Respondus Lockdown Browser for Instructors

You can require students to take your Carmen quizzes with the Respondus LockDown Browser to create a more secure testing environment. The LockDown Browser is not intended to replace other browsers for regular Carmen use.

The LockDown Browser can be used in a lab or classroom equipped with computers or by students using their own laptops. The LockDown Browser is available in many university labs. Both Windows and Mac versions of the LockDown Browser are available for downloading. We do not recommend that students be asked to use LockDown Browser when they are taking online quizzes outside of a proctored situation.  

When students take your Carmen quizzes and exams with the LockDown Browser, they will be unable to:

  • Print or copy

  • Take screenshots of questions

  • Type in another URL (web address)

  • Access other applications (such as chat tools or another browser)


Although LockDown Browser provides enhanced security for quizzes and tests, this is true mainly when the quiz is taken in a computer lab or classroom. LockDown Browser will not catch students using multiple computers. Additionally, when used on an unstable wireless connection, LockDown may cause the students' computers to freeze when internet is lost.

Please consider carefully whether the benefits of using LockDown are worth the burden of it. This is true for both the students and instructors. Instructors will need to re-set quiz attempts after students lose connectivity or experience other unexpected problems and must abandon their quiz.

If students attempt to take a locked quiz on a computer without LockDown installed, the link to download LockDown will show after they click the link to start the quiz but before they actually enter the quiz. We recommend informing students ahead of time that the LockDown Browser will be required and that installing this browser won't modify their current version browsers in any way.

For individual installations, download the LockDown browser version for Ohio State using the following link: http://www.respondus.com/lockdown/information.pl?ID=462913331. Other links will only work for other institutions.

UX Tip

Beginning with LockDown Browser version, existing installs of LockDown Browser will NOT be auto-updated at this time. To obtain the latest version use the Check for Update feature or run the full installation program.

If you are a Computer Lab Manager and need to install the lab version of LockDown Browser on multiple computers, please contact carmen@osu.edu.

  • Quizzes are displayed full screen and cannot be minimized.

  • Copying and pasting anything to and from a quiz is prohibited.

  • Right-click menu options are disabled. Browser menu and toolbar options are disabled, except for Back, Forward, Refresh and Stop. Function keys are disabled.

  • The source code for the HTML page cannot be viewed.

  • More than 250 screen capture, messaging, screen-sharing, and network monitoring applications are blocked from running.

  • External sites may be included in your quiz without compromising the "locked" testing environment.

  • There is a button within the Browser that allows the insertion of special characters. These characters will be of most use to foreign language courses, though there are a few mathematical characters.

If you copy a LDB enabled quiz from a previous course OR the quiz is in a course that uses Blueprints, you must open the LockDown Browser dashboard for each new course.  Until the LDB Dashboard is opened for the copied/Blueprint course, the course is not recognized by the LDB servers and all the LDB specific settings (including the iPad option) will not be in effect.

Once you have enabled Respondus LockDown Browser for your course and required the use of LockDown Browser on a specific quiz, you have a number of settings to choose from which are discussed below. 

All advanced setting options

Lock students into the browser until exam is completed

Select this option to prevent students from exiting LockDown Browser before an exam is submitted for grading. A password can be entered to enable a proctor to close the browser during an exam.


We do not recommend using this option outside of a proctored environment.

Advanced settings: Lock students into the browser until exam is completed; optional password to close and exit early

If this option is left deselected, and if a student attempts to exit the browser during an exam, they will encounter the following prompt: 

Exit exam early warning message: Do NOT close the browser until the exam is complete. Your instructor will be notified if you exit the exam early.

If the student selects Close the Browser, the student is required to enter a reason for exiting the exam early.

Pop-up: Provide a reason why you are exiting the browser before the exam is completed.

The date and time the student exited the exam, as well as the reason provided by the student, is reported to the instructor from the LockDown Browser Dashboard.

To view the Early Exits:

From the drop-down menu next to the quiz title, select Review Early Exits.

From drop-down menu select "Review Early Exits"

Instructors can then view the Early Exit information including student name, date and time, and the student's reason for their Early Exit. 

Early exit details including name, date, and student's entered reason for early exit.

The Lock students into the browser until exam is completed setting doesn't apply to the LockDown Browser iPad app. Due to the design of Apple's Guided Access, a student cannot be prevented from exiting the exam by triple-clicking the HOME button and exiting Guided Access. If an instructor checks the setting, iPad users can still leave the exam by exiting Guided Access.  However, this exit will be shown in the LockDown Browser Dashboard with the following: "Student exited guided access during exam (iPad)".

Allow students to take this exam with an iPad (using the "LockDown Browser" app from the Apple App store
