Background Investigations


Prince George's County requires a pre-employment background investigation for all public safety employees sworn and civilian. The background investigation process determines whether a candidate meets the standards and requirements to become a public safety employee. Public Safety Investigations manages the investigation process which includes verifying identity, education, employment history, criminal record, and credit history and will include interviews with family, friends, and relatives. It is the responsibility of the applicant to provide all necessary documents to PSI so the investigation process can begin. Failing to respond will delay the pre-employment investigation.

As part of the background investigation process for sworn positions you will be subjected to a truth verification examination, such as a polygraph examination or voice stress analysis, and a psychological evaluation. Other positions may require a psychological evaluation.
