Evaluation standards can be useful not only as a framework for the design but as an assessment of particular evaluations. They can also serve as indicators for the developmental stage of evaluation practice in different areas or countries. Until recently, there has not been any large-scale and comprehensive empirical investigation of knowledge and use of evaluation standards for Europe. This article discusses the results of one such study that used the Joint Committee Program Evaluation Standards. The study, which the authors undertook on behalf of the European Center for the Development of Vocational Training, is a Europe-wide empirical study on evaluation standards within the policy field of vocational training and education (VET) that includes reflections from the standpoint of users, evaluators, and researchers in the field of evaluation.
