Consent note – Assessments at Stage 1 and 2
Your assessments will be virtually proctored to validate test-taker identity. Where you provide your consent, the camera on your device will be activated to take regular photos throughout the course of the assessment to check that the face in every photo is the same.
Your device’s microphone is also accessed to detect the presence and duration of audio, possibly indicative of a conversation. Therefore, we advise you undertake your assessments in clear, direct view of your device’s camera, avoid covering your face with objects (e.g. hands or clothing), and limit detectable noise (e.g. speaking out loud).
