Schools in Zip Code 98953

Schools in ZIP code 98953 serve about 1,330 students from prekindergarten through 12th grade across four schools in the Zillah area: Hilton Elementary School, Zillah Intermediate School, Zillah Middle School, and Zillah High School. All are part of the Zillah School District, which serves as a complete local PK–12 pathway. The high school is the largest school, with 455 students, while the intermediate school has 270 students.

For academic performance, Zillah Intermediate School stands out overall, especially in math. Its 2025–2026 math proficiency was 55.04%, compared with 35.23% at Zillah Middle School and 22.88% at Zillah High School. Intermediate students performed particularly well in third grade, although results declined by fifth grade. Middle school achievement remains below state averages, but its statewide ranking improved steadily over three years, and performance generally increased from sixth to eighth grade. Hilton Elementary has enrollment and staffing information available, but the supplied data does not include test scores or rankings, so its academic performance cannot be fairly compared.

Zillah High School has the district’s strongest reported completion outcome: a 94% graduation rate, well above the 82.6% state rate. Its English language arts and science results are near the state level, but math is a significant concern. Across the district, roughly two-thirds of students receive free or reduced-price lunch, while per-student spending is similar across schools at about $16,000. For parents comparing schools, the key pattern is strong graduation performance and promising elementary math results, alongside a need to improve math achievement and maintain skills as students move from elementary into middle and high school.
