Research and Evaluation

ILJ has always focused on research and evaluation that has practical value for the criminal justice field. We have completed more than 250 research projects. One key to our success is the excellent working relationships we maintain with our research sponsors—including many agencies of the U. S. Department of Justice—and with the criminal justice organizations that have joined us as partners and advisors.
