Best High Schools in Zip Code 98638

ZIP code 98638 has one high-school-level school, Naselle-Grays River Valley Junior Senior High Schools, serving grades 6–12 in a small, rural community. The school enrolls 189 students and is part of the Naselle-Grays River Valley School District. Because it is the only school of its type in the ZIP code, there are no local school-to-school comparisons; the most useful benchmarks are the district and Washington state. The school has an 18.2-to-1 student-teacher ratio, and 65.61% of students qualify for free or reduced-price meals, providing important context about the community it serves.

The school’s recent overall standing has improved. Its ranking rose from the 57th percentile in 2022–23 to the 77th percentile in 2024–25, when it received a four-star rating. Academically, English language arts is a relative strength: 55.91% of students were proficient in 2025–26, slightly above the district and about three points above the state. Science also showed substantial improvement, rising nearly 19 percentage points from the prior year to 55.56%, about five points above the state. Results vary by grade, however. Seventh-grade ELA was stronger than the state average, while sixth- and eighth-grade ELA results were lower. Families should also remember that many reported results combine middle- and high-school grades, and some high-school figures are suppressed because of small group sizes.

Math is the clearest area needing improvement. Only 26.6% of students were proficient in all-grades math in 2025–26, approximately 16.5 points below Washington and 15.5 points below the district. Math performance was below the state in every reported grade, with especially large gaps in sixth and eighth grade. The school’s latest available graduation rate is 83.3% from 2020–21, but current school-specific graduation and dropout figures were not provided, so those outcomes cannot be assessed today. Overall, parents will find a small school with improving statewide standing and strengths in ELA and recent science performance, alongside a significant need for sustained math support.
