Item compromise is a consistent threat to the validity of certification examinations due to prevalent piracy practices that include the regular theft and unauthorized release of individual items, entire item pools, and exam forms. It has been documented that item compromise is widespread within information technology certification exams in particular; live exam content and items are routinely being exposed on the Internet.
