A parent's guide
A ballot is simply how a place is decided when a phase has more applicants than vacancies. It is a tie-break, not a test: it is drawn by computer, at random, within a group set by MOE's published priority order. A school that balloted is fuller, not better — and whatever happens in one phase, every eligible child is assured a place in a primary school. This guide explains when a ballot is held, how priority works, and, if it doesn't go your way, exactly what happens next.

When it happens
In any phase from Phase 2A through Phase 2C Supplementary, if the number of applicants in a priority group is greater than the vacancies left for that group, MOE holds a ballot to decide who is admitted. If a phase has enough vacancies for everyone who applied, there is no ballot — all applicants are offered a place. Phase 1 does not ballot.
The ballot is conducted centrally by MOE, by computer. No one at the school runs it, and nothing about the child — not their ability, not the order of anything they did — changes the odds within the group being balloted. It is chance, applied fairly, only at the exact point where places run short.
The priority order
When a phase (2C, for example) is oversubscribed, places are given out in a set order. The ballot only ever happens inside the one group where the vacancies run out.
Citizenship: Singapore Citizens, then Permanent Residents
Singapore Citizen (SC) children are admitted before Permanent Resident (PR) children in the same phase.
Then home-to-school distance, in three bands
Within each citizenship group, priority goes first to children living within 1km of the school, then those between 1km and 2km, then those beyond 2km.
A ballot only in the band where places run out
If every child in a higher-priority group can be admitted, they are. The ballot is held only within the single group where there are more applicants than remaining places. Everyone in the groups above is already in; the groups below are considered only if places remain.
This is why MOE's balloting notes read, for example, “Balloting will be conducted for Singapore Citizen children residing between 1km and 2km of the school.” It names the exact group the ballot decided. MOE: how balloting is conducted →
The 1km and 2km rules
Distance is measured in a straight line from the address on the registering parent's NRIC to the school. It matters only as a priority band when a phase is balloted — it is not a score, and it does not change the number of places a school has.
Highest distance priority within a citizenship group.
Considered after those within 1km are placed.
Considered after the closer bands are placed.
There is also a stay requirement in some cases: a child admitted on the basis of distance (for example, under the grassroots-leader route in Phase 2B, or by distance priority in Phase 2C) is expected to live at the registered address for at least 30 months from the start of the exercise. MOE's pages explain exactly when this applies.

The PR cap
In Phases 2C and 2C Supplementary, MOE caps the number of Permanent Resident children each school can admit, so that a certain share of places stays with Singapore Citizen children. Where this cap is reached, a ballot may be conducted among PR applicants for the remaining PR places. It affects only PR children; Singapore Citizen children are placed ahead of PRs regardless.
How it is drawn
Within the one group being balloted, every child has the same chance. MOE runs the ballot by computer, and the order in which families registered during the phase makes no difference — registering at 9am on the first morning gives no advantage over registering later in the window. There is nothing to prepare for and nothing that improves a child's odds inside the balloted group.
Because the outcome is chance within a group, a school that held a ballot last year is simply one where, in that phase, more families applied than there were places. It is not a measure of quality. That is also why past figures are history, not a prediction: the same school may ballot in one year and not the next.
If it doesn't go your way
An unsuccessful ballot is not a failure, and it is not the end of the road. A place is assured — here is the path from here.
A calm, practical step for the next phase is to look at which nearby schools had more vacancies than applicants last year — MOE suggests exactly this. Our lookup tool shows each school's past figures, and MOE's live vacancies page shows where places remain right now.
It means that in a particular phase, one priority group had more applicants than the places left for it, so MOE drew a computerised ballot to decide who was admitted. A school that balloted is fuller, not better — it says nothing about the child or the quality of the school.
Within the group being balloted, every child has the same chance and nothing changes it — not the time you registered, and nothing about the child. The one thing MOE itself suggests is to consider schools that had more vacancies than applicants, which are less likely to need a ballot at all.
No. Registration is not first-come, first-served. As long as you register any time within the phase's dates, the time of registration makes no difference to the outcome or to a ballot.
You register in the next phase your child is eligible for, and Phase 2C Supplementary is available for children not yet placed. A child still unplaced after that is posted by MOE to a school with a vacancy. Every eligible child is assured a place. See the section above.
Singapore Citizen children are admitted ahead of Permanent Resident children in the same phase. In Phases 2C and 2C Supplementary there is also a cap on how many PR children each school admits. Within a citizenship group, priority then follows home-to-school distance.
