chromebook, students will need to use the regular LockDown Browser installation link for your school (they will NOT be able to search for the app directly from the Chrome web store.)  The LockDown Browser installation link will direct students to the Chrome web store, at which point they should select “Add to Chrome” to install the LockDown Browser Extension.

Managed Chromebooks
With managed Chromebooks, students will need to have the necessary permissions to install Chrome extensions, or the extension will need to be pushed to their Chromebooks via the Google Admin Suite. Instructions on how to do this can be found by logging on to Respondus Admin Area, and downloading the administrator guide titled "Managed Chromebooks."
