National Institute of Justice (NIJ) supports basic and applied research into criminal justice issues. Innovative approaches to controlling criminal behavior and improving law enforcement and criminal justice are tested and evaluated. Research results are disseminated through a wide variety of mechanisms including the quarterly "NIJ Reports" and a Research in Brief series designed for policy makers and criminal justice professionals. The Institute maintains a national and international clearinghouse on criminal justice issues. Its services are available to policymakers, criminal justice professionals, and the general public.
