No SBAC data for private schools — and that's not the metric you want anyway
California's Smarter Balanced (CAASPP) assessment is administered by the state, by statute, to public & charter schools only. Private schools don't sit for it. That's why the SBAC card is missing on this profile — not a data gap on our side, a deliberate scope of the state's testing program.
For private schools, UC Reach is the stronger academic signal anyway. SBAC measures grade-11 inputs (proficiency on a state standard); UC Reach measures outputs (who actually got into the most selective UCs). For private-school families weighing tuition against college outcomes, the outputs are the relevant signal.

Financial profile — IRS Form 990, FY2023
From 13 years of Form 990 filings via ProPublica Nonprofit Explorer (free public IRS data). The school's tax filings show financial scale, fundraising health, and endowment trajectory — signals that drive board-level conversations about tuition pricing, financial-aid capacity, and capital projects.
Source: IRS Form 990 via ProPublica Nonprofit Explorer (EIN 942165246). Tuition-per-student is total program-service revenue divided by latest enrollment — a rough average that includes auxiliary revenue (athletics, food service, etc.); the actual published tuition can differ. Form 990 is filed annually under penalty of perjury, so the financial scale figures are authoritative.
Diocesan context — Diocese of Santa Rosa
DioceseDiocese of Santa Rosa is the canonical governance body for Catholic schools in this region — board policy, tuition guidance, and shared services typically originate here. Visit the diocesan website →
Financial figures aren't shown because Catholic (arch)dioceses don't file IRS Form 990 — they're covered by the USCCB Group Ruling (GEN 0928), which exempts dioceses, parishes, and parochial schools from individual filing. School counts above are hand-compiled from each diocese's published schools-department information.
