How reliable is Polygraph Testing?
The polygraph is highly reliable, provided the person using it is properly trained and their technique is validated. The American Polygraph Association (APA) has conducted studies which show the reliability of the tests to be as high as 98%.
The critical issue is that the examiner has graduated from an APA training school, that they are experienced, have undergone continual professional development, and that their findings are quality controlled by a qualified instructor. Engaging the services of Polygraph International UK gives you that confidence and peace of mind.
Our examiners provide "mother tongue" tests in languages including Arabic, Bulgarian, English, French, and Spanish. Polygraph International UK also have extensive experience of working in partnership with interpreters to provide examinations in most languages.
