    I am the Quality Assurance Manager for the South Carolina Department of Probation, Parole and Pardon Services. Previously, I was the department's subject matter expert for risk assessments, during which time my department did and still does, use the COMPAS risk assessment.

    The main issue I see with this particular criticism, and many others, is the myopic view of the assessment. This assessment tool does more than simply provide a chance of re-arrest. It also provides risk levels for an array of criminogenic needs that can be informative when developing a supervision plan for a client under our supervision. It also provides important data for resource allocation through our department (we are a state department). For example, we are exploring ways to help clients afford their court ordered therapy by helping to pay for some of it. To ensure these resources are used by the clients that need it most, we rely on the risk level provided by the COMPAS assessment and the criminogenic need risk in particular to quickly locate those clients.

    Equivant actually provides sort of triage tool to alert staff of when a full assessment is required (the 137 question one, which only a minority of our clients require) which is 4 questions long and provides simply general risk of recidivism, should a department elect to use it. Many departments used a much smaller and quicker assessments before the 4th gen assessments like COMPAS became more mainstream to determine risk....
