Hey Dat, I have taken several (for employment, I am on the right side of the law) The best thing to do is be as honest as possible. I know a few guys that run polygraph tests. The machine is calibrated at first allowing for your nervousness (expected) the machine will register that you may not be telling the truth when you become more "nervous" to a question. Like I say don't lie. You will have a discussion with the operator first and be asked a series of questions, then hooked up the the machine and asked a series of "yes" or "no" questions based on your long answers. Ex: "Besides what we have discussed, have you ever committed a criminal act"?
You will certainly be asked questions on your character, past drug use, criminal history (theft of any type the main concern for government employment) even your driving history AND yes GAMBLING! During the conversation phase, when asked if you gamble, you may say something like "I am not above betting a few bucks on football with my buddies, and have been in a few office pools and bought some Super Bowl squares". (This will not surprise the examiner, some of the best pick'em leagues are run by those in law enforcement) When the question is asked during the exam, you are not actually lying. This with lesson the flight of the little needle.
Relax and best of luck
FACTS for you:
A polygraph is an instrument that simultaneously records changes in physiological processes such as heartbeat, blood pressure, respiration and electrical resistance (galvanic skin response or GSR). The polygraph is used as a lie detector by police departments, the FBI, the CIA, federal and state governments, and numerous private agencies. The underlying theory of the polygraph is that when people lie they also get measurably nervous about lying. The heartbeat increases, blood pressure goes up, breathing rhythms change, perspiration increases, etc. A baseline for these physiological characteristics is established by asking the subject questions whose answers the investigator knows. Deviation from the baseline for truthfulness is taken as sign of lying.
There are three basic approaches to the polygraph test:
1. The Control Question Test (CQT). This test compares the physiological response to relevant questions about the crime with the response to questions relating to possible prior misdeeds. "This test is often used to determine whether certain criminal suspects should be prosecuted or classified as uninvolved in the crime" (American Psychological Association).
2. The Directed Lie Test (DLT). This test tries to detect lying by comparing physiological responses when the subject is told to deliberately lie to responses when they tell the truth.
3. The Guilty Knowledge Test (GKT). This test compares physiological responses to multiple-choice type questions about the crime, one choice of which contains information only the crime investigators and the criminal would know about.

Good luck on becoming a Firefighter Dat, and your more than welcome. I hope it helped some.

Originally posted by slappy's sonI also thought lie detector tests used straight YES / NO answers, and did not allow you to use explanations to sidestep the questions. If he asks "Do you gamble?"... you need to answer "YES".

No Dat, Thinking like that will make you fail.
Reveal what you need to in the discussion phase, when asked about it, you will not be lying with a straight "No" answer. The examiner will already know that you are a sports fan and sometimes wager with your "Buddies" on your favorite teams. The needle may move a little but not enough to fail you.
