What strategies can be effective in reducing crime and disorder in policing? The Evidence-Based Policing Matrix is a research-to-practice translation tool that organizes moderate to very rigorous evaluations of police interventions visually, allowing agencies and researchers to view the field of research in this area. The Matrix is updated with all qualifying studies each year.
