The mission of the Office of Justice Programs (OJP) is to increase public safety and improve the fair administration of justice through leadership and programs nationwide. In order to advance that mission, OJP launched the Diagnostic Center in spring 2012. The Diagnostic Center assists communities and community leaders in implementing data-driven strategies to improve public safety and criminal justice outcomes. The Diagnostic Center’s defining characteristic is its diagnostic approach of first assembling and then analyzing data from the community. This methodical diagnostic approach includes identifying stakeholders, gauging the scope of community challenges, recognizing trends, establishing baselines, and determining which data points can be moved by implementation of data-driven strategies. The Diagnostic Center promotes the integration and translation of data on what works into enduring criminal justice and public safety solutions.
