🏫 School Analysis — Menlo Park Area

This analysis covers 20+ schools across 4 categories: elite private (6-12), smaller private/alternative (K-8), public (MPCSD & Las Lomitas), and the destination high school (M-A). Every claim is sourced. Where data is unavailable, that absence is noted — a school's refusal to publish outcome data tells you something.

The Three Questions Nobody Answers

School brochures give you test scores, teacher ratios, and campus photos. They never answer the three questions that actually matter for a rational decision:

💰 1. What's the real cost? (It's not tuition.)

Private school tuition is capital that could be compounding in the S&P 500. Nueva K-12 costs $669K in tuition but $3.28 million in foregone market returns by age 28. Even a 7-year stint at Menlo School ($65K/yr) represents $1.87M in opportunity cost. Sacred Heart at $47K/yr is the "cheapest" elite private — still $1.38M foregone. Meanwhile, MPCSD public schools cost $0 in tuition, score 75-84% on CAASPP math (vs 34% state avg), and La Entrada (Las Lomitas) at 83% math proficiency outperforms every MPCSD school.

🎓 2. Do expensive schools actually send more kids to better colleges?

The uncomfortable answer: not obviously. CDE College-Going Rate data shows public Carlmont High sends 18.8% of graduates to UC (109 of 580) — a higher rate than the self-reported numbers from most private schools. Palo Alto High: 16.2%. Gunn: 14.1% with the highest overall college-going rate (91.2%). Private schools don't report to CDE, so we're comparing their polished marketing claims against audited public data. Menlo School claims 30 Stanford admits over 3 years. Harker's 1514 avg SAT and ~10% HYPSM rate is the strongest on paper. But Carlmont does it for free. Full analysis →

☠️ 3. What does the commute actually cost in safety?

Nobody includes commute mortality risk in school evaluations. They should. Using county-specific FARS fatality data: Harker accumulates 110.9 micromorts per year (a micromort = 1-in-a-million chance of death). Over K-12, that's a 1-in-900 chance of a fatal accident just driving to school — equivalent to 158 skydiving jumps or smoking 792 cigarettes. Harker's rate is 65× higher than Menlo School (1.7 µMort/yr) because US-101 through Santa Clara County is the 3rd deadliest highway stretch in the US. The route matters more than the distance: GISSV via 101 accumulates nearly 4× the risk of Nueva via I-280, despite only 25% more distance. Local schools (Menlo School, Sacred Heart, MPCSD) are effectively zero risk — the equivalent of 6-9 cigarettes over 7 years. Full analysis →

Traditional Findings

• For math-obsessed kids: Nueva (USAMO/IMO winners, math through Complex Analysis) and Harker (MATHCOUNTS champions, AMC/AIME pipeline) are in a different league. Everyone else offers "honors tracks" but not competition-level acceleration.
• For college placement: Menlo School publishes the most transparent data — 30 students to Stanford over 3 years. Castilleja's 51-student class punches way above its weight. Harker's 1514 avg SAT and ~10% HYPSM rate is the strongest on paper.
• For value: MPCSD public schools at $0 tuition with $27K/student in public spending. La Entrada (Las Lomitas) at 83% math proficiency is the public standout.
• For affordability in private: Notre Dame Belmont ($32K) is the best value among college-prep privates — half the cost of elite independents with 19 AP courses and Platinum Honor Roll status. Sacred Heart ($47K) and Crystal Springs (~$65K) are cheapest among elite privates. Catholic parish schools (Nativity) are ~$10-16K.
• The AP question: Castilleja, Menlo, Nueva, and Crystal Springs have all abandoned AP. Only Sacred Heart (28 AP courses), Harker (27 AP), and Notre Dame Belmont (19 AP, Platinum Honor Roll) still run traditional AP programs. This is a national trend among elite independents.

Notable alumni: Lindsey Buckingham & Stevie Nicks (Fleetwood Mac), Bob Weir (Grateful Dead), Ruth Porat (Alphabet CFO), Troy Franklin (NFL).

Recent Issues

• November 2022: Two separate gun incidents — students brought loaded firearms to school. Delayed parent notification criticized.
• November 2023: Israel-Palestine lesson controversy — lesson included material called Turkish propaganda, prompted heated board meeting and public records requests.
• Achievement gap: Significant gap between White/Asian and Hispanic/Pacific Islander students reflects the diverse catchment.

