Cascadia Elementary: The Numbers Are Huge, But So Is The Asterisk

Cascadia Elementary is an elementary school in Seattle School District No. 1. The local dataset puts it at grade span PK, 2-5 with enrollment of 565. The headline academic number: 94.7% combined ELA/math meeting standard across the available three-year data, with 96.2% in the latest year.

But this is not a normal neighborhood-school comparison. Local data shows 94.3% Highly Capable enrollment and labels access as Special program eligibility. That makes the school important, but it also makes naive ranking misleading.

The Short Version

  • Local structured data: 94.7% combined ELA/math over available three-year data; 95.0% ELA and 94.3% math.
  • Important caveat: the local data does not show full three-year ELA/math coverage. ELA years are 2022-23;2023-24;2024-25; math years are 2022-23.
  • Access is the first filter: Special program eligibility. SPS Highly Capable identification and placement process using multiple measures.
  • Program status is a live issue: Seattle Public Schools announced that starting in 2025-26 it would continue the Highly Capable hybrid model for the next three years, allowing eligible grades 2-5 families to choose between the existing cohort pathway and neighborhood-school services (Seattle Public Schools Highly Capable Program Update).
  • There is public evidence of advanced peer depth: Cascadia Elementary placed first overall in the Division 5 Sweepstakes for Washington State in March 2026 (Math League Results).
  • The culture evidence does not scream grind: The school has a strict no graded homework policy, focusing instead on in-class work completion (Cascadia 2025-26 CSIP).
  • The surrounding block group is High for kid density, about 6.2 estimated kids per typical block.
