Summary:
ZIP code 98589 has one middle school, Tenino Middle School, serving about 291 students in grades 6–8 in the Tenino area. The school is part of the Tenino School District, which ranks near the middle of Washington districts. Because there is only one middle school in the ZIP code, families cannot compare schools locally, so the most useful benchmarks are the school’s district, state, and year-to-year results.
Tenino Middle School has a mixed academic profile. Science is the strongest subject: 51.16% of students were proficient in 2025–2026, almost identical to the Washington rate of 50.95% and slightly above it. Eighth-grade science also exceeded the state result. English Language Arts proficiency was 38.29%, below the district rate of 43.06% and the state rate of 52.81%. ELA results were below state averages in every grade, although 7th grade was the school’s strongest ELA grade at 42.17%. Math is the clearest area for improvement, with only 25.28% of students proficient compared with 32.92% districtwide and 43.11% statewide. Eighth-grade math was especially concerning at 19.54%, nearly 19 percentage points below the state result.
Results declined modestly from the prior year in all three subjects: ELA fell 3.29 percentage points, math fell 2.28 points, and science fell 3.74 points. The school ranked in the 32nd percentile statewide in 2025–2026, down from the 37th percentile the year before. More than half of students, 52.58%, qualified for free or reduced-price lunch, an important context when considering student support needs. Overall, families can view science as a relative strength, while math—particularly 8th grade—and schoolwide ELA deserve the greatest attention. The school’s moderate 16.3-to-1 student-teacher ratio and reported spending of $18,842 per student provide additional context, but do not alone determine educational quality.
