Washington Revised Code Title 28A. Common School Provisions § 28A.343.300. Directors--Terms--Number

The governing board of a school district shall be known as the board of directors of the district.

Unless otherwise specifically provided, as in RCW 29A.04.340, each member of a board of directors shall be elected by ballot by the registered voters of the school district and shall hold office for a term of four years and until a successor is elected and qualified. Terms of school directors shall be staggered, and insofar as possible, not more than a majority of one shall be elected to full terms at any regular election. In case a member or members of a board of directors are to be elected to fill an unexpired term or terms, the ballot shall specify the term for which each such member is to be elected.

Except for a school district of the first class having within its boundaries a city with a population of four hundred thousand people or more which shall have a board of directors of seven members, the board of directors of every school district of the first class or school district of the second class shall consist of five members.
