The Sentencing Project was founded in 1986 to provide defense lawyers with sentencing advocacy training and to reduce the reliance on incarceration. Since that time, The Sentencing Project has become a leader in the effort to bring national attention to disturbing trends and inequities in the criminal justice system with a successful formula that includes the publication of groundbreaking research, aggressive media campaigns and strategic advocacy for policy reform.
Each of these organizations has a history through the Jim Crow era and the gains of the late twentieth Century. Their current missions have broadened to include equity for all Americans, especially those who have been historically or are currently disenfranchised. The websites below are for the national organizations, though each has local or regional affiliates or chapters.
