Summary:
ZIP code 98568 contains one elementary school, Oakville Elementary, a K–6 school in Oakville, WA, serving 157 students in Oakville School District. Because it is the only elementary option in this area, this profile focuses on that school. Two caveats matter for parents: a “—” means the state suppressed the value to protect student privacy, so it is unknown rather than zero, and the school’s small enrollment can make year-to-year and grade-level percentages swing widely.
Statewide, Oakville Elementary has ranked consistently low: in 2025–2026 it was 980 of 1,138 schools, the 14th percentile, with 1 star; in 2024–2025 it was 966 of 1,160, the 17th percentile, 1 star; and in 2023–2024 it was 992 of 1,168, the 15th percentile, 1 star. The district, Oakville School District, is ranked 220 of 238, the 8th percentile, with 0 stars. For 2025–2026, all-grades proficiency was 24.14% in English language arts, 12.07% in math, and 50% in science. State rates were 52.81%, 43.11%, and 50.95%, respectively, so science nearly matched the state while math was about 31 points lower and ELA about 29 points lower. The school also reports 66.88% free/reduced-price lunch eligibility, $21,497 per-student spending, and a 15:1 student-teacher ratio.
The biggest academic concern is math: proficiency fell from 32.2% in 2024–2025 to 12.07% in 2025–2026, and 4th- and 5th-grade math were 17.65% and 13.64%. Science improved from 22.73% to 50%, likely reflecting a different 5th-grade cohort, so it is a promising one-year result rather than a settled trend. ELA declined from 32.76% to 24.14%; 4th-grade ELA was 29.41% and 5th-grade ELA 36.36%. Third-grade ELA and math were suppressed, so they cannot be evaluated. Overall, Oakville Elementary remains a low-ranked, high-need school with a notable science bright spot in 2025–2026, but math and ELA results well below state averages.
