Enrollment stability & demand — 2024-25

Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the Sonoma County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.

Critical
Compounding decline on both vectors.

Enrollment -50.0% vs. county -0.1% AND stability (37.9%) below the county median. Recruitment and retention both under pressure — likely a foundational rather than tactical problem. Chronic absenteeism is also at 63.0% (up -37.0 pts from 2016-17) — engagement and demand are both signaling decline.

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.

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.

Chronic absent
63.0%
17 of 27 students

Absenteeism is down 37.0 pp since 2016-17. Engagement improving — a positive trajectory worth understanding and reinforcing.

SBAC academic outcomes — grade 11, 2023

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.
