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.
