Timbercrest Middle School, Woodinville WA

Original Research by School Decision on Timbercrest Middle School

Timbercrest Middle School, a regular public school in Woodinville serving sixth through eighth grades, is part of the Northshore School District. The school sits in a suburban setting at the edge of the Sammamish River Valley, a mix of residential neighborhoods, wine-tourism districts, and light industrial areas about a short drive northeast of Seattle.

Academically, Timbercrest posts results that place it among the strongest middle schools in the region. In state assessments for the most recent testing year, a substantial majority of students met proficiency in English language arts across all three grades, and a similar majority did so in math. Science results for eighth graders were also high. When compared against other districts in King County, Timbercrest’s overall proficiency index falls in the top quartile, a clear strength for families focused on academic rigor. The school’s student body is predominantly white, with Asian and Hispanic students each making up a modest share and small numbers of other racial groups. The share of students qualifying for free or reduced-price meals is very low, reflecting the surrounding community’s affluence. Data on students with disabilities and English learners was not available, so a parent may want to ask the school directly about those supports.

The peer environment here is shaped by the community. Woodinville is an expensive housing market, with home values well above national and state benchmarks. The city is known for its wine industry, tasting rooms, and a defined Town Center, but it remains car-dependent; schools sit on separated campuses rather than clustered downtown. The Northshore district recently opened Ruby Bridges Elementary, a new school that adjusted attendance boundaries for families in the northern part of the district, which may affect feeder patterns for Timbercrest. The school itself draws from a set of neighborhoods that are largely residential and well-established.

Timbercrest is a middle school only, so there is no graduation rate to report. Information about programs, course access, discipline, and attendance was also absent from the available data. Families looking into elective offerings, advanced coursework, or the school’s approach to student conduct will need to check with the school or district for those details. What the data does show is a school with consistently high test performance in a prosperous, growing suburban community, fitting for parents who prioritize strong academic results and want a middle school that reflects the economic character of its area.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
