Polygraph - There is no question that in recent years polygraph testing has gained increasingly widespread acceptance as a useful and reliable scientific tool. The science of polygraphs has progressed to a level of acceptance sufficient to allow the use of polygraph evidence in limited circumstances. The American Polygraph Association has been striving for three decades to improve the educational standards of its members, and the polygraph schools it accredits which, with some exceptions, currently require its applicants possess a minimum degree at the baccalaureate level.
