01 · The admin gap
$1,900/pupil
Nassau over Montgomery on administration — ~$370M/yr gross. Real, and the redraw's only true prize.
NCES F-33
Nassau runs 56 school districts for ~195,000 students. The fair question: is that patchwork just expensive duplication — and would starting fresh with new boundaries actually save money? Here is the evidence, not the assertion.
To isolate the effect of structure from the effect of wealth, line up similar affluent NYC- and DC-metro suburbs along a fragmentation gradient and read the one metric that is computed identically in every state — administration spending per pupil (NCES: superintendents + boards + central offices). If fragmentation is the waste, the one-district counties should spend far less here. They do:
| County (metro suburb) | Districts | Enrollment | Admin $/pupil | Total $/pupil | Grad |
|---|---|---|---|---|---|
| Montgomery, MD | 1 | 161K | $968 | $19,456 | 89.6% |
| Broward, FL | 1 | 244K | $1,263 | $12,121 | ~87% |
| Fairfax, VA | 1 | 179K | $1,392 | $18,975 | 93.8% |
| Bergen, NJ | ~70 | ~140K | ~$2,082 | $24,074 | ~91% |
| Nassau, NY | 56 | 195K | ~$2,800 | ~$32,700 | 94% |
NCES Common Core of Data / F-33, FY2022-23. Nassau admin = Garden City $2,840 · Uniondale $2,873 · Port Washington $2,677 (tightly clustered; county-weighted average is an estimate). Westchester (~40 districts) totals $32,400/pupil — nearly identical to Nassau. Grad rates: NYSED / state DOEs 2023.1,2
Nassau spends ~2.9× what Montgomery County, MD does per pupil on administration — about $1,900/pupil, ~$370M/year — the real, measurable cost of running 56 superintendents and back-offices instead of one.
So yes: the patchwork is provably wasteful — on the administrative line. That is a genuine ~$370M/year of duplicated overhead, and it is the thing you're sensing. The trap is assuming a boundary redraw captures it. The next three pages show why it mostly doesn't — and what does.
Administration is ~5–10% of any school budget. The other 90% — teachers, benefits, buildings — is where the money is, and consolidation can't touch it.
If the patchwork itself were the cost driver, total per-pupil would fall as districts consolidate. It doesn't. Nassau (56 districts) and Westchester (40) spend almost the same — $32.7K vs $32.4K. Among the consolidated counties, Broward ($12.1K) and Fairfax ($19.0K) differ by 1.6× — driven entirely by region and labor cost, not structure. Long Island instruction runs $19,000–$25,000/pupil (Garden City $19,181, Uniondale $24,909) vs Montgomery's $13,211. That instructional gap alone dwarfs the entire admin line. Cost-of-living and union labor — not the number of districts — set the bill.
The defensible prize is the ~$1,900/pupil of duplicated administration — fewer superintendents, boards, HR/payroll/IT/purchasing offices. It is real and worth pursuing. But it is a thin slice, and — as page 3 shows — a boundary redraw is a remarkably inefficient way to capture even that slice.
School-district savings follow a U-curve: huge for merging tiny districts, ~zero once past ~1,500–2,000 pupils. Nassau's districts already average ~3,700 — they are past it.
Doubling a 300-pupil district saves ~23% net (Duncombe & Yinger, 12 actual NY mergers); at 1,500 pupils it's ~3%; above that, "little if any." The optimal band is 2,000–4,000 pupils — Nassau's average sits inside it. A single ~195,000-student county district would overshoot the cost-minimizing point ~30× into diseconomy (extra management layers, county-wide busing, slower procurement). And the gross admin prize is then eaten from three sides:
On merger, salaries and benefits harmonize to the most generous contract, permanently. Plausibly consumes 30–60% of gross admin savings — and Long Island is the highest-wage environment in the country.
Nassau's 56 districts already bank some scale through BOCES shared services (36–90% state aid). A single county district is too large to be a BOCES component — it forfeits the very subsidy that funds those economies.
56-system integration, contract harmonization, severance, facility equalization — front-loaded; net cash flow is negative for years. NY's 40% merger-incentive aid rides on Foundation Aid, which is structurally tiny for wealthy Nassau — the carrot is weakest exactly here.
| Scenario | Net recurring saving (after offsets) | Transition cost · payback | Risk | Legal / political path |
|---|---|---|---|---|
| (a) One county-wide district Montgomery-MD style, ~195K | ~1–3% · $185–560/hh diseconomy bites hardest | Very high · 7–12 yrs | Very high | None short of state law (can't win 56 referenda) |
| (b) Three town-based districts Hempstead / N. Hempstead / Oyster Bay | ~1.5–3.5% · $280–650/hh best raw net | High · 5–9 yrs | High | Referenda or legislation |
| (c) Virtual consolidation keep 56; mandate shared back-office via BOCES | ~1.5–2.5% · $280–465/hh almost no offsets | Low–moderate · 2–4 yrs | Low | Exists — BOCES + CWSSI frameworks already in place |
Net-of-offset $/household are estimates over ~430K Nassau households; gross admin prize ~2–6% of the ~$8B operating base. Scenario (c) keeps boards, brand, and BOCES aid — capturing most of the addressable economy at a fraction of the cost and risk.3
The model says modest-and-eaten. The real-world record is worse: large mergers don't deliver the savings, and the live political force runs the other way.
The largest US school merger — booked no real savings, stranded a $1B+ retiree-health liability on the poorest students, then fractured in ~14 months when six wealthy suburbs seceded. By 2026 the remnant is under state takeover. Secession is the predictable elite response to a forced merger.
