The paragraph contains some mixed and repetitive information, along with brand names that seem out of context. Below is a refined and coherent translation into English:

It is about the incident. At present, approximately half of the states in the United States are certified by the FBI and submit monthly reports in the NIBRS (National Incident-Based Reporting System) format. In an effort to increase participation in NIBRS, the Bureau of Justice Statistics sponsored a project through the Police Executive Research Forum (PERF) in 2001. PERF designed an information resource manual to assist law enforcement agencies in implementing NIBRS-compatible reporting systems and has since held two annual conferences aimed at progressively implementing NIBRS across the United States.
The implementation of NIBRS aims to provide more detailed, incident-specific information about victims and crimes, leading to a more comprehensive understanding of juvenile violence. This additional information will serve as a valuable resource for teachers, parents, counselors, law enforcement officials, and school administrators. Nonetheless, the UCR (Uniform Crime Reporting) system remains limited in its informational capabilities when compared to data gathered by other national sources.
