🏛️ Federal Title I context

High-poverty school

Title I Schoolwide eligible

80.0%
FRPL rate — % of students who qualify for the federal Free or Reduced-Price Lunch program. This is the underlying federal income-eligibility signal Title I designations are computed from (ESEA Sec. 1113).
0% (no FRPL) 35% TA · 40% Schoolwide 100% (universal FRPL)

≥75% of students qualify for free/reduced lunch. These schools qualify for the highest tier of federal Title I funding and typically receive extra wraparound services. Academic outcomes vary widely — check the state assessment + grad-rate tiles.

Source: NCES Common Core of Data, free/reduced-price lunch eligibility. The actual Title I designation is a district decision and may differ from eligibility — but the federal eligibility math is what we show here. We don't claim to assert whether the district formally chose to enroll this school in Title I.

SBAC academic outcomes — grade 11, 2025

Share of grade-11 students meeting or exceeding the California standard on Smarter Balanced ELA and Math. This is the academic-readiness signal that pairs with UC Reach (post-grad outcomes), stability (retention), and absenteeism (engagement). Note: statewide median Math is only ~20% — a school at 20% isn't an outlier; one at 45%+ genuinely is.

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 up 6.3 pp since 2016-17. A rising absenteeism trend often precedes formal departure — worth investigating which subgroups are driving it.

Enrollment stability & demand — 2024-25

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

Mixed signal
Demand outpacing county is masking internal churn.

Enrollment growth is beating Contra Costa County (+3.0% vs. -3.2%), but 344 of 1596 students didn't maintain continuous enrollment. Why are families leaving once enrolled? Chronic absenteeism is also at 33.7% (up +6.2 pts from 2016-17) — engagement and demand are both signaling decline.

Diablo 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).
