Enrollment stability & demand — 2024-25

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

Critical
Sharp demand downturn hidden by elite retention.

Casterlin High's enrollment is shrinking far faster than Humboldt County (school +0.0% vs. county +26.5%). Stability of 100.0% means every family you keep is one fewer; the leverage is at recruitment, not retention. This is the case the high stability number alone would hide.

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 — 2020-21

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
0.0%
0 of 11 students

Low and stable absenteeism — students are engaged and showing up. The leading indicator is healthy.

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 Southern Humboldt Joint 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).
