Respondus LockDown Browser

Respondus LockDown BrowserRespondus 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 and Mac OS X 10.5+.) UofL student instructions and download.

Instructions for Students

The following instructions will show students how to download the UofL version of the Respondus LockDown Browser from the Blackboard Help pages.

(Instructors, please include this PDF in your course along with your intention to use LockDown Browser.)

If you have Lockdown Browser test and students are having trouble accessing the exam, please follow the instructions in the workaround below.

***Add an optional password to the exam via the optional password field in the LockDown Browser Dashboard tool.***

Adding this password seems to allow students to enter the exam. You will need to give the students the password you’ve set. You should NOT use the same internally set password that resides on the Blackboard test settings page. Once the password is set on the Lockdown Browser dashboard and saved, be sure to test it to ensure it works.
