Best Public Schools in Zip Code 99664

In zip code 99664, the Seward, Alaska area is served by three public schools — William H. Seward Elementary School, Seward Middle School, and Seward High School — which together form a complete PK–12 feeder system within the Kenai Peninsula Borough School District, enrolling about 482 students with no alternative schools in the area. The elementary school is the clear academic standout, posting the strongest local results across most subjects; for the 2025–2026 school year, 56.76% of its students were proficient in science, far above the district’s 43.93% and the state’s 37.81%, while ELA and math also beat or nearly matched district averages.

By contrast, Seward Middle School is the biggest concern. Only 16.30% of its students reached proficiency in math — less than half the district rate of 38.40% — and its ELA proficiency of 23.91% is well below district and state levels. The middle school’s state ranking has fallen from the 40th percentile in 2023–2024 to the 9th percentile in 2025–2026, a dramatic slide that places it in the bottom 10% of Alaska middle schools. For families, this suggests the transition into middle school is a critical academic breaking point, especially in math. Seward High School sits between the two: its overall scores look weaker than the district, but a closer look shows that 10th-grade science (42.42%) and 9th-grade math (21.43%) actually meet or exceed state averages, while 9th-grade ELA remains a clear weakness.

Looking across the pipeline, science is a consistent strength, starting with standout 5th-grade results at the elementary level. However, math proficiency collapses between elementary and middle school — from roughly 37% to 16% — and the high school’s on-time graduation rate of 82.6% means more than 1 in 6 students does not graduate in four years. Even the elementary school has an “invisible” challenge in 3rd grade, where math and ELA proficiency fall below state averages before jumping in 4th grade. With small enrollments — just 104 middle and 173 high school students — annual proficiency percentages can shift easily, but the consistent patterns across grades make these findings meaningful for parents to understand as they plan each stage of their child’s education.
