PSLE cut-off point for St. Joseph's Institution
MOE publishes the PSLE score of the first and the last student posted into each school at each posting group. Below are St. Joseph's Institution's figures for the 2026 Secondary 1 intake — the 2025 PSLE cohort. The last student's score is what is usually meant by the school's cut-off point.
| Posting group | Non-affiliated | Affiliated |
|---|---|---|
| Integrated Programme | AL 4–7 | — |
| Posting Group 3 | AL 4–8 | AL 7–12 |
Cut-off points move by a few points from year to year, and not every student who met the cut-off was posted here — some are tie-broken out. Read these as a guide to where a school sits, not as a threshold to clear.

What this intake means for the Maths your child will sit
A posting group decides the level a student takes each subject at from Secondary 1, not only which class they are in — and under Full Subject-Based Banding a student who did well enough in a subject at PSLE can take that subject at a more demanding level than their posting group's default. So the score above is the start of the Mathematics your child sits at St. Joseph's Institution, not the whole of it.
- Secondary 1 (IB) Math syllabus
These students follow a school-based integrated Secondary 1–4 course leading to the IB Diploma in the pre-university years.
- Secondary 1 G3 Math syllabus
Posting Group 3 students take Mathematics at G3 by default — the fastest of the three, and the usual route into Additional Mathematics from Secondary 3.

School Overview
St. Joseph's Institution (SJI) is one of Singapore's oldest and most storied schools, founded in 1852 by the De La Salle Brothers — a Catholic teaching congregation that established it as the first Lasallian school in Asia. Today, SJI operates as an independent secondary school under the Ministry of Education's Independent School scheme, giving it greater flexibility in curriculum design and admissions.
The school is rooted in the Lasallian tradition, which places equal emphasis on academic rigour and the formation of character. Its mission to provide a rounded education — one that develops young men intellectually, morally, and socially — remains central to everything from classroom instruction to co-curricular programmes. SJI offers a national secondary pathway leading to the O-Level or Secondary Education Certificate (SEC), depending on the cohort, and an Integrated Programme leading to the IB Diploma at SJI in Years 5 and 6. SJI International is a separate school.
Located along Malcolm Road in the Novena area, the school serves Secondary 1 through 4, with students typically entering via the Direct School Admission (DSA) exercise or through posting based on PSLE results. SJI is a boys' school, and its strong network of Lasallian institutions in Singapore — which includes St. Patrick's School and De La Salle School — reflects a shared educational heritage spanning more than 170 years.
Academic Excellence
SJI offers a broad and balanced curriculum across the four years of secondary education, covering humanities, sciences, mathematics, and the arts. As an independent school, it has the latitude to supplement the national syllabus with enrichment programmes and specialised learning tracks that respond to students' strengths and interests.
The school's Applied Learning Programme (ALP) centres on design thinking and innovation, encouraging students to approach complex, real-world challenges using structured problem-solving methods. This complements strong offerings in Mathematics and the Sciences, where students regularly participate in national and international competitions — including the Singapore Mathematical Olympiad and various inter-school science challenges.
SJI also places significant weight on bilingual education and the humanities. Students are expected to engage seriously with literature, history, and the social sciences, not merely as exam preparation but as disciplines that sharpen reasoning and ethical thinking. This broad intellectual formation has contributed to a graduate profile that is valued by junior colleges and universities alike.
For families whose sons need additional support in Mathematics — particularly those preparing for the O-Level examinations — DeepThink offers structured small-group classes aligned to the MOE secondary Mathematics syllabus, and tutors are familiar with the pace and expectations of independent schools like SJI.
Facilities and Extracurricular Activities
SJI's campus has been developed over many decades and includes well-equipped science laboratories, a performing arts centre, sports halls, and dedicated spaces for CCAs ranging from robotics to visual arts. The school's facilities reflect its status as an independent institution with the resources to invest in purposeful learning environments.
The Co-Curricular Activity (CCA) programme at SJI is extensive. Uniformed groups include the Boys' Brigade and the National Police Cadet Corps. Sports CCAs cover Basketball, Football, Swimming, Tennis, Badminton, and Track and Field, among others. The Performing Arts scene is active, with options in Choir, Drama, Chinese Orchestra, and various instrumental ensembles. Clubs and societies span interests from Astronomy and Robotics to Debate and Community Service.
SJI's Learning for Life Programme (LLP) focuses on leadership and values formation through structured service-learning experiences. Students are encouraged to take on responsibilities within their communities — whether through school-level initiatives or external partnerships — as part of the school's long-standing commitment to producing graduates who contribute meaningfully beyond their own advancement.
The school's alumni network is broad and spans fields including law, medicine, business, engineering, and public service. Notable former students include several prominent figures in Singapore's political and civic life, reflecting the school's long history of educating the country's leaders.
Parents looking to complement SJI's in-school Mathematics programme will find that DeepThink's IB-aware and O-Level-aligned tutoring can provide targeted support, particularly for students navigating the more demanding tracks within the school's curriculum.

Frequently asked questions
Clear answers for parents
Which Math class suits a St. Joseph's Institution student?
The relevant pathways are G3 national Mathematics; IP → IB Diploma. We use the student's current Mathematics course, year and schoolwork to choose a class. The national and integrated pathways have different assessments, so the school name alone does not determine the class.
Does the posting group determine my child's Mathematics class?
It indicates the usual starting subject level, but Full Subject-Based Banding allows students to take subjects at different levels. Tell us the Mathematics level shown on your child's timetable or assessments so lessons match what they actually study.
How does DeepThink support St. Joseph's Institution's IP Mathematics?
IP schools set their own topic sequences and internal assessments. We use the student's school materials to reinforce concepts, practise unfamiliar problems and prepare for current assessments. St. Joseph's Institution's IP pathway leads to the IB Diploma.
Are secondary IB-pathway lessons the same as IB Diploma lessons?
The secondary years build towards the Diploma. Schools may use their own pre-IB course, MYP or IGCSE, with different topic sequences and assessments. These secondary course links cover the years before the Diploma; share the actual school course and year so we can confirm the right fit.
When should a secondary student start tuition?
Start when schoolwork reveals gaps in understanding or confidence. Earlier support can strengthen algebra and problem-solving foundations; students joining later can focus on their current topics and assessments.
What makes DeepThink different for St. Joseph's Institution students?
Small classes, teaching matched to the student's actual Mathematics course, and practice that develops clear working as well as correct answers. Parents are kept informed about progress and areas needing more practice.
How many students are in each class?
Four, at most. Students are grouped by learning pace, not just by year level, so each lesson moves at the speed of the students actually in it. When no session matches a child’s pace, we open a new one. In a class that size, every child answers questions, gets their working checked, and gets help the moment they need it.
Does DeepThink have a class for SJI's IB curriculum?
Yes. We support the secondary years of SJI’s IP pathway leading to the IB Diploma. Students on SJI’s national pathway receive support for their G3 Mathematics and Additional Mathematics courses instead.
Can families start with a trial class first?
Yes. A trial class helps you see whether our teaching pace and approach suit your child’s learning needs. Trials in existing classes are free. A dedicated trial session at a different timeslot is offered at a subsidised rate of $30. We’ll help you explore the available options.
