🎓 Academic rigor
AP + advanced-course offerings
Strong — solid AP program + advanced courses
64th percentile nationally
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 · 2020-21Bottom 29% by test-taker volume
Source: 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.
🎓 4-year graduation rate · federal EDFacts
What % of students graduate on time?
90th percentile nationally

🏛️ Federal Title I context
Mixed-income school
Below Title I eligibility threshold (FRPL < 35%)
25-34% of students qualify for free/reduced lunch. Below the federal Title I threshold but a meaningful share of the population is income-eligible for free lunch.
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.
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 5.8 pp since 2016-17. A rising absenteeism trend often precedes formal departure — worth investigating which subgroups are driving it.

UC Reach Score = top-6 UC admits ÷ senior class (can exceed 100 when students are admitted to multiple campuses). Enrollment trend = first-to-latest grade-12 change on file. Similar schools matched on proximity, size, type. Methodology →
Enrollment stability & demand — 2024-25
Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the Solano County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Buckingham Collegiate Charter outperformed Solano County on enrollment (school +16.5% vs. county -6.4%) AND maintains 94.4% stability. Replicable model — worth documenting what's working.
27 of 485 students who enrolled at Buckingham Collegiate Charter this year didn't maintain continuous enrollment (5.6% 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.
