The misuse of evaluation is discussed. Boundaries of misutilization are not well understood, and distinctions between misutilization and non-use or abuse are not clear. In general, the responsibility for evaluation misuse is with the user, while the responsibility for misevaluation is with the evaluator. A distinction is also needed between intentional and unintentional misuse. Misuse of evaluation may be further defined as misuse of commissioning the evaluation, misuse of the evaluation process, and misuse of the findings. A more precise definition will refine the nature of misutilization in order to estimate how often it occurs. (SLD)
