Summary:
Zip code 98638, serving the rural Naselle area, has two public schools at the same 793 SR 4 campus: Naselle-Grays River Valley Elementary for grades K–5 and Naselle-Grays River Valley Junior Senior High Schools for grades 6–12, both operated by the Naselle-Grays River Valley School District.
The elementary school is the strongest current academic performer. In 2025–2026, 55.38% of students were proficient in English language arts, 64.62% in math, and 66.67% in science—above Washington averages in every subject. Math was especially strong, exceeding the state rate by about 21.5 percentage points. The school’s ranking also improved notably, rising from the 33rd percentile in 2023–2024 to the 72nd percentile in 2025–2026. With 127 students and a 14.7-to-1 student-teacher ratio, it offers a relatively small-school setting. However, 71.65% of students qualify for free or reduced-price lunch, indicating that many families may face economic challenges.
The junior-senior high school serves 189 students and has a higher 18.2-to-1 student-teacher ratio. Its English language arts proficiency was 55.91% and science proficiency was 55.56%, both slightly above state averages, but math proficiency was only 26.6%, well below the state’s 43.11%. All reported tested grades were below state math results, making secondary math the clearest area for improvement. The high school’s ranking nevertheless rose to the 77th percentile in its latest reported year, and science improved substantially from the prior year. Overall, families will find a small district with improving rankings, strong elementary performance, and generally solid secondary ELA and science results, but a significant math gap after students move beyond elementary school. Suppressed “—” results should be treated as unavailable, not as zero performance.
