Fairness Index
Sherborn scores 39 on the Fairness Index for all state aid and 73 for discretionary money. Fifty is a fair share.
All state aid
39 / 100223rd of 351 (1 = most above its share)
Rank under other weightings: 154th to 268th.
Weighting-dependent: the range crosses the 45–55 band
Sherborn received less than its share of state aid on three of four measures; its blended score of 39 stays between 32 and 47 under every weighting tested.
Discretionary money only
73 / 10096th of 351 (1 = most above its share)
Rank under other weightings: 82nd to 112th.
Stable high: above 55 under every weighting
Sherborn received more than its share of discretionary money on all four measures; its blended score of 73 stays between 68 and 77 under every weighting tested.
Each bar is one way of defining a fair share: Equal, the same per resident; Need, weighted toward poverty, low income and a thin tax base; Burden, by what each program pays for (road miles, bridges, pupils and so on); Effort, by what residents already pay in property tax relative to their income. The line marks 50. The score is the average of the four. Discretionary money is competitive grants and earmarks that name the town. How the index is built.
State money, FY2017–FY2026
Sherborn’s town government and school districts received $41.7 million in formula aid and $3.1 million in competitive grants over ten years.
Formula aid
$41.7M
$9,422 per resident (198th of 351) · gross
Competitive grants
$3.1M
$708 per resident (112th of 351)
Earmark-account payments
$455,000
$103 per resident (20th of 351)
Each class has its own scale. Bars show dollars paid in each fiscal year.
Formula aid is gross: Chapter 70 as DESE attributes it to the town, and cherry-sheet aid before the state deducts charges such as charter tuition and transit assessments, plus other formula programs as paid. Competitive grants and earmark-account payments are Comptroller payments to the town government and its school districts (stage: paid), the same payees as the Fairness Index. Enacted earmarks and earmark payments are different things: enacted earmarks are budget clauses, counted three ways above; earmark-account payments are Comptroller payments to the town government and its school districts from accounts classified as earmarks, which can include prior-year and statewide-program money. Either can be larger. Shared revenue, pass-through contracts, transfers to state entities and unclassified payments, $4.3M in all, are not shown. Rank 1 is the highest amount per resident among 351.
Formula aid is gross; competitive grants and earmark-account payments are as paid. Other classes, $4.3 million, are not shown.

Local earmarks are counted three ways: clauses that name Sherborn; clauses placed in Sherborn, adding organizations located here; and everything placed, adding state facilities located here. Three ways to count a local earmark.
Placed in the town: 13 clauses in seven of ten budgets; the most recent in FY2026. Every one names Sherborn directly.
| Year | Amount | Budget text (excerpt) | Stage |
|---|---|---|---|
| FY2023 | $100,000 | “the Woodhaven Elderly Housing Complex in the town of Sherborn for replacement windows” | Enacted names the town |
| FY2025 | $50,000 | “water quality and infrastructure improvements in the town of Sherborn” | Enacted names the town |
| FY2023 | $50,000 | “a watershed-based plan for Farm pond in the town of Sherborn” | Enacted names the town |
| FY2020 | $50,000 | “exterior safety improvements to the town hall campus in the town of Sherborn” | Enacted names the town |
| FY2018 | $50,000 | “the Commonwealth Housing Development in Brighton” | Enacted names the town |
Enacted earmarks and earmark payments are different things: enacted earmarks are budget clauses, counted three ways above; earmark-account payments are Comptroller payments to the town government and its school districts from accounts classified as earmarks, which can include prior-year and statewide-program money.

The burden index divides the competitive awards Sherborn received from FY2017 to FY2026 by what it would have received if every program had split its money by its own measure of need: road miles for road programs, crossings for culvert grants, town-owned hazard dams for dam repair, jobs for economic development, residents for libraries. 1.0 is proportional. Sherborn: 0.88. State median: 0.91. Bridges count by replacement cost and condition, not by number, and only bridges the town owns. Ranks run from 1, the most among 351.

