🎓 Academic rigor
AP + advanced-course offerings
Moderate — some AP / advanced course access
Bottom 44% of US high schools
Source: federal Civil Rights Data Collection (CRDC 2020-21). CRDC reports what's offered + enrolled — it doesn't collect AP exam pass rates (College Board owns that data and doesn't release it school-level).
SAT / ACT participation
CRDC federal data · 2020-21Source: 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.

🏛️ Federal Title I context
Title I Schoolwide eligible
≥40% FRPL — qualifies for Title I Schoolwide program
40-74% of students qualify for free/reduced lunch. The district can use Title I funds across the whole school under federal Schoolwide Program rules.
Source: NCES Common Core of Data, free/reduced-price lunch eligibility. The actual Title I designation is a district decision and may differ from eligibility — but the federal eligibility math is what we show here. We don't claim to assert whether the district formally chose to enroll this school in Title I.

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.

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 down 10.0 pp since 2016-17. Engagement improving — a positive trajectory worth understanding and reinforcing.

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.
Enrollment growth is beating Los Angeles County (+0.0% vs. -12.1%), but 32 of 56 students didn't maintain continuous enrollment. Why are families leaving once enrolled?
32 of 56 students who enrolled at Mountain Park School this year didn't maintain continuous enrollment (57.1% 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.
