Polygraph Examinations
The polygraph instrument is the most commonly used instrument for the detection of deception.
The Fredericksburg Police Department uses the polygraph as an investigative aid during criminal investigations as well as during the pre-employment examination of candidates seeking employment with this department.
Every polygraph examiner is a graduate of an accredited polygraph school, accepted by the Virginia Department of Professional and Occupational Regulations (D.P.O.R.), and receives certification by extensive testing and additional training under the direction of the D.P.O.R.
After receiving certification, polygraph operators must then be licensed by the Commonwealth of Virginia.
