Issaquah School District runs Issaquah's public schools

Every assigned public school in Issaquah is a Issaquah School District school (15 of 15).

About Schools in Issaquah, Washington
Issaquah, Washington has 15 ranked public schools with a city-wide average score of 7.5 out of 10. Nine of those 15 schools — 60% — score 7 or above. That balance is significant for parents comparing districts: strong performance is spread across Issaquah's campuses rather than confined to a small number that families must compete for specifically.
The top five tell the fuller story. Endeavour Elementary School leads the city at 9.5 out of 10. Challenger Elementary follows at 9.2, and Grand Ridge Elementary sits at 9.1. Clark Elementary (8.9) and Beaver Lake Middle School (8.6) complete the top five. Four of those five are elementary schools, a pattern that makes Issaquah's early grades the district's clearest strength and a natural focus for families still in the enrollment planning stage.
Middle school performance extends that consistency. Beaver Lake Middle School scores 8.6, placing it fifth in the city and above the 7.5 city-wide average. That average signals something important: with nine schools scoring 7 or above and a mean of 7.5 across all 15, the schools outside the top five are supporting the overall number, not pulling it down. Issaquah's floor is as noteworthy as its ceiling.
Practical takeaway for parents: the 60% rate of schools scoring 7 or above means consistent quality is accessible across most of the district, not just at the top. Families prioritizing the highest-ranked campuses should center their search on Endeavour, Challenger, and Grand Ridge — all three clear 9.0 and sit at the elementary level. Families with less ability to choose a specific campus still find favorable odds in Issaquah: nine of 15 schools score 7 or above, and the 7.5 district average signals a field deep enough to support good outcomes regardless of assignment.
