This is a great introduction to the process by which an organization can evaluate whether a program is evidence-based is explained. “Although this guide grows out of and is targeted to juvenile justice practitioners, it is generally applicable to programs in other social service fields as well. It also bears noting that the steps described here are neither simple nor easy. Nevertheless, they are worth undertaking—even if a program does not complete the entire process, any progress along the way is likely to be beneficial” (p. 3). This publication explains: what an outcome evaluation is; why you need an outcome evaluation; who to prepare for an outcome evaluation; conducting an outcome evaluation; process evaluation—step one—whether the program is true to its original plan, step 2—the elements of an outcome evaluation, and step 3—the next steps after an outcome evaluation; and what statistical significance means.
