PSLE cut-off point for Commonwealth Secondary School
MOE publishes the PSLE score of the first and the last student posted into each school at each posting group. Below are Commonwealth Secondary School'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 | PSLE score range |
|---|---|
| Posting Group 3 | AL 8–13 |
| Posting Group 2 | AL 21–23 |
| Posting Group 1 | AL 25–28 |
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 Commonwealth Secondary School, not the whole of it.
- 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.
- Secondary 1 G2 Math syllabus
Posting Group 2 students take Mathematics at G2 by default, covering most of the G3 content at a steadier pace.
- Secondary 1 G1 Math syllabus
Posting Group 1 students take Mathematics at G1 by default, building the foundations in smaller steps.
- Secondary Math syllabus, all four years

School Overview
Commonwealth Secondary School traces its origins to 1964, when it was established as Tanglin Integrated Vocational Secondary School — one of Singapore's early institutions serving vocational education needs. The school was subsequently renamed Commonwealth Secondary School in 1999, and it gained autonomous status in 2000, granting it greater flexibility in programme design while remaining within the public education framework.
Today, Commonwealth Secondary is a government autonomous co-educational school offering secondary education from Secondary 1 through 4/5 on a single-session timetable. The school operates under the motto "Strive with Integrity, Excel with Pride" and is guided by its core values of Warmth, Enterprise, Attitude, Motivation, and Integrity. Its educational approach centres on developing caring communities of learners who think critically, show curiosity, and grow into confident leaders — with the belief that every student has distinct strengths worth cultivating.
Since 2008, Commonwealth Secondary has served as a Higher Chinese Centre, providing enriched bilingual learning opportunities. The school also offers distinctive programmes including a STEM elective, a Design elective, and the Language Elective Programme in Tamil, giving students access to specialised tracks that blend cultural and technical learning.
Admission Process
Entry to Commonwealth Secondary School at Secondary 1 takes place through two main pathways: the PSLE posting exercise and the Direct School Admission (DSA) scheme.
For PSLE-based admission, placement depends on Achievement Level (AL) scores. Based on the 2024 intake, the indicative AL score ranges for non-affiliated students were: Posting Group 3 at 8–12, Posting Group 2 at 21–23, and Posting Group 1 at 25–27. These figures reflect the scores of the last students offered places in that cycle and may shift from year to year. Commonwealth Secondary is not affiliated with any primary school, so there is no affiliation bonus during posting.
The DSA scheme allows students to apply for admission based on demonstrated ability in specific talent areas before PSLE results are released. DSA categories at Commonwealth Secondary have included Performing Arts (Band, Dance), Sports (Badminton, Basketball, Football, Netball), and Leadership and Community Service areas such as Robotics, Environmental Science, and Uniformed Groups. Applications are submitted through the MOE DSA portal, which typically opens around May each year for entry the following January.
All incoming Secondary 1 students are placed under Full Subject-Based Banding (SBB), which enables them to take individual subjects at different levels according to their strengths from the start of secondary school. Commonwealth Secondary follows the O-Level and N-Level pathway — it does not offer an Integrated Programme.
Curriculum and Academic Programme
Commonwealth Secondary follows the national curriculum framework and prepares students for the GCE O-Level and N-Level examinations. Core subjects include English Language, Mathematics (Elementary and Additional), Sciences (Biology, Chemistry, Physics), and Humanities (Geography, History, Social Studies). Under Full Subject-Based Banding, students may take subjects at more demanding levels based on their individual aptitude, allowing for a more tailored academic experience across the Express, Normal (Academic), and Normal (Technical) streams.
Beyond the standard curriculum, the school offers elective subjects and specialised tracks. These include Higher Chinese, Higher Malay, Higher Tamil, Computing, Literature, Art, Design and Technology, and Music. The STEM elective programme encourages students to engage with science and technology through project-based learning, while the Design elective develops creative problem-solving skills. The Language Elective Programme in Tamil provides an enriched pathway for students with strong Tamil language ability.
The school has achieved notable results in academic and creative competitions. In 2024, a Commonwealth Secondary team earned a Gold Award at the International Science Drama Short Film Competition held in Beijing. Students have also received Merit Awards in various national competitions, and several were recognised as Pinnacle Awardees for outstanding leadership in 2025. The school reports that over 90% of recent cohorts have qualified for post-secondary education pathways.
Families looking for additional support in Mathematics may wish to consider DeepThink, a math tuition centre that offers structured programmes aligned to the O-Level and N-Level syllabuses, which can complement the school's curriculum for students who benefit from extra practice and reinforcement.
Facilities and Co-Curricular Activities
Commonwealth Secondary School's campus features facilities designed to support both academic learning and hands-on exploration. The school has smart classrooms fitted with interactive technology, fully equipped science and computer laboratories, and a well-stocked library. Sports facilities include a synthetic turf field and multi-purpose courts. The campus also incorporates environmentally focused installations such as a wetland area and a food waste composting system, which serve as practical learning resources for sustainability education.
Co-Curricular Activities (CCAs) are a core part of the student experience and span four main categories:
Sports: Badminton, Basketball, Cross Country, Dragon Boat, Football, Netball
Performing Arts: Choir, Concert Band, Indian Dance, Modern Dance, Percussion Ensemble
Clubs and Societies: Broadcasting, Coding, Debate, English Drama, Environmental Science, Robotics, Tamil Language

CCA participation contributes to students' holistic development and can also strengthen DSA applications for those applying to junior colleges or other post-secondary institutions.
Student Life and School Culture
School life at Commonwealth Secondary is shaped by its emphasis on care, inclusivity, and character development. The school's core values — Warmth, Enterprise, Attitude, Motivation, and Integrity — are woven into daily routines, assemblies, and interactions between students and staff.
Pastoral care is a central feature of the school's approach. Form teachers work closely with their classes, and counselling services are available to support students' emotional and social well-being. The school runs programmes focused on resilience, empathy, and responsible decision-making as part of its broader character education efforts.
Education and Career Guidance (ECG) experiences help students understand their strengths and explore post-secondary options. Tools such as the DISC personality assessment are used to support self-awareness and planning.
The school fosters a strong sense of environmental responsibility through initiatives such as community clean-ups and sustainability projects, reflecting its identity as an eco-conscious institution. Students are encouraged to participate actively in school life from Secondary 1 onwards, with CCA involvement and peer mentoring helping to build a sense of belonging during the transition from primary school.

How DeepThink supports Commonwealth Secondary School students
G1, G2, G3 Mathematics support for the national secondary pathway at Commonwealth Secondary School. Classes follow the student's actual Mathematics subject level.
We prepare students for the paper their year sits: O-Level or N-Level, or the Singapore-Cambridge SEC from 2027.
Your child’s posting group sets the level they start Mathematics at. Under Full Subject-Based Banding, they may take it at a different level.
Additional Mathematics support is available for students taking that subject; we check the actual course and assessment requirements.
Classes are capped at 4 students and grouped by learning pace, with practice focused on the gaps shown in schoolwork.

Frequently asked questions
Clear answers for parents
Which Math class suits a Commonwealth Secondary School student?
We teach Mathematics at G1, G2 or G3. We use the student's current Mathematics course, year and schoolwork to choose a class. Students learn with others studying the same course at a suitable pace.
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.
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 Commonwealth Secondary School 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 class 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.
Can families start with a trial class first?
Yes. A trial class helps you see whether our teaching pace and approach suit your child. Trials in existing classes are free. If no class suits your timing, we can arrange a 1-to-1 trial at another time for $30.
