System Requirements to Take The Exam

Candidates should run the PSI Online Proctoring System Check to verify that their machine meets the technical requirements for taking a proctored exam.
The online proctored exam is taken on PSI proctoring platform "Bridge", using the PSI Secure Browser (a web browser created to guarantee a secure exam delivery over a virtual connection).
PSI Secure Browser Download is made available to candidates at Exam Launch Time.
Candidates should review the Bridge FAQ Information, published by PSI, to prepare for the Secure Browser installation and be aware of how to resolve issues with the Installation/download or launch of their exam:
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.

    • 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.
