AntiPolygraph.org has received information that the
relevant questions asked on the Los Angeles Police Department's pre-employment polygraph examination are very similar to these:
1) Have you stolen more than four hundred dollars in cash or property from an employer?
2) Are you withholding information regarding your illegal drug history?
3) Have you committed an undisclosed serious crime?
4) Based on your personal bias, have you ever committed a negative act against anyone?
5) During a domestic dispute, have you physically harmed a significant other?
For the most part, these are very obvious relevant questions. But note that #4 is vague enough that it might easily be confused for a probable-lie "control" question.
Commonly used "control" questions include:
1) Prior to your application, did you ever lie to someone in a position of authority?
2) Before this year, did you ever put false information on an official document?
3) Prior to this year, did you ever betray someone who trusted your word?
4) Before your LAPD application, did you ever do anything that would place your integrity into question?
5) Before this year, did you ever take credit for something you didn't do?
6) Prior to this year, did you ever deceive a family member?
Note that all of these "control" questions include a "time bar" placing the scope of the question before the current year or before the applicant's application for LAPD employment. This practice might be changed after this information is posted.
The procedure also includes announcements of the beginning and end of the "test," an irrelevant question such as, "Is your name ______?" and a sacrifice relevant question along the lines of, "Regarding your background package, do you intend to answer each of my questions truthfully?"
