Class (Senate term)

Article I, section 3 of the Constitution requires the Senate to be divided into three classes for purposes of elections. Senators are elected to six-year terms, and every two years the members of one class-approximately one-third of the Senators-face election or reelection. Terms for Senators in Class I expire in 2013, Class II in 2015, and Class III in 2011.[1]
