The purpose of this study is to link tasks performed by evaluators to the knowledge required to perform those tasks. It first describes the role of evaluation and the evaluation process in as general terms as possible. Second, it classifies the tasks identified in the process according to the phases of the evaluation process and the nature of the task roles within an evaluation. This gives two categories of tasks: technical and strategic. Those tasks are then assigned to modules of knowledge required to perform an evaluation. Third, a correlation table is developed showing the links between the various phases of the evaluation, the task categories, the tasks, and the knowledge modules. Lastly, a list of courses is suggested to form the nucleus of a study program in evaluation.
