The president of Colombia is elected every four years by direct popular vote and cannot serve consecutive terms. The constitution requires the president to be a native-born Colombian over 55 years old, with a university degree and previous experience as a congressional member, cabinet member, governor, or government official. As chief of state, the president oversees the executive branch of government, including a 13-member cabinet, administrative agencies, decentralized agencies, and appoints the cabinet members, agency chiefs, governors, and territorial heads.
