An important
decision...
Selecting
a qualified examiner can be a difficult process, considering
what is sometimes at stake. We understand the importance of this
decision, so we will never refer you to an inexperienced examiner
or one which uses a technique not validated by scientific research.
If done correctly, polygraph on average is 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 exam
The process is simple...
select a testing
location where you would like the exam and complete the registration
process. Once you decide to hire one of our examiners, we will
ask you for some information - needed to conduct the exam - and
for a deposit which will be applied towards the overall exam fee.
Within 1 to 2 business days the 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 exam by an experienced examiner in the geographic
area you selected. The examiner will work closely with the customer
to design the best 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 exam, upon request, a written
report will be provided to you at no charge.
