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.

Stability rate
92.4%
218 of 236 students

18 of 236 students who enrolled at Sonoma Charter this year didn't maintain continuous enrollment (7.6% 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.

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
23.2%
54 of 233 students

Absenteeism is up 18.0 pp since 2016-17. A rising absenteeism trend often precedes formal departure — worth investigating which subgroups are driving it.

Source: NCES F-33 Annual Survey of School System Finances (Urban Institute Education Data API). Latest year currently published: FY2020. F-33 is a district-level federal filing — it reflects the Sonoma Valley Unified as a whole, not this individual school's books. Revenue mix shows where the district's dollars come from (state aid dominates in CA via LCFF). Instruction share is current expenditure on instruction ÷ total current expenditure (national benchmark ~60%). Long-term debt is end-of-year outstanding (mostly facilities bonds).
