Background checks ensure that candidates meet the legal and ethical standards required to become a peace officer and do not have a criminal history that could compromise their duties.

Offenses such as felonies, domestic violence charges, DUIs, and drug-related crimes are typically reviewed to determine a candidate's suitability.

A criminal history may disqualify a candidate depending on the severity of the offenses, their relevance to the duties of a peace officer, and the laws of the jurisdiction.

Credit history is reviewed to assess a candidate’s financial responsibility, as poor financial management may indicate potential vulnerability to bribery or corruption.

A history of illegal drug use may disqualify a candidate, depending on the jurisdiction and the time elapsed since the last use.

Psychological evaluations assess whether a candidate is mentally and emotionally fit for the demanding and stressful work of a peace officer.

A history of domestic violence may disqualify a candidate, as peace officers must demonstrate a history of lawful behavior and emotional control.

Prior military service is considered because it may demonstrate leadership, discipline, and experience in high-pressure situations.

A criminal conviction, especially a felony, may disqualify a candidate from becoming a peace officer, though some jurisdictions may allow for exceptions based on time and circumstances.
