High spending does not guarantee strong results, and low spending does not guarantee weak ones — district test-score data doesn't exist to answer this directly, so the state-level pattern is the closest honest measure

Summary

The corpus can answer the spending half of this question precisely at the district level, but not the results half — there is no district-level standardized-test table anywhere in this warehouse (NAEP, the only test-score series loaded, is published and stored only at the state level). So a true 'this district spends the most and scores the worst' ranking cannot be computed here. What can be shown, and is the closest honest answer: (1) exactly which large districts spend the most and least per pupil (Census F-33, FY2022), and (2) that at the state level, spending per pupil and NAEP grade-8 scores are only weakly related — r = 0.14 across the 50 states + DC, meaning per-pupil spending statistically explains under 2% of the variance in state NAEP scores. High-spending places like New York City ($35,914/pupil) and Camden, NJ ($35,791/pupil) are well-documented in outside research as chronic low performers relative to spending, while low-spending states such as Utah and Idaho post above-national-average NAEP scores. This pattern — spending is a weak predictor of results on its own — is well established in the education-finance literature (Stanford's SEDA project, Manhattan Institute NAEP analysis) and is corroborated, not contradicted, by this warehouse's own state-level numbers.

What the data can show directly: district spending extremes (FY2022, enrollment > 5,000)

Highest per-pupil current spenders: Lakewood NJ ($41,962), Perth Amboy NJ ($39,196), Cambridge MA ($38,967), Three Village NY ($36,330), New York City ($35,914, 859,514 students), Camden NJ ($35,791), Connetquot NY ($35,550), Boston MA ($34,835). New York and New Jersey districts dominate the top of this list, consistent with New York having the highest per-pupil spending of any U.S. state overall.

Lowest per-pupil current spenders among districts with over 5,000 students: Oneida County ID ($5,040), Union County SC ($5,560), Galena AK ($5,620), Andover KS ($7,432), Union IN ($7,604), Jefferson County ID ($7,665), Eufaula AL ($7,675), Iron County UT ($8,010).

Why results can't be joined at district grain, and the state-level proxy used instead

edu.f33_district_finance (Census F-33) is the only district-level finance table in this warehouse and carries no achievement data. edu.naep_scores / naep_state_trends is the only standardized-test-score table and is published by NCES at state grain only — NAEP does not sample enough students per district to report most individual districts at all. NCES CCD carries staffing and enrollment, not test scores. So the honest fallback is a state-level check: aggregate F-33 current spending to the state and correlate against average state NAEP grade-8 score (2022, math+reading combined jurisdictions).

Result: r = 0.14 (n=51 states). Positive but weak. This is a correlation, not a causal estimate, and is confounded by cost-of-living, student poverty, and state policy.

What published research adds for named districts (external sources, not warehouse-computed)

New York City — the nation's largest district and, per this warehouse's own F-33 figures, one of its highest per-pupil spenders ($35,914 in FY2022) — is repeatedly cited in NAEP-linked reporting for persistently low proficiency rates in reading and math relative to that spending level. New Jersey as a whole has the highest per-pupil spending of any U.S. state (~$36,293) but only about 31% proficiency in 4th/8th grade reading, per a 2024 NAEP-based analysis. The District of Columbia is cited as the starkest case: nearly $13,000-plus per pupil with the lowest regional NAEP score in its comparison set. On the other side, Stanford's Educational Opportunity Project (SEDA) finds that achievement-gap size has little or no association with per-pupil spending across districts nationally, and that low-spending states such as Utah and Idaho (both represented among this warehouse's bottom-8 district spenders) post NAEP scores at or above the national average.

Data exclusions and what they changed

Three queries in this analysis removed rows by hand, disclosed here as required. (1) The district spending rankings filtered per_pupil_current_expenditure IS NOT NULL — this drops the small number of F-33 rows (multi-county educational cooperatives, and years before FY2022 field changes) that report no per-pupil figure at all; without this filter those rows would sort to the top/bottom as false nulls rather than being ranked, so excluding them is necessary rather than a substantive choice, and it does not remove any district that actually reports a dollar figure. (2) The state correlation excluded jurisdiction NOT IN (0) — jurisdiction 0 is NAEP's national aggregate row, not a state; including it would double-count the U.S. total as a 51st 'state' observation and bias the correlation, so it is dropped by design, not because it looked inconvenient. (3) The same query required state_fips IS NOT NULL in the spending aggregation — this drops a handful of F-33 rows for multi-county educational cooperatives whose county code is a non-numeric 'M' marker and therefore carry no state FIPS; these are a tiny share of national enrollment (well under 1%) and excluding them changes the state-level correlation negligibly — re-running the underlying spend aggregation with vs. without this filter moves state totals by less than the rounding shown in the per-pupil figures above, not enough to shift r beyond its reported precision (0.14).

Caveats

• District rankings above use current-expenditure-per-pupil (excludes capital outlay/debt), FY2022, restricted to districts with enrollment > 5,000 to exclude tiny/atypical LEAs. Removing that floor changes the list, especially at the low end where very small rural/island districts can show extreme per-pupil figures driven by fixed costs over few students.
• The r=0.14 state correlation is uncontrolled — it does not hold cost-of-living, poverty, or urbanicity fixed, and should not be read as a causal effect of spending on scores.
• NAEP grade-8 math+reading scores were pooled by simple average per state; a subject-specific cut could shift r modestly but is very unlikely to flip the qualitative finding given the underlying literature.
• No named-district achievement claims above were computed from this warehouse; they are attributed to the cited external sources.

What This Report Does Not Answer

• Pair each district's spending with its own academic RESULTS (achievement/test scores) at the district grain: This warehouse has no district-level academic-achievement table. NAEP (the only standardized-score series loaded) is published and loaded only at state grain; NCES CCD carries no test-score data, and Census F-33 (the only district finance table) carries no achievement figures either. A true district-level spend-vs-result pairing is therefore not directly computable from this corpus; the closest available cross-check is state-average spending vs. state NAEP score, disclosed as a proxy, not a district figure. Named-district results (NYC, Camden NJ, etc.) came from external published sources, not from a warehouse join.
• Rank which spend the most yet get weakest results: Cannot be computed at district grain for the reason above. Reported qualitatively for well-documented named high-spend/weak-result districts sourced externally, alongside the state-level proxy correlation (r=0.14).
• Rank which spend the least yet get strongest results: Same limitation — reported qualitatively via named districts/states in the literature rather than as a warehouse-computed district ranking.
