This question has gone unanswered for 4 days, which is a very long time on avvo.com. It may be that this question is hard to answer because very few lawyers are sitting there where the polygraph questions are asked. The second reason is probably that there is some variation to the questions that are asked. Anyway, the polygraph examiner is supposed to go over what questions will be asked before the polygraph. If you want to be as prepared as possible, stay calm, don't argue with the examiner, and tell the truth.

I assume you are asking about Washington County's official DV Deferred Sentencing Program - the one where the charges will be dismissed if you complete the requirements. To the best of my recollection, the polygraph comes after you have completed a certain amount of the DV classes. I know one area you will be asked about is whether you have had contact with the victim without the Court's permission.
