ABSTRACT
The Control Question Test (CQT) is the most preferred technique in field polygraphy. Basically, in the CQT procedure, relevant questions which refer directly to the investigated crime are compared to control questions which introduces an issue of the same nature in a more general way. Eight experienced polygraph examiners interpreted, independently, the minor crimes sample records using the objective numerical scoring technique. Ten examiners did the same for the severe crimes sample records. While scoring the records, the examiners were blind to the guilt or innocence of the subject, to the frequency of deceptive and truthful records in the sample, and to the criminal case the record referred to. In order to find the interscorer agreement rate for the numerical scoring technique, the final scores obtained were condensed into 5 agreement regions according to the 5 main results of the field tests used for the polygraph examinations of the Israel police.
