System Requirements to take the exam

The online proctored exam is taken on PSI's 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:

  • 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
