What is a CBP polygraph?

A CBP polygraph is a polygraph (lie detector) examination administered as part of the U.S. Customs and Border Protection (CBP) hiring process. It is used to help determine if applicants for law enforcement positions are suitable for employment by assessing their honesty and integrity. The exam typically covers topics such as criminal history, drug use, and national security issues. Passing the polygraph is a mandatory requirement for most CBP law enforcement jobs.