This is the question that separates schools most clearly. "How do you handle a kid who's ahead in math?" reveals more about a school's philosophy than any marketing materials.

College Matriculation Transparency Ranking

One of the most revealing metrics is which schools publish their data vs. which hide it. Schools that don't publish placement data are telling you something — either their outcomes don't match their tuition, or they've decided transparency isn't in their interest.

Standardized Test Comparisons

Note on Nueva's generosity: Free tuition for families under $150K. Families $150-250K pay 1-10% of income. This effectively makes Nueva accessible to a wider socioeconomic range than its sticker price suggests. Source

Private school tuition is not just a yearly expense. It's capital that could be compounding in the market. This section calculates the opportunity cost of private school tuition invested in an S&P 500 index fund instead, at two milestones: high school graduation (age 18) and age 28 (when early career outcomes are measurable).

This is not an argument against private school. Education returns are real but hard to quantify. This is the financial cost you're implicitly paying on top of tuition — the growth your money would have earned.

Assumptions

• S&P 500 return: 10.5% nominal annual (1957-2025 historical average, including dividends reinvested)
• Public school cost: $0 incremental tuition (property taxes fund it regardless)
• Contributions: Tuition amount invested at the start of each school year
• After school ends: No new contributions; existing balance continues compounding
• Pre-tax: Capital gains taxes would reduce these numbers (~15-20% federal LTCG). However, a 529 or UTMA account structure could shelter some or all gains.
• No tuition increases: Using current tuition held flat (conservative — tuition typically rises 3-5%/year, which would make these numbers higher)

The headline numbers are sobering. Sending a child to Nueva from 3rd grade through 12th means foregoing $3.3 million in potential market returns by the time they turn 28. That's not a tuition bill — it's a trust fund. Castilleja at $1.8M and Menlo at $1.9M aren't far behind.

But the numbers need context:

• 10.5% is the long-run average, not a guarantee. The S&P returned -37% in 2008 and +29% in 2019. Actual returns depend heavily on the specific decade. A 7% inflation-adjusted return gives roughly 60% of these figures.
• Taxes erode the gains. Long-term capital gains at 15-20% federal (plus ~13% CA state) would reduce the final number significantly. A 529 plan or UTMA account can shelter some of this, but with restrictions.
• Education returns are real but unmeasurable. If private school gets your child into a better college, better network, better career trajectory — that has compounding returns too. The Raj Chetty mobility data shows elite college attendance has a measurable income premium, but it's entangled with selection effects (kids who get into elite colleges may have succeeded regardless).
• The K-8 schools are the value play. Nativity at $13K/year or Peninsula at $36K/year for 3-6 years gives the differentiated elementary experience, then free public high school at M-A (which sends plenty of kids to UCs and Stanford). The opportunity cost is $454K-$1.2M instead of $1.8M-$3.3M.
• The real question: Is the marginal educational benefit of Nueva over MPCSD public schools worth $3.3M to your child at age 28? That's the question this table forces you to ask honestly.

Formula: Future Value of Annuity Due. Each year's tuition is invested at the start of the school year at 10.5% annual return. After the final school year, the balance compounds without additional contributions through age 28. FV = Σ[PMT × (1.105)^(n-i)] for i=1 to n, then × (1.105)^{(years remaining to age 28)}.

The Data Exists — And It's Public

Contrary to what most school guides claim, the University of California does publish per-school admissions data. The UC Information Center's "Admissions by Source School" dashboard shows applicants, admits, and enrollees from every high school in California — going back nearly 30 years. The UC Accountability Report (2025) provides systemwide context. The data is public. We also obtained actual UC enrollment data from the California Department of Education's College-Going Rate files, which tracks where every public school graduate actually enrolls.

UC Systemwide Admit Rates (Fall 2024)

Before looking at individual schools, here's the system-wide context from the UC Accountability data tables:

Source: UC Accountability Report 2025, Chapter 1 data tables. California resident admit rate: 70.1% overall.

