How the 1km priority works
  1. 1 Within 1km wins. MOE ranks P1 applicants by straight-line distance from the school — within 1km, then 1–2km, then beyond. Singapore Citizens rank above PRs in each band.
  2. 2 It only bites if the school ballots. At 2025 Phase 2C, Ai Tong School drew about 1.9 applicants per place, so distance decided the ballot.
  3. 3 You must stay 30 months. To use Home-School Distance priority, the family must live at the registered address for at least 30 months from the start of P1 registration.

Distances are straight-line estimates from each block to the school's postal point — indicative only. Confirm the exact figure with MOE's official distance guide.
