Summary

Timberline Middle School is a top-ranked public school serving 788 students in grades 6-8 in Redmond, Washington, as part of the highly-regarded Lake Washington School District.

Timberline is a consistent leader, ranking in the top 10 middle schools in Washington for the past five years. Its students significantly outperform state averages, with over 80% proficient in English, Math, and Science. This excellence is achieved with a large student body, setting it apart from other top schools like the much smaller Stella Schola. A key strength is its effective support for all students; it ranks exceptionally high for special education students and performs very well across different student groups, indicating strong and equitable teaching practices.

Within its own district, Timberline is among a cluster of outstanding schools, often closely compared with peers like Evergreen Middle School. Interestingly, its high performance isn't tied to the highest spending or smallest classes in the area. The school's success is part of a broader "Lake Washington effect," which becomes clear when compared to schools in neighboring districts, such as the lower-performing Highland Middle School in the Bellevue School District, despite that school having higher per-student funding.
