Top 25% ELA & Math · SBAC (CA) Top 10 Attendance (lowest chronic absenteeism) in Humboldt

A parent's read

  • About 2 in 3 students read and write at grade level. On the state's own 11th-grade test, 69% met or exceeded the college-readiness bar — the top quarter of California high schools (statewide: 54%).
  • Worth asking about on a tour: counselor load. One counselor serves about 357 students here — above the 250-to-1 level counseling experts recommend. Ask how junior-year college advising actually gets covered.

California College-Going Rate

80% of the 2022-23 graduating class enrolled in college within a year.

The share of 2022-23 graduates who enrolled at a college anywhere in the U.S. within 12 months, per the National Student Clearinghouse match the California Department of Education publishes.

Within 12 months
80%
of 25 graduates

Give the same class four more months and 84% had enrolled — CDE publishes a 16-month window alongside the 12-month one, 21 students.

Up 22.3 points from the 2021-22 class (57.7%).

Where the 2022-23 class enrolled

In California — 18 students (72.0%)

California State University 8.0% 2

CDE puts each graduate in one bucket only — whichever kind of college they were enrolled in longest — so these add up to the rate above. That is a different count from the UC Reach Score on this page, which counts a student at every UC campus that admitted them.

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.

About 2 in 3 students read and write at grade level — the top quarter of California high schools.
About 4 in 10 students do math at grade level — the top quarter of California high schools.

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.

29% of students miss 10%+ of school days — above the state's ~23%. Ask what the school is doing about engagement.
Chronic absent

34 of 116 students

Absenteeism is up 7.3 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 Humboldt County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.

92% of students who start the year here finish it here.
Healthy
Best in class — winning on demand and retention.

Six Rivers Charter School outperformed Humboldt County on enrollment (school +20.8% vs. county -4.8%) AND maintains 91.5% stability. Replicable model — worth documenting what's working. Chronic absenteeism is rising (29.3%, +7.3 pts since 2016-17) — a watch signal worth monitoring as a leading indicator.

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.

= 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 is measured against the whole senior class. See methodology →

What This Means

Note: the UC Reach Score sums campus-level admits across the top-six UC campuses, so a student admitted to both UCLA and UCSD is counted at each. It reflects competitive admit volume relative to class size — admit-events, not distinct students — which is why a Score can exceed 100.
