Winlock School District

Winlock School District is a small district in the Winlock, Washington, community, with three schools serving students from prekindergarten through 12th grade and about 801 students overall. Winlock Miller Elementary serves grades PK–5, Winlock Middle School serves grades 6–8, and Winlock Senior High serves grades 9–12. The schools provide a close-knit, small-district setting, but their academic results differ considerably by grade level.

Winlock Senior High is the district’s strongest and most improved school. Its ranking rose from the 19th percentile in 2023–24 to the 57th percentile in 2025–26, and its 63.04% English language arts proficiency was above the statewide rate. Its math and science results were lower, at 30.43% and 46.67%, but still stronger than the district’s other schools. The school’s graduation rate was 82%, nearly matching both the district and state. Winlock Miller Elementary has its best relative performance in math, where 33.72% of students were proficient compared with 24.32% districtwide. Third-grade math was especially promising at 41.51%, although fifth-grade math and several ELA results remain areas for improvement.

Winlock Middle School is the most urgent academic concern. It ranked in the 6th percentile statewide in 2025–26, with proficiency of 26.14% in ELA, 11.84% in math, and 13.73% in science. Eighth grade was particularly weak, including just 6.12% proficiency in math, raising concerns about preparation for high school. Across the district, math is a broad challenge, and the sharp drop from elementary to middle school deserves attention. Families may want to ask about middle-school math and science supports, eighth-grade transition planning, attendance, and intervention programs while also recognizing the high school’s strong improvement and ELA performance.
