LIE DETECTOR TESTING

Selecting a qualified examiner can be a difficult process, considering what is sometimes at stake. We understand the importance of this decision. We therefore, will never refer you to an inexperienced examiner, or one who uses a technique not validated by scientific research. If done correctly, polygraph testing is on average 90 to 95% accurate (click here to see the research). We offer only true polygraph services. Do not be fooled by offers of voice stress analysis (VSA), which the U.S. Government has determined to be unreliable

How to set up a polygraph test

The process is simple... select a lie detector testing location where you would like the polygraph test to take place and complete the registration process. Once you decide to hire one of our polygraph examiners, we will ask you for some information needed to conduct the exam. A deposit will be required which will be applied towards the overall exam fee. Within 1 to 2 business days, the polygraph examiner handling the selected area will contact you to schedule the exam at a date and time that is convenient for both of you. We guarantee you will receive a quality polygraph test by an experienced examiner in the geographic area you selected. The examiner will work closely with the customer to design the best polygraph test questions to resolve the issue under investigation. Keep in mind that a properly conducted exam may take 1½ to 3 hours to complete. Following the lie detector test, upon request, a written report will be provided to you at no charge.
