Quality Control Reviews

A Quality Control Review (QCR) is a critical independent review and assessment of PV examinations conducted by other Forensic Psychophysiology Experts. A Quality Control Review (QCR) is absolutely necessary in assessing the validity and reliability of the proferred PV examination prior to its submission to the Court and ensuing review by opposing counsel's expert. HNS POLYGRAPH has successfully documented grounds for argument in poorly conducted examinations.

 For more information about QCR's, and the examination/cross-examination of QCR experts plus model scripts, see the textbook "Examination and Cross-Examination of Experts in Forensic Psychophysiology Using The Polygraph" by James Allan Matte available at amazon.com and / or call HNS Polygraph.
