This digest describes some of the basic logic-of-evaluation skills and some of the basic methodological skills that need to be mastered in order to practice the art and science of evaluation. Some topics from the logic of evaluation that must be dealt with include understanding : (1) the differences and connections between evaluation and other…

Evaluators must use a flexible, open-minded approach oriented toward a holistic view of the implementation and operation of the program they are analyzing. The use of more than one methodology expands the potential findings and avoids the limitations of a unidimensional approach. (SLD)

This theme issue discusses the misuse of evaluation. The eight articles all discuss instances in which the evaluation process or evaluation findings were misused. Misuse is usually not the result of methodological issues but rather is an issue of human relations and sometimes of political pressure. (SLD)
