Summary:
ZIP code 98589 has one listed high school, Tenino High School, serving grades 9–12 in the Tenino area, with 383 students enrolled.
Tenino High School has several positive outcomes for families to consider. In 2024–2025, 90.3% of students graduated, compared with 82.6% statewide, and the dropout rate was 6.4%, below Washington’s 9.8%. The school’s graduation and dropout results matched those of the Tenino School District. Science is the school’s strongest academic subject: 55.56% of students were proficient in 2025–2026, exceeding both the district’s 54.44% and the state’s 50.95%. Science performance also improved slightly from the previous year. Nearly half of students qualify for free or reduced-price lunch, and the student-teacher ratio is 20.7 to 1, providing useful context for families evaluating the school’s results.
The main concern is math. Only 19.59% of students were proficient in math in 2025–2026, compared with 32.92% in the district and 43.11% statewide. English Language Arts was more mixed: proficiency fell from 66.99% in 2024–2025 to 50% in 2025–2026, leaving the school slightly below the state but above the district. Overall, the school combines strong graduation and student-retention outcomes with uneven academic achievement. Its statewide ranking was 217th of 396 schools, in the 45th percentile, down from the prior year but better than in 2023–2024. For parents, the most important takeaway is that Tenino High School appears strongest in helping students complete high school and in science, while math and the recent ELA decline deserve particular attention.
