An explanation of (P), (T), and (E) appears below. Several strategies have substrategies with different ratings. Types of Strategies The strategies in this guide were identified from a number of sources, including recent literature, contact with state and local agencies throughout the United States, and federal programs. Some of the strategies are widely used, while a few have been subjected to only a limited number of trial applications. Some strategies have been subjected to well-designed evaluations to prove their effectiveness, while other strategies, including some that are widely used, have not been thoroughly evaluated. The implication of the widely varying experience with these strategies, as well as the range of knowledge about their effectiveness, is that the reader should be prepared to exercise caution in many cases before adopting a particular strategy for implementation. To help the reader, the strategies have been classified into three types, each identified by letter symbol throughout the guide: Proven (P)--Those strategies that have been used in one or more locations and for which properly designed evaluations have been conducted that show the strategies to be effective. These strategies may be employed with a good degree of confidence, but with the understanding that any application can lead to results that vary significantly from those found in previous experience. The attributes of the strategies that are provided will help the user make judgments about which strategies may be the most appropriate for their particular situation(s). Tried (T)--Those strategies that have been implemented in a number of locations, and may even be accepted as standards or standard approaches, but for which there have been found no valid evaluations. These strategies, while in frequent or even general use, V-3
