Where this district is the answer, and where it is not

The ZIP Code areas it reaches
The spread is the thing to notice. In 01226 this district holds 100% of the homes; in 01201 it holds 1 home, under half a percent. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

What one name misses where high school is arranged elsewhere
Central Berkshire is the largest district in 5 ZIP Code areas. Answer with its name alone and the answer misses 51 of the 7,385 homes those areas hold — though in 3 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.
Central Berkshire holds 535 of the 582 homes in ZIP Code 01026 · Cummington, Massachusetts, so its name is right for most of the area and wrong for the rest: 45 homes with Mohawk Trail School District and Worthington and 2 homes in a district too small to name here.
ZIP Code 01223 · Becket, Massachusetts is a two-district area: 1,956 of its 1,960 homes are inside Central Berkshire, and the other 4 homes are in a district too small to name here. Which one an address belongs to is settled by the street, not by the five digits.
In ZIP Code 01226 · Dalton, Massachusetts the single-name answer is the true one: Central Berkshire holds all 2,927 homes counted there, and no other district holds a share worth naming.
ZIP Code 01235 · Peru, Massachusetts is another area where one name covers everything — 1,542 homes, all of them inside Central Berkshire.
Central Berkshire reaches into ZIP Code 01070 · Plainfield, Massachusetts with 39 of its 349 homes, behind Mohawk Trail School District. The familiar answer for that area is the other name, and it is wrong for those 39 homes.
Who takes the other homes in its ZIP Codes
Central Berkshire runs pre-K through grade 12 itself, so an address it holds sees no change of authority between grade school and high school. The districts listed below are the ones that take the other homes in the ZIP Code areas it shares — Pittsfield School District, Lenox and Worthington. They are neighbors on the same postal ground, not the next stop for its own students.

Where this district sits
What to do next
Ask the district office to confirm your street address. A district settles that question on its own site: look for a school locator, a find my school tool, or an attendance zone map. Where there is none, ask the office itself.
A ZIP Code is a set of mail delivery routes, not a boundary: in 2 of the 9 ZIP Code areas Central Berkshire reaches, at least one other district holds a real share of the homes as well, and the line between them runs along streets. Only the district can say which side of that line an address is on.
This site links to no district website. None of the federal files it is built from publishes one, and a guessed address is worse than none. It is the district office, not a search engine, that settles an address.
If a house purchase depends on the answer, ask the district itself for written confirmation of that exact address. A listing is not a district record, and neither is this page.
What this cannot tell you
The homes were counted in the 2020 Census and the district lines are the 2026 boundary file. Nothing on this page adjusts one to the other. Where houses have been built or cleared since the count, a share here describes the place as it was counted rather than as it stands today, and in the fastest-growing ZIP Code areas that gap is the largest single source of error on this site.
A share on this page is a share of the homes in the ZIP Code area, not a probability for any particular address. Enrollment is decided by street address, and a district may run magnet, charter or choice programs that ignore the boundary entirely. If a decision depends on the answer, the district office is the only authority; this page shows what the federal boundary files say and when they were published.
A district boundary is not a school attendance zone. This site never says which school an address is assigned to: no current national dataset of attendance zones exists, and the district draws them itself. Nor is anything here endorsed or certified by the Census Bureau; we use their published files, and that is the whole of the relationship.
A ZIP Code is a set of mail delivery routes, not an area. What is mapped here is the Census Bureau's ZIP Code Tabulation Area, the closest published approximation to it. The two are not identical, and a handful of ZIP Codes used only for post office boxes or single buildings have no tabulation area at all.
Where these numbers come from
School district boundaries come from the Census Bureau's Census Geographic Relationship File, current 2026 vintage, which assigns every census block to a unified district or to an elementary and a secondary district. Homes and residents in each block come from the 2020 Census Redistricting Data (PL 94-171), H1_001 and P1_001. The ZIP Code areas come from the same Geographic Relationship File, block to ZIP Code Tabulation Area. District names and grade ranges come from the Census Gazetteer 2025, with 2020 for districts no longer listed.
The place name printed beside a ZIP Code comes from the Census 2020 ZIP Code Tabulation Area relationship files: place, county subdivision and county, taken 2026-09-06. It is a label rather than a measurement: the Census Bureau does not publish which post office a ZIP Code belongs to, so the place named is the one covering the most land inside the area, not the city the Postal Service prints on an envelope.
Everything else on this page — the shares, the counts of districts per ZIP, the comparison between the two grade bands, the rankings — is computed here from those files. The source publishes none of it. Snapshot taken 2026-09-03.
