Within 1km
142 blocks
13,684 flats in total
Between 1km and 2km
68 blocks
4,971 flats in total
Before you rely on a band
HDB blocks only. This list covers HDB blocks. Condos and landed homes near the school are not included yet, so a home that is not listed here is not necessarily outside a band.
Band edges. Treat any block within about 200m of a band line as close enough that MOE could call it either way, not as settled. Confirm your own address on SLA's OneMap School Query, the service MOE tells parents to check in the year of registration.

Within 1km: 142 blocks, 13,684 flats

These blocks are within 1km of the school on the measurement basis MOE uses, the band that comes first in the distance priority.
