Data Request Process

The California Department of Justice (CADOJ) provides data to various entities throughout the country to assist with research and program evaluations related to improving the criminal justice system and informing data-driven policy. The Department of Justice Research Center (DOJRC) oversees the release of all CADOJ data to ensure that the requesting agencies and qualified researchers only receive the data that is required for completing their projects or mandated reports. The DOJRC releases CADOJ data on a need to know right to know basis to ensure the protection of all individuals’ personal information.
