Center for Police Research and Policy

Research and evidence helps to identify what's effective in order to improve how we do the things we do and to better understand why we do the things we do. IACP programmatic initiatives are backed by research and can be traced to evidence showing why a specific model or approach was used, how the project design impacts success of the program, and where the program will have the greatest effect.

About the Research Center

The International Association of Chiefs of Police (IACP)/University of Cincinnati (UC) Center for Police Research and Policy engages in rigorous research that has practical implications for the field and is intended to serve as a national model for the way law enforcement agencies and researchers work together to help protect communities, safeguard citizens’ rights, and ensure the fair treatment of all individuals.

There is currently a gap between research and practice that the IACP/UC Center for Police Research and Policy seeks to close. Often times existing research does not provide actionable recommendations that can be easily translated into practical policies and practices that could enhance policing. Moreover, academic researchers often do not have access to all the data that police departments have, yet this data is necessary to conduct rigorous and meaningful research on police practices. The goal of the IACP/UC Center for Police Research and Policy is to provide a path for law enforcement and researchers to work together on studies that will drive future practices and policies.

IACP's Research Advisory Committee

IACP's Research Advisory CommitteeBooks

In 2003, IACP established a committee with both researchers and practitioners to provide input, advice, and direction to the association, law enforcement practitioners, researchers, and the criminal justice system on all aspects of law enforcement policy research and evaluation. This esteemed group is a critical voice for both the academic and law enforcement worlds -- and works to ensure that needs are met on both sides.

Model Policy for Collaborative Research Partnerships

Research partnerships are a critical component for enhancing policing policies and strategies. Knowing how to partner, when to partner, and what to expect when partnering is important for both the agency involved, as well as the researcher. The Law Enforcement-Researcher Collaborative Partnerships Model Policy / Concepts and Issues Paper were designed to assist you in this process:
