What is the Polygraph for Police Applicants?

Most  Law Enforcement Agencies will conduct a polygraph examination as part of their background check. The background check will include validating your educational and work experience, police record check, credit score and personal references.

An alternative method for testing truthfulness is the Computer Voice Stress Analysis (CVSA). In California, the CVSA is used by the California Highway Patrol and other agencies. You can learn more about the CVSA at  www.CHPtestPrep.com

A polygraph is a diagnostic instrument that records physiological changes in a person caused by stress, like answering questions that make or break your dream of becoming a police officer. It relies upon measuring the body's involuntary responses which occur when the subject is consciously being deceptive or untruthful.

A very good way to deal with the anxiety of taking the polygraph test is to know what to expect. This article covers the basics. Much more is presented in a full-length, on-line training course described below.

You will be asked about the following topics during a typical polygraph examination for entry level law enforcement positions.

  1. Theft of money or merchandise from employer, or by shoplifting.
  2. Illegal drug trafficking or dealing.
  3. Illegal drug or medication use, including steroids.
  4. Use of alcohol.
  5. Falsification or minimization in your requested information.
  6. Participation in any type of organized crime.
  7. Arrests for anything other than minor traffic violations.
  8. Commission of a crime which has not been detected.
  9. Concealment of anything in your background that would affect your chances for this position.
  10. Involvement in a physical fight with another person, including domestic violence.
  11. Use of excessive physical force against another person.
  12. Payment or receipt of any bribes.

Keep in mind, admitting to any of the above questions may disqualify you from consideration for the job. Exceptions would be minor offenses like shoplifted while a juvenile. Drug use also has certain time limits, such as, "if you haven't smoked marijuana in the last three years." Each police agency has their own policies, so check their minimum qualifications.

 

How To Prepare for The Police Polygraph

Preparation for the polygraph begins when you fill out your application. This critical point is covered in detail under Hiring Process on this site.

It is my suggestion that you deal with the above questions in a truthful and forthright manner on your application. Even though there are flaws in the polygraph process, giving honest answers to the questions is the best way to pass. This is not to say that in certain cases, despite giving truthful answers you are guaranteed to pass. You're not. It's not a perfect system. But if you are prepared for the exam by knowing what to expect and you are truthful, you can avoid triggering a "false failure."

Knowing what to expect and having confidence in your answers will help you eliminate the physiological changes which occur when being nervous. These physiological changes will lead to false positive readings and failure.

How do you prepare for the polygraph examination? Simply put, you need to relax and place your mind and body at ease. You need to be as "normal" as possible when taking the examination. Sgt. Godoy’s How to Pass the Polygraph will teach you how to achieve these results.

 

Most Important During the Polygraph

  1. Make no admissions to the relevant questions. If you're applying for a job and choose to make admissions regarding your background, the time to do it is when your application is submitted. From the moment you arrive for the polygraph, to the second you leave, make no additional admissions to the relevant questions. Red flags will go up when applicants wait until confronted with the polygraph to reveal the truth about their background. Admissions that may seem minor to you can be highlighted by your polygrapher.
  2. The only exceptions to this rule are that during the "pre-test" interview you may make minor admissions regarding the "control" questions only, such as stealing candy when you were a child, or lying to your parents, or taking pens home from work. But go no further.
  3. Prepare for the test and thoroughly familiarize yourself with the three types of polygraph questions (irrelevant, relevant, control/comparison) and be able to identify them. During the "pre-test" interview all questions will be read to you. Use this time to categorize each question in your mind.
  4. Familiarize yourself with the nonverbal body language that polygraphers associate with truth and deception. In addition to the charts, the polygrapher often factors in these nonverbal cues in his determination of truth or deception.
  5. Familiarize yourself with common interrogation tactics and use extreme caution, especially during any "post-test interview."
  6. Do not change your statements! Even the slightest attempt to clarify your response to a relevant question may be taken as an admission.
 

Reduce Your Risk of Failing the Polygraph

Make A Good First Impression

Your polygrapher's subjective opinion of you may influence the outcome of your polygraph interrogation. Look your best. Make sure you're clean shaven and have a conservative haircut. Dress professionally, polish your shoes. If you're a woman, dress conservatively.

Be friendly. Smile, but don't overdo it. Keep good eye contact with your polygrapher, but don't stare. Your polygrapher may interpret avoidance of eye contact as a sign of deception. Answer questions directly with confidence and without hesitation - but be natural.

Don't Be Late

If you're late you'll instantly make a bad impression. Your polygrapher may think being late is a subconscious attempt to avoid the polygraph - increasing his suspicion of you even before he asks his first question.

You'll Be Judged On Your Appearance And Demeanor

The moment you arrive for your polygraph, your polygrapher will be observing you. He will size you up based not only on what you say, but also on your appearance and demeanor. The interrogation room itself may be equipped with a two way mirror or a concealed video camera. It may not be easy but try to avoid looking nervous. You might consider bringing something to read or otherwise keep yourself productively occupied while waiting.

The Pre-Test Interview

Be polite and cordial. Answer your polygrapher's questions directly, but remember to make no damaging admissions. In response to the "control" questions, you may admit to some minor childhood misdeeds as mentioned before. But in response to relevant questions, you should make no admissions.

Keep your Answers Short

Answer any yes/no question with a simple "yes" or "no." Avoid replies such as, "yes, basically" or "not really." Such evasive answers will make you appear deceptive to your polygrapher. Don't be chatty or over friendly with your polygrapher. If you are overly talkative your polygrapher may interpret this as a sign of deception.
