Summary:
Tenino High School is the only high school in Tenino School District, serving grades 9–12 and 383 students in the Tenino, Washington area. The school has a 20.7-to-1 student–teacher ratio, and 45.43% of students qualify for free or reduced-price lunch. Because it is the district’s only high school, its graduation, assessment, and other high-school results represent the district’s overall high-school profile.
For parents, the strongest news is that Tenino High School has solid completion outcomes. Its 2024–2025 graduation rate was 90.3%, matching the district and exceeding the Washington average of 82.6%. Its dropout rate was 6.4%, below the statewide 9.8% rate. Science is another relative strength: 55.56% of students were proficient in 2025–2026, slightly above the district and 4.61 percentage points above the state. English Language Arts proficiency was 50%, higher than the district’s 43.06%, though slightly below the state’s 52.81%.
The most important concern is math. Only 19.59% of students were proficient in 2025–2026, placing the school 13.33 percentage points below the district and 23.52 points below the state. Math also declined from 31.19% the previous year. ELA fell substantially as well, from 66.99% to 50%, while science improved modestly. The school’s ranking also moved from the 60th percentile in 2024–2025 to the 45th percentile in 2025–2026. Overall, the school appears effective at keeping students on track to graduate, but families should ask about math interventions, tutoring, course support, and how the school is addressing recent assessment declines.
