Proctoring Services

For the purposes of this example the Proctoring Tool starts an audio/video conference with the candidate and asks them to present government issued id and the candidate offers their passport to the webcam. A live Proctor validates that the given and family names on the passport match those in the Start Proctoring message and that the passport photo is a good likeness of the person presenting the document! Satisfied that the candidate’s environment is secure the Proctoring Tool issues the Start Assessment message (click below)
