🏛️ Federal Title I context

High-poverty school

Title I Schoolwide eligible

82.4%
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.

Enrollment stability & demand — 2024-25

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

UC funnel — which kids are getting in at what GPA

Combining the school's applicant pool GPA, admit pool GPA, actual admit rate, and statewide CA admit rates by individual GPA band, we can read which GPA tiers tend to get in — and which don't.

🎯 Who's actually getting into UC from Corning Union High School
Campus 4.00+ GPA 3.70–3.99 GPA 3.30–3.69 GPA < 3.30 GPA
UC Santa Barbara Strong shot Moderate Long odds Filtered out
UC Davis Strong shot Real shot Moderate Filtered out
Strong shot = ≥30% statewide admit rate at this band · Real shot = 10–29% · Moderate = 5–9% · Long odds = 1–4% · Filtered out = under 1%. Tiers map this school's likely outcomes by GPA tier using statewide CA admit rates from UCOP 2024.

How we infer the tier labels: Each tier comes from the statewide CA admit rate at that GPA band at that UC. The "vs peers" column compares this school's lift (admit GPA − applicant GPA) to the average lift at ~100–300 other CA schools with similar applicant pool GPA. What this isn't: a guarantee. UC comprehensive review weighs essays, course rigor, demographics, and context-of-opportunity beyond GPA. A 3.9 with strong context can land an admit; a 4.0 with weak essays can be denied. Use as a baseline expectation, not a verdict. Per-campus year is shown when it differs from the headline year (UCOP doesn't always publish admit-GPA for every campus every year).

= UCOP-suppressed (count below 3 students, hidden for privacy — actual value is 0, 1, or 2, not necessarily zero). 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 relatively small share of the senior class is entering the UC application pipeline. This may signal limited A-G completion, UC awareness gaps, or counseling capacity constraints. Broadening access is the highest-leverage opportunity for this school.
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.
