The Program in Criminal Justice Policy and Management (PCJ) is part of the Malcolm Wiener Center for Social Policy at Harvard Kennedy School. Founded in 1980, we are celebrating 40 years of research to promote sound policy and effective management in the administration of safety and justice. We do this through research, teaching, and by maintaining long-lasting partnerships with practitioners, community members, activists, and other scholars. We organize Executive Sessions—intensive conversations among leading practitioners and scholars in a specific field that span several years, punctuated by research, practical experimentation, and collaborative publications.
