We have designed a law enforcement pre-employment polygraph booklet that has become the
standard in the State of Washington. Our basic booklet meets all current requirements of the federal Americans with Disability
Act. It contains approximately 250 questions to help you judge a candidate's suitability to become a police officer.
Specific areas of concern are general background, driving record, criminal history, financial history, military history, drug
use history, employment history, undetected crimes, and sexual history. Starting with this basic booklet, you are allowed
to make any deletions or additions to "tailor make" the booklet to fit your particular departments needs.
Contact us and we will send you a copy of the booklet for your review.
