Maris Stella Primary 2027 is going co-ed, moving to Mattar Road, and adding 60 new P1 places. Here’s the complete guide for Bidadari parents on registration rules, session times, and what it means for District 13 property.
When my neighbours started asking me about Maris Stella Primary 2027 — and they all seemed to be asking at once — I realised most of the information circulating was half-wrong. Parent WhatsApp groups were mixing up the temporary address with the registration address. Some thought the co-ed change meant the school was losing its SAP status. Others hadn’t even heard about the rebuild.
So this post is what I’d want someone to hand me: the facts, the implications, and the things that actually matter for your decision. I track school zone boundaries as part of my work in this area — and I’ve gone through the official MOE documents and the school’s own Key Information page so you don’t have to.
Maris Stella Primary 2027 marks one of the most significant transitions in its nearly 70-year history. Three things are happening at once: a full campus rebuild, a move to a temporary holding site, and the opening of its doors to girls for the first time. If your child is targeting P1 in 2027, 2028, or 2029 — this affects you directly.
Maris Stella Primary 2027: The Quick Version for Time-Poor Parents
Your 5-Point Action Checklist
Even though the school moves to 2 Mattar Road from Jan 2027, MOE calculates your Home-School Distance using 25 Mount Vernon Road. Locked in for the entire rebuilding period. Note: the School Land Boundary may shift slightly during construction, so re-verify on OneMap each year.
The school officially confirmed an increase of 2 classes (60 students) from 2027. No gender quota — open balloting for both boys and girls.
Pioneer co-ed intake. If you have a daughter, a historically closed SAP school door is now open. Same registration process as always — no quota for either gender.
MSHS (Primary) officially confirmed they do not have a Parent Volunteer programme for P1 registration priority. Save the energy for other schools if PV priority is part of your strategy.
The School Land Boundary may be updated during construction. Don’t rely on last year’s check. OneMap is updated by June each year ahead of the registration exercise.
By the Numbers
A Bit of History — Because Context Actually Matters
To understand why Maris Stella Primary 2027 is such a big deal, a bit of history helps. Maris Stella wasn’t born with a fancy campus. Founded in 1957 by the Marist Brothers — a Catholic teaching order inspired by Saint Marcellin Champagnat — the school spent its early years borrowing classrooms wherever space allowed. It wasn’t until 1966 that the school put down permanent roots at Mount Vernon Road.
That heritage is being respected in the rebuild. The iconic blue-and-white gate at Mount Vernon has been gazetted as a heritage item. When the new campus opens — tentatively in 2030 — that gate comes back up. A symbol of the school, re-erected in front of a brand new building.
For nearly seven decades, it was an all-boys Catholic SAP school. The decision to go co-ed at the primary level wasn’t taken lightly — it required formal sign-off from both MSHS Ltd’s Board of Directors and the Marist Brothers Provincial Council. The secondary section remains all-boys for now, and the school has confirmed there are currently no plans to change that.
Maris Stella Primary 2027: The Full Timeline
| Year | Where | What’s different | Status |
|---|---|---|---|
| 2026 | 25 Mount Vernon Rd | Final all-boys intake, original campus | Last Traditional Year |
| 2027–2029 | 2 Mattar Road (former MacPherson Primary) | Co-ed, +60 P1 places, partial single-session, student care available | Holding Site |
| 2030 onwards | 25 Mount Vernon Rd (rebuilt) | Co-ed, full single-session, brand new facilities | New Era |
In 2027, only P1 classes will be co-educational. P2 to P6 remain all-boys as those cohorts complete their primary journey. This also means you cannot transfer an older daughter into the school just because your younger daughter secures a P1 spot. Siblings born in 2021 or later will be able to join the co-ed intake in future years.
Maris Stella Primary 2027 School Hours: The Exact Times
Straight from the school’s official FAQ — not community speculation.
The school will provide full-day student care (7.00am – 7.00pm) for all primary Marists at the holding site. School bus services will also operate to and from Mattar Road for both sessions. These were the two biggest practical concerns — both addressed.
