What is a full scope polygraph?

A Full Scope Polygraph is a type of security screening used primarily by U.S. government agencies, especially those involved in national security or intelligence. It is the most comprehensive form of polygraph examination, covering both counterintelligence and lifestyle questions. This means the test addresses topics such as espionage, sabotage, unauthorized information disclosure, drug use, and personal conduct. Individuals required to take a Full Scope Polygraph are typically being considered for positions with access to highly sensitive or classified information. Passing this examination is often a prerequisite for obtaining certain security clearances.
