The highest EVS authority is the Council of Program Directors (formerly called the EVS Steering Committee). All daily responsibilities are delegated to an Executive Committee, which actually is in charge of the project. The Program Directors convene in principle yearly and their main task is to discuss the general outlines of the EVS project and to approve the final questionnaire and the survey methodology.
