Summary:
Winlock-area families have four schools serving approximately 856 students from preschool through 12th grade: Winlock Miller Elementary (PK–5), Winlock Middle School (6–8), Winlock Senior High (9–12), and the smaller K–6 Evaline Elementary School. Three schools are part of the Winlock School District, while Evaline belongs to the separate Evaline School District. The schools vary considerably in size, performance, and available data, so parents should consider both overall results and the stability of results at each school.
Winlock Senior High is the strongest recent improvement story. Its ranking rose from the 19th percentile to the 57th percentile between 2023–2024 and 2025–2026, and it had the area’s strongest reported ELA and science results, with 63.04% and 46.67% proficiency. Its 82% graduation rate was close to the state rate, although math remained a clear weakness at 30.43%. Evaline Elementary School had the strongest elementary results, with 55.88% proficiency in ELA and 50% in math, but its enrollment of only 55 students and several suppressed results make year-to-year comparisons less stable. Winlock Miller Elementary, the largest school, showed encouraging math improvement to 33.72% and exceeded its district in math and science, though overall achievement remained modest.
Winlock Middle School is the most urgent academic concern. It ranked in the 6th percentile in 2025–2026, with 26.14% proficiency in ELA, 11.84% in math, and 13.73% in science. Eighth grade was particularly weak, including just 6.12% proficiency in math. The sharp drop from Miller to middle school in math and science suggests that instructional alignment, intervention, and the transition into high school deserve attention. Overall, parents will find the greatest recent momentum at Senior High, promising but small-school results at Evaline, improving math at Miller, and the greatest need for targeted support at Middle School.
