SAT / ACT participation
CRDC federal data · 2020-21Bottom 1% by test-taker volume
Source: federal Civil Rights Data Collection (CRDC 2020-21). Volume — not score — is what's reported here. A higher count means more students at this school are entering the college admissions pipeline. Note: 2020-21 was COVID-disrupted; some districts (especially those that stayed remote longer) report unusually low or zero takers.

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.

Student composition — 2025-26
HS grades 9–12 racial/ethnic composition and program subgroups, from CDE Census Day Enrollment. Two-year shift shown when ≥1 pt — surfaces how the community served has changed since 2023-24.

Program subgroups

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 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.
Six Rivers Charter School outperformed Humboldt County on enrollment (school +20.8% vs. county -1.9%) 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.
10 of 117 students who enrolled at Six Rivers Charter School this year didn't maintain continuous enrollment (8.5% non-stability). Mid-year transfers, dropouts, and other exits are all counted.
Stability by student group
Nearest peer high schools
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.
