The Criminal History Access Act of 2025 aims to enhance the vetting process for law enforcement officers by granting state peace officer standards and training agencies access to federal criminal history records. These agencies are defined as state bodies with statutory authority to establish standards for the hiring, training, ethical conduct, and retention of law enforcement officers through certification or similar qualification processes. Specifically, the bill amends section 534(e) of title 28, United States Code, to include these agencies among those authorized to receive such sensitive information. This change will enable a more comprehensive background check for individuals seeking to become or remain law enforcement officers. Furthermore, the Act directs the Attorney General to amend relevant federal regulations within 180 days of enactment to ensure proper implementation of these new access provisions.
