Summary:
Zip code 98858, serving the Waterville area, has two public schools in the Waterville School District: Waterville Elementary for kindergarten through fifth grade and Waterville High School for sixth through twelfth grade, with 256 students combined.
The two schools have different academic profiles. Waterville High School is the stronger performer in English language arts, with 71.43% of students proficient in 2025–2026 compared with 50.88% at Waterville Elementary and 52.81% statewide. High school ELA also improved substantially from the previous year. The high school’s 85% graduation rate matches the district and is above the 82.6% state rate. Its strongest grade-level result was eighth-grade ELA, at 76.19%. Waterville Elementary had a bright spot in fourth-grade ELA, where 58.33% proficiency exceeded the state result.
Math is the clearest shared area for improvement. Proficiency was below the state average at both schools, and every reported elementary grade trailed its statewide math comparison. High school science was close to the state average, while elementary science fell sharply from 61.11% to 46.15% year over year. The schools are small, with about 127–129 students each, so results can change noticeably from one year to the next as student groups change; suppressed scores should be treated as unknown. Historical rankings also declined, especially at the high school, showing that strong ELA performance has not yet offset weaker math and science results. The district is ranked in the middle range statewide, making comparisons between these two schools particularly useful for understanding local strengths and needs.
