Arising from its participation in the Evidence-Based Decision Making Initiative, Rock County provides pretrial assessment and supervision services in the County. Pretrial services are aimed to maximize public safety and court appearance while maximizing pretrial release. Rock County uses the Public Safety Assessment (PSA), which uses static data factors to produce two risk scores about a defendant: one predicting the likelihood the individual will commit a new crime if released pending trial, and another predicting the likelihood of failure to return to a future hearing. Rock County believes utilizing data and research, as well as professional judgment based on comprehensive case-specific information will: promote fairness and equal treatment, increase public safety, reduce harm, and improve quality of life; and use resources effectively.
