P1 Registration: Phases, the 1km Rule and What Actually Decides a Place
Every phase and who qualifies, how the distance bands set priority, the address rule that binds you for 30 months, and the point at which a ballot decides it instead of you.
The whole thing in one minute
Primary 1 registration runs in phases. You register in the earliest phase your child qualifies for, and most children are placed before the open phase is reached. If a phase draws more applicants than the school has places left, two things decide the outcome, in this order: citizenship, then how far you live from the school. If that still leaves a tie, MOE ballots.
Distance is the only one of those you can buy. That is why the 1km band moves property prices, and why it is worth understanding precisely what it does and does not do.
The short version: being inside 1km improves your position in a queue. It does not reserve a seat. At the most heavily subscribed schools, the citizen-within-1km band is itself over-subscribed, and a ballot decides it.
The phases
Which phase your child belongs in
Phases 1 through 2C Supplementary are for Singapore citizens and permanent residents. International students register separately, in Phase 3, after citizens and PRs have been placed.

| Phase | Who it is for |
|---|---|
| Phase 1 | A sibling is currently studying in the school. |
| Phase 2A | A parent or sibling is a former student of the school, including through membership of its alumni association; or a parent is a staff member; or the child is from the MOE Kindergarten located within that school. |
| Phase 2B | A parent has volunteered at the school, joining no later than 1 July of the year before registration and completing at least 40 hours of service by 30 June of the registration year; or a parent is endorsed by a church or clan directly connected with the school; or a parent is endorsed as an active community leader. |
| Phase 2C | Any child not yet registered in a primary school. This is the open phase, and the one most families use. |
| Phase 2C Supplementary | Children still without a place after Phase 2C, registering at schools with vacancies remaining. |
| Phase 3 | International students, through a separate two-step process before the phase opens. |
Swipe the table sideways if it is cut off.
Two of those deserve a flag. Phase 2A through the alumni route is the reason people join an old school's alumni association years early. And Phase 2B volunteering is a two-year commitment, not a sprint: joining by 1 July of the year before registration means starting roughly two years before your child sits in a P1 classroom. Neither can be arranged late.
MOE publishes an eligibility checker that tells you which phases apply to your child. Use it rather than a guide — including this one. MOE: phases and key dates
When a phase is over-subscribed
The order that actually decides it
A ballot can happen in any phase from 2A through 2C Supplementary. Before any ballot, MOE works down a fixed order of priority:
- Singapore citizens living within 1km of the school
- Singapore citizens living between 1km and 2km
- Singapore citizens living beyond 2km
- Permanent residents within 1km, then 1–2km, then beyond 2km
Every citizen is considered ahead of every PR, whatever the distance. Within each of those six groups, if applicants exceed the places left, MOE runs a computerised ballot conducted centrally, and everyone in that group has an equal chance.
Two reserved pools sit underneath all of this, so that a school cannot be filled entirely by siblings and alumni before the open phase begins. This is one of the things MOE changed on 10 September 2026.
- 2026 exercise (children entering P1 in 2027): 20 places reserved for Phase 2B and 40 for Phase 2C — 60 in total.
- 2027 exercise onward (children entering P1 from 2028): Phase 2B stays at 20, and Phase 2C rises to 60 — 80 in total. Schools with fewer than 180 P1 places keep 40 reserved for Phase 2C. The extra places come out of the earlier phases.
What this means in practice. Moving from the 1–2km band into the 1km band moves you up one rung of a six-rung ladder. At a school where the citizen-within-1km group already exceeds the remaining places, that rung still ends in a ballot. At a quieter school, it can be decisive. The difference between those two cases is worth knowing before you commit to a purchase, not after.
New from the 2027 exercise
The two-track Phase 2C, at 12 schools
Announced by MOE on 10 September 2026 and starting with the 2027 Registration Exercise (children entering Primary 1 in January 2028). At twelve named schools, Phase 2C stops using the six-rung ladder above and works like this instead:
- The school’s Phase 2C places are split equally into two tracks — one for applicants living within 2km, one for applicants living beyond 2km. At a school with 60 reserved places that is 30 and 30.
- There is no home-school distance priority inside a track. A family 400m away and a family 1.9km away have exactly the same chance.
- If Singapore citizen applicants in a track exceed its places, MOE ballots within that track.
- If a track does not fill, its remaining places go to Singapore citizen applicants in the other track.
- Citizens are still placed ahead of permanent residents in both tracks, and families eligible for Phases 1, 2A and 2B are still placed before Phase 2C begins.
MOE selected these twelve because public housing accounts for less than 40% of dwelling units within 2km of the school. It says it will review the list periodically as housing profiles change, but does not expect frequent changes.
| Area | Schools |
|---|---|
| Bukit Timah, Newton, Dunearn | Anglo-Chinese School (Junior) · Anglo-Chinese School (Primary) · Methodist Girls’ School (Primary) · Nanyang Primary School · Pei Hwa Presbyterian Primary School · Raffles Girls’ Primary School · Singapore Chinese Girls’ Primary School |
| Katong, Marine Parade | CHIJ (Katong) Primary · Ngee Ann Primary School · Tanjong Katong Primary School · Tao Nan School |
| City fringe | St. Margaret’s School (Primary) |

What this means if you are buying. At these twelve schools the graded advantage of a sub-1km address is gone in Phase 2C — but the 2km line still decides which track you are in, so proximity has become a cliff rather than a slope. Everywhere else in Singapore, the 1km band works exactly as it always did. I have written the property side of this up separately in what the P1 changes mean for buyers.
Distance
How the 1km band is determined
MOE assigns each address a home-school distance category — within 1km, between 1km and 2km, or beyond 2km — based on the address you register with. That category, not a raw number of metres, is what the priority order above uses.
MOE does not publish the geometry it uses, and it is worth being careful here, because a lot of what circulates online is guesswork. What MOE does say is that you should check your address's category for a given school using SLA's OneMap School Query service, in the year of your child's registration. That is the only figure that counts.
If you are close to the line, verify it before you commit. Any tool, mine included, is an estimate. A property that computes at 980m on a map is not a property MOE has confirmed at under 1km. Check the exact unit address on OneMap School Query, and treat anything within about 50m of the boundary as unresolved until you have.
To see which private projects sit inside a given school's band as a starting point, the 1km Primary School Check maps every condo, apartment and EC around all 179 primary schools with their actual transacted prices. Use it to build a shortlist; use OneMap to confirm the one you choose.
The address rule
Thirty months, and MOE means it
The address used for registration must be the parents' official residential address as it appears on their NRIC. If your child gains priority through the distance category, you are required to remain at that address for 30 months.
MOE is unusually direct about enforcement. It states that it takes a serious view of parents using an address solely to secure a place, that it will transfer a child out where it establishes an intention to abuse the system, and that giving false information is an offence which can be referred to the police. Parents who cannot show that what they declared was true and accurate are exposed to the same outcome.
So the honest way to read a purchase near a school is as a 30-month commitment to living there, not a registration tactic. If the plan involves moving out once the place is secured, it is not a plan.
If you are a PR
The cap in the open phases
A small number of schools carry a cap on permanent resident intake, set at roughly 25% to 30% of the school's planned P1 intake. It applies in Phases 2C and 2C Supplementary only, and MOE reviews and publishes the list of affected schools before each exercise. For the 2026 exercise those schools were Bukit Timah Primary, Cantonment Primary and Opera Estate Primary.
The cap does not change the priority citizens already hold over PRs in every phase. It limits how many PR children a specific school can take in the open phases, nothing more.
Timing
The 2026 exercise, and what comes next
The 2026 Primary One Registration Exercise ran from 30 June 2026 to 30 October 2026, for children born between 2 January 2020 and 1 January 2021 inclusive, entering Primary 1 in January 2027. Phase 3 applicants submitted an indication of interest in May 2026, ahead of the main window.
Individual phase dates shift each year and MOE publishes them per exercise, so this guide does not reproduce them — check the official page for the dates that apply to you.
