Respondus LockDown Browser Help

Respondus Logo

Respondus LockDown Browser™ is a custom browser that locks down the testing environment within Blackboard. When students use Respondus LockDown Browser they are unable to print, copy, go to another URL, or access other applications. When an assessment is started, students are locked into it until they submit it for grading. (Supports Windows, Mac OS X 10.13to 13.0+, iOS 11.0+ iPad only and ChromeOS "Stable" channel.)


Lockdown Browser/Monitor is not compatible with Pixelbook laptops and will not install or run.
