Top 25% ELA & Math · SBAC (CA) Top 5% Attendance (lowest chronic absenteeism) in CA

A parent's read

About 2 in 3 students read and write at grade level. On the state's own 11th-grade test, 71% met or exceeded the college-readiness bar — the top quarter of California high schools (statewide: 54%).
Kids actually show up. Only 2% of students are chronically absent, versus about 23% statewide — day-to-day engagement most schools would envy.
Most grads aim beyond the UC system. Seniors file only ~0.1 UC applications each — families here mostly target CSU, private, or out-of-state colleges, so judge this school on more than its UC numbers.
One question for any counselor: who should still test? Plenty of strong students skip the SAT/ACT now — but merit scholarships at dozens of colleges still key off scores. Ask how the school decides who should still sit for one.

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.

Kids show up: 2% are chronically absent versus about 23% statewide — engagement most schools would envy.

Enrollment stability & demand — 2024-25

Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the El Dorado County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.

90% of students who start the year here finish it here.

Mixed signal

Outperforming on demand; some mid-year churn to look at.

Sky Mountain Charter School is recruiting families faster than El Dorado County is shrinking (school +16.1% vs. county -4.8%), but 63 students didn't make it to year-end. The recruitment engine works; the mid-year exits are worth understanding.

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.

UC Yield Rate ⓘ

N/A

Yield vs. Enrollment Reach: Yield answers "of UC admits, what % chose UC?" — denominator is just the admits. A small admitted cohort can post a low yield even when the school sends a healthy share of its class to UC.

UC Enrollment Reach Score ⓘ

N/A

— enrollees / 114 seniors

Enrollment Reach vs. Yield: Reach answers "of the whole senior class, what share ended up at UC?" — denominator is everyone. High Yield with low Enrollment Reach is common at elite privates: most admits matriculate, but the school sends most of its class to non-UC selective colleges.

A-G Completion ⓘ

Only 1 in 4 graduates finish the courses UC and CSU require — below the state norm. Worth asking how course access and planning work here.

UC Admit Rate %

UC Reach Score (where available)

UC Admits (count, right axis)

Class size from CDE grade 12 enrollment. Campus-level data: applicant and admit totals count a student once at EACH campus. A senior admitted to UCLA and UC San Diego adds 2 to the admit total, so the total can exceed the senior class — that is the metric working as defined, not an error. The admit RATE is unaffected: both its numerator and denominator are campus-level.

Campus Breakdown — 2025

Campus	Applicants	Admits	Enrollees	Admit Rate	UC Reach Score	Yield	Avg GPA (App)	Avg GPA (Adm)
UCLA → Elite	5	—^†	—^†	—^†	—^†	—	4.09	—^†
UC San Diego → Selective	5	—^†	—^†	—^†	—^†	—	4.12	—^†
UC Irvine → Selective	5	—^†	—^†	—^†	—^†	—	3.97	—^†

† = 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

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: 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.
