ABSTRACT
The goal of this book is not just to provide information on crime prevention programs and initiatives. Instead, the intent is to offer insight into what works in crime prevention. To accomplish that task, it is necessary to evaluate prevention programs and efforts. Because this text is a survey of the prevention fi eld,
it relies on evaluations conducted by other researchers. At fi rst glance, it may seem that reporting on evaluations that have already been conducted would be easy and straightforward. Unfortunately, a good deal of debate has occurred over what constitutes “good” evaluation (see Holcomb & Lab, 2003).
