Respondus LockDown Browser Student Quick Start Guide

LockDown Browser is a locked browser for taking tests in Blackboard Learn. It prevents you from printing, copying, going to another URL, or accessing other applications during a test. If a Blackboard test requires that LockDown Browser be used, you will not be able to take the test with a standard web browser.

LockDown Browser should only be used for taking Blackboard tests. It should not be used in other areas of Blackboard.


Koç University has a unique URL for the installer. LockDown Browser must be installed to each computer (Windows or Mac) being used to take a test.

  • This download link is unique for Koç University and can be used by students
  • Follow the onscreen instructions to install.


  • Close all programs, unless one is used to connect you to the Internet.
  • Locate the “LockDown Browser” shortcut on the desktop and double-click it (For Mac users, launch “LockDown Browser” from the Applications folder).
  • If prompted, either close a blocked program (e.g. screen capture, instant messaging) by choosing Yes. Or, close LockDown Browser and close the blocked program before restarting.
  • Log into Blackboard.
  • Navigate to the test within the course and select Begin Exam.
  • The test will then start (Note, once a test has been started with Respondus LockDown Browser, you cannot exit until the Submit button is clicked).
