Respondus and Proctorio

Respondus LockDown Browser® is a custom browser that locks down the testing environment within Blackboard. When students use 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. Available for Windows, Mac and iOS (Not for Chromebooks and other devices).

Your instructor may require the use of Respondus for your class. In order for Respondus to work, you need to do these three things:
