P1 Registration in Singapore: Phases, Balloting and How the Odds Really Work

Primary 1 registration places every child in a national school through a fixed sequence of phases, and your child's phase is decided by facts you mostly cannot change: siblings, alumni ties, volunteering, and home distance. Understanding which phase you register in, and what the balloting odds look like inside it, matters far more than any last-minute manoeuvre. Every year I walk tuition families through this exercise, and the parents who plan around their phase, rather than against it, are consistently the calmest in July.

Here is how the exercise works, phase by phase, and how to think about your real chances.

The registration sequence at a glance

Registration for entry to Primary 1 runs in one national exercise the year before your child starts school. Children born between 2 January 2020 and 1 January 2021 register in the 2026 exercise for January 2027 entry. The phases always run in the same order, and each phase only opens after the one before it closes:

The official phase criteria are set out on MOE's P1 registration page, which is the source to check before you rely on any summary, including this one.

This year's dates

For the 2026 exercise (2027 intake): Phase 1 ran 30 June to 2 July, Phase 2A on 9 and 10 July, Phase 2B on 20 and 21 July, and Phase 2C from 28 to 30 July. Phase 2C Supplementary runs 17 to 18 August. Results for each phase are released within about a week of that phase closing. If you are reading this between phases, the number that matters is the vacancy count each school publishes before the next phase opens.

How balloting actually works

A phase only ballots when a school has more applicants than places in that phase. When it does, priority runs by citizenship first, Singapore Citizens ahead of Permanent Residents, and then by home-school distance in three bands: within 1 km, between 1 and 2 km, and beyond 2 km.

The practical consequence: a Singapore Citizen child living within 1 km of a school is in the strongest position its phase allows, and a child beyond 2 km in a popular school's Phase 2C is in the weakest. Balloting is a lottery only within a band, everything before that is deterministic.

The 1 km question, honestly

Some families move house for the 1 km band, and the address rules are strict: you must be living at the address, and if you use an address to secure a place, MOE requires the family to reside there for at least 30 months from the start of the registration exercise. Moving purely on paper is both against the rules and regularly checked.

My honest advice after years of watching this play out: the school your child can walk to, sleep well for, and attend without an hour of daily transport is usually worth more than a famous name two towns away. Primary school outcomes track the child's daily energy far more than the school's brand.

If you reach 2C Supplementary

Not getting a place in 2C feels alarming and is almost always fine. In 2C Supplementary, MOE places every remaining child, and you can list schools that still have vacancies. The strong play is to shortlist by travel time and vacancy count rather than reputation, and to remember that every national primary school teaches the identical MOE syllabus with the same PSLE at the end of it.

Choosing between two reachable schools

When two schools are genuinely within reach, compare the things that touch your child daily: the travel route at 6.45 am, not on a quiet Sunday; whether the CCAs your child might love exist there; and the school's after-care arrangements if both parents work. Cut-off prestige is the least useful tie-breaker at this age, every national primary school runs the same syllabus toward the same PSLE, and the daily-life factors compound for six years.

What actually prepares your child

None of the phases test the child, P1 has no entrance exam, and MOE removed all weighted assessments for P1 back in 2019. What helps in the first term is much simpler: counting small sets confidently, recognising numbers to 10, holding a pencil comfortably, and being read to daily. If you want a concrete picture of what P1 Mathematics covers, our free P1 Maths course on Infinity walks the whole syllabus one chapter at a time, and our Primary Maths tuition picks up from there if your child wants a head start.

Common questions

When is P1 registration for the 2027 intake?
The 2026 exercise opened on 30 June 2026 and runs through the phases to 2C Supplementary on 17 and 18 August 2026, for children starting Primary 1 in January 2027.

Does every school ballot in Phase 2C?
No. Balloting happens only when applicants outnumber places in a phase. Schools publish vacancies before each phase, so you can see the pressure before you commit.

Is a child within 1 km guaranteed a place?
No, but a Singapore Citizen within 1 km is in the highest-priority group of the phase. If that group alone oversubscribes the phase, it ballots within the group.

What happens if my child has no place after Phase 2C?
The 2C Supplementary phase places every remaining child in a school with vacancies. No child is left without a school.

Do private or international schools follow this system?
No. This exercise covers MOE national primary schools only.