Update, 11 September 2026: the review has concluded. On 10 September 2026 MOE announced two changes, both starting with the 2027 exercise — children entering Primary 1 in January 2028. Reserved Phase 2C places rise from 40 to 60 at most schools, and 12 named schools move to a two-track Phase 2C in which home-school distance no longer orders the queue. The 2026 exercise was not affected.
I have folded both changes into this guide. For the full breakdown, the list of 12 schools and what it does to the case for buying near a school, read my write-up of the changes.
The property decision
What a 1km address is actually worth
Families ask me to price this all the time, so here is the honest framing.
You are buying one rung on a six-rung ladder, for a minimum of 30 months, at a school whose ballot odds you cannot know in advance. At a school where the citizen-within-1km band clears comfortably, that rung is close to decisive and the premium can be rational. At a school where that band is itself balloted every year, you have paid a large premium for a better lottery ticket — still better odds, but a lottery.
Two things follow. First, the question worth answering is not “is this condo within 1km” but “how crowded is the 1km citizen band at this particular school”. Second, renting inside the band for 30 months is a legitimate and much cheaper way to hold the same position, and I say so to clients even though it earns me nothing.
If you do buy, buy something you would be content to own on its own merits, because the school reason expires after six years and the property does not.
Questions I get asked
P1 registration, answered
MOE announced two changes on 10 September 2026, both starting with the 2027 exercise for children entering Primary 1 in January 2028. Reserved Phase 2C places rise from 40 to 60 at most schools — schools with fewer than 180 P1 places keep 40, and Phase 2B stays at 20. And 12 named schools move to a two-track Phase 2C, splitting places equally between families within 2km and families beyond 2km, with no home-school distance priority inside either track. Full breakdown here.
Anglo-Chinese School (Junior), Anglo-Chinese School (Primary), CHIJ (Katong) Primary, Methodist Girls’ School (Primary), Nanyang Primary School, Ngee Ann Primary School, Pei Hwa Presbyterian Primary School, Raffles Girls’ Primary School, Singapore Chinese Girls’ Primary School, St. Margaret’s School (Primary), Tanjong Katong Primary School and Tao Nan School. MOE chose them because public housing is under 40% of dwelling units within 2km, and says it will review the list periodically.
No. Distance sets your position in the queue, it does not reserve a seat. Within a phase, places go to Singapore citizens within 1km first, then citizens 1–2km, then citizens beyond 2km, then permanent residents in the same three bands. If more children apply in a band than there are places left, MOE ballots inside that band. At a heavily subscribed school, a citizen family 400m away can still lose a ballot.
Phase 1 if an older child is already in the school. Phase 2A if a parent or sibling is an alumnus (including through the alumni association), a parent is staff, or the child is from the MOE Kindergarten inside that school. Phase 2B for qualifying parent volunteers, endorsed church or clan members, and endorsed active community leaders. Phase 2C is the open phase for any child not yet placed. MOE's own eligibility checker on its phases page is the authority.
A parent must have joined the school as a volunteer no later than 1 July of the year before registration, and given at least 40 hours of service by 30 June of the registration year. That means the commitment starts roughly two years before your child enters P1 — it is not something you can arrange in the months before registration opens.
Thirty months, if the place was gained through the home-school distance category. The address must be the parents' official residential address as shown on their NRIC. MOE states plainly that it takes a serious view of addresses used solely to gain a place: it can transfer a child out, and giving false information is an offence that can be referred to the police.
For the distance rule, an address is an address — provided it is genuinely your registered residential address on your NRIC and you meet the 30-month commitment. Renting is a far cheaper way to test a catchment than buying, and I would rather a client rented for 30 months than overpaid several hundred thousand dollars for a ballot slip.
Yes, but only in Phases 2C and 2C Supplementary, and only at schools MOE names before each exercise. The cap sits at roughly 25% to 30% of the school's planned P1 intake. For the 2026 exercise the schools were Bukit Timah Primary, Cantonment Primary and Opera Estate Primary. The cap does not change the priority citizens already hold over PRs.
