The handbook proposes general criteria to assess program effectiveness and poses several questions to guide program managers in determining the extent to which their program is effective. Methods for translating general criteria into specific program evaluation elements are described, and program examples show how these elements can be used to measure program goal and objective attainment. The handbook emphasizes the need to focus on innovative programs related to drug control, violent crime, and criminal justice system improvement. In addition, the handbook stresses both process and impact evaluation techniques, develops program effectiveness criteria, and describes the steps involved in developing and implementing a standard program effectiveness model. A glossary is included, and appendixes contain examples of drug law enforcement and community policing program evaluations. References and tables
