The examiner also care- fully reviews the agreed questions to be asked in relation to the specific issue of concern.  This procedure normally takes 45-90 mins to complete.
The agreed questions will be asked during this phase while the subject is attached to the polygraph sensors. Only the examiner and the client will be present while the test is being conducted.
