I get asked the following questions all the time from people that are making initial inquiries about polygraph testing. These questions are very important to know an accurate answer to. The first question is about the accuracy of polygraph testing.
1. HOW ACCURATE IS THE POLYGRAPH?
According to the American Polygraph Association, over 250 studies have been conducted on the accuracy of polygraph testing during the past 25 years, and it is estimated that the accuracy of decisions is generally in the range of 85-95% for specific issue investigations. Some of the most frequent errors may be caused by lack of training, non-functioning equipment, failure to properly prepare the examinee for the examination, poorly worded test questions, failure to assess the examinee’s emotional and physical condition, improper use of testing techniques, a lack of quality control review, and misreadings of the physiological data on the polygraph charts.
2. HOW MUCH DOES A POLYGRAPH TEST COST?
Fees for polygraph services usually depend upon the complexity and type of polygraph test to be conducted, and the average polygraph test will take between 3-4 hours and will include a detailed pre-test interview, collection of charts whereby the examiner will administer several polygraph charts, and an analysis of the polygraph charts. If you select a polygraph examiner solely based on rates, you should understand that shortcuts in time and service may lead to errors and future legal problems. The cost of a polygraph exam will vary, but an average will cost $500-$1000. If you would like to get an accurate quote for a polygraph test please feel free to call Dan Seiler at 301-991-4381