Real UC Enrollment Data: Public Schools (CDE, 2022-23)

This is not self-reported. This is the California Department of Education tracking actual enrollment at UC campuses within 16 months of graduation. Source: CDE College-Going Rate files.

Source: CDE College-Going Rate, 16-month post-completion, AY 2022-23. "CCC" = California Community Colleges. "OOS 4yr" = Out-of-state four-year colleges. CDE only tracks public schools; private schools are not included in this dataset.

UC Enrollment Trends (2014-2023, CDE Data)

Nine years of real data shows which schools consistently send students to UC:

Key insight: Palo Alto High and Gunn have low UC rates (14-16%) not because students don't get in, but because 43-47% of graduates go to out-of-state four-year colleges. Their families choose private/OOS over UC. At M-A, 27% go to community college first. Very different populations making very different choices with very different resources.

Private School Comparison (Self-Reported)

Private schools don't appear in CDE data. We're stuck with what they choose to publish:

The uncomfortable comparison: Free public Carlmont High sends 18.8% of graduates to UC. Menlo School ($65K/yr) sends 11.4%. Menlo's students go to Stanford and Ivy League instead — but if UC enrollment is your metric, the public school wins outright.

Menlo School Deep Dive (Classes of 2023-2025)

Menlo is the only local school that publishes detailed-enough data for real analysis. From their 2025-26 School Profile PDF:

• 429 graduates over 3 years, 49 matriculated to a UC (11.4%)
• Stanford alone (30) outpaces all UC campuses combined (49)
• UC Berkeley + UCLA rate: 6.5% of graduates — lower than the Stanford rate (7.0%), remarkable given Stanford admits ~4% of applicants vs Berkeley at 11%
• Menlo students overwhelmingly prefer private universities. The top 5 destinations by count: Stanford (30), UChicago (17), Boston College (12), Tulane (11), WashU (11)
• MIT (3), Yale (3), Princeton (4), Columbia (2) — Ivy+ numbers are solid but not dominant for a $65K/year school

Castilleja: What We Know (Class of 2025)

From the Castilleja School Profile 2025-26:

• 51 graduates, median unweighted GPA 3.96, weighted 4.14
• Students admitted to all 9 UC campuses — but Castilleja doesn't publish counts per school
• Bold-type schools (indicating enrollment, not just admission): includes Stanford, Harvard, MIT, Princeton, Brown, Georgetown, Northwestern, UChicago, among others
• 79% scored 4 or 5 on AP exams; 93% scored 3+
• 15 recruited NCAA athletes placed at schools including Stanford, Columbia, Harvard, MIT, Yale

A micromort is a 1-in-a-million chance of death. It's how risk analysts compare activities that seem incomparable — one skydive (7 µMort), one scuba dive (5 µMort), one day of skiing (0.7 µMort). The concept was developed by Ronald A. Howard at Stanford — fitting, given where these schools are.

Nobody includes commute mortality risk in school evaluations. They should. The numbers below use county-specific fatality rates from SWITRS/FARS data rather than the national average, because the routes matter. The Menlo Park → San Jose commute (US-101 through Santa Clara County) is one of the deadliest stretches of highway in the United States (3rd overall, 78 fatalities 2015-2019). The Menlo Park → Hillsborough route (I-280 through San Mateo County) is significantly safer.

Using California SWITRS data and Caltrans DVMT (Daily Vehicle Miles Traveled) estimates:

Sources: California OTS Quick Stats 2023 (statewide MDR). County fatalities from SWITRS. County DVMT from Caltrans MVMT estimates. US-101 Santa Clara fatalities from ValuePenguin/FARS analysis (78 deaths over 5 years). vehicle-safety.org maintains a complete FARS dataset for per-model analysis.

Key insight: San Mateo and Santa Clara counties are 2-3× safer per mile than the national average — suburban infrastructure, higher incomes (newer cars, more safety features), less impairment. But US-101 specifically is above the national average rate. The corridor your child commutes on matters more than the county average.

