6+ Polygraph Test Q&As: Police Hiring Tips

A pre-employment screening tool utilized by law enforcement agencies often involves a psychophysiological detection of deception examination. This examination includes inquiries designed to assess truthfulness and suitability for a career in policing. The content of these inquiries can be broadly categorized into relevant, irrelevant, and control questions. Relevant questions directly address potential disqualifying behaviors or past conduct that could compromise integrity. Irrelevant questions are neutral and serve to establish a baseline physiological response. Control questions are designed to evoke a deceptive response, providing a comparative standard.

The use of this investigative method aims to enhance the selection process by identifying candidates who may have a history of criminal activity, substance abuse, or other behaviors that could pose a risk to the agency and the public. The historical context reveals its implementation as a mechanism to improve the quality and integrity of law enforcement personnel, contributing to greater public trust and accountability. It seeks to weed out those who might be susceptible to corruption or abuse of power.

Prep: What is Asked on a Police Polygraph Test? Guide

The queries posed during a law enforcement polygraph examination are designed to assess the examinee’s physiological responses to specific inquiries. These questions typically fall into three categories: irrelevant, relevant, and control. Irrelevant questions establish a baseline of normal responses. Relevant questions directly address the matter under investigation. Control questions are designed to evoke a physiological response, serving as a comparison against the responses to relevant questions. For instance, in a theft investigation, an irrelevant question might be “Is your name [examinee’s name]?” A relevant question could be “Did you steal the money?” A control question might be “Before the age of [examinee’s age], did you ever take something that did not belong to you?”

The significance of the questioning lies in its role within the broader investigative process. The results provide investigators with additional data points to consider when evaluating a suspect’s potential involvement in a crime. Historically, these examinations have been used to narrow the scope of investigations, corroborate or challenge existing evidence, and, in some jurisdictions, as a condition of employment for law enforcement personnel. While not always admissible in court, the insights gained from these inquiries can influence the direction of an investigation and inform subsequent actions.
