This book 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, it provides applicable, step-by-step instruction on determining an initiative's necessity prior to its adoption, as well as how to accurately gauge its effectiveness during initial roll-out stages. The book gradually introduces basic data analysis procedures and statistical techniques, which, once mastered, can be used to prove or disprove a program's worth. Lastly, it outlines the types of stakeholders who should review evaluation results for quick action, as well as how to best structure reports to ensure their buy-in.
