How is the exam proctored?

The certification exam is proctored remotely via streaming audio, video, and screen sharing feeds. The screensharing feed allows proctors to view candidates' desktops (including all monitors). The audio, video, and screen sharing feeds will be stored for a limited period of time in the event that there is a subsequent need for review.

The main function of the proctors during the exam is to facilitate the check-in process and to monitor the session. They do not, nor are they expected to, have the technical expertise to weigh in or provide insight on the exam servers or exam content. Proctoring for Linux Foundation Exams is explained here.

If you’re interested in taking an online proctored exam through PSI and want a better understanding of what to expect before registering, watch the PSI Online Proctoring Experience video.

Candidates must provide their own computer with:

  • Supported OS: Please review the System Requirements, published by PSI, in particular the supported Operating System Information.

  • All browsers are supported, however PSI highly recommends using the latest version of Google Chrome for the best exam scheduling experience, and because the secure browser is Chrome-based and will give a more accurate experience.

  • One active monitor (either built in or external) (NOTE: Dual Monitors are NOT supported)

  • Reliable internet access

    • Ensure others on the same internet connection are not performing activities that use excessive bandwidth (i.e. holding conference calls, streaming content, gaming, etc.)

    • A wired connection is often more stable and robust than a wireless connection

    • Turn off bandwidth-intensive services (e.g. file sync, dropbox, BitTorrent)

  • Microphone

    • Mac users may need to allow the PSI Secure Browser within their 'System Preferences: Security & Privacy: Privacy' settings for Microphone, Camera, Automation and Input Monitoring.

    • Please check to make sure it is working before you start your exam session.

  • Webcam

    • Ensure the webcam is capable of being moved as you will have to pan your surroundings to check for potential violations of exam policy.

    • If you will be testing from an employer-provide ISP or will use an employer provided machine, please ensure that streaming will be allowed using WebRTC.

  • To ensure a smooth exam experience, we recommend using personal devices without stringent security features, and on which you have the privileges needed to install applications and to end system process' and services.

  • We strongly advise test takers to avoid using work-provided devices for their exams, as this practice can result in technical challenges. Although it is sometimes possible to initiate and access the exam on such devices, work devices often come with security features and work-related applications that can disrupt the exam software, causing technical complications.

Candidates are not allowed to have other applications or browser windows running except the one on which the Exam is being shown.

Please review the PSI Bridge Platform: System Requirements to ensure your machine will meet the requirements of our online proctor.
