Key points
- Start from the district calendar and its registration rule: some districts register only once you live in the home, and Boston runs priority rounds in January.
- A closing or lease start date that slips can push registration past the first day. Build in a cushion and agree a backup plan.
- A current lease is accepted proof of residency in many districts, so renting first can work if the lease is for the home you actually live in.
- A student may enroll where the family actually lives at any point in the year. Records can follow from the old school, and moves inside a town have their own rules.
Work backward from the district’s rules
Pick the target school year and grade, then find three things on the district’s website: the first day of school, when registration opens, and when the district will process a registration. Lexington, for example, lets families begin once they have occupancy of their Lexington home. Newton has no registration deadline but recommended registering kindergarten students by March 20, 2026 for the 2026-2027 year, with buffer-zone placements announced around April 10. Boston’s priority window for entry grades runs in January and early February.
Then lay the housing timeline beside it. The question is simple: on what date will you have the document the district accepts, and is that early enough?
Buying: closing date versus the first day of school
A purchase has several dated steps after an accepted offer: inspection, the purchase and sale agreement, the mortgage commitment and the closing. Any of them can move. If the student needs to start on the first day, aim to close with a cushion before it and talk with your attorney about what happens if the closing is delayed.
From our work with buyers, spring and early summer are often the busiest months for those who want to move before September, so homes in that window can draw more competition. Buyers without a school-year deadline sometimes find a calmer pace after Labor Day. Neither season changes the district’s rules.
Do not register using a home you have not yet closed on unless the district has told you in writing that it accepts that document. Brookline, for example, lists a settlement statement with payment, a mortgage payment or a property tax bill as proof of residency, all of which follow the closing.
Renting first
Renting for a year can give a family time to learn an area while the student starts school on schedule. Many districts accept a lease: Brookline lists an active lease as proof of residency, with two recent bills in the parent’s or guardian’s name as proof of occupancy, and Boston accepts a current lease or a BPS Landlord Affidavit as one of its two proofs.
The lease has to reflect where you actually live. Brookline does not accept a temporary residence of four weeks or less, and Lexington does not treat a temporary residence held only for school attendance as residency. Check the address with the district before you sign. In Greater Boston many leases start September 1, so compare that date with the district’s first day and registration rules; our renting timeline guide covers the leasing calendar.
Moving during the school year
The right to attend the schools of the town where you actually reside, under M.G.L. c.76 §5, does not depend on the time of year. After a mid-year move into a new town, register promptly with the new district. The new school may obtain the student’s record from the old one when the old school has given notice that it forwards records (603 CMR 23.07(4)(g)); bring report cards and any IEP or 504 plan anyway.
A move within the same town can change the assigned school. Newton requires families to update their address after any move within the city, and a family that wants the student to stay at the current school must file a Continuation in Placement request. Ask your district what applies before you sign.
A planning sequence
Every family’s dates differ, so treat this as a checklist rather than a rule. Our relocation guide covers the wider move.
| When | What to do |
|---|---|
| As soon as a move is likely | Note the target school year and grade; read the registration pages of the districts you are considering; for Boston, note the January priority window |
| Before touring seriously | Lender pre-approval or rental budget; list the documents each district accepts |
| Before signing a P&S or lease | Check the exact address with the district in writing; ask your attorney about dates; agree a backup plan |
| When you have the qualifying document | Register, submit health records and the language survey, and request records from the previous school |
| Before the first day | Confirm the school assignment, transportation and start time with the district |
General information about Massachusetts public school rules, current as of the date shown. School assignment is decided and confirmed only by the school district. No listing, seller, landlord or real estate agent can guarantee that an address is assigned to a particular school or that a student will be enrolled or admitted anywhere. Confirm with the district’s registration office, and ask an attorney about contract questions.
