In 2008, The Urban Insitute surveyed 751 parole offices in 40 states and recently published its findings on parole practices around the U.S. in its paper, An Evolving Field: Findings from the 2008 Parole Practices Survey. What the study determines is that best practices, including tailoring the conditions of supervision, implementing immediate graduated responses to parole violations, and developing supervision plans that balance surveillance and treatment, are beginning to take root in parole offices across the country.
