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.

Diocese 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.

📊 What this number means

Justin-Siena High School's UC Reach of 38.1% is in the top quartile statewide (median 18.5%; top 25% bar 32.0%) — but it's still below the top-10% bar of 53.3%.

For context, the elite tier (top 1%) clears 102.7% — a gap of 65 pp from where this school sits.

Overall, Justin-Siena High School's UC Reach is higher than 81% of California high schools (1105 ranked).

UC Application Reach ⓘ

189.4%

303 applications

Most seniors are applying to at least one of the six most selective UCs (applications counted at each campus).

In context: CA median 78.3% · Top 10% statewide ≥ 245.8% · higher than 83% of CA HS.

UC Yield Rate ⓘ

26.2%

16 enrolled of 61 admitted

Yield vs. Enrollment Reach: Yield answers "of UC admits, what % chose UC?" — denominator is just the admits. A small admitted cohort can post a low yield even when the school sends a healthy share of its class to UC.

UC Enrollment Reach ⓘ

10.0%

16 enrollees / 160 seniors

Enrollment Reach vs. Yield: Reach answers "of the whole senior class, what % ended up at UC?" — denominator is everyone. High Yield with low Enrollment Reach is common at elite privates: most admits matriculate, but the school sends most of its class to non-UC selective colleges.

Admit rate vs. CA peer average, by campus ⓘ

How does this school's admit rate at each UC compare to other CA schools whose applicant pool averages the same GPA? Based on 2024 (latest GPA available).

Campus	Applicant GPA (avg)	Actual admit rate	CA peer avg	Δ	Verdict
UC Berkeley	4.09	20.0%	16.7%	+3.3pp	On target
UCLA	4.09	17.1%	9.4%	+7.6pp	Over
UC San Diego	3.98	21.1%	21.0%	0.0pp	On target

UC Davis	3.97	34.0%	31.0%	+3.0pp	On target

"Applicant GPA" is the average GPA of this school's UC applicant pool — not an individual student GPA. "CA peer avg" is the application-weighted statewide admit rate at this school-pool GPA, fit separately per campus. At any given pool GPA, real admit rates span widely (UCSD ranges 8% → 65% across CA schools) because UCs use comprehensive review — context-of-opportunity, geography, demographics, and applicant essays all weigh in beyond GPA. A large negative residual flags this school is admitted at a meaningfully lower rate than other CA schools at the same pool GPA — not that students here were "rejected at expected rate X." "Over" / "Under" use a ±5-point band. Campuses with fewer than 5 applicants are omitted.

⚠ Campus-level totals may count one student admitted to multiple UC campuses more than once. Admit Volume metrics are not the same as UC Reach, which requires unique-student counts. See methodology →

What This Means

A large share of the senior class applies to UC, indicating strong college-going culture and UC pipeline development.

A large share of the class applies to UC, so the admit rate runs lower than the application volume alone might suggest — expected when many students apply broadly, including to reach campuses. UC Reach (which credits every admit relative to the class) is the truer read of how the class fares: a strong Reach alongside a moderate admit rate is healthy, not a contradiction.

UC Reach is solid. A meaningful share of the senior class is achieving UC admission, and there is likely room to grow both application volume and admission outcomes.

Students are earning UC admission but enrolling elsewhere at a notable rate. This may reflect competition from private colleges, out-of-state flagships, cost considerations, or UC campus fit. Student outcome surveys can clarify.

The school generates broad UC access, but fewer students are reaching the most selective UC campuses (UCLA, Berkeley, UCSD, UCSB, UCI). Targeted academic enrichment and campus-fit advising may help.

UC Reach has declined meaningfully year-over-year. This should be reviewed in context of applicant volume, GPA trends, course rigor changes, and peer-school performance before drawing conclusions.

Note: admit counts used here are campus-level totals. A student admitted to both UCLA and UCSD is counted twice. When UCOP unique-student data becomes available it will be loaded automatically and the labels will update.
