The John Jay Research & Evaluation Center (JohnJayREC) is an applied research organization and part of John Jay College of Criminal Justice in New York City. We provide members of the academic community with opportunities to respond to the research needs of justice practitioners in the city, New York State, and the nation. At any given time, the Center is working on several projects designed to discover, test, and improve programs and policies related to the justice system. In recent years, our work has taken us to California, Colorado, Illinois, Massachusetts, Michigan, Pennsylvania, and Tennessee among other states as well as Belize, Puerto Rico, and the United Kingdom. Staff members at JohnJayREC are currently collaborating with the Center for Court Innovation to evaluate the Cure Violence model of violence reduction. We are studying the Office of Juvenile Justice and Delinquency Prevention’s Community-Based Violence Prevention Demonstration Program (CBVP) and recently began projects funded by the Annie E. Casey Foundation and the City of New York. The Center operates under the supervision of John Jay College’s Office for the Advancement of Research (OAR).
