Enrollment stability & demand — 2024-25
Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the Alameda County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Roy A. Johnson High's enrollment is shrinking 25.1× the county rate (school -17.6% vs. county +0.7%). 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. Chronic absenteeism is also at 33.3% (up +6.4 pts from 2016-17) — engagement and demand are both signaling decline.
0 of 18 students who enrolled at Roy A. Johnson High this year didn't maintain continuous enrollment (0.0% 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: grades 9–12.
Absenteeism is in the typical CA HS range. Worth monitoring alongside the demand and retention signals above.

District financial profile — Castro Valley Unified (FY2020)
From 4 years of NCES F-33 filings (the federally-mandated district finance survey). Public schools don't have their own books — the district does. These figures show the financial scale, revenue dependence, instruction-vs-overhead mix, and long-term debt that shape what a school can sustain.
Local: 27.2%
Federal: 11.0%
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 Castro 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).