State land eligible for PILOT is the Division of Local Services’ count of state-owned acres on which the state pays a payment in lieu of taxes; the payment follows the land’s assessed value, not its acreage, so the per-acre figure is a comparison, not the formula. The state-owned share on the land-area tile above is the MassGIS map of all state-owned open space, a wider count. New growth is the assessed value of new construction and improvements added to the tax base, summed FY2017–FY2025 and divided by 2020–24 residents; taxed at the prior year’s rates, it adds to the levy limit beyond 2.5%.
Costs and the 2½% limit
State aid covered 3.5% of Sherborn’s general-fund spending in FY2025, down from 4.9% in FY2006.
State aid as a share of general-fund spending

Net of state charges, FY2025
3.2%
FY2010: 4.5% · median town 10.0%
State aid is the gross cherry sheet as entered on the tax rate recap; spending is the town’s general-fund expenditures as filed with the Division of Local Services. Net subtracts the charges the state assesses on the same cherry sheet (charter and school-choice tuition, transit, county and other assessments), itemized from FY2010.
Sherborn’s own cherry sheet carries no Chapter 70 for pupils in its regional district; the state paid $1.3 million in FY2025 Chapter 70 to the district on its behalf, outside these figures, while the town’s assessment to the district sits in its spending. For a regional member the share understates state support for school costs.
Gross state aid went from $909,000 in FY2006 to $1.2 million in FY2025, +31.0% in dollars. Consumer prices are the Boston-area CPI-U, up 55.1% over those years; government prices are the federal price index for state and local government purchases, up 74.5%. Fiscal-year averages. Flag: in FY2010, $294,000 of Sherborn’s gross aid was in receipts the itemized cherry sheet does not show, consistent with school-building reimbursements that ended by FY2024 (not verified line by line). Part of the change since FY2006 may be that phase-out.

Health insurance
3 of 9
years it grew faster than allowed levy growth
Nine years at 2.5% add 24.9%. Grown that way from FY2016, Sherborn’s health insurance would have been $1.67 million in FY2025; it was $1.57 million, $100,000 below the path. Its fixed costs would have been $2.93 million in FY2025; it was $3.35 million, $423,000 above the path.
Fixed costs are employee benefits, retirement, insurance and similar costs in the general fund; health insurance comes from a separate DLS report. Allowed levy growth is 2.5% plus new growth, as a share of the prior year’s levy limit; a year counts as squeezed when fixed costs grew by a larger percentage.
Local earmarks against the health-insurance increase
Over the nine budgets, earmarks naming Sherborn came to $436,000, 187.2% of the $233,000 rise in its health insurance.
| Measure | Earmarks | Share of the increase | All towns, pooled |
|---|---|---|---|
| Names the town | $436,000 | 187.2% | 28.2% |
| Placed in the town | $436,000 | 187.2% | 42.3% |
| Everything placed | $436,000 | 187.2% | 45.2% |
An earmark is a one-year appropriation; a health-insurance increase recurs in every later budget. Earmarks are counted on the three measures and are not adjusted for the January 2024 mid-year cuts or the FY2026 hold. All towns: pooled over the towns that reported health insurance in both years. All dollars nominal. Method.

Sherborn runs its own district for some grades and belongs to Dover-Sherborn and Tri County for others; Sherborn accounts for 47% and 1% of their foundation budgets, in that order.
Real figures use the CPI-U, fiscal-year average, in FY2026 dollars. The required contribution is the local share the state sets under the Chapter 70 formula; the share of income divides it per household by the town’s median household income.
Expected and actual
Sherborn received $3.6 million in earmarks placed in the town and competitive grants over ten years, 54% more than the $2.4 million its size, need and institutions predict.
The expectation comes from a statewide model of all 351 municipalities that uses population, road miles, jobs, poverty, income, tax base, school-aid share and the presence of hospitals, colleges and nonprofits. Those factors explain about 55–60% of the differences between towns. The model leaves out many legitimate reasons a town may receive more or less, such as a single large project, so a gap is a starting point for questions, not a finding about anyone’s conduct.
Earmarks here are placed in the town, the second of three measures (enacted); competitive grants are Comptroller payments (paid). Method.
Peers
Sherborn ranks 3rd of 11 on earmark dollars placed in the town per resident among itself and its ten nearest peers.
Peers are the ten municipalities nearest to Sherborn on population, income need and tax-base need. The best and lowest performers are the highest and lowest on earmark dollars placed in the town per resident in the wider class of 30 nearest, the second of three measures.
