What is LockDown Browser®?

LockDown Browser is a custom browser that locks down the testing environment within TCU Online. It is useful for securing online exams in classrooms or proctored environments.

Instructors have the option to enable LockDown Browser within the Quizzes tool in TCU Online. If enabled, students will be prompted to download, launch, and use the LockDown Browser in order to access the assessment. In order to use LockDown Browser, students must have the ability to install programs on the computer they will be using.

Note: Respondus products do not work on Chromebooks. Additionally, if students will use an iPad, this must be enabled in the Advanced Settings.

When enabled, LockDown Browser:

  • Displays assessments in full-screen mode; assessments cannot be minimized
  • Prevents access to other applications, including messaging, screen-sharing, virtual machines, and network-monitoring applications
  • Disables Print, Print Screen, and screen capture functions
  • Prevents copying and pasting anything to or from an assessment
  • Disables right-click menu options, function keys, keyboard shortcuts, and task switching
  • Prevents a student from exiting an assessment until it has been submitted for grading
  • Removes browser menu and toolbar options except for Back, Forward, Refresh, and Stop
  • Prevents students from using other browsers if an assessment has been set up for use with LockDown Browser

Instructor Tips and Best Practices

We recommend that instructors create an initial practice quiz that requires the use of LockDown Browser. This can be a quick, ungraded, 1-question quiz as the main purpose is to ensure that LockDown Browser is installed and functioning on each student’s device. This will allow you to work with your students to resolve any issues prior to the major assessment, and will therefore help ensure that your first major assessment using LockDown Browser runs smoothly.

If students encounter issues with LockDown Browser during the practice quiz, they can access the Help Center. With LockDown Browser open, they can select the Help Center button from the toolbar. From there, students can run the System & Network Check to make sure everything is working properly. If a problem is indicated, students can search for a solution in the Knowledge Base. Troubleshooting information can also be emailed to your institution’s help desk.

The practice quiz can remain available for the duration of the course, with unlimited attempts. This will allow students to check that LockDown Browser is correctly installed on multiple computers if needed.

Student Resources

LockDown Browser is a secure browser for use with the Quizzes tool in TCU Online. It prevents printing, copying, going to other URLs, or accessing other applications during an online assessment. If your instructor has enabled LockDown Browser for an assessment in TCU Online, you will not be able to access the assessment with a standard web browser. Instead you must download and install the free LockDown Browser software onto your computer in order to access and complete the assessment. A broadband connection is also required.
