Statewide Evaluation of Missouri’s 4-Track Drug Court Initiative

Status: current


Project Purpose: NPC is collaborating with the Missouri Office of State Courts Administrator to conduct process, outcome and cost studies of several courts implementing innovative 4-track drug court programs to better tailor services and supervision to the risks and needs of participants. In addition, NPC is developing a manual that the State can use with other jurisdictions as they move to implement similar initiatives.

Project Design: This project includes process, outcome, and cost studies. The process study includes an assessment of best practices and document review. The outcome and cost studies include data systems assessment, database design, and quantitative analyses of multiple agency data sets.
