The management process of arts and cultural sponsorship traditionally concludes with an evaluation of the sponsorship cooperation in order to determine its performance metrics and thus its success. This involves assessing not only the organizational process but also the impact and cost-effectiveness of the activities. The chapter presents various methods and instruments of performance evaluation, particularly for process, effectiveness, and efficiency control. In addition, the problems and limitations of performance evaluation in arts and cultural sponsorship are discussed. For practical application, a sample questionnaire is provided as a basis for implementing control within the framework of audience studies. Finally, award winners of successful arts and cultural sponsorships are mentioned.
