California College-Going Rate
55.6% 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.
Give the same class four more months and 55.6% had enrolled — CDE publishes a 16-month window alongside the 12-month one, 10 students.
Up 26.4 points from the 2021-22 class (29.2%).
Where the 2022-23 class enrolled
In California — 10 students (55.6%)
Out of state — 0 students (0.0%)
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.

CDE builds the rate by matching California high school completers to National Student Clearinghouse enrollment records; we publish CDE’s aggregates and hold no student-level data.
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.
Race / ethnicity
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.
Low and stable absenteeism — students are engaged and showing up. The leading indicator is healthy.

Enrollment stability & demand — 2024-25
Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the Lassen County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Enrollment -32.0% vs. county +16.2% AND stability (66.7%) below the county median. Recruitment and retention both under pressure — likely a foundational rather than tactical problem.
31 of 93 students who enrolled at Thompson Peak Charter this year didn't maintain continuous enrollment (33.3% 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.
