California College-Going Rate
72.3% 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 74.6% had enrolled — CDE publishes a 16-month window alongside the 12-month one, 97 students.
Up 7.6 points from the 2021-22 class (64.7%).
Where the 2022-23 class enrolled
In California — 87 students (66.9%)
Out of state — 7 students (5.4%)
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.
College readiness
Getting ready for college
These come from the state and federal files, not from UC — so they are here whether or not Mueller Charter (robert L.) has a UC admissions record.
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.
Source: California Assessment of Student Performance and Progress (CAASPP) Smarter Balanced research files. Benchmarks limited to non-virtual public & charter HS with ≥30 tested students.
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
Source: California Department of Education, Census Day Enrollment 2025-26 (HS grades 9–12). Δ shown when shift is ≥1 pt since 2023-24. Categories below 0.5% omitted.
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 10.4 pp since 2016-17. A rising absenteeism trend often precedes formal departure — worth investigating which subgroups are driving it.
Source: California Department of Education, Chronic Absenteeism 2024-25. Benchmarks limited to non-virtual public & charter HS with ≥100 eligible students. CDE didn't publish a usable 2019-20 file (COVID).

Enrollment stability & demand — 2024-25
Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the San Diego County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Mueller Charter (robert L.) outperformed San Diego County on enrollment (school +64.2% vs. county -6.9%) AND maintains 95.3% stability. Replicable model — worth documenting what's working.
26 of 554 students who enrolled at Mueller Charter (robert L.) this year didn't maintain continuous enrollment (4.7% 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.
