What Triggers a Ballot?
A ballot occurs when the number of eligible applicants in a registration phase exceeds the number of remaining vacancies at a school. MOE then conducts a computerised random ballot among all eligible applicants in that phase. Every eligible child has an equal probability of being selected — there is no advantage to applying earlier within the phase window.
Reading the Balloting Data
SGSchool displays historical P1 registration data for each school, including the number of applicants and places taken in each phase. This data helps you answer three key questions:
- Which phase does balloting typically start? If a school ballots in Phase 2B, Phase 2C will have very few (or zero) vacancies. You need an earlier-phase advantage to have a realistic chance.
- How competitive is Phase 2C? Compare the number of applicants to the vacancies available. A school with 200 Phase 2C applicants for 10 spots has a 5% success rate — very tough odds.
- Has the school's demand changed over time? Some schools have grown more competitive due to new transport links or increasing reputation. Check multi-year trends where available.
Distance Priority Within a Phase
Within any phase that goes to ballot, MOE first allocates places to Singapore Citizens over PRs. Among citizens, distance from home to school is the tiebreaker, in three bands:
- Within 1 km
- Between 1 km and 2 km
- Beyond 2 km
If the number of applicants within a distance band still exceeds vacancies, a ballot is held within that band. Living within 1 km gives you the best odds, but it does not guarantee a place at very popular schools.
Strategies Based on Balloting History
Phase 1 and 2A Schools
If your family has sibling ties or alumni connections to a school, your child will register in Phase 1 or Phase 2A. These phases rarely ballot, so your chances are high — but do confirm by checking the school's historical data.
Phase 2B Volunteer Strategy
Volunteering 40 hours at a school allows you to register in Phase 2B, which typically has more vacancies than Phase 2C. If your target school frequently oversubscribes in Phase 2C, volunteering in Phase 2B is a meaningful advantage. Start early — volunteer rosters fill up quickly at popular schools.
Phase 2C: Choose Strategically
If you're entering via Phase 2C, prioritise schools where historical data shows reasonable Phase 2C vacancies and a success rate above 50%. Targeting an oversubscribed school in Phase 2C with 3% success odds is risky unless you have a strong distance advantage (within 1 km).
What Happens If You Don't Get a Place?
Children who do not secure a place in any phase will be allocated to a school by MOE, typically one near your registered address with available vacancies. While parents do not get to choose the allocated school, MOE ensures every child has a school place.
Conclusion
Balloting data is your best tool for making a realistic school choice. Use SGSchool to explore each school's historical registration statistics, identify which phases are competitive, and build a shortlist that balances your aspirations with your practical advantages.
