SBAC academic outcomes — grade 11, 2025
Share of grade-11 students meeting or exceeding the California standard on Smarter Balanced ELA and Math. This is the academic-readiness signal that pairs with UC Reach (post-grad outcomes), stability (retention), and absenteeism (engagement). Note: statewide median Math is only ~20% — a school at 20% isn't an outlier; one at 45%+ genuinely is.

Chronic absenteeism — 2024-25
Share of students missing 10% or more of expected attendance — the leading indicator that often precedes the demand decline shown above. Families disengaging tend to raise absenteeism first, then formally leave. Basis: grades 9–12.
Absenteeism is down 4.1 pp since 2016-17. Engagement improving — a positive trajectory worth understanding and reinforcing.

Enrollment stability & demand — 2024-25
Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the El Dorado County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Sky Mountain Charter School is recruiting families faster than El Dorado County is shrinking (school +16.1% vs. county -4.8%), but 63 students didn't make it to year-end. The recruitment engine works; the mid-year exits are worth understanding.
63 of 613 students who enrolled at Sky Mountain Charter School this year didn't maintain continuous enrollment (10.3% non-stability). Mid-year transfers, dropouts, and other exits are all counted.

Source: California Department of Education, Stability Rate 2024-25. Benchmarks limited to non-virtual public & charter HS with ≥100 cumulative enrollees so by-design-high-churn continuation schools don't dominate the bottom of the distribution. Cumulative enrollment counts every student on the rolls during the year, so it can exceed peak-day enrollment.
