- About 2 in 3 students read and write at grade level. On the state's own 11th-grade test, 63% met or exceeded the college-readiness bar — well above the state as a whole (statewide: 54%).
- Elite admits are rare — here and everywhere. Berkeley and UCLA admitted 3 of this class's 195 UC applications. The strong middle campuses — San Diego, Santa Barbara, Irvine, Davis — are where most real UC outcomes happen.
- Most grads aim beyond the UC system. Seniors file only ~0.5 UC applications each — families here mostly target CSU, private, or out-of-state colleges, so judge this school on more than its UC numbers.
- Who actually gets in: the top half of applicants. UC admits from this school average about a 4.1 weighted GPA — noticeably above the average applicant. Being near the top of THIS school's class is what converts to admits; UC reads applications in each school's own context.
- 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.

California College-Going Rate
75.3% 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 77.4% had enrolled — CDE publishes a 16-month window alongside the 12-month one, 294 students.
Up 3.7 points from the 2021-22 class (71.6%).
Where the 2022-23 class enrolled
In California — 276 students (72.6%)
Out of state — 10 students (2.6%)
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.

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 7.1 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 Los Angeles County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Los Altos High School's enrollment is shrinking 3.8× the county rate (school -20.0% vs. county -5.3%). Stability of 90.6% means every family you keep is one fewer; the leverage is at recruitment, not retention. This is the case the high stability number alone would hide.
156 of 1,668 students who enrolled at Los Altos High School this year didn't maintain continuous enrollment (9.4% non-stability). Mid-year transfers, dropouts, and other exits are all counted.

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.
District financial profile — Hacienda la Puente Unified (FY2020)
From 4 years of NCES F-33 filings (the federally-mandated district finance survey). Public schools don't have their own books — the district does. These figures show the financial scale, revenue dependence, instruction-vs-overhead mix, and long-term debt that shape what a school can sustain.
Local: 16.8%
Federal: 14.8%
Source: NCES F-33 Annual Survey of School System Finances (Urban Institute Education Data API). Latest year currently published: FY2020. F-33 is a district-level federal filing — it reflects the Hacienda la Puente Unified as a whole, not this individual school's books. Revenue mix shows where the district's dollars come from (state aid dominates in CA via LCFF). Instruction share is current expenditure on instruction ÷ total current expenditure (national benchmark ~60%). Long-term debt is end-of-year outstanding (mostly facilities bonds).
Los Altos High School sent 195 applications to the six most selective University of California campuses and 22.1% were admitted, producing a UC Reach Score of 12 (top-6 UC admits per 100 seniors, counting a student at each campus that admitted them) — 7 points below the California median of 19, higher than 25% of California high schools. The school produces 0.8 UCLA + UC Berkeley admits per 100 seniors.

Higher than 25% of California high schools (1107 ranked, ≥50 seniors)
Los Altos High School's UC Reach Score of 12 is below the California median (19). The top 10% of CA schools achieve 53 or higher.
But in Los Angeles County, where the local median is 25 and the top-10% bar is 56, this score is mid-pack rather than exceptional — typical of its market rather than a standout.
Overall, Los Altos High School's UC Reach is higher than 25% of California high schools (1107 ranked).

UC Outcomes Trend — 2018–2025
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.
