Straight-line extrapolation of the recent annual rate — a what-if, not a forecast of intent. Default = California's LCFF base grant for grades 9–12 ($12,423/ADA). Edit the figure to match your school.

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.

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: total enrollment.

Chronic absent
17.4%
82 of 470 students

Absenteeism is up 10.9 pp since 2016-17. A rising absenteeism trend often precedes formal departure — worth investigating which subgroups are driving it.
