Best Public Schools in Zip Code 98239

Zip code 98239 has four schools serving about 952 students from preschool through 12th grade: Coupeville Elementary School, Coupeville Middle School, Coupeville High School, and Coupeville Open Academy. All are part of the highly rated Coupeville School District, which ranks in the 91st percentile among Washington districts. The area offers a conventional elementary-to-high-school pathway along with a small alternative-style high school program.

Coupeville High School stands out overall, ranking in the 88th percentile statewide and reporting a 93% graduation rate, compared with 82.6% statewide. Its 2025–2026 proficiency was especially strong in English language arts at 77.63%, while math reached 48.68% after a major 20.35-point increase from the prior year. Coupeville Elementary School offers the broadest academic strength, exceeding state averages in English, math, and science. Its science proficiency was 69.23%, and upper-grade English results were particularly strong, rising from 46.67% in third grade to more than 72% in fourth and fifth grades.

Coupeville Middle School performs well in English and science, but math is the clearest area for improvement. Overall math proficiency was 40.79%, and eighth-grade math was 32.88%, below the state result. Science is a consistent strength across the district’s conventional schools, with all three exceeding the state average by at least 13 percentage points. The small Coupeville Open Academy has suppressed current test results, so its academic performance cannot be directly compared; its historical graduation and dropout figures should be interpreted cautiously because of its enrollment of only 46 students.