An Ernst & Young study projected ~$23M/yr in savings, ~400 jobs cut. Independent review afterward: no savings, little real duplication; metro spending ran at or above the pre-merger totals.
Looked tidy only by excluding schools and welfare — and a federal judge later ruled it intentionally discriminated against Black students by extending government to the county line while leaving 11 near-all-white suburban districts intact. ~55% of officials doubted it cut costs.
NY's 10,000→700 district centralization worked — but only for tiny districts, and it stalled before it reached suburban Long Island. Every LI merger since has failed (Tuckahoe–Southampton 2013 & 2014; Elwood 2010–11; Johnsburg–Minerva 2024) — the low-tax / high-home-value district always votes No. The live national trend is secession, not merger: 73+ wealthier enclaves have split off since 2000 (EdBuild).
The patchwork isn't efficient — but redrawing the map is the wrong cure for the one thing it gets wrong.
The waste is real and narrow: ~$1,900/pupil of duplicated administration. A boundary redraw overshoots Nassau's already-optimal district size into diseconomy, has a third-to-half of its prize eaten by union leveling-up and lost BOCES aid, carries severe risk (top-district home-value hits, Memphis-style secession, stranded liabilities, lost local control), and has never once passed on Long Island. What captures most of the same prize — ~$120–200M/yr, fast payback, a legal path, boards left in place — is virtual consolidation: mandated shared back-office through BOCES. Don't redraw the lines to save money — empty the duplicated offices behind them. But money was never the whole question. The one prize a redraw buys that shared services can't is a single political voice — turn the page.

The cost frame misses something real: 56 superintendents dilute education to a local issue, while one superintendent for ~196,000 students would be a peer at the governing table. Half of that is true.
It is the one prize a boundary redraw buys that shared back-office (scenario c) cannot. A unified Nassau district would be the ~6th-largest in the United States — bigger than Boston, DC, or Atlanta. And the political-science evidence confirms the seat is real: a single mega-leader is a named official who lobbies the capital in person, whose governance is itself a recurring legislative bill (New York City's mayoral-control renewals), and who can sue the state and move the entire funding formula — NYC's CFE suit forced a $5.5B statewide Foundation Aid increase. Fragmented districts can only do this by aggregating into associations, which forfeits the single accountable name.
Across NYC, Miami-Dade, Broward, and Clark County, scale buys visibility and accountability — not more money per child. Big districts get frozen political quotas (NYC's 38.86% / Long Island's 12.96% "shares" deal) and perennial "we subsidize the state" grievances; small districts often get more per pupil (California: under-100-student districts get ~2× the rate); federal dollars track poverty, not governance. A unified Nassau would also partly duplicate the Long Island delegation that already wins the regional fights — it beat the Governor on "save-harmless" aid in 2024. And the seat has a price: the biggest systems re-fragment internally to claw back responsiveness (Nevada broke Clark County into 200+ "precincts"; Hawaii has debated breakup since 1977), with mega-procurement failures (LAUSD's $1.3B iPad collapse) and board-capture spending arms races.
Scale buys the seat, not a bigger slice off it. A unified Nassau super would get to argue as a peer — the evidence does not show they'd win more per child for it.
"What could the Locust Valley superintendent achieve speaking for the whole county?" is the wrong question — because under unification they would no longer be speaking for Locust Valley.
A countywide superintendent answers to the county's median and largest enrollments — Hempstead, Uniondale, Freeport, Roosevelt (high-need, ~93% Black/Latino, averaging ~$10,000 less revenue per student) plus the broad middle. Locust Valley is ~1,800 students — about 0.9% of the county — spending ~$55,000/pupil it fully controls today. Under unification it would trade 100% control of its own board and budget for a <1% minority share of a voice aimed at a poorer median — a voice that would likely redistribute away from its premium. That is not amplification; it is subordination. Which is exactly why wealthy districts and their legislators fight consolidation.
Nassau's aggregated education voice already exists — and already serves the affluent. Long Island's high-need, majority-minority districts received as little as 1% of one year's aid increase, and under 4% of the Foundation Aid they were owed — despite the Long Island Senate Majority Leader AND the Senate Education Chair both being from Long Island (Alliance for Quality Education, 2017). And in 2024 Nassau's own superintendents' council used its collective voice to kill state regionalization and protect the 56-district structure (the "Our Schools, Our Rules Act"). When Nassau's education voice does speak as one, it speaks to defend fragmentation.
For the high-need student, fragmentation dilutes their voice and a unified super would amplify it — the dilution thesis is true. For the wealthy small district, fragmentation IS maximal voice (total local control) and a unified super would dilute it to under 1% — the thesis inverts. There is no single "education's voice" in a county this economically stratified. That is the deepest reason the 56 districts have never merged.
The voice argument is the best case for real consolidation — but it's a case for the high-need districts and the county, not for Rockville Centre or Locust Valley.
On cost, a redraw overshoots into diseconomy and gets eaten by offsets (pages 1–4). On voice, it buys a real seat — but not a bigger slice, and not your seat. For a wealthy district the two axes point the same way: a redraw trades control you already have for a minority share of something aimed elsewhere. If the goal is countywide equity, the unified voice is a genuine prize — the same lever as the desegregation brief. If the goal is RVC's bill and RVC's control, it was never yours to win. The honest move holds: shared back-office for the savings; keep your local voice; pursue the unified voice only as an advocate for the county's median child — not against them.
