LockDown Browser: Live Proctoring

The “Instructor Live Proctoring” option uses LockDown Browser (LDB) to prevent cheating on the computer itself, while the instructor watches students via video conferencing.

This method is only recommended for small class sizes where instructors can effectively observe and track students during the exam. 


  • Windows and MacOS.
  • An iPad does NOT allow you to run a video conferencing app and LDB at the same time. Similar results can be achieved if a second device for the video conferencing itself is used (and use Windows/MacOS computer for LDB).
  • Students should make sure they have checked and updated LDB to the latest version.
  • For more, please refer to 'Frequently Asked Questions' on Respondus: Instructor Live Proctoring.

    2. Remind students the video conferencing system will continue to run in the background, enabling you to see (and hear) them during the exam.
