Best High Schools in Zip Code 99664

Zip code 99664 in Seward, Alaska is served by a single public high school, Seward High School, which enrolls 173 students in grades 9–12 and is part of the Kenai Peninsula Borough School District. Given this small enrollment, families should expect year-to-year proficiency rates to be sensitive to the performance of individual student cohorts rather than broad institutional trends.

Because Seward High is the only high school in this zip code, parents evaluating it should focus on its subject-level strengths and weaknesses. Science is a clear relative strength: 10th-grade science proficiency was 42.42% in the 2025–2026 school year, which exceeds the Alaska state average of 33.03% and closely mirrors the district’s 44.39% figure. Ninth-grade math was also a bright spot, with 21.43% proficiency beating both the district average of 17.88% and the state average of 17.91%. English Language Arts is the primary concern, however, with just 21.43% of 9th graders proficient compared with roughly 33% in the district and 31% statewide—a gap of about ten percentage points. The school’s all-grade math results were volatile, falling to 15.79% in 2024–2025 before recovering in 2025–2026, so current 9th-grade math strength may or may not persist. Science proficiency held steady at 42.42% across both reporting years, which is a positive sign of consistency.

Seward High’s graduation rate was 82.6%, slightly below the district average of 85.0%, and its statewide ranking has fluctuated: it placed 30th out of 63 schools (52nd percentile) in 2023–2024, slipped to 41st out of 60 in 2024–2025, and recovered to 37th out of 62 in 2025–2026, which still places it in the lower half of Alaska high schools. With 26.01% of students eligible for free/reduced lunch and a student-teacher ratio of 19.2:1, the school does not reflect an unusually high-poverty profile, making the ELA proficiency gap more notable. Families should weigh Seward High’s relative scientific strength and improved 9th-grade math against its ELA challenges and modest graduation rate, while keeping in mind that small cohort sizes can inflate or deflate single-year numbers.
