El Salvador elects its head of state – the President of El Salvador – directly through a fixed-date general election whose winner is decided by absolute majority. If an absolute majority (50% + 1) is not achieved by any candidate in the first round of a presidential election, then a run-off pool election is conducted 30 days later between the two candidates who obtained the most votes in the first round. The presidential period is five years, and re-election is not permitted.
Salvadorans also elect a single-chamber, unicameral national legislature – the Legislative Assembly of El Salvador – of 84 members (deputies) elected by closed-list proportional representation for three-year terms, with the possibility of immediate re-election. Twenty of the 84 seats in the Legislative Assembly are elected on the basis of a single national constituency. The remaining 64 are elected in 14 multi-member constituencies (corresponding to the country's 14 departments) that range from 3-16 seats each according to department population size
