Sky Mountain Charter scores 42 of 100 on SchoolScope's Scope Score — the 54th percentile of 5,744 California elementary schools (CDE CAASPP 2025).
Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
Most rating sites would stop at “39% proficient” and call it done. Sky Mountain Charter deserves a closer read. The school sits in Placerville, where one in three students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The headline number: 1.6% chronic absenteeism — versus 17.9% statewide. Attendance is the quietest strong signal a school can post.
As a charter, Sky Mountain Charter enrolls by application, not address — the score reads the same, the enrollment path doesn't.
