Founded in 1976 as a nonprofit organization, the Police Executive Research Forum (PERF) is a police research organization and a provider of management services, technical assistance, and executive-level education to support law enforcement agencies. PERF helps improve the delivery of police services through the exercise of strong national leadership, public debate of police and criminal justice issues, and research and policy development.

The Crime and Justice Institute (CJI) bridges the gap between research and practice with data-driven solutions that drive bold, transformative improvements in criminal and juvenile justice systems. CJI works with local, state, tribal, and national criminal justice organizations, providing nonpartisan policy analysis, implementation consulting, capacity building assistance, and research services to advance evidence-based practices and create systems-level change.

Some of CJI’s major projects include:
