Palau is a republic with a unitary state structure and a presidential form of government.
The 16 members of the House of Representatives are elected in single-member constituencies using a single-round, choose-one plurality system, aka first-past-the-post (FPTP).
The 15 members of the Senate are elected in a single nationwide constituency using a two-round plurality bloc voting system.
Presidential elections are held every 5 years in a classic two-round electoral system. The first round is held via a single-choice vote and the two candidates with the most votes advance to the second round if no one receives a majority (more than half of the valid votes, 50%+) in the first round.
