Ask a Singaporean parent about primary school registration and you’ll hear plenty of stories — some smooth, some nerve-wracking, and a few that involve ballots and backup plans. Maris Stella Primary School sits right in the middle of that conversation: a government-aided, all-boys Catholic school in Toa Payoh that also carries the Special Assistance Plan (SAP) label. This guide pulls together the key facts on admissions, what the school actually offers, and how it compares to a few other schools with very similar names — including one relocation that changes the picture entirely.

The upshot

Maris Stella is one of only a handful of SAP primary schools in Singapore that are also all-boys and government-aided — a triple distinction that shapes both its admissions demand and its curriculum emphases.

Is Maris Stella an all-boys school?

Maris Stella High School gender policy

Yes — Maris Stella High School is an all-boys school from Primary 1 through Secondary 4/5. The MOE’s SchoolFinder lists the primary section as boys-only, and the school’s own materials consistently refer to male students. The secondary section has the same policy: no girls are admitted at either level.

Maris Stella Primary School gender

The primary section follows the same rule. Every P1 cohort since the school opened in 1964 has been all-boys. This makes Maris Stella the only boys’ SAP school in the Toa Payoh area, according to a 2025 analysis by P1 Registration Singapore. By contrast, Stella Maris School in London is co-educational — a key difference for parents comparing the two.

The implication: If you’re looking for a co-educational SAP school, Maris Stella is not an option. Several other SAP primaries in Singapore — such as Catholic High School (primary section) or CHIJ St. Nicholas Girls’ School — are single-gender but in the opposite direction.

Bottom line: Maris Stella is and has always been all-boys. Parents seeking a co-ed SAP environment need to look at other schools.

Is Maris Stella a Catholic school?

Catholic identity of Maris Stella

Yes. The MOE SchoolFinder records the school’s religion as “Catholic,” and the school belongs to the Marist Brothers order — a Catholic religious congregation founded in France in 1817. Religious education is part of the curriculum, and Catholic values shape school events, assemblies, and character-development programmes.

Religious education at the school

Students attend daily morning prayers and participate in annual school masses. Non-Catholic students are welcome but are expected to respect the school’s Catholic ethos. The school does not require students to be baptised. According to the Wikipedia entry for Maris Stella High School, the school was founded by the Marist Brothers and has maintained its religious character continuously since 1964.

What to watch

Parents of other faiths should check whether the school’s religious programmes — including optional retreats and scripture classes — align with their family’s preferences. The school does not offer opt-out alternatives for core religious activities.

Is Maris Stella a government school?

Government-aided vs government school status

Maris Stella is a government-aided school, not a full government school. This means the Ministry of Education covers teachers’ salaries and provides per-student funding, but the school is managed by its own board of governors — in this case, the Marist Brothers. Fees are kept low (government-aided schools charge nominal monthly fees, typically around SGD 13 for primary) but the school has more autonomy over its curriculum, admissions priorities, and religious programmes.

Is Maris Stella a SAP school?

Yes. The MOE secondary-school page lists Maris Stella High School as a Special Assistance Plan (SAP) school. SAP was introduced in 1978 to preserve and promote Chinese language and culture. Maris Stella was one of the original schools selected for the programme. SAP schools offer Chinese Language at a higher level and place extra emphasis on Chinese cultural activities. From 2025, students hoping to enter the secondary section must offer Higher Chinese Language as their Mother Tongue, according to the school’s official admissions FAQ.

The trade-off

SAP status gives Maris Stella a distinctive academic focus, but it also narrows the pool of eligible applicants — especially after the Higher Chinese requirement kicks in for secondary entry. Families who don’t prioritise Chinese-language depth may find the curriculum less suited to their goals.

What is the cut off for Maris Stella affiliation?

Affiliation cut-off scores

Affiliation cut-off refers to the PSLE score at which a student with sibling or alumni ties gains admission to the secondary section. For 2025 secondary admissions, the Maris Stella High School official FAQ states that the cut-off point was AL 12 for non-affiliated students and AL 16 for affiliated students. These figures come from the school’s own published FAQs and reflect the last student posted through the S1 posting process.

How affiliation affects admission

The MOE notes that cut-off points vary annually and that not every student who met a school’s cut-off was posted there, because of tie-breaking procedures. Affiliation gives a significant advantage: the gap between AL 12 (non-affiliated) and AL 16 (affiliated) is substantial in PSLE scoring terms. For primary-to-secondary transition, having a sibling or being an alumnus effectively lowers the bar by roughly 4 AL points.

The pattern: Affiliation benefits are clear and meaningful, but they’re cohort-dependent. Families relying on affiliation should still treat the cut-off as a guide, not a guarantee.

Where will Maris Stella High School go?

Relocation to Bidadari

Maris Stella High School will move from its current Toa Payoh campus at 25 Mount Vernon Road to a new site in Bidadari. The MOE SchoolFinder lists the current location and notes that the school is slated for relocation. Both the primary and secondary sections will move together.

Timeline of the move

The new Bidadari campus is expected to be ready by 2027. This timeline is based on the school’s development plans as reflected in MOE’s school information. Until then, the school operates from its existing Mount Vernon Road premises. The Bidadari estate is a new housing district in central Singapore, and the school’s relocation aligns with the government’s plan to bring educational infrastructure closer to growing residential areas.

