Post-Conviction Sex Offender Testing (PCSOT)
Post-conviction polygraph examinations are effective in assisting professionals who provide supervision to persons convicted of a sexual offense with risk-assessment, risk-management, and treatment-planning decisions. It is imperative that these professionals have confidence in polygraph results. Mr. Sitko utilizes the latest computerized polygraph equipment, Lafayette’s LX6000, and software together with both seat and foot countermeasures pads to ensure accurate results.
Mr. Sitko is certified by the American Polygraph Association to conduct Post-Conviction Sex Offender Testing and is current with all continuing education requirements to include advance countermeasure training. Mr. Sitko leverages his former colleagues and other respected polygraph examiners to conduct periodic quality control to ensure proper test question construction and examination procedures conform with best practices.
Decision makers need to be thoughtful about accepting the lowest cost polygraph examination. Inexperienced polygraph examiners may provide you with a low-cost examination but the results may not be worth the results.

Not all issues can be the basis of a polygraph examination. Only one issue can be explored per test and multiple issues will require multiple examinations.
