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.

Best in class — winning on demand and retention.

Corning Union High School outperformed Tehama County on enrollment (school +8.1% vs. county +5.8%) AND maintains 86.0% stability. Replicable model — worth documenting what's working.

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.

Chronic absent
13.5%
136 of 1,007 students

Low and stable absenteeism — students are engaged and showing up. The leading indicator is healthy.

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.

UC Admits (count, right axis)

Class size from CDE grade 12 enrollment. Campus-level data — applicant/admit totals may count a student at multiple campuses more than once.

UC Berkeley → Elite
UCLA → Elite 6 3.42
UC San Diego → Selective
UC Santa Barbara → Selective
UC Davis → 6 3.32
⚠ 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.
