Why a range, not one number. No record shows your floor, facing, renovation or lease, and where your unit sits inside this spread depends on them.

How this distance differs from MOE's

MOE measures in a straight line to the school's land boundary from the address on your child's registration. This site measures from the block to the school's single registered coordinate. A large campus can therefore read as further away here, and a school near the line can fall on either side when MOE measures it. An oversubscribed school still ballots within a band.

Three things this can't know

Your actual floor, facing and renovationPublic data gives a storey band, never your unit.
Whether you sell or buy firstChanges your ABSD, timeline and bridging cost — often by five figures.
Your real CPF accrued interestThe figure here is an estimate. Yours is in your CPF statement right now.

Tell me those and I'll run your actual numbers — no charge, no obligation.

Name

Your floor or stack

Optional — but it's the single biggest thing the public data can't see.

Leaving it unticked is fine — the tools work either way, and I'll still reply to this enquiry. I don't sell or share your details.