Not all miles are equal. The route to each school determines which fatality rate applies:

• US-101: High volume, truck traffic, aggressive merges, 6-8 lanes. Santa Clara County segment is the 3rd deadliest highway stretch in the US. Rate: ~1.4 deaths/100M VMT (above national average). Used by: Harker, GISSV.
• I-280: Often called the "world's most beautiful freeway." Lower volume, no trucks (prohibited in some segments), better sight lines, divided by wide median. Rate: ~0.3-0.4 deaths/100M VMT (estimated from lower fatality counts on this segment). Used by: Crystal Springs, Nueva, Woodside.
• El Camino Real / local arterials: Lower speed (35-45 mph) but higher pedestrian/bicycle conflict, more intersections, more distraction opportunities. Per-mile rate lower than freeway but per-hour rate potentially comparable. Used by: Castilleja, Menlo School, MPCSD schools.

Counter-intuitive: Highway miles are more dangerous per mile but safer per hour than arterial roads (you cover more distance in less exposure time). A 22-mile freeway commute on I-280 may be comparable in risk to a 10-mile stop-and-go arterial commute — but takes less time.

What This Means in Human Terms

• Harker (K-12 via 101): 1,109 accumulated µMort ≈ 1-in-900 chance of a fatal car accident just from the school commute. That's 158 skydiving jumps, 792 cigarettes smoked, or the risk of ~2 tours in Afghanistan (UK military data).
• GISSV (K-6 via 101): 454 µMort in just 6 years — the 101 corridor rate makes even a shorter enrollment period dangerous. Normalized to 7yr: 529 µMort (76 skydives).
• Nueva (K-12 via 280): 202 µMort over 10 years — equivalent to 144 cigarettes. The I-280 route cuts risk dramatically vs a 101 commute of similar distance. Still 29 skydives.
• Crystal Springs (6-12 via 280): 130 µMort. Moderate but manageable — the 280 corridor keeps this from being alarming.
• Menlo School / Sacred Heart (local roads): 12 µMort over 7 years — 2 skydives. Essentially a rounding error.
• MPCSD public schools: 4-18 µMort total — 3-13 cigarettes over the entire enrollment. Walking/biking distance for many families. Approaching zero risk.

Time Cost Compounds the Risk

The micromort calculation only captures mortality risk. It doesn't capture the time cost, which compounds the health impact:

• Harker: ~44 miles RT × 180 days = 7,920 miles/year. At 30 mph average (Bay Area traffic on 101), that's 264 hours/year in the car — 11 full days. Over 10 years: 110 days of your life spent commuting to school.
• Nueva: ~24 miles RT → 144 hours/year → 60 days over 10 years. (280 traffic is lighter, so effective speed is higher — closer to 90 hours/year.)
• Menlo School: ~2 miles RT → 12 hours/year → 3.5 days over 7 years.

Those 110 days at Harker could be spent on sleep, homework, extracurriculars, family time, or literally anything else. This is a real cost that never appears on a school's brochure.

Caveats & Methodology

• County rates are lower than national average. San Mateo (0.47/100M VMT) and Santa Clara (0.56/100M VMT) counties are 2-3× safer than the US average (1.26). This reflects newer vehicles, higher seatbelt compliance, less impaired driving, and better infrastructure. However, US-101 through Santa Clara specifically exceeds the national average (~1.4/100M VMT) due to volume, truck traffic, and design.
• Corridor rates are estimated. FARS doesn't publish fatality rates by specific highway segment × county. We derived the 101 corridor rate from 78 fatalities over 5 years on the Santa Clara segment (ValuePenguin/FARS), divided by estimated segment VMT. The I-280 rate is estimated from its significantly lower fatality count despite comparable length. These are directional, not precise.
• Adjusted driver risk is lower. A seatbelted, sober, attentive driver in a modern car has roughly 1/3 the population average risk — perhaps 1 µMort per 130-250 miles (LessWrong analysis). Our county-specific rates already partially reflect this (Bay Area demographics skew toward safer drivers).
• Teenage drivers face 2-3× the per-mile risk of adult drivers (IIHS). If your child drives themselves to Harker in high school on 101, their personal risk approximately doubles for those years.
• Carpooling and school buses change the per-family calculus but don't eliminate risk — they redistribute it across fewer trips.
• The comparison isn't "don't go to Harker." It's "factor this into the decision alongside everything else." A 1-in-900 risk spread over 10 years is small in absolute terms — but it's not zero, and nobody ever tells you about it.