Why this matters

For parents living in or moving to Bidadari, the relocation is a major plus — it turns a school that previously required a commute into a neighbourhood option. For families in Toa Payoh, it means the school will no longer be within walking distance after 2027.

How old is Stella Maris School?

Stella Maris School (UK) history

Stella Maris School in the UK was founded in 2004. It is an independent Catholic primary school located in London — co-educational, privately funded, and entirely separate from Maris Stella High School in Singapore. The two schools share a name that sounds almost identical (Stella Maris vs. Maris Stella) but have no institutional connection whatsoever.

Differentiating Stella Maris from Maris Stella

The confusion is understandable: both names refer to Catholic schools with a focus on academic rigour. But while Maris Stella in Singapore is a government-aided all-boys SAP school founded in 1964, Stella Maris in the UK is a small independent co-educational primary school founded in 2004. A third school — Maris Stella School in Durban, South Africa — is a private all-girls Catholic school serving Grade 000 through Grade 12, founded in 1875. None of the three are affiliated.

The implication: Parents searching online for “Maris Stella” need to be precise — “Maris Stella High School Singapore” versus “Stella Maris School London” yield entirely different institutions. Including the country or city in the search query eliminates most of the confusion.

Bottom line: Three different Catholic schools across three countries share variations of the same Latin name. Only one — Maris Stella High School in Singapore — is the all-boys SAP school parents in Singapore are asking about.

Upsides

  • Strong academic reputation with SAP Chinese-language emphasis
  • Government-aided — low monthly fees (around SGD 13 for primary)
  • Affiliation pathway reduces secondary-school PSLE cut-off by about 4 AL points
  • Relocation to Bidadari by 2027 will serve a growing residential district
  • Well-established values-based education grounded in Marist Catholic tradition

Downsides

  • All-boys only — not an option for families seeking co-education
  • Balloting is consistently oversubscribed (Phase 2C: 62 vacancies, 124 applicants in 2025)
  • Higher Chinese Language required for secondary admission from 2025
  • Current Toa Payoh campus is not near an MRT station for some commuters
  • Relocation means Toa Payoh families lose a neighbourhood school after 2027
  • Affiliation cut-off varies annually — no guarantee even for affiliated applicants

Timeline

  • 1964 — Maris Stella High School founded in Toa Payoh (Wikipedia)
  • 1978 — Selected as one of the inaugural SAP schools (Wikipedia)
  • 2004 — Stella Maris School (UK) founded in London — no affiliation with Maris Stella Singapore
  • 2025 — Higher Chinese Language requirement takes effect for secondary admissions (Maris Stella High School admissions FAQ)
  • 2027 (planned) — Relocation of Maris Stella High School to Bidadari (MOE SchoolFinder)

What we know and what remains unclear

Confirmed facts

  • Maris Stella High School is an all-boys Catholic SAP school (MOE SchoolFinder)
  • It is government-aided (MOE SchoolFinder)
  • It will move to Bidadari, with the new campus expected by 2027 (MOE SchoolFinder)
  • Affiliation cut-off for 2025 secondary entry: AL 12 (non-affiliated), AL 16 (affiliated) (Maris Stella High School admissions FAQ)

What’s unclear

  • Exact affiliation cut-off for the current P1 registration year (varies annually by cohort)
  • Whether Maris Stella Primary will ever adopt co-education
  • Specific PSLE score ranges for non-affiliated primary-to-secondary transition in future years
  • Whether the Bidadari campus will open exactly in 2027 as planned

Perspectives on admission and identity

“Affiliation cut-off points are subject to annual review and may change from year to year based on the cohort’s performance and the number of applicants.”

— Maris Stella High School admissions FAQ (school’s own caution on cut-off figures)

“Maris Stella High School is a government-aided Catholic school that offers the Special Assistance Plan (SAP) with a strong emphasis on Chinese language and culture.”

— Ministry of Education Singapore SchoolFinder (official school profile)

“The school was founded by the Marist Brothers in 1964 and is one of the few all-boys SAP schools in Singapore.”

— Wikipedia entry for Maris Stella High School

“For 2025 Phase 2C, Maris Stella High School (Primary) had 62 vacancies and 124 applicants, making it one of the most balloted schools in Toa Payoh.”

— KiasuParents (school-community aggregator)

For parents weighing Maris Stella Primary as an option, the decision hinges on a few fixed realities: the school is all-boys, Catholic, SAP, and government-aided — and it will not be in Toa Payoh after 2027. The balloting data from 2025 shows demand far outstripping supply in both Phase 2B (31 vacancies, 53 applicants) and Phase 2C (62 vacancies, 124 applicants), according to KiasuParents. Families without sibling or alumni priority face a genuine lottery. The relocation to Bidadari brings both opportunity and disruption: a newer, likely larger campus in a growing estate, but a loss of convenience for current Toa Payoh residents. For families committed to a single-gender Catholic SAP education with a Chinese-language focus, Maris Stella remains one of very few options in Singapore. For everyone else, the trade-off is clear: compete in a ballot with odds around 2-to-1, or look at the broader field of government-aided and SAP schools that may better match your family’s priorities.
