Summary:

Issaquah School District includes 28 schools serving students from elementary through high school in the Issaquah area of Washington, with 16 elementary schools, 6 middle schools, 5 high schools, and 1 alternative school. The district serves approximately 19,000 students and ranks 3rd among 238 Washington districts. Overall results are considerably above state averages: district proficiency is 79.04% in ELA, 75.78% in math, and 78.36% in science, compared with 52.81%, 43.11%, and 50.95% statewide.

Several schools stand out for exceptional academic performance. Among elementary schools, Cascade Ridge Elementary leads with 91.34% ELA and 92.61% math proficiency, while Endeavour Elementary School, Grand Ridge Elementary, Discovery Elementary, and Cougar Ridge Elementary also rank among the district’s strongest. Pine Lake Middle School and Beaver Lake Middle School are especially notable, ranking 2nd and 4th statewide, respectively. Other middle schools, including Issaquah Middle School and Maywood Middle School, have lower current proficiency but have shown meaningful ranking or subject-area improvement.

The three comprehensive high schools have excellent graduation outcomes: Skyline High School leads with a 97.8% graduation rate and a 0.7% dropout rate, followed by Liberty Senior High School and Issaquah High School. ELA performance is strong and consistent, while math is the main area for improvement. Families should interpret Gibson Ek High School, Echo Glen School, and Issaquah Special Services separately because they serve specialized populations and programs. Suppressed data indicates unavailable information, not zero performance. Overall, the district’s main opportunity is improving consistency among lower-performing regular schools while sustaining the exceptional results of its top campuses.
