Background Investigations

California Government Code §1031 requires a pre-employment background investigation for law enforcement officers. The Background Investigation process determines whether a candidate meets the requirements to become a law enforcement officer. The Background Unit manages the investigation process which includes verifying identity, education, employment history, criminal record, credit history and will include interviews with family, friends and relatives. It is the responsibility of the applicant to provide all necessary documents to the Background Unit so the investigation process can begin. Incomplete background packets will delay the pre-employment investigation.
