Locking down computers for examination

With a KTH Digicertus Exam, the computers are locked with Safe Exam Browser (SEB) in order to ensure that students do not have access to anything other than the examination material. This page describes the solution, how to find out which computer rooms can be used, and how you order lockdown for your examination.

How locking with Safe Exam Browser (SEB) works

When an examination is conducted with KTH Digicertus Exam, the, computers are automatically started with Safe Exam Browser (SEB). With SEB, students only get access to parts of Canvas. The following parts of Canvas can be accessed with the lock:

  • Assignments
  • Quiz
  • Möbius quizzes (embedded)
  • Modules and files and pages that are published in modules

These parts of Canvas can be accessed for all course rooms the student has access to. The web, other programs on the computer and possibilities for communication through Canvas cannot be used. It is only possible to have one window open in SEB, so if there should be something in Canvas that the student can still access, it takes many clicks to get between different pages. 

Restrict access to other parts of Canvas

Since students also have access to other course rooms, the lockdown may need to be supplemented so that they do not have access to course material, such as regular course rooms (if an examination room is used) and previous course offerings. This is most easily done by editing the navigation menu in the room settings in each Canvas room so that the options are hidden. Read more about how the navigation menu works on the Course Settings page (heading "Navigation") . Remember to do this as late as possible before the examination, and please let the students know that they will not have access to the course material.

Using Möbius with SEB

You can only use embedded Möbius quizzes with SEB. To embed a Möbius quiz, the box "Load this tool in a new tab" should not be checked when Möbius is linked to the assignment.
