About Us

The Office of Justice Programs (OJP) Diagnostic Center is a resource designed to provide local leaders and law enforcement with customized assistance in addressing violent and other serious crimes.   By analyzing local data and providing tailored assistance, the Diagnostic Center helps communities invest in what works by turning to data-driven solutions to address serious public safety issues at the state, city, county and tribal levels. Diagnostic Center assistance is intended to build community capacity to use data to make short-and long-term evidence-based decisions about public safety challenges. Specifically, the Diagnostic Center works collaboratively with community leaders to understand the scope of their unique crime problems, provide analysis and recommendations for local consideration and implement community-elected corresponding data-driven strategies to improve public safety and advance the criminal justice field. These efforts ensure that limited local resources are invested wisely and communities reap better public safety outcomes. To learn more about the Diagnostic Center, click here.

The Diagnostic Center’s value lies in its ability to offer real-time suggestions for local leaders to achieve change based on local priorities. To make real change in local communities, crime problems must often be solved through multi-disciplinary strategies that recognize how one factor contributes to changes in another factor. Diagnostic Center resources are applied in situations where local jurisdictions request collaboration with the Department to address emergent, chronic or complex public safety issues. The Diagnostic Center employs a three-phased process that engages multiple experts when helping communities address criminal justice and public safety issues. In using a data-driven approach, the Diagnostic Center partners with communities to (1) diagnose the issue and map it to customized solutions; (2) implement promising practices in criminal justice, juvenile justice and victim services; and (3) assess the impact of practices implemented during the engagement. The Diagnostic Center does not direct local actions, but supports local decision making by using local data to better understand the contributing factors and scope of the problem to be addressed.  In addition to providing customized technical assistance, the Diagnostic Center also provides communities with access to additional resources within the U.S. Department of Justice such as CrimeSolutions.gov.

Since its launch, the Diagnostic Center has engaged with communities across the United States to address public safety issues ranging from improving clearance rates on homicides to improving officer safety and wellness.  The “clients” of Diagnostic Center engagements are police chiefs, sheriffs, other law enforcement and justice system leaders, prosecutors and local elected leaders.
