This paper deals with the challenges of a program evaluation in the educational institution ‚kindergarten‘, and discusses the following challenges for evaluators: (1) conducting an explication of aims, (2) developing a custom-made evaluation design, (3) developing a suitable evaluation tool, (4) reporting the evaluation results. We illustrate the methodical approach of a program evaluation on the basis of concrete examples and reflect it against the background of the standards for evaluation of the German Society for Evaluation (2002).
