Questions are based on the information provided to the examiner.  Once an applicant has given information to the examiner, he or she will then evaluate the data and continue with the test question formulation. 

Some Polygraph Examiners are trained through the Federal Government.  Other Examiners are sponsored through the State, County or local Law Enforcement Agency they are employed by.  Others, mostly those with a law enforcement background, will apply and, if accepted, attend an Academy accredited by the American Polygraph Association.  

Anyone seeking the services of a Polygraph Examiner in California should inquire as to whether that person attended an Academy accredited, approved, or recognized by the American Polygraph Association.

“Polygraph” literally means “many writings.” Polygraph examiners use analog or computerized polygraph instruments to record the physiological data from at least three systems in the human body.  

A typical polygraph examination will include:
(1) A pre-test: the examiner will complete required paperwork, discuss the issue at hand with the examinee, and familiarize the examinee with the testing procedure.  All questions are reviewed with the examinee prior to testing.  There are no surprise or trick questions.  An examinee is fully aware of what questions will be asked of him/her prior to taking the test.  
(2) A chart collection phase: the examiner will administer and collect a number of polygraph charts.
(3) A test data analysis phase: the examiner will analyze the charts and render an opinion as to the truthfulness of the person taking the test. The examinee will have an opportunity to explain physiological responses in relation to one or more questions asked during the test.
