Washington

Washington State Science Olympiad has grown more competitive over the years, with a number of new schools and teams each season. It has grown from having only three regional tournaments to having five regional tournaments. Washington's regional competitions include the Northwest Region (Bothell High School for Division B, University of Washington for Division C), the Southwest Region (Clark College), the Eastern Region (Spokane Falls Community College), and the South Central Region (Yakima Valley Community College, Division B only).

In recent years, the state tournament has been held at either Clark College, Highline College, or Eastern Washington University (switching from Eastern Washington to Western Washington each year).
