For correctional programs and policies to enhance public safety, they must be implemented as designed and adhere to research on best practices. Effective implementation hinges on proper, systematic, and accurate data collection on processes and outcomes. In recognition of this, there has been an increasing emphasis on formalized data collection in criminal justice systems across the United States. Currently, little is known about how large- scale data collection initiatives are developed and the process and quality of their implementation. The purpose of this study is to evaluate the development and implementation of a new data collection and reporting policy for Ohio specialty courts. Using a mixed-method approach to examine a range of implementation indices, processes, and contextual factors, this study aims to fill an important gap in the feedback loop between research and practice, inform and improve implementation of future data collection initiatives, and facilitate improved quality assurance practices within specialty courts. This study has received funding from the University of Cincinnati College of Education, Criminal Justice, & Human Services; the University of Cincinnati School of Criminal Justice; the University of Cincinnati University Research Council; and the American Society of Criminology Division on Corrections and Sentencing.
