Skyline High School is a high school in Issaquah School District. The local dataset puts it at grade span 9-12 with enrollment of 2265. The headline academic number: 77.4% combined ELA/math meeting standard across the available three-year data, with 78.7% in the latest year.

The useful question is not just whether the scores are high. It is whether the school combines academics, access, peer depth, and day-to-day fit in a way that works for a specific child.

The Short Version

  • Local structured data: 77.4% combined ELA/math over available three-year data; 85.3% ELA and 69.5% math.
