Here you will find information about the members and structure of the review boards in previous membership periods. Review board members are elected every four years. Before each election, the Senate examines the structure of all review boards and subject areas and adapts it to recent developments in the research system. Election results are available as well as members' names for earlier membership periods as they stood at the end of each period. There may be differences between these two documents for the same period because elected members did not take up office or chose to leave a review board after serving for part of the period. In cases like these, in accordance with the election regulations the individual is succeeded by the person with the next highest number of votes.
