Primary 1 registration in Bishan

Primary schools in Bishan

Catholic High School has the largest HDB catchment here — 80 scored blocks inside 1 km — while Ai Tong School has 47. 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 Bishan’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 Bishan 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.
