Two types of laws govern the use of polygraphs in the employment setting: those aimed at restricting employers' use of such tests and those delineating the qualifications and conduct of polygraph examiners. This Article will survey and compare the present status of state laws relating to employer use of polygraph testing and the licensing of polygraph examiners. A brief background of the development of the polygraph is included, as well as a description of testing procedures, an assessment of test validity, and recommendations for a national uniform approach to polygraphs.
