Summary

Timberline High School is a grades 9–12 comprehensive school in Lacey, Washington, serving about 1,401 students in the North Thurston Public Schools district, a moderately sized and economically mixed community in the South Puget Sound area. The school ranks 175th of 396 Washington high schools, placing it in the 56th percentile with a three-star rating—roughly in the middle statewide and close to River Ridge High School.

Timberline’s clearest academic strength is English Language Arts: 72.05% of students were proficient in 2025–2026, well above both district and state rates of about 52%. That result was slightly below North Thurston High School, Olympia High School, and Tumwater High School, but ahead of River Ridge. Mathematics is the major concern: proficiency was 24.48%, below the district’s 38.63% and the state’s 43.11%, and it has declined over several years. Science was also below district and state averages at 43.67%. These results create a striking gap between literacy and math achievement and suggest that math, followed by science, should be the school’s most urgent instructional focus.

Graduation outcomes are more encouraging than test scores. Timberline’s 91.5% graduation rate was higher than district and state rates and exceeded those at North Thurston and River Ridge, although it trailed Olympia and Tumwater. Its 6.3% dropout rate was also below district and state levels. Student-group results are uneven: special education students ranked in the 15th percentile statewide, and military-connected students ranked in the 18th percentile, signaling areas for closer attention. Overall, Timberline appears relatively effective at keeping students on track to graduate and supporting ELA success, while needing sustained improvement in mathematics, science, and services for specific student groups.
