Endeavour Elementary School

Endeavour Elementary is a public K–5 school in Issaquah, Washington, serving 478 students. It holds a composite score of 9.1 out of 10, earning the top-tier Exceptional rating on the MySchoolScout scale — a mark that reflects consistent, measurable performance across every scoring category. Academic and growth scores tell the clearest story.

Endeavour posts a 9.7 on academics and a 9.5 on growth, a combination that's harder to achieve than either number alone: it means students arrive performing well and keep accelerating. A student-teacher ratio of 15.9 to 1 supports that momentum, giving teachers more room for individualized instruction than many comparable elementary schools provide. The rankings put those results in context.

Endeavour sits at #1 among all 9 public schools in Issaquah, and places #41 out of 2,225 public schools in Washington state — outperforming 98% of schools statewide. Among elementary schools specifically, it ranks #40 out of 1,202. Few schools in Washington match both the academic ceiling and the growth trajectory Endeavour demonstrates year over year.

Families weighing their options in Issaquah will find this is the performance benchmark every other school in the area is measured against.

Located in a rural area, Endeavour Elementary School may involve longer commutes for some families. Rural schools often serve as community anchors and may have smaller class sizes, but parents should consider transportation logistics, after-school program availability, and access to specialized services.
