Its ELA result was well above the district average, and its statewide ranking improved from the 6th percentile three years ago to the 12th percentile most recently.

Kiona-Benton City Elementary is generally stable, with math as its strongest subject relative to the district: 18.15% of students were proficient, including 29.67% in third-grade math. The most urgent concern is Kiona-Benton City Middle School, where only 7.24% were proficient in math, 14.71% in ELA, and 18.92% in science. Its ranking was below the first percentile statewide. Parents may want to ask about middle-school math supports, elementary-to-middle transition planning, and interventions for struggling students. Across the district, all schools remain below state averages, although the high school’s ELA gains and the elementary school’s relative math strength offer encouraging starting points.
