How does the Safe Exam Browser work?

I want to make sure that students cannot browse the internet during the exam


Answer

Safe Exam Browser (SEB) is a customised web browser available for Windows (7, 8.1, 10, 11), macOS (starting with 10.7, recommended 10.11 or newer), and iOS (9.3.5 or newer). The application must be downloaded and installed on the device that the student uses to attempt the quiz. The software turns any computer temporarily into a secure workstation. It controls access to resources like system functions, other websites, and applications and prevents unauthorized resources from being used during an exam.

SEB is connected via the internet to a learning management system (LMS) or an e-assessment system. Moodle offers a quiz mode specifically compatible with SEB—no other Moodle activities can be administered through SEB, nor can the SEB be installed on the school's computers (at least, not without the authorisation of IT support, as it requires admin privileges). Therefore, SEB must be installed on the students' own devices.

SEB prevents students from accessing unauthorised resources through the following restrictions:

  • Students will only be able to attempt the quiz if they are using Safe Exam Browser.
  • The browser window will not have a URL or search field, and back/forward navigation and reload can be disabled.
  • Safe Exam Browser cannot be closed until the test is submitted.
  • Switching to other applications is disabled by default
  • Shortcut keys such as Win+Tab, Alt+Tab, Ctrl+Alt+Del, Alt+F4, Print Screen, and Cmd+Tab are disabled or cannot be used to close Safe Exam Browser or to switch to other user accounts on the computer. The possibility of taking screenshots is disabled.
  • The clipboard is cleared when starting and quitting Safe Exam Browser.
  • The browser context menu is disabled.
  • Spell checking and dictionary lookup are disabled but can optionally be allowed.

Some exceptions can be allowed by the instructors, although they might make the activity less safe.

Instructions on how to set up SEB are available on the Moodle QuickGuide for Faculty (link below)
