Summary:
ZIP code 98565 contains one public high school, Napavine Junior Senior High School, a grades 7–12 school with 410 students in Napavine, Washington, part of Napavine School District. Because it serves both middle and high school grades, its all-grade test results blend 7th–12th grade performance, which is important context. The school reports a 19.1 student-teacher ratio, 41.71% free/reduced lunch, and $14,682 per-student spending.
Academically, the school shows a mixed picture. In 2025–2026 all-grade ELA was 53.47%, slightly above the state’s 52.81%, while all-grade math was 34.65% versus the state’s 43.11% and all-grade science was 48.2% versus 50.95%. Grade 8 was a clear strength: ELA 59.38% vs. 50.9%, math 43.75% vs. 38.8%, and science 50.79% vs. 48.78%. High-school grades were weaker: 10th grade math was 20.83% vs. 35.42%, 10th grade ELA was 55.56% vs. 64.41%, and 11th grade science was 46.05% vs. 48.78%. All-grade scores improved from 2024–2025 to 2025–2026: ELA +3.47 points, math +3.43 points, and science +5.55 points.
Completion outcomes are a bright spot: the graduation rate was 89.2% vs. Washington’s 82.6%, and the dropout rate was 5.3% vs. 9.8%. The school’s state rank moved from 38th percentile / 2 stars in 2023–2024 to 28th percentile / 1 star in 2024–2025, then to 41st percentile / 2 stars in 2025–2026. The district’s own rank is 96 of 238, 60th percentile, 3 stars, though district and school rankings are not directly equivalent. For parents, the main takeaway is that the school has strong graduation and dropout results, improving test scores, and solid middle-grade performance, but high-school math is the clearest concern — especially 10th grade math — with high-school ELA and science also needing attention.
