Sommario/riassunto |

Practical Program Evaluation for Criminal Justice shows readers how to apply the principles of fiscal responsibility, accountability, and evidence-based practice to criminal justice reform plans. Unlike other policy-based texts, which tend to focus more on implementation than assessment, this book provides applicable, step-by-step instruction on determining an initiative's necessity prior to its adoption (reducing the risk of wasting resources), as well as how to accurately gauge its effectiveness during initial roll-out stages. The book gradually introduces basic data analysis procedures and |
