Evaluation, Ahead of Print.
Policy evaluation literature has stressed the importance of independence of evaluations to guarantee objective evidence collection. The evaluator–client relationship is critical in this respect, since it contains inherent tensions due to the necessity for independent assessments alongside requirements for increased responsiveness to clients’ interests. Despite this distinct relationship, the client perspective has only recently received attention in research. This article presents findings from a survey among US evaluation clients and compares these to existing evidence from Switzerland. Unlike previous studies, we distinguish between constructive and destructive client influences. We show that professional experience and client familiarity with evaluation standards increase the likelihood of constructive influences aimed at improving evaluation results. Nevertheless, the findings indicate that dissatisfaction with an evaluation increases client’s attempts at influence that may be destructive. By discussing both motives behind influence and potential preventive measures, this article seeks to contribute to the increased social impact of policy evaluations.
