Summary

Endeavour Elementary School is a K–5 school in Issaquah serving 473 students in the Issaquah School District, an area surrounded by several high-performing elementary schools, including one nearby school in the Lake Washington School District. The school ranks 11th out of 1,138 Washington elementary schools for 2025–2026, placing it in the 99th percentile and earning a five-star rating. Its student-teacher ratio is 15.7 to 1, and its long-term record is particularly impressive: it has ranked among Washington’s top 50 schools in every available year since 2017–2018.

Academic results are excellent across subjects. In 2025–2026, 86.1% of students were proficient in English Language Arts, 88.1% in math, and 87.38% in science—well above both district and state results. Math is the school’s clearest current strength: its proficiency rate exceeded the district by 12.32 percentage points and remained close to the area’s leaders. Fifth-grade performance was also notable, including 90.29% proficiency in ELA and 86.41% in math. Recent results dipped modestly from the prior year, especially in science, but they remain exceptional. State-suppressed third- and fourth-grade math results should be treated as unknown, not as low performance.

Among nearby schools with current rankings, Cascade Ridge Elementary ranked higher in some latest subject results, while Grand Ridge Elementary and Sunny Hills Elementary were also close competitors. Endeavour nevertheless ranked ahead of Creekside Elementary, Cedar Trails Elementary, Challenger Elementary, and Issaquah Valley Elementary in the supplied comparisons. Strong subgroup rankings, including for special education and low-socioeconomic-status students, further suggest broad school effectiveness.
