Summary:
ZIP code 98937 has one middle school, Naches Valley Middle School in Naches, serving grades 5–8 and 427 students in the Naches Valley School District. Because it is the only local middle school, families cannot compare it with another school within the ZIP code and should consider its results against district and Washington state averages.
Naches Valley Middle School’s strongest area is English Language Arts, with 39.2% of students proficient, compared with 42.17% districtwide and 52.81% statewide. Seventh-grade ELA is a notable bright spot: 52.53% of students were proficient, nearly matching the state’s 53.23%. Math is the largest concern, with 25.46% proficient, below both the district’s 32.04% and the state’s 43.11%. Sixth-grade math was especially weak at 17%, while fifth-grade ELA also showed a substantial gap, at 32.29% compared with 53.87% statewide. Science proficiency was 34.46%, also below district and state results.
Parents may also want to note that proficiency declined from the prior year in ELA, math, and science, by roughly five percentage points in each subject. The school ranked in the 30th percentile statewide for 2025–2026 and received a one-star rating, although ranking pools change from year to year. About half of students qualified for free or reduced-price lunch, and the reported student-teacher ratio was 19.1 to 1. These figures provide useful context but do not explain individual student outcomes. Overall, the clearest priorities are sixth-grade math, fifth-grade ELA, schoolwide math improvement, and stronger science performance, while seventh-grade ELA demonstrates that the school has at least one area performing close to the state average.