The MOE Rules: What Stays, What Changes
Check the MOE P1 Registration page for the official details. Here’s the plain-English version.
Distance calculation — address is Mount Vernon, but re-check yearly
Your HSD priority is based on your distance from 25 Mount Vernon Road — not Mattar Road. However, the School Land Boundary may change slightly during construction. MOE updates OneMap by June each year. Always re-verify your distance for the year you’re actually registering.
Caregiver addresses — this trips people up every year
Using a grandparent’s or caregiver’s address automatically places you in the 1km–2km band — regardless of how close they actually live to the school. Your own residential address is the only way to secure 1km priority. This is a fixed MOE rule.
The 30-month rule — if you’re planning a move, read this
Secure a P1 place using distance priority and you must stay at that address for at least 30 months from registration. If you’re planning to move in the next two to three years, time it around this window. The rule has teeth.
Maris Stella Primary 2027: Is the Holding Site Actually Worse?
This is the anxiety I hear most. Parents picture a temporary site as a downgrade — portable classrooms, crowded corridors, no field. The reality is different.
According to the school, the Mattar Road holding site has facilities the heritage Mount Vernon campus doesn’t: a proper school field, an indoor sports hall, sheltered courts, an auditorium, and classrooms that are 30% bigger. The school is currently renovating the site — new paint, returfed field, replaced floor tiles on the parade square.
It’s not a consolation prize. For the three years your child is there, it may actually be the better physical environment.
80% of MSHS Primary’s teaching staff are female. Over 70% have previously taught in co-educational schools. The school isn’t figuring this out on the fly — the infrastructure is already there. New girl’s uniform (white top, blue skorts) will be available for purchase at the end of 2026.
What This Means for Property in the Area
I track school zones as part of my work — here’s the honest read. More context on how I look at District 13 here.
MOE anchoring the registration address at Mount Vernon — not Mattar Road — is a value-lock for homeowners in Bidadari, Potong Pasir, and the surrounding streets. The educational premium on properties within the 1km circle stays intact throughout the construction period.
For buyers: the question isn’t “is the school nearby” — it’s “am I within 1km of 25 Mount Vernon Road.” Those are not the same answer for every address in the area, and the difference is a phase change in balloting.
For sellers: the co-ed transition expands your buyer pool. Families with daughters previously had no reason to factor Maris Stella into their school-proximity decisions. From 2027 onwards, they do. That’s a structural change in demand, not a one-off blip.
If your child is in the pioneer P1 batch of 2027, the risk/reward stacks up well. Three years at a holding site that’s genuinely well-equipped. In return: 60 extra places improving your Phase 2C odds, pioneer-year status in a historic transition, and a brand-new campus by the time your child hits P4. Not a bad trade at all.
Maris Stella Primary 2027: FAQ
Primary section only, and progressively — P1 goes co-ed in 2027, subsequent levels follow year by year as new cohorts come in. The Secondary section remains all-boys. The school has confirmed there are currently no plans to change this.
No. Transfers aren’t permitted under this transition model. Only siblings born in 2021 or later will be able to join the co-ed intake in future years through normal P1 registration.
No. It remains a Special Assistance Plan (SAP) school with its bilingual programme fully intact. The rebuild is MOE investing in the school’s long-term future — that’s not a demotion signal.
No. MSHS (Primary) officially confirmed they do not run a Parent Volunteer programme for P1 registration purposes. Don’t factor this into your strategy.
Both confirmed. School bus services will run to and from the holding site for both sessions. Full-day student care (7am–7pm) is available for all primary students. These aren’t pending decisions — they’re committed.
Current intake is approximately 270. From 2027, the school adds 2 classes — 60 more students — bringing the total to around 330. No gender quota: same open registration process for both boys and girls.
The school’s own official page says “tentatively in 2030.” Earlier MOE announcements mentioned 2029 as a possibility. Plan for 2030, treat anything earlier as a bonus.
You can, but MOE automatically places caregiver addresses in the 1–2km band regardless of actual proximity. Your own registered residential address is the only route to 1km priority.
