The school’s statewide ranking improved from the previous year, moving from the 28th to the 31st percentile and returning to a two-star rating, but it remains in the lower third of ranked Washington schools. Because enrollment and grade cohorts are small, annual percentages can change noticeably based on the performance of a limited number of students.
