There are dozens of risk assessment tools in use in local criminal justice systems around the country. Not all have a far reaching impact, such as those specialized to a specific risk like domestic violence or those assessing risk for a certain demographic like juvenile offenders. Tools that have the broadest impact and deployment, however, are ones that look at recidivism pretrial risk in adult populations.

Below, we highlight these specific tools in use in each state, and the criminal justice decisions point they influence. These findings are part of a broader research project examining how jurisdictions implement risk assessment tools, and how they determine they accurately work and are implemented as intended. The project also dives into how risk assessment tools generate their scores and the debate around whether these instrument exacerbate or mitigate bias in criminal justice decision making.
