What the 1 km column is and isn’t

Living inside a school’s 1 km ring puts you in the top distance band when a registration phase is oversubscribed — Citizens within 1 km are admitted first, then Citizens 1–2 km, then Citizens beyond 2 km, then Permanent Residents in the same order. It does nothing at a school that isn’t oversubscribed, and it never outranks citizenship. How balloting works →

River Valley Primary School has the largest HDB catchment here — 35 scored blocks inside 1 km — while Anglo-Chinese School (Junior) has 2. A small number usually means private housing, landed estate, water or industry inside the ring rather than a remote school.

Blocks inside the most 1 km rings

A block inside several schools’ 1 km rings gives you top-band distance priority at several schools at once — so if one ballots out of reach, the next is still a realistic Phase 2C registration. This is a housing signal, not an admissions one: it widens your options, it does not raise your odds at any single school. The best-covered block here sits inside 2 rings.

Ranked by how many of Central’s primary schools have the block within 1 km, then by the block’s young-family liveability score. Distances are measured from the school’s point location to the block, which approximates but does not replicate MOE’s boundary-to-building measurement — check any borderline block on MOE’s SchoolFinder.

Before you plan around a Central school

Distance only decides anything after the earlier phases have taken their places. Work down the ladder and register in the earliest phase you qualify for — a sibling in the school (Phase 1) beats an alumni tie (Phase 2A), which beats 40 volunteer hours (Phase 2B), which beats the open phase (Phase 2C, where 40 places per school are reserved). The 2026 windows and results dates are on the key-dates page.

Frequently asked questions

How many primary schools are there in Central?
3 primary schools in Central appear in MOE's school directory: Anglo-Chinese School (Junior), River Valley Primary School, St. Margaret'S School (Primary).
Which HDB blocks in Central are within 1 km of a primary school?
55 scored HDB blocks in Central sit inside at least one primary school's 1 km ring, and 2 of the blocks listed here sit inside more than one (snapshot 2026-11). Distance priority only applies when a phase is oversubscribed.
Does living in Central within 1 km of a school guarantee a Primary 1 place?
No. Home-school distance is a tiebreaker used when a phase has more applicants than places. Singapore Citizens are admitted ahead of Permanent Residents in every distance band, and the ballot runs only in the band where places run out.
